Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. The 1OC-48/STM-16 SRP line card consists of a printed circuit card that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive ESD strap whenever you are handling a line card.
Following are guidelines for preventing ESD damage:
 |
Caution For safety, periodically check the resistance value of the ESD strap. The measurement should be between 1 and 10 megohms. |
The Cisco 12000 series Gigabit Switch Routers provide high-speed, high-volume routing of packets and ATM cells. The Cisco 12000 series includes the following platforms, all sharing a similar architecture:
The Cisco 12000 series GSR architecture offers the following features and capabilities in providing support to IP-based local-area networks (LANs) and wide-area networks (WANs):
|
Note In addition, the system allows for redundant, field-replaceable units (FRUs). |
The 1OC-48/STM-16 SRP line card has a pair of OC-48c, fiber-optic standard connector (SC) duplex ports that provide an SC connection for either the single-mode short-reach or single-mode long-reach version.
|
Note To implement an SRP ring, you must install two 1OC-48/STM-16 SRP line cards in a Cisco 12000 series router. |
The 1OC-48/STM-16 SRP line card allows networks to:
Figure 1 shows two 1OC-48/STM-16 SRP line cards and the backplane connectors.
Each 1OC-48/STM-16 SRP line card has a front panel D-type connector with 8 mini-coaxial connectors. It connects to a copper coaxial cable that mates two 1OC-48/STM-16 SRP line cards. For this reason, the copper coaxial cable is also referred to as a mate cable.
The mate cable allows 1OC-48/STM-16 SRP line cards to:
Be sure to use two hands to bend the straight mate cable into a U-shape and connect it to the 1OC-48/STM-16 SRP line cards. (See Figure 2 and Figure 3.)
|
Caution Do not bend the mate cable any more than necessary. Never bend one side of the mate cable when you disconnect the cable. Attach and remove both sides of the mate cable as a unit. When you remove the mate cable from both 1OC-48/STM-16 SRP line cards, the system will pick line card side A or line card side B and enter a wrap automatically. |
Each 1OC-48/STM-16 SRP line card is hot swappable and provides redundancy that allows you to remove one line card, while your router retains presence on the SRP ring with the second line card that remains installed in the chassis.
|
Note Although the 1OC-48/STM-16 SRP line cards are slot independent, the adjacent router slot must always be available for a second 1OC-48/STM-16 SRP line card so that you can create a two-fiber ring. |
When you connect two 1OC-48/STM-16 SRP line cards with a mate cable and the RACs are synchronized, they create a two-fiber ring without any wraps. When the RACs on the 1OC-48/STM-16 SRP line cards are unsynchronized, they automatically create a two-fiber ring that is in wrapped mode.
Figure 4 shows synchronized and unsynchronized conditions on an SRP ring.
The LEDs on the 1OC-48/STM-16 SRP line card indicate the conditions on the SRP ring. See the "Interface and Port Status LEDs" section for details. To synchronize the 1OC-48/STM-16 SRP line cards, see the "Troubleshooting" section.
|
Note If the wrap LED on the line card goes on due to an unsynchronized signal fail, reseat the mate cable or replace it. |
When the line cards are not connected by the mate cable, each 1OC-48/STM-16 SRP line card is the equivalent of a single-fiber SRP ring on side B. The single-fiber SRP ring has a wrap at each end to ensure that all data packets will reach their destination. (See Figure 5.)
This section provides information to help you prepare to install and configure the 1OC-48/STM-16 SRP line card and contains safety and ESD-prevention guidelines. The following sections describe prerequisites and preparation information:
|
Note The 1OC-48/STM-16 SRP line cards may be installed in any router slots, except those reserved for CSCs and the GRP. Apart from the reserved slots, you can use any two adjacent slots that can accommodate a pair of 1OC-48/STM-16 SRP line cards. |
You need the following tools and parts on the list to remove and replace a 1OC-48/STM-16 SRP line card. If you need additional equipment, contact your service representative for ordering information.
|
Note If you need additional equipment, contact your service representative for ordering information. |
We recommend that you do the following before beginning any of the procedures in this publication:
To ensure compatibility with the software, your 1OC-48/STM-16 SRP line card should have a hardware revision level of 73-4039-02 Rev. A0 for single-mode short-reach or 73-4181-02 Rev. A0 for single-mode long-reach. The hardware revision number is printed on a label that is affixed to the component side of the card. You can also display the hardware revision number using the show diag and show hardware commands.
The 1OC-48/STM-16 SRP line card is compatible with any Cisco 12000 series router that is operating with the Cisco IOS Release 12.0(11)S or a later 12.0 S release.
The show version, show diag, and show hardware commands display the current hardware configuration of the router, including the system software version that is currently loaded and running. For complete descriptions of show commands, refer to the Configuration Fundamentals Configuration Guide and Configuration Fundamentals Command Reference publications, which are available on the Documentation CD-ROM, Cisco Connection Online, or as printed copies.

If the display indicates that the system software is running a version earlier than Release 12.0(11)S or that the running GRP microcode is a version earlier than 1.13, check the contents of Flash memory to determine if the required images are available on your system. The show flash command displays a list of all files stored in Flash memory. If you do not have the correct software version, contact Cisco Customer Service.
The SONET specification for fiber-optic transmission defines two types of fiber: single-mode short-reach and single-mode long-reach. Signals can travel farther through single-mode fiber than through multimode fiber.
The maximum distance for single-mode installations is determined by the amount of light loss in the fiber path. Good quality single-mode fiber with very few splices can carry an OC-48/STM-16 long reach signal about 50 miles (80 km). The OC-48/STM-16 short reach signal will travel about 1.2 miles (2 km).
If your environment requires the signal to travel close to the typical maximum distance, use an optical time domain reflectometer (OTDR) to measure the power loss. (See Table 1)
| Optical Interface | Power Budget | Transmit Power | Receive Power | Typical Maximum Distance |
|---|---|---|---|---|
Single-mode | 8 dB | -18 to 0 dBm | 2 km | |
Single-mode | 26 dB | -2 to +3 dBm | -28 to -9 dBm | 80 km |
| 1dBm = decibels per milliwatt 2nm = nanometer |
The 1OC-48/STM-16 SRP line card is available with the memory options described in Table 2 and Table 3. Refer to the publication Cisco 12000 Series Gigabit Switch Router Memory Replacement Instructions for installation procedures if you are upgrading or replacing line card memory.

This section describes the line card slot locations in the following Cisco 12000 series routers:
Before installing your line card into the router, verify that two adjacent line card slots are available.
|
Note The 1OC-48/STM-16 SRP line cards may be installed in any router slots, except those reserved for clock schedulers and the GRP. Apart from the reserved slots, you can use any two adjacent slots that can accommodate a pair of 1OC-48/STM-16 SRP line cards. |
The Cisco 12016 GSR chassis has three integral card cages: the upper card cage, the lower card cage, and the switch fabric card cage. You can install line cards in the upper or lower card cage.
The upper card cage has eight user-configurable slots that support the following types of cards in the quantities indicated:
|
Note If the router is equipped with an optional, redundant GRP, it must be installed in the far left slot of the lower card cage (slot 8). If the router is not equipped with an optional, redundant GRP, a line card can be installed in slot 8 of the lower card cage. |
The lower card cage in the Cisco 12016 GSR has eight user-configurable slots, numbered 8 through 15, that support the following types of cards in the quantities indicated:
|
Note The lower card cage is an inverted, or head-down, copy of the upper card cage, meaning cards are installed the same way they are installed in the upper card cage, but in an inverted or head-down orientation. |
Figure 6 shows the location of the line card slots in the Cisco 12016 GSR.
Figure 7 shows the location of the line card slots in the Cisco 12012 GSR. The Cisco 12012 GSR upper card cage contains 12 slots that accommodate Gigabit Route Processors (GRPs) and line cards:
The upper card cage contains ten slots that accommodate the following types of cards in the quantities indicated:
|
Caution Cisco recommends that you avoid installing the 1OC-48/STM-16 SRP line card in slot 0 and slot 1 in a Cisco 12008 series router, as cooling may not be sufficient at maximum ambient operation. For details on improving cooling, see "Upgrading the Filter Assembly in a Cisco 12008 Series GSR" section. For details on improving cooling, see the Cisco 12008 Gigabit Switch Router Fan Tray Replacement and Upgrade Instructions. |
|
Note The 1OC-48/STM-16 SRP line cards may be installed in any router slots, except those reserved for clock schedulers and the GRP. Apart from the reserved slots, you can use any two adjacent slots that can accommodate a pair of 1OC-48/STM-16 SRP line cards. |
Figure 8 shows the location of the line card slots in the Cisco 12008 router.
The Cisco12008 series GSR requires an air filter assembly upgrade to improve cooling. The upgrade kit part number is GSR8-FLTASM-UPG. For instructions on upgrading the filter assembly, refer to the publication, Cisco 12008 Gigabit Switch Router Fan Tray Replacement and Upgrade Instructions.
If you are upgrading the fan filter assembly, you will install a new air filter assembly as shown in Figure 9.
Use a single-mode fiber-optic interface cable to connect your Cisco 12000 series router to another router or switch. In general, single-mode cables are yellow.
|
Note Single-mode fiber-optic cables are available from the following cable vendors: AMP, Anixter, AT&T, Red-Hawk, and Siemens. These cables are not available from Cisco Systems. |
For SONET/SDH single-mode fiber-optic connections, use two Simplex SC-type connectors (see Figure 10).
Attach two simplex fiber cables between the line card and the device to which the line card is connected. Observe the receive (Rx) and transmit (Tx) cable relationship shown in Figure 11.
|
Warning Because invisible radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures. |
|
Warning Class 1 laser product (single-mode short-reach). |
|
Warning Class 1 laser product (single-mode long-reach). |
|
Note The fiber-optic connectors must be free of dust, oil, and other contaminants. Carefully clean the fiber-optic connectors using a fiber cleaning kit. |
The cable-management system in the Cisco 12000 series router organizes the interface cables entering and exiting the system, keeping them out of the way and free of sharp bends. Excessive bending in an interface cable can degrade performance and possibly harm the cable.
The cable-management system consists of two separate components:
Figure 12 shows a cable-management bracket that can be mounted on a Cisco 12012 GSR.
Figure 13 shows the cable-management tray and a line card cable-management bracket on a Cisco 12012 chassis. The cable-management tray on the Cisco 12008 is similar in form and function to the tray on the Cisco 12012.
The Cisco 12016 has a cable-management tray for the upper card cage that is positioned above the upper line card slots, and a cable-management tray for the lower card cage that is positioned below the lower line card slots. In addition, there are vertical cable troughs on either side of the card cages that keep the cables organized and secured (see Figure 14).
This section describes the procedures for installing or replacing a 1OC-48/STM-16 SRP line card and contains the following procedures:
See the following section, "Guidelines for Line Card Removal and Installation," before removing a line card while power to the system is on.
|
Note The procedures in the following sections use illustrations of a Cisco 12012 GSR to support the descriptions of installing and removing line cards. Although the card cages of the Cisco 12000 series routers differ in the number of card slots, the designated use of slots and the process of installing and removing a line card are basically the same. Therefore, separate procedures and illustrations for the Cisco 12016 GSR and Cisco 12008 GSR are not included in this publication. |
|
Note Do not use a shutdown command before you replace a single 1OC-48/STM-16 SRP line card. When you remove both sides of the mate cable, the line card will automatically enter wrap mode on the remaining line card and create half an SRP ring (see Figure 4). Before you remove both 1OC-48/STM-16 SRP line cards, Cisco recommends that you use the shutdown command to disable the SRP interface to prevent anomalies when you reinstall two new or reconfigured 1OC-48/STM-16 SRP line cards. When you shut down an SRP interface, it is designated as administratively down in the show command display. |
|
Caution To avoid erroneous failure messages, remove or insert only one line card at a time. Also, after inserting or removing a line card, allow at least 15 seconds before removing or inserting another line card, so that the system can reinitialize and note the current configuration of all interfaces. |
You can remove and replace line cards while the system is operating; you do not need to reconfigure the software or reset the system power. This functionality allows you to add, remove, or replace line cards with the system online, which provides a method that is seamless to end users on the network, maintains all routing information, and ensures session preservation.
When you reinstall a line card, the system automatically downloads the necessary software from the GRP. After that, the system brings online only those interfaces that match the current configuration and that were previously configured as up.
|
Caution The system can indicate a hardware failure if you do not follow proper procedures. Remove or insert only one line card at a time. Allow at least 15 seconds for the system to complete the preceding tasks before removing or inserting another line card. |
Each line card has two ejector levers that allow you to release the card from its backplane connector when you are removing the line card, and to firmly seat the line card in its backplane connector when you are installing the line card. The ejector levers align and seat the card connectors in the backplane.
When you remove a line card, always use the ejector levers to ensure that the card connector pins disconnect from the backplane. Any card that is only partially connected to the backplane will halt the system.
Similarly, when you install a line card, always use the ejector levers to ensure that the card is correctly aligned with the backplane connector, the card connector pins make contact with the backplane in the correct order, and the card is fully seated in the backplane. A card that is only partially seated in the backplane can cause the system to hang and subsequently crash.
This section describes removing or replacing 1OC-48/STM-16 SRP line cards and contains the following procedures:
Follow these steps to replace a single 1OC-48/STM-16 SRP line card:
Step 2 Remove the mate cable completely from both line cards.
|
Note Do not bend the mate cable any more than necessary. Never bend one side of the mate cable when you disconnect the cable. Attach and remove both sides of the mate cable as a unit. When you remove the mate cable from both 1OC-48/STM-16 SRP line cards, the system will pick a side and enter a wrap automatically (see Figure 5). |
Step 3 Remove the existing card first.
Step 4 Install the new 1OC-48/STM-16 SRP line card in the same slot.
Step 5 Connect the fiber cables from the 1OC-48/STM-16 SRP line card Tx and Rx ports.
Step 6 Reattach the mate cable to both 1OC-48/STM-16 SRP line cards.
|
Caution Be aware that if you remove both 1OC-48/STM-16 SRP line cards from a router at the same time, you are removing the router from the SRP ring. When you insert new 1OC-48/STM-16 SRP line cards, you will have to reconnect the nodes on the SRP ring. |
Follow these steps to replace two 1OC-48/STM-16 SRP line cards:
Step 2 Remove the fiber cables from the 1OC-48/STM-16 SRP line card Tx and Rx ports first before removing the mate cable.
Step 3 Remove the mate cable completely from both line cards.
|
Note Do not bend the mate cable any more than necessary. Never bend one side of the mate cable when you disconnect the cable. Attach and remove both sides of the mate cable as a unit. |
Step 4 Remove each line card.
Step 5 Install each new 1OC-48/STM-16 SRP line card in the same slot.
Step 6 Reattach the mate cable.
Step 7 Use the no shutdown srp slot/port command to bring up the SRP interface in each slot.
Step 8 Reconnect the nodes on the SRP ring.
Follow these steps to remove two 1OC-48/STM-16 SRP line cards in your system configuration:
Step 2 Remove the fiber cables from the 1OC-48/STM-16 SRP line card Tx and Rx ports first before removing the mate cable.
Step 3 Remove the mate cable completely from both line cards.
|
Note Do not bend the mate cable any more than necessary. Never bend one side of the mate cable when you disconnect the cable. Attach and remove both sides of the mate cable as a unit. When you remove the mate cable from both 1OC-48/STM-16 SRP line cards, the system will pick a side and enter a wrap automatically. |
Step 4 Remove each 1OC-48/STM-16 SRP line card.
Step 5 Install the new line cards.
Step 6 Use the appropriate interface command (for example, interface pos slot/port) to start configuring each new line card.
The Gigabit Switch Router supports online line card insertion and removal, which means that you can remove and replace line cards while the system remains powered up. To remove a line card, refer to Figure 15 as a reference and perform the following steps:
|
Note Do not use a shutdown command before you replace a single 1OC-48/STM-16 SRP line card. When you remove both sides of the mate cable, the line card will automatically enter wrap mode on the remaining line card and create half an SRP ring. (See Figure 4.) Before you remove both 1OC-48/STM-16 SRP line cards, Cisco recommends that you use the shutdown command to disable the SRP interface to prevent anomalies when you reinstall two new or reconfigured 1OC-48/STM-16 SRP line cards. When you shut down an SRP interface, it is designated as administratively down in the show command display. |

Caution When you remove a line card, always use the ejector levers to ensure that the card connector pins disconnect from the backplane. Any card that is only partially connected to the backplane will halt the system. |
Step 2 Simultaneously pivot the ejector levers away from each other to release the line card from the backplane connector. (See Figure 15b.)
Step 3 Grasp the ejector levers and pull the line card half-way out of the slot.
Step 4 Grasp the line card faceplate with one hand and pull the line card straight out of the slot, keeping your other hand under the line card to guide it. (See Figure 15c.) Avoid touching the line card printed circuit board, components, or any connector pins.
Step 5 Place the removed line card on an antistatic mat or foam pad, or place it in an antistatic bag if you plan to return it to the factory.
If the line card slot is to remain empty, install a line card blank (Cisco product number 800-03004-01) to keep dust out of the chassis and to maintain proper airflow through the line card compartment. Secure the line card blank to the chassis by tightening its captive screws.
To remove line card interface cables, use Figure 16 as a reference and perform the following steps:
|
Note Do not use a shutdown command before you remove a single 1OC-48/STM-16 SRP line card. When you remove both sides of the mate cable, the line card will automatically enter wrap mode on the remaining line card and create half an SRP ring. (See Figure 4) Before you remove both 1OC-48/STM-16 SRP line cards, Cisco recommends that you use the [no] shutdown command to disable the SRP interface to prevent anomalies when you reinstall two new or reconfigured 1OC-48/STM-16 SRP line cards. When you shut down an SRP interface, it is designated as administratively down in the show command display. |
Step 2 Disconnect and remove the line card interface cables and line card cable-management bracket (See Figure 16.)
a. Disconnect the interface cable connectors from the line card interface ports.
b. Use a Phillips screwdriver to loosen the captive installation screws at the ends of the line card cable-management bracket.
c. Detach the line card cable-management bracket from the line card and set it aside.
|
Note Do not remove the interface cables from the line card cable-management bracket. The bracket is equipped with a small hook on one end for hanging the bracket and cables from the cable-management tray or bracket on the chassis. |
You can install two 1OC-48/STM-16 SRP line cards in any two adjacent line card slots. There are no restrictions on line card position on the Cisco 12016 series GSR or the Cisco 12012 series GSR. Although you can install a line card in slot 0, Cisco recommends that you adopt the convention of reserving slot 0 for the GRP.
For information on line card slot locations, refer to the section "Cisco 12000 Series Line Card Slot Locations" section.
If you install a new line card, you must first remove the line card blank from the available slot. Refer to the procedures in the section "Installing a Line Card" section.
When you first install a pair of 1OC-48/STM-16 SRP line cards, always ensure that the first 1OC-48/STM-16 SRP line card is inserted into the lowest slot number first. The 1OC-48/STM-16 SRP line card in the lower numbered slot is referred to as the first card in the pair of 1OC-48/STM-16 SRP line cards, and is referred to as side A. The second 1OC-48/STM-16 SRP line card in the higher numbered slot is referred to as side B.
For example, assume that a pair of 1OC-48/STM-16 SRP line cards is present in slots 4 and 5. The line card in slot 4 is the first card of the pair of 1OC-48/STM-16 SRP line cards (side A), and the line card in slot 5 is the second card (side B).
When two 1OC-48/STM-16 SRP line cards are connected by a mate cable, they behave as one interface and share one IP address. You must enter the hw-module slot number srp configuration command to enable the paired line cards.
|
Note Do not use a shutdown command before you replace a single 1OC-48/STM-16 SRP line card. When you remove both sides of the mate cable, the line card will automatically enter wrap mode on the remaining line card and create half an SRP ring (see Figure 4). Remove the fiber cables first, before disconnecting the mate cable to prevent anomalies. Before you remove both 1OC-48/STM-16 SRP line cards, Cisco recommends that you use the shutdown command to disable the SRP interface to prevent anomalies when you reinstall two new or reconfigured 1OC-48/STM-16 SRP line cards. When you shut down an SRP interface, it is designated as administratively down in the show command display. |
|
Caution The system can indicate a hardware failure if you do not follow proper procedures. Remove or insert only one line card at a time. Allow at least 15 seconds for the system to complete the preceding tasks before removing or inserting another line card. |
Use the following steps to install two 1OC-48/STM-16 SRP line cards in slot 4 and 5 of a Cisco 12000 series router. These steps assume that you are installing the two 1OC-48/STM-16 SRP line cards in slot 4 and slot 5:
Step 2 Attach an ESD wrist strap to your wrist and to the ESD connection socket on the chassis or to a bare metal surface on the chassis or frame.
Step 3 Use the hw-module slot 4 srp configuration command to enable the SRP interface. This command will prevent any anomalies to the running configuration if you install a 1OC-48/STM-16 SRP line card in slot 5 first.
Step 4 Insert the first line card in slot 4. There will be a slight delay while the line card initializes.
Step 5 Insert the second line card in slot 5. There will be a slight delay while the line card initializes.
Step 6 Connect the mate cable to each 1OC-48/STM-16 SRP line card.
|
Note Do not bend the mate cable any more than necessary. Never bend one side of the mate cable when you disconnect the cable. Attach and remove both sides of the mate cable as a unit. When you remove the mate cable from both 1OC-48/STM-16 SRP line cards, the system will pick a side and enter a wrap automatically. |
Step 7 Plug the simplex SC cable connectors into each 1OC-48/STM-16 SRP line card port.
|
Caution To prevent ESD damage, handle line cards by the card carrier edges only. |
Step 8 Grasp the faceplate of the line card with one hand and place your other hand under the card carrier to support the weight of the card; position the card for insertion into the card cage slot. Avoid touching the line card printed circuit board, components, or any connector pins.
Step 9 Carefully slide the line card into the slot until the ejector levers make contact with the edges of the card cage, then stop. Make sure the ejector lever hooks catch the lip of the card cage. (See Figure 17.)
|
Caution When you install a line card, always use the ejector levers to ensure that the card is correctly aligned with the backplane connector, the card connector pins make contact with the backplane in the correct order, and the card is fully seated in the backplane. A card that is only partially seated in the backplane can cause the system to hang and subsequently crash. |
Step 10 Simultaneously pivot both ejector levers toward each other until they are perpendicular to the line card faceplate. This action firmly seats the card in the backplane.
Step 11 Use a Phillips screwdriver to tighten the captive screw on each end of the line card faceplate to ensure proper EMI shielding and to prevent the line card from becoming partially dislodged from the backplane. (These screws must be tightened to meet EMI specifications.)
|
Caution To ensure adequate space for additional line cards, always tighten the captive installation screws on each newly installed line card before you insert any additional line cards. These screws also prevent accidental removal and provide proper grounding and EMI shielding for the system. |
Step 12 Reinstall the line card cable-management bracket (see Figure 13, previously shown):
a. Unhook the line card cable-management bracket from the chassis cable-management tray or bracket.
b. Position the line card cable-management bracket over the front of the line card faceplate.
c. Insert and tighten the captive screw at each end of the line card cable-management bracket to secure the bracket to the line card.
Step 13 Plug the Simplex SC cable connectors into their original ports on the line card faceplate.
|
Note To configure the 1OC-48/STM-16 SRP line cards as a single SRP interface, see "Initial Configuration for a 1OC-48/STM-16 SRP Line Card,". |
This section contains the following procedures:
The following procedures assume that you have installed a new line card in the router. You must also install a line card cable-management bracket on the line card.
To install a line card cable-management bracket on a line card, perform the following steps:
Step 2 Attach the line card cable-management bracket to the line card as follows:
a. Position the line card cable-management bracket over the front of the line card faceplate.
b. Insert and tighten the captive screw at each end of the line card cable-management bracket to secure the bracket to the line card.
Step 3 Starting with the bottom port on the line card (see Figure 18a), connect each interface cable to the intended port.
Step 4 Carefully press the interface cable into the cable clip on the end of the cable standoff, as shown in Figure 18b. Avoid any kinks or sharp bends in the cable. (Excessive bending in an interface cable will degrade performance.)
Step 5 Proceeding upward, carefully press the interface cable into the cable-routing clips along the base of the line card cable-management bracket, as shown in Figure 18b.
Step 6 Repeat Step 3 through Step 5 for all of the interface cables on the line card ports.
To remove the interface cables from a line card cable-management bracket and remove the cable-management bracket from a line card, perform the following steps:
Step 2 On the site log, note the current interface cable connections to the ports on each line card.
Step 3 Starting with the interface cable for the bottom port on the line card (for cards with multiple ports), disconnect the cable from the line card port (see Figure 19a).
Step 4 Proceeding upward, remove the interface cable from the cable clip on the end of the cable standoff (see Figure 19b).
Step 5 Remove the interface cable from the cable-routing clips along the base of the line card cable-management bracket (see Figure 19b).
Repeat Step 3 through Step 5 for any other interface cables on the line card ports, then proceed to Step 6.
Step 6 Loosen the captive installation screw at each end of the line card cable-management bracket and remove the bracket from the line card.
The section describes how to verify or troubleshoot line card installation and contains the following procedures:
During a typical line card boot process, the following events occur:
To verify that the line card is working properly, perform the following operational checks:
After you install the line card and connect the interface cables, verify that the line card is working properly by checking the LEDs on the faceplate.
This section describes the following types of LEDs on the 1OC-48/STM-16 SRP line card:
The interface and port status LEDs on the line card might not go on until you have configured the line card interfaces (or turned them on, if they were shut down). In order to verify correct operation of each interface, complete the configuration procedures for the line card (See "Configuring Interfaces on the 1OC-48/STM-16 SRP Line Card" section").
Next to each port on the 1OC-48/STM-16 SRP line card are three green LEDs: Active, Carrier, and Rx Pkt. (See Figure 20.) These LEDs signal the port status, as explained in Table 3.
| LED State | Explanation | ||
| Active | Carrier | Rx Pkt | |
On | On | Off | Line card is up, but no SRP packets received by line card. |
On | On | On | Line card is functioning normally and receiving packets. |
Off | On | Off | Line card is in wrap state. |
Off | Off | Flashing | Data is being transmitted or received. |
This section how to interpret the LEDs that indicate the status of the SRP interface on the ring. Figure 21 shows the location of the SRP Ring LEDs on the 1OC-48/STM-16 SRP line card.
The pass-through LED is located between the status LEDs and the alphanumeric LEDs. The pass-through LED indicates whether or not a fiber failure has occurred (see Table 4).
| LED State | Explanation |
Green | Packets are passing through transparently. |
Off | Line card is operating in normal mode. |
The Wrap LED is located between the sync and pass-through LEDs. The wrap LED indicates whether a wrap is present on the fiber (see Table 6).
| LED Display | Explanation |
Green | A wrap is present on the ring fiber. |
Off | Line card is operating in normal mode. |
The Synch LED is located next to the Wrap and pass-through LEDs. The Synch LED indicates that the ring access controllers on each 1OC-48/STM-16 SRP line card are synchronized and the mate cable is properly connected.
| LED Display | Explanation | Source |
Green | The RACs on the 1OC-48/STM-16 SRP line cards are synchronized when connected by a mate cable. | GRP IOS Software |
Off | The RACs on the 1OC-48/STM-16 SRP line cards are unsynchronized when connected by a mate cable. | GRP IOS Software |
Admin Down | Interface in shutdown state or hw-module slot number srp command missing from configuration. | GRP IOS Software |
The 1OC-48/STM-16 SRP line card has two, 4-digit alphanumeric LED displays at one end of the faceplate, near the ejector lever, that display a sequence of messages telling you the state of the card. In general, the LEDs do not turn on until the GRP recognizes and powers up the card. It is normal for a message displayed as part of a sequence or process to appear too briefly to read. See Table 8.

If the Active LED on a line card does not come on, verify the following conditions:
To verify that the line card is connected correctly, perform the following procedure:
Step 2 When the reinitialization is complete, verify that the Active LED on the 1OC-48/STM-16 SRP line card is on and remains on. If the LED stays on, proceed to Step 6. If the Active LED does not stay on, proceed to the next step.
Step 3 If the active LED on the 1OC-48/STM-16 SRP line card fails to go on, determine if the
board connector is fully seated in the backplane. Loosen the captive installation screws and firmly pivot the ejector levers toward each other until both are perpendicular to the 1OC-48/STM-16 SRP line card faceplate. Tighten the captive installation screws.
After the system reinitializes the interfaces, the Active LED on the 1OC-48/STM-16 SRP line card should go on. If the Active LED goes on, proceed to Step 6. If the active LED does not go on, proceed to the next step.
Step 4 If the Active LED still fails to go on, remove the 1OC-48/STM-16 SRP line card and try installing it in another available line card slot.
|
Note Do not bend the mate cable any more than necessary. Never bend one side of the mate cable when you disconnect the cable. Attach and remove both sides of the mate cable as a unit. When you remove the mate cable from both 1OC-48/STM-16 SRP line cards, the system will pick a side and enter a wrap automatically. |
Step 5 Use the show running configuration EXEC command to determine if the SRP interface is administratively down. If the SRP interface is disabled, enter the hw-module slot number srp configuration command to enable the SRP interface. The problem may have occurred if you installed a 1OC-48/STM-16 SRP line card in side B first.
Step 6 Use the show interface srp command to verify the status of the SRP interface. (If the SRP interface is not configured, you must use the procedures in the section "Configuring Interfaces on the 1OC-48/STM-16 SRP Line Card.")
If an error message displays on the console terminal, refer to the appropriate reference publication for error message definitions. If you experience other problems that you are unable to solve, contact a service representative for assistance.
For more information on troubleshooting and diagnostics, consult the Installation and Configuration Guide that came with your Cisco 12000 series router.
This section provides procedures and configuration examples to configure the 1OC-48/STM-16 SRP line card. The command line interface (CLI) is provided to configure and display parameters for both the DPT and the SONET/SDH framer.
This section contains the following procedures:
The following procedure is for creating a basic configuration, enabling an SRP interface, and specifying IP routing. You can also need to enter other configuration commands, depending on the requirements of your system configuration. For descriptions of configuration commands and the configuration options available, refer to the appropriate software publications listed in the "Important Information" section.
A Cisco 12000 series router identifies an SRP interface address by its line card slot number and port number, in the format slot/port. For example, the slot/port address of an SRP interface on a 1OC-48/STM-16 SRP line card installed in line card slot 4 and port 0 is 4/0.
When two 1OC-48/STM-16 SRP line cards are connected by a mate cable, they behave as one SRP interface and share one IP address. You must execute the hw-module slot number srp configuration command to enable the paired line cards.
|
Note Side A is automatically the left-most slot of the pair of 1OC-48/STM-16 SRP line cards. |
To initially configure two 1OC-48/STM-16 SRP line cards in slot 4 and 5 of a Cisco 12000 series router, perform the following steps:
Router> enable Router#
Step 2 Enter the show running configuration command to verify that initially both 1OC-48/STM-16 SRP line cards are shut down by reading the output.
Router# show running configuration ....... hw-module slot 4 shutdown hw-module slot 5 shutdown
Step 3 Enter the configure terminal command to enter configuration mode.
Router# configure terminal Router (config)#
Step 4 Enter the hw-module slot number srp configuration command to bring up the each 1OC-48/STM-16 SRP line card.
Router (config)# hw-module 4 srp Router (config)# end Router#
where # is the slot number of the left-most 1OC-48/STM-16 SRP line card, or side A.
Step 5 Write the new configuration to nonvolatile random access memory (NVRAM) by using the copy running-config startup-config command:
Router# copy running-config startup-config [OK] Router#
Step 6 Use the show gsr command to monitor stages of the IOS download to the line cards.
Router# show gsr
Slot 0 type = Route Processor
state = IOS Running PRIMARY
Slot 4 type = 1 Port SONET based SRP OC-48c/STM-16
state = Line Card Enabled
Slot 5 type = 1 Port SONET based SRP OC-48c/STM-16
state = Line Card Enabled
Slot 17 type = Clock Scheduler Card(8)
state = Card Powered PRIMARY CLOCK
Slot 18 type = Switch Fabric Card(8)
state = Card Powered
Slot 19 type = Switch Fabric Card(8)
state = Card Powered
Slot 20 type = Switch Fabric Card(8)
state = Card Powered
Slot 26 type = AC Power Supply(8)
state = Card Powered
Router#
When the Cisco IOS software is successfully downloaded, the LED status is "IOS RUN."
The following procedure is for creating a basic configuration—enabling an interface and specifying IP routing. You might also need to enter other configuration commands, depending on the requirements of your system configuration. For descriptions of configuration commands and the configuration options available, refer to the appropriate software publications listed in the "Important Information" section.
After you verify that the new 1OC-48/STM-16 SRP line card is installed correctly (the Active LED goes on), you must enter the privileged EXEC command mode by using the enable command. The system will prompt you for a password if one is set. Use the configure command to configure the new interface.
A Cisco 12000 series router identifies an interface address by its line card slot number and port number, in the format slot/port. For example, the slot/port address of an interface on a 1OC-48/STM-16 SRP line card installed in line card slot 1 and chassis port 0 is 1/0. Even though the card contains only one port, you must use the slot/port notation.
Use the configure terminal command to enter the configuration mode if you want to change the default configuration values on the 1OC-48/STM-16 SRP line card. Be prepared with the information you will need, such as the IP address (see Table 10).
| Parameter | Configuration Command | Default Value |
|---|---|---|
Cisco Discovery Protocol (CDP) | [no] cdp enable | cdp enable |
Framing | srp framing {sdh | sonet} [a | b] | SONET OC-48c |
Bandwidth | [no] bandwidth Gbps | 2.5 Gbps |
SONET overhead | srp flag {c2 | j0 | s1s0} value [a | b] | c2 set to 0x16; |
Clock source | srp clock-source {internal | line} [a | b] | srp clock-source internal |
Use the following procedure to configure the 1OC-48/STM-16 SRP line card. Press the Return key after each configuration step, unless otherwise noted.
Router# show version Router#
For an example of output from the show version command, see the section "Using Show Commands to Check System Status" later in this publication.
Step 2 Check the status of each port by entering the show interface srp slot/port command.
Router# show interface srp 4/0 Router#
For an example of output from the show interface command, see the section "Using Show Commands to Check System Status," later in this publication.
Step 3 Enter configuration mode and specify that the console terminal will be the source of the configuration commands.
Router# configure terminal Router(config)#
Step 4 Enable IP routing by entering the ip routing command.
Router(config)# ip routing Router(config)#
Step 5 At the prompt, specify the new interface to configure by entering the interface command, followed by the type (srp), and slot/port (line card slot number/port number). The example that follows is for a 1OC-48/STM-16 SRP line card in chassis slot 1, port 0.
Router(config)# interface srp 1/0 Router(config-if)#
Step 6 Assign an IP address and subnet mask to the interface with the ip address configuration command.
Router(config-if)# ip address 10.0.0.1 255.255.255.0 Router(config-if)#
Step 7 Verify that the default value for the clock source is correct.
The default setting is clock source internal. Typically, when two Cisco 12000 series routers are connected back-to-back, or are connected over dark fiber, where no external clocking is available, set the clock source on each device to internal. If a router is connected to a SONET/SDH ADM, configure the clock-source for clock source line on side A and side B.
Router(config-if)# srp clock-source line a Router(config-if)# Router(config-if)# srp clock-source line b Router(config-if)#
Step 8 Change the shutdown state to up and enable the interface.
Router(config-if)# no shutdown Router(config-if)#
The no shutdown command passes an enable command to the 1OC-48/STM-16 SRP line card. It also causes the line card to configure itself automatically, based on the previous configuration commands sent.
|
Note The line card cable is connected to both a Cisco 12000 series device and a high-end router or switch. Steps 10 to 12 apply to both the Cisco 12000 series device and the other device. |
Step 9 Turn off the Cisco Discovery Protocol (CDP).
Router(config-if)# no cdp enable Router(config-if)#
|
Note Cisco 12000 series routers do not require CDP. |
Step 10 To select framing, enter the srp framing interface configuration command.
Router1(config-if)# srp framing sdh Router1(config-if)#
Step 11 Set the topology timer frequency in seconds by entering the srp topology-timer interface configuration command.
Router1(config-if)# srp topology-timer 60 Router1(config-if)#
|
Note All nodes on the SRP ring must have the same wait-to-restore, topology timer, and IPS values. |
Step 12 To control the amount of high and low priority traffic a node can transmit onto the SRP ring, use the srp tx-traffic-rate interface configuration command.
Router1(config-if)# srp tx-traffic-rate high 622 Router1(config-if)# srp tx-traffic-rate low 1866 Router1(config-if)#
Step 13 To control which IP packets get queued in the high and low priority transmit queues, use the srp priority-map transmit interface configuration command with precedence values of 5 to 7 to be queued in the high priority transmit queue, and 0 to 4 to be queued in the low priority transmit queue.
Router1(config-if)# srp priority-map transmit 5 Router1(config-if)#
The no form of this command removes the tx-traffic-rate from the configuration.
Step 14 Add any other configuration commands required to enable routing protocols and adjust the interface characteristics.
Step 15 When you have included all of the configuration commands to complete the configuration, enter ^Z (press the Control key while you press Z) to exit configuration mode.
Step 16 Write the new configuration to memory.
Router1# copy running-config startup-config Router1#
The system displays an OK message when the configuration has been stored.
This section explains how to use SRP IPS command options to insert switches or remove automatic and user-configured switches:
|
Note Before any physical manipulation to the line card, add an srp ips request forced-switch to the side of the ring that is to be changed. |
For example, you can enter a forced-switch command to force data traffic to one side of the ring when a 1OC-48/STM-16 SRP line card is removed from a router slot, or in response to an event. Table 11 provides an explanation of the SRP IPS requests in the order of priority, from highest to lowest.
| SRP IPS Request | Explanation |
|---|---|
Forced-Switch | Adds a high-priority protection switch wrap on each end of a specified span by entering the srp ips request forced-switch command. |
Manual-Switch | Adds a low-priority protection switch wrap on each end of a specified span by entering the srp-ips request manual-switch command. |
If a protection switch is requested for a given span on the ring, the node that receives the protection request issues a protection request to the node on the other end of the span using both the short path over the failed span, as the failure may be unidirectional, and the long path, around the ring.
As the protection requests travel around the ring, the protection hierarchy is applied. For example, if a high-priority signal fail (SF) request enters the ring, it overrides a pre-existing lower-priority signal degrade (SD) request. If an event or a user-configured command enters a low-priority request, it is not allowed if a high-priority request is present on the ring.
|
Note An exception is that multiple signal fail and forced-switch requests can coexist on the SRP ring. |
All protection switches are performed bidirectionally and enter wraps at both ends of a span for transmit and receive directions, even if a failure is only unidirectional.
Router# configure terminal Router(config)#
Step 2 At the prompt, specify the new interface to configure by entering the interface command, followed by the type (srp), and slot/port (line card slot number/port number). The example that follows is for a 1OC-48/STM-16 SRP line card in chassis slot 1, port 0. The prompt changes to interface configuration mode.
Router(config)# interface srp 1/0 Router(config-if)#
Step 3 Enter a user-configured manual-switch or forced-switch wrap.
Router(config-if)# srp ips request manual-switch a Router(config-if)#
|
Note A manual-switch does not appear in the show running configuration command output. |
Router(config-if)# srp ips request forced-switch a Router(config-if)#
|
Note A forced-switch will override a signal degrade. |
Step 4 To set a non-default value of the wait-to-restore timer, enter the srp ips wait-to-restore timer interface configuration command and the value in seconds.
Router(config-if)# srp ips wtr-timer 60 Router(config-if)#
|
Note All nodes on the SRP ring should have the same wait-to-restore, topology timer, and IPS values. |
Step 5 To set a non-default value for the frequency of IPS messages to display, enter the srp ips timer interface configuration command and specify the value in seconds.
Router(config-if)# srp ips timer 90 Router(config-if)#
Step 6 Type end until you return to the privileged EXEC mode.
Router(config-if)# end Router#
Step 7 Write the new configuration to memory.
Router1# copy running-config startup-config Router1#
The system displays an OK message when the configuration has been stored.
Step 8 Use the show srp 1/0 EXEC command to display the status of the srp ips requests.
Router# show srp 1/0 Router#
This section shows an example of configuration file commands for a Cisco 12000 series router with one SRP interface in slot 2/port 0:
First Router:
Router# interface srp 2/0 ip address 10.0.0.1 255.255.255.0 no shutdown no cdp enable no ip mroute-cache
Each line card for the Cisco 12000 series maintains information about its configuration, traffic, errors, and so on. You access this information by using the show commands. Following are descriptions and examples of the show commands that display line card information and system status.
