This publication contains instructions for installing and configuring the Cisco channelized OC-12 line card on a Cisco 10000 Edge Services Router (ESR). If you are not familiar with the Cisco 10000 router, see the Cisco 10000 ESR System Description, and the Cisco 10000 ESR Hardware Installation Guide for additional information.
The following sections are included in this configuration guide:
The channelized OC-12 line card uses fractional T1 (nxDSO), DS-1, and DS3 IP services to connect ISP customers to the network backbone after consolidation by digital cross connect systems (DXCs) into OC-12 links. It provides full duplex operation at OC-12 bandwidth rates using a (singlemode) fiber optic port that provides the Cisco 10000 ESR with a single interface that connects up to 768 individual channelized options (Figure 1).
Before you perform any of the procedures in this guide, Cisco recommends that you do the following:
Before you begin the line card installation procedure, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment. Before you install, configure, or perform maintenance on the router, you should also review the safety warnings listed in the Cisco 10000 ESR Hardware Installation Guide.
Safety warnings appear throughout this publication in procedures that, if performed incorrectly, may harm you. A warning symbol precedes each warning statement. The following warning is an example of a safety warning. It identifies the warning symbol and associates it with a bodily injury hazard.
 |
Warning This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device. |
 |
Note If you need translations of the safety warning, see the Cisco 10000 ESR Hardware Installation Guide. |
This section contains guidelines for the following:
The Cisco 10000 system is hot-swappable, which means you can remove and replace line cards while the system is operating. It is not necessary to notify the software or reset the system power. This feature allows you to add, remove, or replace line cards while the system maintains all routing information and ensures session preservation.
 |
Caution To avoid erroneous failure messages, remove or insert only one line card at a time. Also, after you insert or remove a line card, allow at least 15 seconds before you insert or remove another line card so that the system can reinitialize and note the current configuration of all interfaces. |
|
Caution To prevent electrostatic discharge (ESD) damage, handle line cards by the faceplate or the card carrier edges only. Avoid touching the line card printed circuit board, components, or any connector pins. |
You must configure all new installations of the channelized OC-12 line card using the configure command. For configuration information, refer to the "Configuring the Line Card" section.
If a channelized OC-12 line card is replaced (in the same slot), the system automatically downloads the necessary configuration information from the PRE; there is no need to configure the new line card. After the information is downloaded, the system recognizes only those interfaces that match the previous channelized OC-12 line card configuration (those configured as Up).
You need the following tools and equipment to install the channelized OC-12 line card:
This section describes how to install or replace the channelized OC-12 line card in the Cisco 10000 chassis. It contains the following procedures:
Use the following procedure to remove the front cover from the system. If your system does not use a front cover, go to "Installing a Channelized OC-12 Line Card" section.
Repeat this procedure for all four bezel plugs and then remove the plugs.
Step 2 Remove the cover by lifting it up slightly and then pulling it toward you (Figure 3).
Use the following procedure to install the channelized OC-12 line card into any of the eight line card slots (slots 1 through 4 and slots 5 through 8) available in the Cisco 10000 chassis.
|
Note If you are replacing a channelized OC-12 line card, see the "Removing a Channelized OC-12 Line Card" section before you begin this procedure. |
Step 2 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 in front of the card cage slot.
Step 3 Carefully align the upper and lower edges of the line card with the upper and lower guides in the chassis, and slide the line card into the slot until you can feel it begin to seat in the backplane connectors (Figure 5).
Step 4 Simultaneously pivot both ejector levers toward each other (until they are parallel to the faceplate) to firmly seat the card in the backplane (Figure 6).
The line card cycles through its power-on self-test. The Fail LED stays on briefly (10 to 15 seconds) and then shuts off. If the Fail LED remains on, go to the "Troubleshooting the Installation" section.
Step 5 Secure the line card in the chassis by tightening the top and bottom captive screws (Figure 7).
|
Caution To ensure that there is adequate space for additional line cards, always tighten the captive screws on each newly installed line card before you insert any additional line cards. These screws prevent accidental removal and provide proper grounding for electromagnetic interference (EMI) shielding. |
After the channelized OC-12 line card is successfully installed, you can configure the card for network use. For information about configuring the channelized OC-12 line card, see the Cisco 10000 ESR Software Configuration Guide.
|
Note You do not need to configure the channelized OC-12 line card if this is a replacement installation in the same chassis slot. The system automatically downloads the necessary configuration information from the PRE. |
Use the following procedure to remove a channelized OC-12 line card from the chassis:
Step 2 Loosen the top and bottom captive screws on the line card (Figure 9).
Step 3 Simultaneously pivot both ejector levers away from each other to disengage the line card from the backplane (Figure 10).
Step 4 Slide the line card out of the slot and place it on an antistatic surface, or in an antistatic bag.
Step 5 See the "Installing or Replacing a Channelized OC-12 Line Card" section for instructions to install a new line card.
If you are not installing a replacement line card, install a blank faceplate in the slot.
|
Warning Do not operate the system unless all slots contain a line card or a blank faceplate. Blank faceplates are necessary in empty slots to prevent exposure to hazardous voltages, to reduce electromagnetic interference (EMI) that may disrupt other equipment, and to direct the flow of cooling air through the chassis. |
Refer to Figure 11 for descriptions of the LEDs on the channelized OC-12 line card. Follow the instructions in Table 1 on the next page to troubleshoot the installation.
| Symptom | Possible Cause | Corrective Action |

Be sure the ejector levers are fully closed and that the captive screws have been tightened. 2. Remove the line card and install it in another chassis slot. |
Line card does not operate properly | 1. Bad line card slot or backplane connector. 2. Bad line card. | 1. Remove the line card and install it in another chassis slot. 2. Replace the line card. |
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.
