This configuration note contains instructions for installing the MultiChannel Interface Processor (MIP) in the Cisco 7000 family routers: Cisco 7000, Cisco 7010, Cisco 7505, Cisco 7507, and Cisco 7513. This configuration note also contains basic configuration steps and examples. For complete descriptions of interface subcommands and the configuration options available for MIP interfaces, refer to the publications listed in the section "If You Need More Information" on page 2.
Sections in this document include the following:
The Cisco Internetwork Operating System (Cisco IOS) software running the router contains extensive features and functionality. The effective use of many MIP features is easier if you have more information at hand. For additional information on configuring the Cisco 7000 family routers and MIP, the following documentation resources are available to you:
cs-rep@cisco.com. You can also refer to the Cisco Information Packet that shipped with your router.
The MIP, shown in Figure 1, has up to two channelized T1 or E1 connections via serial cables to a channel service unit (CSU). Two controllers can each provide up to 24 T1 channel-groups or 30 E1 channel groups. Each channel group is presented to the system as a serial interface that can be configured individually. The MIP has one or two controllers for transmitting and receiving data bidirectionally at the T1 rate of 1.544 Mbps, or at the E1 rate of 2.048 Mbps. For wide-area networking, the MIP can function as a concentrator for a remote site.
For both T1 and E1, there are no restrictions on slot locations or sequence; you can install the MIP in any available interface processor slot. The term module refers to a MIP card. A MIP module has one or two T1 or E1 adapters. Do not mix T1 and E1 port adapters on a single MIP.
After system initialization, the enabled LED, which is present on all interface processors, turns on to indicate that the MIP is enabled for operation. The following conditions must be met before the MIP is enabled:
If any of these conditions are not met, or if the initialization fails, the enabled LED does not turn on.
There are three LEDs associated with each MIP port that indicate alarm or loop conditions on that port. (See Figure 1.) The three LEDs above each MIP port indicate the following:
The MIP microcode is a software image that provides card-specific software instructions. Cisco 7000 series and Cisco 7500 series routers support downloadable microcode, which enables you to upgrade microcode versions by downloading new microcode images, storing them in Flash memory, and instructing the system to load an image from Flash instead of the default ROM image. You can store multiple images for an interface type and instruct the system to load any one of them or the default ROM image with a configuration command. All interfaces of the same type (all MIPs, all FIPs, and so on) will load the same microcode image, from either the default ROM image or from a single image stored in Flash.
Although multiple microcode versions for a specific interface type can be stored concurrently in Flash, only one image can load at startup. The show controller cbus command displays the currently loaded and running microcode version for each interface processor. The show configuration command displays the current system instructions for loading microcode at startup. For a complete description of microcode and downloading procedures, refer to the section "Upgrading Microcode" on page 34.
For T1, two standard serial cables, null-modem and straight-through, are available from Cisco Systems and other vendors for use with the MIP. The MIP T1 interface cables are used to connect your router to external CSUs. The MIP T1 interface cables have two male 15-pin DB connectors at each end to connect the MIP with the external CSU. Figure 2 shows the MIP interface cable, connectors, and pinouts. Table 1 lists the signal pinout for the null-modem cable, and Table 2 lists the signal pinout for the straight-through cable.

For E1, four serial cables are available from Cisco Systems for use with the MIP. All three have DB-15 connectors on the MIP end and either BNC, DB-15, Twinax, or RJ-48 connectors on the network end. Figure 3, Figure 4, Figure 5, and Figure 6 show the E1 interface cables (respectively). Table 3 lists the cable pinouts.

Before you begin the installation, review the guidelines in this section to assure proper system operation and to avoid injuring yourself or damaging the equipment. This section also provides a list of parts and tools you will need to perform the installation.
For the online insertion and removal (OIR) feature to operate properly with your MIP, you need specific MIP hardware: MIP Hardware Version 73-0903-08, Board Revision A0. In addition to this MIP hardware requirement, your 7000 family router requires Cisco Internetwork Operating System (Cisco IOS) Release 11.0(6), or later, or Release 11.1(3) or later.
Use the show version (or show hardware) command to verify that your system is running the minimum required Cisco IOS image for OIR functionality with the MIP. Following is sample output of the show version command from a system with Cisco IOS Release 11.0(6):

To determine the hardware versions and revisions of MIPs currently installed in your router, you do not need to remove and examine the MIPs; however, you do need to know in which interface processor slots MIPs are installed.
Use the show interfaces command to show which interface processor slots contain MIPs, then, use the show diag slot command to verify the specific hardware information about each MIP. In the output of the show diag slot command, the Part number and board revision fields indicate the current MIP hardware version and revision installed in a specific slot in your router.
Following is an example of the show diag command for a MIP installed in interface processor slot 3. (Note that the part number field indicates a MIP that is incompatible with OIR.)

The MIP is compatible with any Cisco 7000 series router that is operating with the following software and microcode:
The show version command displays the current hardware configuration of the router, including the system software version that is currently loaded and running. The show controller cbus command lists all CxBus interfaces and includes the currently loaded and running microcode version for each. Use the show version command to display the current system software version, and use the
show controller cbus command to display the microcode version of each interface processor.
In the following example of the show version command, the running system software is Cisco IOS Release 10.0 (or Cisco IOS 10.3 for E1).

In the preceding example, the MIP in slot 2 of the chassis would be displayed as MIP 2.
If the displays indicate that the running system software is earlier than Cisco IOS Release 10.0 for T1 (or Cisco IOS Release 10.3 for E1) or in Cisco 7000 series routers that the running SP (or SSP) microcode is earlier than Version 10.0, 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. The following example shows FIP Microcode Version 1.1 and SP (or SSP) Microcode Version 1.2 stored in Flash:

If the preceding displays indicate that the required system software and microcode are not available, contact a customer service representative for upgrade information. (See the section "Upgrading Microcode" on page 34 for more information.)
This section lists safety guidelines you should follow when working with any equipment that connects to electrical power or telephone wiring.
Follow these basic guidelines when working with any electrical equipment:
Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. The MIP comprises a printed circuit board that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding, connectors, and a handle are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap whenever handling the MIP. Handle the carriers by the handles and the carrier edges only; never touch the boards or connector pins.
Following are guidelines for preventing ESD damage:
 | Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms. |
Online insertion and removal (OIR) allows you to remove and replace interface processors while the system is operating; you do not need to notify the software or shut down the system power.
This section describes mechanical functions of system components, emphasizes the importance of following correct procedures to avoid unnecessary board failures, and is for background only; specific MIP procedures follow in the section "Installing the MIP" on page 20.
Each interface processor contains a receptacle with which it connects to the system backplane. Each backplane connector comprises a set of tiered pins, in three lengths. The pins send specific signals to the system as they make or break contact with the card.
The system assesses the signals it receives and the order in which it receives them to determine what event is occurring and what task it needs to perform, such as reinitializing new interfaces or shutting down removed ones.
For example, when inserting an interface processor, the longest pins make contact with the backplane first, and the shortest pins make contact last. The system recognizes the signals and the sequence in which it receives them. The system expects to receive signals from the individual pins in this logical sequence, and the ejector levers help to ensure that the pins mate in this sequence.
When you remove or insert an interface processor, the backplane pins send signals to notify the system, which then performs as follows:
The system brings on line only interfaces that match the current configuration and were previously configured as up; all others require that you configure them with the configure command. OIR functionality enables you to add, remove, or replace interface processors 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 insert a new interface processor, the system runs a diagnostic test on the new interfaces and compares them to the existing configuration. If this initial diagnostic test fails, the system remains off line for another 15 seconds while it performs a second set of diagnostic tests to determine whether or not the interface processor is faulty and if normal system operation is possible. If the second diagnostic test passes, which indicates that the system is operating normally and the new interface processor is faulty, the system resumes normal operation but leaves the new interfaces disabled.
| Caution While the MIP supports OIR, the system can indicate a hardware failure if you do not follow proper procedures. |
The function of the ejector levers (see Figure 7) is to align and seat the card connectors in the backplane. Failure to use the ejector levers and insert the interface processor properly can disrupt the order in which the pins make contact with the backplane. Follow the MIP installation and removal instructions carefully, and review the following examples of incorrect insertion practices and results:
It is also important to use the ejector levers when removing an interface processor to ensure that the board connector pins disconnect from the backplane in the logical sequence expected by the system. Any processor module that is only partially connected to the backplane can hang the bus. Detailed steps for correctly performing OIR are included with the following procedures for installing and removing the MIP.
You need the following tools and parts to install or upgrade the MIP. If you need additional equipment, contact your service representative for ordering information.
The MIP operates in the Cisco 7000 series routers. The Cisco 7000 series consists of the Cisco 7000 and Cisco 7010 routers.
Figure 8 shows the interface processor end of the Cisco 7000 model, which provides access to the seven processor slots and the removable power supplies. When facing the interface processor end of the chassis, the RP and SP (or SSP) slot are on the far right. The five interface processor slots are numbered 0 to 4 from left to right and support any combination of network interface processors.
Figure 9 shows the interface processor end of the Cisco 7010 model, which provides access to the five processor slots and the removable power supplies. When facing the interface processor end of the chassis, the RP and SP (or SSP) slots are at the top. The three interface processor slots are numbered from the bottom up, beginning with slot 0 (the bottom slot) through 2 (the center slot).
The MIP operates in the Cisco 7500 series routers. The Cisco 7500 series consists of three router models: the Cisco 7505, the Cisco 7507, and the Cisco 7513. All three models provide high reliability, availability, serviceability, and performance. The three systems support multiprotocol, multimedia routing, and bridging with a wide variety of protocols and any combination of Ethernet, Fast Ethernet, Token Ring, Fiber Distributed Data Interface (FDDI), serial, multichannel, channel attachment, and High-Speed Serial Interface (HSSI) media. Network interfaces reside on modular interface processors, which provide a direct connection between the high-speed, 1.067-gigabits-per-second (Gbps) Cisco Extended Bus (CyBus) and the external networks.
Figure 10 shows the rear of the five-slot Cisco 7505 router. In the Cisco 7505, one slot (4) is reserved for the Route Switch Processor (RSP1), which contains the system processor and performs packet switching functions. Slots 0 through 3 are for interface processors.
Figure 11 shows the rear of the seven-slot Cisco 7507 router. In the Cisco 7507, up to two slots (2 and 3) are reserved for the Route Switch Processor (RSP2), which contains the system processor and performs packet switching functions. Slots 0 and 1, and 4 through 6 are for interface processors.
Figure 12 shows the rear of the Cisco 7513 with two AC-input power supplies installed. Two slots (6 and 7) are reserved for the second generation Route Switch Processor (RSP2), which contains the system processor and performs packet switching functions. Slots 0 through 5, and 8 through 12 are for interface processors.
The following sections describe the procedures for removing or installing the MIP. The OIR feature allows you to install and remove the MIP without turning off system power. Refer to the section "Online Insertion and RemovalAn Overview" on page 11 for a complete description of OIR.
| Caution To avoid erroneous failure messages, remove or insert only one interface processor at a time. Also, after inserting or removing an interface processor, allow at least 15 seconds before removing or inserting another interface processor so that the system can reinitialize and note the current configuration of all interfaces. |
If you are replacing a failed MIP, remove the existing board first, then replace the new MIP in the same slot. Figure 13 shows proper handling of an interface processor during installation.
Figure 13 shows proper handling of an interface processor for installation in the Cisco 7000, Cisco 7507, and Cisco 7513 models. The processor slots are oriented horizontally in the Cisco 7010 and Cisco 7505, and vertically in the Cisco 7000, Cisco 7507, and Cisco 7513.
To remove the MIP, follow these steps:
Step 1 Disconnect the MIP interface cables from the MIP ports.
Step 2 Loosen the captive installation screws at the top and bottom of the MIP. (See Figure 7a.)
| Caution Always use the ejector levers to remove or install the MIP. Failure to do so can cause erroneous system error messages, indicating a board failure. |
Step 3 Place your thumbs on the upper and lower ejector levers and simultaneously push the top ejector lever up and the bottom ejector lever down (in the opposite direction from that shown in Figure 7c) to release the MIP from the backplane connector.
Step 4 Grasp the MIP handle with one hand and place your other hand under the carrier to guide the MIP out of the slot. (See Figure 13.) Avoid touching the board or any connector pins.
Step 5 Carefully pull the MIP straight out of the slot, keeping your other hand under the carrier to guide it. (See Figure 13.) Keep the MIP parallel to the backplane.
Step 6 Place the removed MIP on an antistatic mat or foam pad, or place it in an antistatic bag if you will return it to the factory.
Step 7 If the interface processor slot is to remain empty, install an interface processor filler
(MAS-7000BLANK=) to keep dust out of the chassis and to maintain proper airflow through the interface processor compartment.
The MIP slides into any available interface processor slot and connects directly to the backplane. The backplane slots are keyed so that the MIP can be installed only in an interface processor slot. (See Figure 8 or Figure 9.) Interface processor fillers, which are blank interface processor carriers, occupy empty slots to maintain consistent air flow through the interface processor compartment. If you are installing a new MIP, you will have to first remove the interface processor filler from the available interface processor slot. Figure 7 shows the functional details of inserting an interface processor and using the ejector levers. Figure 13 shows proper handling of an interface processor during installation.
| Caution Remove or insert only one interface processor at a time. Allow at least 15 seconds for the system to complete the preceding tasks before removing or inserting another interface processor. Disrupting the sequence before the system completes its verification can cause the system to interpret hardware failures. |
Follow these steps to install the MIP:
Step 1 Ensure that a console terminal is connected to the RP (or RSP) Console port and that the console is turned on.
Step 2 Choose an available interface processor slot for the MIP (see Figure 8, Figure 9, Figure 10, Figure 11, or Figure 12), and ensure that the MIP interface cable is of a sufficient length to connect the MIP with the CSU.
Step 3 Interface processors and interface processor fillers are secured with two captive installation screws. (See Figure 7a.) Use a flat-blade screwdriver to loosen the captive installation screws and remove the interface processor filler (or the existing MIP) from the slot. If you remove the MIP, immediately place it into an antistatic bag to prevent damage from electrostatic discharge.
Step 4 Hold the MIP handle with one hand, and place your other hand under the carrier to support the MIP and guide it into the slot. (See Figure 13.) Avoid touching the card or any connector pins.
| Caution To prevent ESD damage, handle interface processors by the handles and carrier edges only. |
Step 5 Place the back of the MIP in the slot and align the notch on the bottom of the carrier with the groove in the slot. (See Figure 7a.)
Step 6 While keeping the MIP parallel to the backplane, carefully slide the MIP into the slot until the back of the faceplate makes contact with the ejector levers, then stop. (See Figure 7b.)
| Caution Always use the ejector levers when installing or removing processor modules. A module that is partially seated in the backplane will cause the system to hang and subsequently crash. |
Step 7 Using the thumb and forefinger of each hand to pinch each ejector lever, simultaneously push the top ejector lever down and the bottom ejector lever up until both are parallel to the faceplate. (See Figure 7c.)
Step 8 Tighten the captive screws on the top and bottom of the interface processor faceplate to prevent the interface processor from becoming partially dislodged from the backplane and ensure proper EMI shielding. (These screws must be tightened to meet EMI specifications.)
| Caution Always tighten the captive installation screws on interface processors. These screws prevent accidental removal and provide proper grounding for the system. |
Step 9 Attach the MIP network interface cable between the MIP interface ports and to the DSU.
Step 10 Proceed to the following section to check the installation.
After you install the MIP, verify the installation by observing the LED states and the console display. When the system finishes reinitializing all interfaces, the enabled LED on the MIP and on all interface processors should be lit. The console screen will also display a message as the system discovers each interface during its reinitialization.
When you remove and replace CxBus interface processors, the system provides status messages on the console screen. The messages are for information only. The following sample display shows the events logged by the system as the MIP was removed from slot 4; the system then reinitialized the remaining interface processors and marked as down the MIP that was removed from slot 4. When the MIP was reinserted, the system marked the interfaces as down again because the MIP interfaces were not shut down before the MIP was removed.
Router# %OIR-6-REMCARD: Card removed from slot 4, interfaces disabled %LINK-5-CHANGED: Interfaces MIP1/0, changed to administratively down Router# %OIR-6-INSCARD: Card inserted in slot 4, interfaces administratively shut down Router# Router#
When a new MIP is inserted or when the MIP is moved to a new slot, the system recognizes the new MIP controllers, but leaves them in a down state until you configure them and change the state to up with the configure command.
The following example display shows the events logged by the system as a new MIP is inserted in slot 4:
Router# OIR-6-REMCARD: Card removed from slot 4, interface disabled Link-5-CHANGED: Interface MIPl/0, changed state to administratively down Router# %OIR-6-INSCARD: Card inserted in slot 4, interfaces administratively shut down Router#
Verify that the MIP is installed correctly as follows:
Step 1 While the system reinitializes each controller, observe the console display messages and verify that the system discovers the MIP as follows:
Step 2 When the reinitialization is complete, verify that the enabled LED on the MIP turns on and remains on. If it does, proceed to step 5. If it does not, proceed to the next step.
Step 3 If the enabled LED on the MIP fails to go on, suspect that the MIP board connector is not fully seated in the backplane. Loosen the captive installation screws, then firmly push the top ejector lever down while pushing the bottom ejector lever up until both are parallel to the MIP faceplate. Tighten the captive installation screws. After the system reinitializes, the enabled LED on the MIP should go on. If it does, proceed to step 5. If it does not, proceed to the next step.
Step 4 If the enabled LED still fails to go on, remove the MIP and try installing it in another available interface processor slot.
Step 5 If the MIP controller is new, proceed to the section "Configuring the E1 and T1 Interfaces" on page 24 to configure the new controller. (This does not have to be done immediately, but the controller will not be available until you configure it.)
Step 6 If this installation was a replacement MIP, use the show interfaces or show controllers cbus command to verify the status of the MIP controller.
Step 7 When the MIP controller is up, check the activity of the controller with the MIP LEDs, which are shown in Figure 14.
There are three LEDs associated with each MIP port that indicate alarm or loop conditions on that port. (See Figure 1.) The three LEDs above each MIP port indicate the following:
If an error message displays on the console terminal, refer to the System Error Messages publication for error message definitions. If you experience other problems that you are unable to solve, contact a service representative for assistance.
This completes the MIP installation. If you installed a new MIP, you must now configure the new MIP controller, as described in the following section.
If you installed a new MIP or if you want to change the configuration of an existing controller, you must enter the configuration mode. If you replaced the MIP that was previously configured, the system will recognize the new MIP and bring it up in the existing configuration.
After you verify that the new MIP is installed correctly (the enabled LED is on), use the
privileged-level configure command to configure the new MIP controller. Be prepared with the information you will need, such as the following:
Refer to the Router Products Configuration Guide and Router Products Configuration Guide Addendum publications for a summary of the configuration options available and instructions for configuring the MIP controller.
By default, channelized E1 port adapters are set with capacitive coupling between the receive (Rx) shield and chassis ground. This provides direct current (DC) isolation between the chassis and external devices, as stated in the G.703 specification. Jumper J6 controls this function. To make changes, remove the MIP from the chassis, remove the E1 port adapter from the motherboard, place one of the spare jumpers on J6 pins one and two or pins two and three (refer to Table 4), and replace the port adapter on the motherboard. Pin 1 of J6 is designated with a square. (See Figure 15.)
| Jumper | Pins and Impedance | Function | |
|---|---|---|---|
| J6 | 1 and 2 for 120 ohm | Controls capacitive coupling for either 120-ohm or 75-ohm operation. An installed jumper directly connects the Rx shield to chassis ground. | |
 | Warning To prevent problems with the E1 interface and to reduce the potential for injury, jumper J6 should be installed by trained service personnel only. For either impedance option, a jumper installed at J6 bypasses the AC-decoupling capacitor to ground, thereby coupling the interface directly to AC. This is a setting that could pose a risk of severe injury. By default and for safety, J6 has no jumper installed. |
To remove the MIP, in order to set jumper J6, proceed to the section "Removing and Replacing Port Adapters" on page 38.
Before you use the configure command, you must enter the privileged level of the EXEC command interpreter with the enable command. The system will prompt you for a password if one has been set.
The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>). At the console terminal, enter the privileged level as follows:
Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a privileged-level password, as follows:
enable
Step 2 Enter the password (the password is case-sensitive). For security purposes, the password is not displayed.
Step 3 When you enter the correct password, the system displays the privileged-mode system prompt (#) as follows:
Step 4 Proceed to the following section to configure the MIP controller.
Following are instructions for a configuration: enabling a controller and specifying IP routing. You might also need to enter other configuration subcommands, depending on the requirements for your system configuration and the protocols you plan to route on the interface.
The channel-groups must be mapped before the MIP controller can be configured.
For complete descriptions of configuration subcommands and the configuration options available, refer to the Router Products Configuration Guide, Router Products Configuration Guide Addendum, and Router Products Command Reference publications.
Table 5 lists the commands used to map the channel group; the default variable is listed first.
| Commands for T1 | Commands for E1 |
|---|---|
| controller t1 slot/applique | controller e1 slot/applique |
| clock source [line | internal] | Not required for E1 |
| linecode [ami | b8zs] | linecode [hdb3 | ami] |
| framing [sf | esf] | framing [crc4 | no-crc4] |
| loopback [local | remote] | loopback |
| shutdown | shutdown |
| channel-group number timeslots list [speed {56 | 48 | 64}] For speed, 56 is the default. | channel-group number timeslots list [speed {56 | 48 |64}] For speed, 64 is the default. |
Number is the channel-group 0 to 23 for T1 and 0 to 29 for E1.
Timeslots list is a number between 1 to 24 for T1 and 1 to 31 for E1. It conforms to D3/D4 numbering for T1. Timeslots may be entered individually and separated by commas or as a range that is separated by a hyphen (for example, 1-3, 8, 9-18). For E1 and T1, 0 is illegal.
Speed specifies the DSO speed of the channel-group: T1 default is 56 kbps and E1 default is 64 kbps.

The following procedure summarizes how to use the show commands to verify that the new MIP interface is configured correctly:
Step 1 Use the show version command to display the system hardware configuration. Ensure that the list includes the new MIP network interface.
Step 2 Display all of the current CxBus interface processors and their interfaces with the show controllers cbus command. Verify that the new MIP appears in the correct slot.
Step 3 Display the T1 and/or E1 alarm condition with the show controller T1 and/or show controller E1 command.
Step 4 Specify the new interface with the show interfaces serial slot/port:channel-group command and verify that the first line of the display specifies the serial interface with the correct slot, port, and channel group number. Also verify that the interface and line protocol are in the correct state: up or down.
Step 5 Display the protocols configured for the entire system and specific interfaces with the command show protocols. If necessary, return to the configuration mode to add or remove protocol routing on the system or specific interfaces.
Step 6 Display the entire system configuration file with the show configuration command. Verify that the configuration is accurate for the system and each interface.
If the interface is down and you configured it as up, or if the displays indicate that the hardware is not functioning properly, ensure that the network interface is properly connected and terminated. If you still have problems bringing the interface up, contact a customer service representative for assistance.
This completes the configuration procedure for the new MIP interface.
Cisco 7000 series and Cisco 7500 series routers support downloadable microcode, which enables you to upgrade microcode versions without having to physically replace the ROMs on the boards. You can download new microcode versions and store multiple versions in Flash memory, and you can boot from them just as you can with the system software images. System software upgrades might also contain upgraded microcode images, which will load automatically when the new software image is loaded.
You can download microcode to Flash memory by copying the TFTP image of a microcode version to Flash memory. When the microcode image is stored in Flash memory, you can use the microcode reload command to manually load the new microcode file, and the configure command to instruct the system to load the new image automatically at each system boot.
| Caution Before you copy a file to Flash, be sure there is ample space available in Flash memory. Compare the size of the file you wish to copy to the amount of available Flash memory shown. If the space available is less than the space required by the file you wish to copy, the copy process will continue, but the entire file will not be copied into Flash. |
To compare the size of the microcode image and the amount of Flash memory available, you must know the size of the new microcode image. The image size is specified in the README file that is included on the floppy disk with the new image, and in the Upgrading System Software and Microcode in the Cisco 7000 Family Routers publication that is shipped with all microcode upgrades. Note the size of the new image before proceeding to ensure that you have sufficient available Flash memory for the new image.
Follow these steps to copy a microcode version from the TFTP server to Flash memory.
Step 1 To display the total amount of Flash memory present, its location, any files that currently exist in Flash memory and their size, and the amount of Flash memory remaining, use the show flash command. Following is an example of the output that is displayed:
show flash
Step 2 Compare the amount of available Flash memory (last line in the preceding example) to the size of the new microcode image on the floppy disk to ensure that there is sufficient space available. If you attempt to copy in a new image, and the size of the new image exceeds the available space in Flash, only part of the new image will be copied, and the following error message will be displayed:
where xxxx/xxxx is the number of bytes read in/number of bytes available.
Step 3 After you verify that there is sufficient space available in Flash memory for the new image, enter the following command at the privileged-level prompt:
copy tftp flash
Step 4 Enter the IP address of the remote host:
Step 5 Enter the name of the file you want to copy to Flash (mip1-1 in the following example):
mip1-1
Step 6 To confirm that you want the file copied into Flash, press Return.
If the correct file is not shown, enter no at the prompt to return to the system prompt and enter the correct file name.
Step 7 If you do not want Flash erased, enter no at the next prompt. If you accept the default to erase by pressing Return without first typing no, the new image will write over the entire contents of Flash memory, and you will lose all other microcode and system software images stored in Flash.
no
While the file is copied to Flash, output similar to the following is displayed:
Step 8 Use the show flash command to verify that the microcode has been copied to Flash. The output should display the file name of the image you copied to Flash (mip1-1 in the following example):
show flash
4096K bytes of flash memory on embedded flash (in RP1).
Step 9 To ensure that the new microcode is used when you reboot the system, add the appropriate commands to the configuration file. To modify the configuration file, enter the following command:
configure terminal
Step 10 Specify that you are changing the microcode for the MIP (microcode mip), and that it will load from Flash memory (flash). Then add the file name of the new microcode image to be loaded from Flash:
microcode mip flash mip1-1
Step 11 To save the configuration file, press Ctrl-Z.
Step 12 Copy the new configuration to NVRAM, as follows:
copy running-config startup-config
The microcode reload command is automatically added to your running configuration. The new MIP microcode image will load automatically the next time the system boots or reinitializes.
Step 13 To load the new microcode immediately, you can instruct the system to load the new microcode by issuing the microcode reload configuration command (you must be in configuration mode to enter this command):
configure
microcode reload
Immediately after you enter the microcode reload command and press Return, the system reloads all microcode. Configuration mode remains enabled; after the reload is complete, press Ctrl-Z to exit from configuration mode and return to the system prompt.
Step 14 To verify that the MIP is using the correct microcode, issue the show configuration or show controller cbus command. The show controller cbus display indicates the currently loaded and running microcode version for each interface processor.
show configuration
This completes the procedure for downloading microcode to Flash memory.
Port adapters provide the ports for the E1 and T1 interfaces. Each port adapter provides one port. Each MIP is shipped from the factory with one or two port adapters installed. You cannot add ports to an MIP by installing an additional port adapter. Port adapters are not field-replaceable units (FRUs); however, you need to remove an existing E1 port adapter in order to access jumper J6.
Before proceeding, refer to the section "Removing the MIP" on page 20.
| Caution To prevent damaging the MIP and port adapters, remove and install port adapters only when it is necessary. Do not attempt to isolate faults or to troubleshoot MIPs or interfaces by swapping port adapters. The surface-mount circuitry on the port adapters will not tolerate excessive handling. Do not mix T1 and E1 port adapters on the same mother board. |
You need the following tools to complete this procedure:
Port adapters are installed on each MIP at the factory. Each port adapter is anchored to the MIP with one plastic double-row vertical board-to-board (BTB) connector and four Phillips screws that extend through standoffs, into the motherboard. (See Figure 16.) The port adapter is also anchored to the carrier faceplate with two jackscrews and two lock washers.
| Caution The surface-mounted components on the port adapters are extremely susceptible to ESD damage. Keep each port adapter in a separate antistatic bag until you are ready to install it. Always wear an ESD-preventive ground strap and handle boards as little as possible. When you must handle the board, limit contact to the board edges only, avoiding contact between the board and clothing. |
To remove an E1 port adapter from the MIP, refer to Figure 16 and perform the following steps:
Step 1 Ensure that the MIP is resting on an antistatic mat or on antistatic foam. You should still be wearing an ESD-preventive strap.
Step 2 Position the MIP so that it is in the same orientation shown in Figure 16.
Step 3 Locate the E1 port adapter to be removed and use a 3/16-inch nut driver to loosen the two jackscrews, one on either side of the cable connector. (See Figure 16.)
Step 4 Remove the jackscrews and washers and put them aside.
Step 5 Use a number 1 Phillips screwdriver to loosen and remove the four standoff screws. (See Figure 16.) The port adapter is now held in place only by the plastic BTB connector.
Step 6 While avoiding contact with any traces or components on the board, insert your thumb and forefinger under the extension behind the BTB connector and gently lift the adapter upward to dislodge it from the MIP connector. If the port adapter resists, rock it very slightly from side to side until it pulls free of the MIP connector.
| Caution To prevent damage to the MIP, do not pry the port adapter out with a screwdriver or any other tool. In particular, do not use the board stiffener for leverage. |
Step 7 When the port adapter is completely disconnected from the MIP connector, tilt the back of the port adapter up at about a 70-degree angle from vertical and slowly pull it up and out (using the orientation shown in Figure 16) and away from the faceplate. The MIP cable connector will pull out of the cutout in the faceplate.
Step 8 To reconfigure jumpers on the E1 port adapter, refer to the section "Configuring Jumper J6 on the E1 Port Adapter" on page 25. After you have set the jumpers, proceed to the section "Replacing a Port Adapter."
| Caution To prevent overheating chassis components, do not reinstall the MIP in the chassis unless all port adapters are in place. The empty port will allow cooling air to escape freely through the cutouts in the faceplate, which could misdirect the airflow inside the chassis and allow components on other boards to overheat. |
If necessary, refer to the previous section to remove an E1 port adapter from the MIP. Refer to Figure 17 while you perform the following steps:
Step 1 Ensure that the MIP is resting on an antistatic mat or on antistatic foam and position it with the same orientation as that shown in Figure 17. You should still be wearing an ESD-preventive ground strap.
Step 2 Handle the port adapter by the board edges only.
Step 3 Position the port adapter so that it is in the orientation shown in Figure 17: at about a 70-degree angle from vertical, component-side down, standoffs on the underside, and the external interface cable connector facing the inside of the carrier faceplate.
Step 4 As shown in Figure 17, partially insert the cable connector through the back of the cutout in the carrier faceplate. Do not force the cable connector through the cutout until the standoffs and BTB connector are aligned.
Step 5 With the cable connector partially inserted into the faceplate cutout, slowly lower the back (opposite) side of the port adapter. Continue to ease the cable connector through the cutout until the BTB connector and the MIP and port adapter meet and the standoffs on the MIP are aligned with the standoff holes in port adapter. Shift the port adapter until the cable connector is fully inserted through the cutouts and the standoffs are aligned with the standoff holes. (See Figure 17.)
Step 6 Place your fingers over the BTB connector and firmly (but gently) press down until the BTB connector mates with the MIP connector. If the connector resists, do not force it. Shift the port adapter around until the connectors mate properly.
Step 7 Insert the four long Phillips screws through the four port adapter holes and finger-tighten them. These screws extend through the standoffs and the MIP board and thread into the metal carrier.
Step 8 Install a lockwasher on each of the two jackscrews.
Step 9 Insert the two jackscrews through the front of the carrier faceplate and into the holes on either side of the cable connector.
Step 10 When all screws and connectors are aligned properly, use a Phillips screwdriver to tighten the four standoff screws and a 3/16-inch nut driver to tighten the two jackscrews. Do not overtighten any of these screws.
Step 11 Follow the steps in the section "Installing the MIP" on page 21 to reinstall the MIP in the chassis.
Step 12 Reconnect the network interface cables or other connection equipment to the MIP interface ports.
| Caution To prevent potential EMI and overheating problems, do not replace the MIP in the chassis unless all port adapters are installed. An empty port violates the EMI integrity of the system, and also allows cooling air to escape freely through the cutouts in the carrier faceplate, which could misdirect the airflow inside the chassis and allow components on other boards to overheat. |
When you insert the new MIP, the console terminal will display several lines of status information about OIR as it reinitializes the interfaces. Change the state of the interfaces to up and verify that the configuration matches that of the interfaces you replaced.
Use the configure command or the setup command facility to configure the new interfaces. You do not have to do this immediately, but the interfaces will not be available until you configure them and bring them up.
After you configure the interfaces, use the show controller cbus, show controller T1, show controller E1 commands to display the status of the new interface. For brief descriptions of commands, refer to "Using Show Commands to Verify the MIP Status" on page 33.
For complete command descriptions and instructions, refer to the appropriate software publications.
This completes the port adapter replacement procedure.
