Using Interface Processors

This chapter describes essential procedures and guidelines for using all interface processors; it includes the following sections:

What Is an Interface Processor?

An interface processor is a printed circuit board attached to a metal carrier with a handle on the front. Interface processors provide the electrical interface connections between the system bus inside the Cisco 7000 series and Cisco 7500 series routers and your network. Interface processors provide the following electrical interface media: Asynchronous Transfer Mode (ATM), Basic Rate Interface (BRI), channel attachment, channelized E1, T1, and T3, Ethernet, Fast Ethernet, Fiber Distributed Data Interface (FDDI), High-Speed Serial Interface (HSSI), multichannel, Primary Rate Interface (PRI), Packet over OC-3, synchronous serial, and Token Ring. All interface processors are available as spare parts.

Interface processors are installed in the interface processor slots of the Cisco 7000 series and Cisco 7500 series routers. Interface processors are keyed so they cannot be installed in noninterface processor slots. Noninterface processor slots are slots 5 and 6 in the Cisco 7000; slots 3 and 4 in the Cisco 7010; slot 4 in the Cisco 7505; slots 2 and 3 in the Cisco 7507; and slots 6 and 7 in the Cisco 7513.

These noninterface processor slots are reserved for the Router Switch Processor (RSP1, RSP2, or RSP4), which are the main system processors for the Cisco 7000 series and Cisco 7500 series routers.

Interface Processor Slot Locations

The interface processor slots in the Cisco 7000 series and Cisco 7500 series routers are as follows:

Cisco 7000--slots 0 through 4 (See Figure 1-1.)
Cisco 7010--slots 0 through 2 (See Figure 1-2.)
Cisco 7505--slots 0 through 3 (See Figure 1-3.)
Cisco 7507--slots 0 and 1, and slots 4 through 6 (See Figure 1-4.)
Cisco 7513--slots 0 through 5, and slots 8 through 12 (See Figure 1-5.)

Note The interface processor slots are oriented horizontally in the Cisco 7010 and Cisco 7505, and vertically in the Cisco 7000, Cisco 7507, and Cisco 7513.

Safety Guidelines

This section lists safety guidelines you should follow when working with any equipment that connects to electrical power or telephone wiring.

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working.
Disconnect all power and external cables before moving a chassis.
Do not work alone if potentially hazardous conditions exist.
Never assume that power is disconnected from a circuit; always check.
Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

Telephone Wiring Guidelines

Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:

Never install telephone wiring during a lightning storm.
Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. 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 an interface processor. 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:

Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact; connect the equipment end of the strap to a captive installation screw on an installed power supply.
When installing an interface processor, use the ejector levers to properly seat the bus connectors in the backplane, then tighten both captive installation screws. These screws prevent accidental removal, provide proper grounding for the system, and help ensure that the bus connectors are seated in the backplane.
When removing an interface processor, use the handle to pull the interface processor out slowly while keeping your other hand underneath the carrier to guide it straight out of the slot.
Handle carriers by the handles and carrier edges only; avoid touching the board or connectors.
Place a removed interface processor board-side-up on an antistatic surface or in a static shielding bag. If you plan to return the component to the factory, immediately place it in a static shielding bag.
Avoid contact between the interface processor and clothing. The wrist strap only protects the board from ESD voltages on the body; ESD voltages on clothing can still cause damage.
Never attempt to remove an interface processor printed circuit board from the metal interface processor carrier.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms.

Guidelines for Interface Processor Removal and Installation

This section describes the mechanical functions of system components and emphasizes the importance of following correct procedures to avoid unnecessary board failures. Specific procedures follow these general background and safety guidelines in the section "Interface Processor Replacement Procedures" on page 1-11.

You can remove and replace interface processors while the system is operating; you do not need to notify the software or reset the system power. This 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.

After an interface processor is reinstalled, 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. For information on configuring interfaces, refer to the chapter(s) specific to your interface processor(s).

Caution The system can indicate a hardware failure if you do not follow proper procedures. 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.

Note We recommend that you install interface processors starting with the slots closest to the RSPs and work out concentrically from there. This will help to ensure that rejection of electromagnetic interference (EMI) is maintained.

All interface processors have ejector levers that allow you to firmly seat an interface processor in the interface processor slot (see Figure 1-7). The function of the ejector levers 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 installation and removal instructions carefully, and review the following examples of incorrect insertion practices and results:

Using the handle to force the interface processor all the way into the slot can pop the ejector levers out of their springs. If you then try to use the ejector levers to seat the interface processor, the first layer of pins (which are already mated to the backplane) can disconnect and then remate with the backplane, which the system interprets as a board failure.
Using the handle to force or slam the interface processor all the way into the slot can also damage the pins on the board connectors if they are not aligned properly with the backplane.
When using the handle (rather than the ejector levers) to seat the interface processor in the backplane, you might need to pull the interface processor back out and push it in again to align it properly.

: Even if the connector pins are not damaged, the pins mating with and disconnecting from the backplane will cause the system to interpret a board failure. Using the ejector levers ensures that the board connector mates with the backplane in one continuous movement.

Using the handle to insert or remove an interface processor, or failing to push the ejector levers to the full parallel position, can leave some (not all) of the connector pins mated to the backplane, a state that will hang the system. Using the ejector levers and making sure that they are pushed fully into position ensures that all three layers of pins are mated with (or free from) the backplane.

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 (interface processor or RSP) that is only partially connected to the backplane can hang the bus. (Detailed steps for correctly installing and removing an interface processor follow in the section "Interface Processor Replacement Procedures.")

Interface Processor Replacement Procedures

Typically, your interface processors arrive preinstalled in your Cisco 7000 series and Cisco 7500 series routers (with the exception of the Cisco 7513); however, occasionally you might have to remove and replace interface processors for maintenance.

The following sections describe the procedures for removing or installing an interface processor. (Refer the section "Guidelines for Interface Processor Removal and Installation" before removing an interface processor while power to the system is on.)

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.

Note If you install or remove other interface processors in a Cisco 7000 series or Cisco 7500 series router with a CT3IP installed, you might have to reboot the system after the removal and replacement of that interface processor. (In general, and to prevent system problems, we recommend you follow the procedures described in this section and the guidelines described in the preceding section "Guidelines for Interface Processor Removal and Installation.")

Tools Required

Following are the tools required for interface processor replacement:

Number 1 Phillips or 3/16-inch flat-blade screwdriver for the captive installation screws on the interface processors
Antistatic mat or foam pad, or an antistatic bag, on or in which to place removed interface processors
Your own ESD grounding strap or the disposable ESD strap included with your system

Removing an Interface Processor

If you are replacing a failed interface processor, remove the existing board first, then install the new interface processor in the same slot.

Note In Cisco 7507 or Cisco 7513 systems, online insertion and removal of any interface processor in either CyBus might cause the slave RSP2 to reboot with ao bus error or a processor memory parity error. The master RSP will recover from this event and issue a "cBus Complex Restart" message. Cisco 7507 and Cisco 7513 systems that are configured with an RSP4 as the system slave are not affected and will not experience this problem.

If you have a Cisco 7507 or a Cisco 7513 with an RSP2 configured as the system slave, we strongly recommend that you use the following procedure to remove and replace an interface processor:

Step 1 Remove the slave RSP2.

Step 2 Wait 15 seconds.

Step 3 Remove and replace the interface processor using the procedures in this publication.

Step 4 Wait 15 seconds.

Step 5 Reinsert the slave RSP2.

Figure 1-6 shows proper handling of an interface processor during installation.

Before you remove an interface processor that you will not replace, or replace an interface processor component, we recommend you shut down (disable) the interfaces to prevent anomalies when you reinstall the new or reconfigured interface processor. When you shut down an interface, it is designated administratively down in the show command displays. (For the interface shutdown procedure, refer to the section "Shutting Down an Interface" on page 1-19.)

Figure 1-6: Handling Interface Processors during Installation (Horizontal Orientation Shown)

Use the following procedure to remove an interface processor:

Step 1 Disconnect the interface processor's cables from the interface ports.

Step 2 Loosen the captive installation screws at the ends of the interface processor faceplate. (See Figure 1-7a.)

Caution Always use the ejector levers to remove or install an interface processor. 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 1-7c) to release an interface processor from the backplane connector.

Step 4 Grasp the interface processor handle with one hand and place your other hand under the carrier to guide the interface processor out of the slot. (See Figure 1-6.) Avoid touching the board or any connector pins.

Step 5 Carefully pull the interface processor straight out of the slot, keeping one hand under the carrier to guide it. (See Figure 1-6.) Keep the interface processor parallel to the backplane.

Step 6 Place the removed interface processor 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.

Installing an Interface Processor

Interface processors slide into any available interface processor slot and connect directly to the backplane. The backplane slots are keyed so that interface processors can be installed only in an interface processor slots. Interface processor fillers, which are blank interface processor carriers, occupy empty slots to maintain consistent air flow through the interface processor compartment.

If you install a new interface processor, you have to first remove the interface processor filler from the available interface processor slot. Figure 1-7 shows functional details of inserting an interface processor and using ejector levers. (Figure 1-6 shows proper handling of an interface processor during installation.)

Note There are no restrictions on slot locations or interface processor sequence, and you can install the interface processor in any available interface processor slot; however, in the Cisco 7507 and Cisco 7513, we recommend that you install interface processors starting with the slots closest to the RSPs and work out concentrically from there. This will help prevent electromagnetic interference (EMI).

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 this as a hardware failure.

Use the following procedure to install an interface processor:

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 interface processor, and ensure that the interface processor's cable is of a sufficient length to connect the interface processor with any external equipment. We recommend that you install interface processors starting with the slots closest to the RSPs and work out concentrically from there. This will help prevent EMI.

Step 3 Interface processors and interface processor fillers are secured with two captive installation screws. (See Figure 1-7a.) Use a flat-blade screwdriver to loosen the captive installation screws and remove the interface processor filler (or the existing interface processor) from the slot. If you remove an interface processor, immediately place it in an antistatic bag to prevent damage from electrostatic discharge.

Figure 1-7: Location of Ejector Levers and Captive Installation Screws

Step 4 Hold the interface processor handle with one hand, and place your other hand under the carrier to support the interface processor (see Figure 1-6); guide the carrier into the slot. 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 interface processor in the slot and align the notch on the bottom of the carrier with the groove in the slot. (See Figure 1-7a.)

Step 6 While keeping the interface processor parallel to the backplane, carefully slide the interface processor into the slot until the back of the faceplate makes contact with the ejector levers, then stop. (See Figure 1-7b.)

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 1-7c.)

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 To ensure adequate space for additional interface processors, always tighten the captive installation screws on each newly installed interface processor before you insert any additional interface processors. These screws also prevent accidental removal, and provide proper grounding and EMI shielding for the system.

Using the EXEC Command Interpreter

After you have connected your interface processors' interface cables, but before you can use the interfaces, you must configure them using the configure command. However, before you can 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; this applies to all interface processors. The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>).

At the console terminal, use the following procedure to enter the privileged level:

Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a privileged-level password as follows:

Router> enable

Password:

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:

Router#

Step 4 Exit privileged level and return to user level by entering disable at the prompt as follows:

Router# disable

Router>

After you enter the privileged level of the EXEC command interpreter, you need to enter configuration mode and specify that the console terminal will be the source of the configuration subcommands you need to use, as follows:

Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z. 
Router(config)#

To exit configuration mode, press Ctrl-Z (hold down the Control key while you press Z).

To configure your interfaces, follow the specific configuration steps that are provided in the chapter appropriate to your interface processor.

Shutting Down an Interface

Before removing an interface processor that you will not replace, or replacing an interface processor component, we recommend you shut down (disable) the interfaces to prevent anomalies when you reinstall the new or reconfigured interface processor. When you shut down an interface, it is designated administratively down in the show command displays.

Use the following standard procedure to shut down any interface:

Step 1 Enter the privileged level of the EXEC command interpreter. (Refer to the section "Using the EXEC Command Interpreter" for instructions.)

Step 2 At the privileged-level prompt, enter configuration mode and specify that the console terminal will be the source of configuration subcommands as follows:

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#

Step 3 Specify the slot/port address of the first interface that you want to shut down by entering the subcommand interface type slot/port, where the type is serial, ethernet, and so forth, and slot/port is the interface processor slot followed by the port number to be shut down.

Following is an example for the first interface port on an interface processor in interface processor slot 0:

Router(config)# interface type 0/0

Step 4 Enter the shutdown command as follows:

Router(config-if)# shutdown

Step 5 To shut down additional interfaces, enter the slot/port address of each additional interface followed by the shutdown command. When you have entered all the interfaces to be shut down, press Ctrl-Z (hold down the Control key while you press Z) to exit configuration mode and return to the EXEC command interpreter prompt, as follows:

Router(config-if)# interface type 0/1

Router(config-if)# shutdown

Router(config-if)# interface type 0/2

Router(config-if)# shutdown

Ctrl-Z

Step 6 Write the new configuration to nonvolatile random access memory (NVRAM) as follows:

Router# copy running-config startup-config

[OK]

Router#

The system displays an OK message when the configuration has been stored.

Step 7 To verify that new interfaces are now in the correct state (shut down), use the show interface type slot/port command to display the specific interface, or use the show interfaces command, without variables, to display the status of all interfaces in the system.

Router# show interface type 0/0

(additional displayed text omitted from this example)

Type1/0 is administratively down, line protocol is down

(additional displayed text omitted from this example)

Step 8 To reenable the interfaces, repeat the previous steps but use the no shutdown command (in Step 4), then write the new configuration to NVRAM as follows:

Router# copy running-config startup-config

[OK]

Router# show interface type 0/0

(additional displayed text omitted from this example)

Type0/0 is up, line protocol is up

(additional displayed text omitted from this example)

This completes the procedure for shutting down an interface.

Perform the maintenance procedures you require, then reenable the interface using the no shutdown command. To reconfigure your interface, follow the specific configuration steps that are provided in the chapter appropriate to your interface processor.

Upgrading Interface Processor Microcode Images

Cisco 7000 series and Cisco 7500 series routers support downloadable microcode. Each interface processor requires a specific microcode image to operate, and each router is shipped with Cisco IOS software images and interface processor microcode images installed. Microcode images are bundled with the Cisco IOS software image that shipped with your router. We strongly recommend that you use these bundled microcode images.

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 Trivial File Transfer Protocol (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 memory, be sure there is ample space available in Flash memory. Compare the size of the file you want to copy to the amount of available Flash memory shown. If the space available is less than the space required by the file you want to copy, the copy process will continue, but the entire file will not be copied into Flash memory.

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. Note the size of the new image before proceeding, to ensure that you have sufficient available Flash memory for the new image.

Note Some interface processors might have special considerations regarding microcode upgrades; refer to the appropriate chapter for your interface processor and follow any microcode upgrade procedures that might be included.

Use the following procedure to copy a microcode version from a 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:

Router# show flash

4096K bytes of flash memory on embedded flash (in RSP1).

file offset length name

(additional displayed text omitted from this example)

[4085336/4194304 bytes free]

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:

buffer overflow - xxxx/xxxx

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:

Router# copy tftp flash

Step 4 Enter the IP address of the remote host:

IP address or name of remote host [255.255.255.255]? 1.1.1.106

Step 5 Enter the name of the file you want to copy to Flash (vip221-40 is used in the following examples):

Name of file to copy? vip221-40

Step 6 To confirm that you want the file copied into Flash, press Return.

Copy vip221-40 from 1.1.1.106 into flash memory? [confirm]

If the correct file is not shown, enter no at the prompt to return to the system prompt; then 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.

Erase flash before writing? [confirm] no

While the file is copied to Flash, output similar to the following is displayed:

Loading from 1.1.1.106: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[OK - 108966/4194304 bytes] Verifying via checksum... Flash verification successful. Length = 53364, checksum = 0x0000

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 (vip221-40 in the following example):

Router# show flash 4096K bytes of flash memory on embedded flash (in RSP1).

file offset length name 1 0xD0D4 53364 vip221-40 [4085336/4194304 bytes free]

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:

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#

Step 10 Specify that you are changing the microcode for the interface processor (microcode vip2 for example), and that it will load from Flash memory (bootflash:, slot0:, or slot1:); then add the filename of the new microcode image to be loaded from Flash. Following is an example of a microcode image that will load from the Flash memory card in PCMCIA slot 0:

Router(config)# microcode vip2 slot0:vip221-40

Step 11 To exit Configuration mode, press Ctrl-Z.

Step 12 Copy (save) the new configuration to NVRAM as follows:

Router# copy running-config startup-config

[OK]

Router#

The microcode reload command is automatically added to your running configuration. The new interface processor 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):

Router# configure

Router(config)# 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 interface processor is using the correct microcode, issue the show running-config, show startup-config, or show controller cbus commands. The show controller cbus display also indicates the currently loaded and running microcode version for each interface processor.

Router# show running-config

This completes the procedure for downloading microcode to Flash memory. For more complete information on the use of Flash memory, refer to the hardware installation and configuration documentation that shipped with your router.
