This document describes the Versatile Interface Processor (VIP6-80), an option available for use with the Cisco 7500 series and the Cisco 7000 series routers using the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI). The VIP6-80 improves high-performance switching over previous generation VIPs.
The VIP6-80 supports online insertion and removal (OIR), a feature that allows you to remove and replace a VIP6-80 without first shutting down the system. However, the VIP6-80 does not support OIR of port adapters (PAs). The VIP6-80 must be removed before removing or installing the port adapter.
The VIP6-80 also supports Single Line Card Reload, a feature that reloads a failed line card on the network backplane without reloading other line cards. Refer to the "Single Line Card Reload" section for more information.
The VIP6-80 supports any combination of LAN and WAN PAs, including Fast Ethernet, T1/E1, High-Speed Serial Interface (HSSI), T3/E3, T3/E3 ATM, multichannel T1/E1, multichannel T3/E3, OC-3 ATM, Packet over SONET (POS), and OC-12 ATM. For a list of supported port adapters, refer to the "Port Adapter Slots" section.
This guide includes the following sections:
Your router and the Cisco IOS software running on it contain extensive features and functionality, which are documented in the following resources:
For configuration information and support, refer to the modular configuration and modular command reference publications in the Cisco IOS software configuration documentation set that corresponds to the software release installed on your Cisco hardware.

The topics discussed in this section are as follows:
The VIP6-80 is available for use as an option with the Cisco 7505, Cisco 7507, Cisco 7507-MX, Cisco 7513, Cisco 7513-MX, Cisco 7576, and the Cisco 7000 series routers. The VIP6-80 is not currently available as an upgrade to an existing VIP.
The VIP6-80 has a main processor and memory. When distributed switching is enabled on the router, the VIP6-80 can make packet switching decisions to help reduce the load on the Route Switch Processor (RSP). Interfaces located on port adapters that fit into the VIP6-80 connect the router to the external network. Either one dual-width or two single-width PAs can be used on the VIP6-80. See the "Port Adapter Slots" section for more information.
The VIP6-80 supports OIR. VIP6-80 PAs do not support OIR, so you must first remove the VIP6-80 before removing or installing the PAs.
The VIP6-80 also supports Single Line Card Reload (SLCR), a feature which speeds recovery of a failed router by reloading a failed line card without reloading other line cards on the network backplane. For more information, refer to "Single Line Card Reload" section.
Table 1 outlines features of the VIP6-80 model.

The VIP6-80 has LEDs; however, they are not be visible once the VIP is installed in the Cisco 7500 or the Cisco 7000 router. The port adapters that fit into the VIP do have visible LEDs. Refer to the Installation and Configuration Guide for your specific port adapter for more information.
There are no user-configurable jumpers on the VIP6-80.
The Cisco 7500 and Cisco 7000 series routers support downloadable microcode, which enables you to upgrade microcode versions by downloading new microcode images, storing them in system Flash memory, and instructing the system to load its image from Flash memory. You can store multiple images for an interface type, such as the VIP6-80, and, with a configuration command, instruct the system to load any one of them or the default microcode image. Although multiple microcode versions for a specific interface type can be stored concurrently in Flash memory, only one image can load at startup.
The show controllers cbus command displays the currently loaded and running microcode version for each interface processor and the VIP6-80. The show startup-config EXEC command shows the current system instructions for loading microcode at startup.
Software and interface processor microcode images are bundled to work together. Overriding the bundle can result in system incompatibilities. We recommend that you use the microcode included in the software bundle. For information on upgrading software and microcode in Cisco 7500 series routers, see the Cisco IOS Software Configuration Fundamentals Configuration Guides for the mainline software release that you are running.
The VIP6-80 read-only memory (ROM) monitor, known as Rommon, is firmware. It runs a brief set of system diagnostics, initializes the VIP6-80 hardware, and downloads a copy of the Cisco IOS image. The ROM monitor loads the Cisco IOS image from Flash memory or from a TFTP server. While multiple Cisco IOS images can be stored in RSP Flash memory, just one can be loaded at system startup.
The VIP6-80 ROM monitor functions similarly to the boot loader image on the RSP, which runs a copy of the Cisco IOS image. The boot loader image allows the router to access the Cisco IOS image when powering up or initializing the system.
The VIP6-80 supports up to two single-width port adapters, or one dual-width port adapter. Figure 1 shows a VIP6-80 with two single-width port adapter slots. A dual-width port adapter occupies both port adapter slots (not shown).
To ensure proper airflow in the router and compliance with EMI prevention standards, a VIP6-80 with one single-width port adapter must have a blank port adapter installed in the empty port adapter slot location.
VIP6-80 does not support OIR of PAs. To install or replace port adapters, first remove the VIP6-80.
|
Note A VIP6-80 without at least one installed port adapter is not supported. |
The VIP6-80 does not support the PA-GE, but the Cisco 7500 series routers support the Gigabit Ethernet Interface Processor (GEIP) and the Enhanced Gigabit Ethernet Interface Processor.
Table 4 identifies the port adapters supported by the VIP6-80 at the time of this writing, and Table 5 identifies the interface processors and service adapters that are supported by the VIP6-80.

For more information on the available port adapters, interface processors, and service adapters supported by the VIP6-80, refer to the Cisco Product Catalog online, or contact a Cisco sales representative. For more information on a specific port adapter, refer to the specific port adapter installation and configuration guide. The port adapters, including part numbers for ordering, are listed in the Cisco Port Adapter Documentation flyer. This document is available online at http://www.cisco.com/univercd/cc/td/doc/product/core/12939paf.htm .
The VIP6-80 physical specifications are listed in Table 6.
Table 6 VIP6-80 Specifications
The Cisco 7505, Cisco 7507, Cisco 7507-MX, Cisco 7513, Cisco 7513-MX, and Cisco 7576 routers support downloadable system software and microcode for most Cisco IOS and microcode upgrades. This enables you to remotely download, store, and boot from a new image. For information on upgrading software and microcode in Cisco 7500 series routers, see the Cisco IOS Configuration Fundamentals Configuration Guides for the mainline software release that you are running.
The Cisco IOS software images reside in Flash memory, in the form of a dual in-line memory module (DIMM). Flash memory contains the default system software image and bundled microcode images. Storing the Cisco IOS images in Flash memory enables you to download and boot from upgraded Cisco IOS images remotely or from software images resident in the VIP6-80 Flash memory.
For the latest software release information, refer to the Software Advisor at http://www.cisco.com/cgi-bin/Support/CompNav/Index.pl .
At system startup, an internal system utility scans for compatibility problems between the installed interface processor types and the bundled microcode images. The utility then decompresses the images into running dynamic random-access memory (DRAM). The bundled microcode images then function the same as the EPROM images.
The VIP6-80 supports the following:
This section provides installation prerequisites to ensure a successful VIP6-80 installation, and includes the following sections:
The minimum Cisco IOS Release requirements for VIP6-80 are listed in Table 7. For configuration information and support, refer to the modular configuration and modular command reference publications in the Cisco IOS software configuration documentation set that corresponds to the software release installed on your Cisco hardware.

Table 7 VIP6-80 Minimum Software Release Requirements
The VIP6-80 is a single motherboard. It operates with the following:
|
Note The VIP6-80 requires at least one port adapter installed in order to be supported. A single-width port adapter must have a blank port adapter installed in the empty port adapter slot location. |
Upgradable microcode on each interface processor contains board-specific software instructions.These microcode images come bundled with Cisco IOS software, and the images load automatically when a new software image is installed. (New microcode provides additional features and enhancements to interface processors.) Each Cisco IOS release works to optimize the bundled microcode images.
You need the following tools and parts to install or upgrade a VIP6-80:
|
Note The VIP6-80 requires at least one port adapter installed in order to be supported. A single-width port adapter must have a blank port adapter installed in the empty port adapter slot location. |
If you need additional equipment, contact a service representative for ordering information.
The VIP6-80 complies with the 89/366/EEc and 73/23/EEC directives, which can be found in the Regulatory Compliance and Safety Information for the Cisco 7500 Series Routers guide online at http://www.cisco.com/univercd/cc/td/doc/product/core/cis7505/4194pc75.htm .
Following are safety guidelines that you should apply when working with any equipment that connects to electrical power or telephone wiring.
Safety warnings appear throughout this publication in procedures that, if performed incorrectly, may harm you. A warning symbol precedes each warning statement.
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.
Use the following 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 (Mohms). |
This section describes the correct procedures to avoid unnecessary board failures.
|
Note The VIP6-80 installation is the same for each router model, except where otherwise noted. |
The VIP6-80 is oriented horizontally in the Cisco 7010 and Cisco 7505 routers, and vertically in the Cisco 7000, Cisco 7507, Cisco 7507-MX, Cisco 7513, Cisco 7513-MX, and Cisco 7576 routers.
Follow these guidelines when removing and installing the VIP6-80:
Figure 3 shows a detail of the ejector lever mechanism on the ends of the VIP.
Proceed to either the "Removing a VIP6-80" section to replace a VIP6-80 or to the "Installing a VIP6-80" section to install a new VIP6-80.
To install or remove a port adapter, see the "Removing and Installing Port Adapters" section.
This section describes the procedure for removing a VIP6-80.
|
Caution If your router has an RSP2 as the standby with the high system availability (HSA) feature or high availability (HA) features enabled, online insertion and removal of any interface processor in either CyBus might cause the standby RSP2 to reboot with a bus error or a processor memory parity error. The active RSP recovers from this event and issues a "cBus Complex Restart" message. Systems that are configured with an RSP4/4+, an RSP8, or an RSP16 as the system standby are not affected and do not experience this problem. For more information on HSA or HA, refer to your RSP installation and configuration guide. |
If your router has an RSP2 as the standby with the HSA feature or HA features enabled, perform the following steps before proceeding with the VIP6-80 removal:
Step 2 Remove the standby RSP2.
Step 3 Wait 20 to 30 seconds. This time will vary depending on the number of interfaces installed on your system.
This completes the additional steps you must perform if you have an RSP2 configured as the standby with HSA or HA enabled. Continue with the following steps to finish the removal of the VIP6-80 from the router.
Perform the following steps to remove a VIP6-80 from your router:
Step 2 Disconnect all cables from the VIP6-80 port adapter interface ports.
Step 3 Use a screwdriver to loosen the captive installation screws at both ends of the board. (See Figure 3a.)
|
Caution Always use the ejector levers to remove a VIP6-80. Failure to do so can cause erroneous system error messages indicating a board failure. |
Step 4 Place your thumbs on the ejector levers and simultaneously pull both of the ejector levers outward (in the direction shown in Figure 3a) to release the board from the backplane connector.
Step 5 Place the removed board on an antistatic mat or foam pad, or place it in an antistatic container if you plan to return it to the factory.
This completes the procedure for removing a VIP6-80. Proceed to the"Installing a VIP6-80" section.
|
Note If you have an RSP2 configured as the standby with HSA or HA enabled, continue with the following steps to finish the removal of the VIP6-80 from the router. |
Step 2 Reinsert the standby RSP2.
This completes the procedure for removing a VIP6-80 if you have an RSP2 configured as the standby RSP with HSA feature or HA features enabled. Proceed to the "Installing a VIP6-80" section.
This section describes how to remove and install port adapters. It includes the following sections:
If you are not removing or installing a port adapter, proceed to the "Installing a VIP6-80" section.
Port adapters do not support OIR, so you must first remove the VIP6-80 before removing or installing the PA. Refer to the "Removing a VIP6-80" section if you have not already removed the VIP6-80.
To remove or install a port adapter, you need the following tools and parts:
|
Note Always handle the port adapter by the carrier edges and handle; never touch the port adapter components or connector pins. (See Figure 4.) |
Single-width port adapters occupy one of the two port adapter slots on a VIP6-80. When a single-width port adapter slot is not in use, use a blank port adapter to fill the empty slot to allow the router to conform to EMI emissions requirements and to allow proper airflow through the router. If you plan to install a new single-width port adapter in a port adapter slot that is not in use, first remove the blank port adapter.
Figure 5 describes the steps required to install a single-width port adapter.
Dual-width port adapters occupy both port adapter slots on a VIP6-80. Before you can install a dual-width port adapter, first remove the slot divider located between the two port adapter slots. (See Figure 6.) Refer to Table 4 for a list of dual-width port adapters.
Use the following procedure to remove the slot divider from a VIP6-80:
Step 2 Remove the four slot divider screws that secure the slot divider to the VIP6-80 motherboard. (See Figure 6.)
Step 3 Remove the slot divider and store it (and the screws) in a location where you can retrieve it for use later.
|
Note If you need to reinstall the port adapter slot divider, place the slot divider in position on the VIP6-80 and secure it with the four Phillips screws. |
Step 4 See Figure 7 for the steps to install or remove a dual-width port adapter.
Refer to the Installation and Configuration Guide that shipped with your specific port adapter for cabling instructions.
This section describes the procedure for installing a VIP6-80, or for inserting an interface filler.
|
Note To ensure compliance with EMI approvals by providing a tight EMI seal for the Cisco 7500 and the Cisco 7000 series routers, install interface processors first in the interface processor slots closest to the RSP slots, and then work out to the interface processor slots furthest from the RSP slots. Refer to the "Product Description" section for more information on the interface processor slots on your router. |
If you removed a VIP6-80 and do not intend to replace it with another VIP in its slot, follow this procedure to insert an interface processor filler in the empty slot.
Figure 3 shows the functional details of inserting the VIP6-80 and using the ejector levers. Figure 2 shows proper handling of the VIP6-80 during installation.
|
Caution Remove or insert only one VIP6-80 at a time. Disrupting the sequence before the system has completed verification can cause the system to detect spurious hardware failures. |
Use the following procedure to install a new VIP6-80:
Step 2 Ensure that a console terminal is connected to the console port (on the RSP or RSP7000) and that your console is turned on, or that you have a reliable Telnet connection to the system.
Step 3 Hold the VIP6-80 handle with one hand and place your other hand under the carrier to support the VIP6-80 and guide it into the slot. (See Figure 2.) Avoid touching the card or any connector pins.
|
Caution To prevent ESD damage, handle interface processors by the handles and carrier edges only, similar to that shown for port adapters in Figure 4. |
Step 4 Place the back of the VIP6-80 in the slot and align the notch on the carrier with the groove in the slot. (See Figure 3.)
Step 5 While keeping the VIP6-80 parallel to the backplane, carefully slide it into the slot until the back of the faceplate makes contact with the ejector levers, and then stop. (See Figure 3b.)
|
Caution Use the ejector levers when installing or removing interface processors. An interface processor that is partially seated in the backplane might cause the system to hang and subsequently crash, and shoving or slamming the interface processor into the slot can damage the backplane pins and board. |
Step 6 Using your thumbs, simultaneously push both ejector levers inward until the VIP6-80 is pushed entirely into its slot. (See Figure 3c.)
Step 7 Tighten both of the captive installation screws to ensure proper EMI isolation for the router.
Step 8 Repeat Step 1 through Step 7 to install any additional interface processors.
This completes the procedure for installing a VIP6-80.
To configure the new interface, use the configuration section of the specific port adapter installation and configuration guide, or the Cisco IOS software configuration documentation listed in the "Related Documentation" section. The documentation is available online on Cisco.com, and on the Documentation CD-ROM.
After a VIP6-80 is reinstalled, the system brings online only port adapter interfaces that match the current configuration and were previously configured as up; all others require that you configure them with the configure command.
To configure the interfaces on the PAs installed on your VIP6-80, first enable the router as described below.
Step 2 Enter the password (the password is case sensitive). For security purposes, the password is not displayed.
When you enter the correct password, the system displays the privileged-level system prompt (#):
This completes the procedure for enabling the router.
For a complete description of commands and configuration options available for your VIP6-80, refer to the configuration section of the specific port adapter installation and configuration guide and to the appropriate Cisco IOS software configuration publications. (See the "Related Documentation" section.)
This section describes the procedures you can use to verify your VIP6-80 installation, and includes information on the following topics:
This section describes how to verify the VIP6-80 installation by observing the port adapter LED states and the information displayed on your console terminal.
|
Note The VIP6-80 has no LEDs that are visible or usable when the VIP6-80 is installed. The port adapters you install on the VIP6-80 have status and interface LEDs. |
When the system has reinitialized all interfaces, the enabled LED on the VIP6-80 port adapters should go on, depending on your connections and configuration. The console screen also displays a message as the system discovers each interface during its reinitialization.
The following sample display shows the events logged by the system as a VIP6-80 with a Gigabit Ethernet port adapter was removed from interface processor slot 2; the system then reinitialized the remaining interface processors and marked as down the Gigabit Ethernet interface on the VIP6-80 that was removed from slot 2. When you reinsert the VIP6-80, the system automatically brings up the interfaces that were up when the VIP6-80 was removed. (A Gigabit Ethernet interface is used in the following examples.)
|
Note When a new VIP6-80 is inserted or when a VIP6-80 is moved to a new slot, the system recognizes the new interfaces but leaves them in the shutdown state until you configure them and change their state to up. |
The following sample display shows the events logged by the system as you insert a new VIP6-80 in interface processor slot 3. (A Gigabit Ethernet interface is used in the following example.)
Use the following procedure to verify that the VIP6-80 is installed correctly:
Step 2 Verify that the enabled LED on each port adapter goes on and remains on after the reinitialization is complete. If the enabled LED remains on, proceed to Step 5. If it does not, proceed to Step 3.
Step 3 If the enabled LED on a port adapter fails to go on, the VIP6-80 may not be fully seated. Loosen the captive installation screws, and firmly push both ejector levers into place until they are approximately in the same orientation as the VIP6-80 faceplate. Tighten the captive installation screws. After the system reinitialization, the enabled LED on the port adapter should go on and remain on. If it does, proceed to Step 5. If it does not, proceed to Step 4.
Step 4 If the enabled LED still fails to go on, remove the VIP6-80 and install it in another available interface processor slot.
Step 5 If the VIP6-80 is new and not a replacement, configure the new interfaces using the configuration section of your port adapter installation and configuration guide.
|
Note New interfaces are not available until you configure them. |
Step 6 If the VIP6-80 is a replacement, use the show interfaces type interface-processor-slot- number/port-adapter-slot-number/interface-port-number command or the show controllers command to verify the status of the interfaces. (See the "Using show Commands to Verify the VIP6-80 Status" section.)
If you replaced a VIP6-80 with a new VIP6-80 with a greater number of interfaces (for example, if you replaced a VIP6-80 with a single port adapter with a VIP6-80 with two port adapters), the system recognizes the interfaces on the previously configured port adapter but does not recognize the additional port adapter interfaces. The new interfaces remain in the shutdown state until you configure them.
Step 7 When the interfaces are up, check the activity of each interface by observing the status LEDs, which are described in the appropriate LED section of your port adapter installation and configuration guide.
Step 8 If an interface LED fails to go on and a cable is connected to the interface port, check the cable connection and make certain it is properly seated in the connector.
Step 9 Repeat Step 1 through Step 8 to verify that any additional VIP6-80s are properly installed.
This completes the VIP6-80 installation.
If you experience other problems that you are unable to solve, contact TAC (see the "Technical Assistance Center" section), or a service representative for assistance.
To configure the new interface, use the configuration section of the specific port adapter installation and configuration guide, or the Cisco IOS software configuration documentation listed in the "Related Documentation" section. The documentation is available online on Cisco.com, and on the Documentation CD-ROM.
The following steps use show commands to verify that the new interfaces are configured and operating correctly.
Step 2 Display all the current interface processors and their interfaces with the show controllers command. Verify that the new VIP6-80 appears in the correct interface processor slot.
Step 3 Specify one of the new interfaces with the show interfaces type interface-processor-slot- number/port-adapter-slot-number/interface-port-number command and verify that the first line of the display specifies the interface with the correct slot number. Also verify that the interface and line protocol are in the correct state: up or down.
Step 4 Display the protocols configured for the entire system and specific interfaces with the show protocols command. If necessary, return to configuration mode to add or remove protocol routing on the system or specific interfaces.
Step 5 Display the running configuration file with the show running-config command. Display the configuration stored in the RSP NVRAM using the show startup-config 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 service representative for assistance.
This completes the procedure to verify that the new interfaces are properly configured, using the show commands.
|
Note The outputs that appear in this document may not match the output you receive when running these commands. The outputs in this document are examples only. |
This section describes using show commands to display interface information.
To display information about a specific interface, use the show interfaces command with the interface type and interface address in the format show interfaces type interface-processor-slot- number/port-adapter-slot-number/interface-port-number.
With the show interfaces command, use arguments such as the interface type and the interface address to display information about a specific interface only. The following example of the
show interfaces fastethernet command shows information specific to a VIP6-80 with a Fast Ethernet port adapter (PA-2FE) installed; the VIP6-80 is installed in interface processor slot 1:
To display hardware information about all of the interface processors in your router, including the VIP6-80, use the show controllers cbus command.
Following is an example of the show controllers cbus command used with a Cisco 7500 series router:
To display hardware information about a specific interface on a VIP6-80 port adapter, append the type argument (fastethernet, hssi, and so forth) and the interface address argument (interface-processor-slot-number/port-adapter-slot-number/interface-port-number) to the
show controllers command.
Following is an example of the syntax for this command for the interface on a PA-2FE port adapter installed in port adapter slot 1 of a VIP6-80 installed in interface processor slot 1 of a Cisco 7000 series or Cisco 7500 series router:
To display the configuration of the system hardware (the number of each interface processor type installed), the software version, the names and sources of configuration files, and the boot images, use the show version (or show hardware) command.
Following is an example of the show version command used with a Cisco 7500 series router:
To determine specific hardware configuration information about a VIP6-80 installed in your system (including the amount of installed CPU and packet memory), use the show diag slot command.
Specific information is displayed, as shown in the following example of a VIP6-80 with a PA-2FE port adapter; the VIP6-80 is installed in interface processor slot 4:
|
Note In the preceding command output, the line that begins with Controller Memory Size shows the amount of memory installed on the VIP6-80. If you plan a memory upgrade, make a note of these indicated memory values, then compare them after you upgrade memory to verify the upgrade. |
This section provides brief descriptions of the ping command. The ping command allows you to verify that an interface port is functioning properly and to check the path between a specific port and connected devices at various locations on the network. After you verify that the system and VIP6-80 have booted successfully and are operational, you can use this command to verify the status of the VIP6-80 interface ports. Refer to the publications listed in the "Related Documentation" section for detailed command descriptions and examples.
The ping command sends an echo request out to a remote device at an IP address that you specify. After sending a series of signals, the command waits a specified time for the remote device to echo the signals. Each returned signal is displayed as an exclamation point (!) on the console terminal; each signal that is not returned before the specified timeout is displayed as a period (.). A series of exclamation points (!!!!!) indicates a good connection; a series of periods (.....) or the messages [timed out] or [failed] indicate that the connection failed.
Following is an example of a successful ping command to a remote server with the IP address 10.1.1.60:
If the connection fails, verify that you have the correct IP address for the server and that the server is active (powered on), and repeat the ping command.
For complete descriptions of interface subcommands and the configuration options available for VIP6-80-related interfaces, and which commands support VIP6-80 functionality, refer to the publications listed in the "Related Documentation" section.
The following sections discuss maintenance procedures you might need for your VIP6-80 and port adapters:
Single Line Card Reload (SLCR) is a feature that speeds recovery of a failed router by reloading a failed line card without reloading other line cards on the network backplane. SLCR isolates the fault to a single Versatile Interface Processor (VIP6-80) or legacy interface processor card (lps), and accelerates recovery time by reloading only the faulty VIP or lps. Physical lines and routing protocols on the other line cards of the network backplane remain active. The system continues forwarding packets with minimal interruptions.
SLCR is disabled by default and needs to be manually configured. For more information on how to configure SLCR, refer to the Cisco 7500 Single Line Card Reload feature module at http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120limit/120s/120s13/slcr .htm.
This section provides the guidelines and procedures for upgrading CPU memory (also called program memory) and packet memory on your VIP6-80.
To upgrade CPU memory on your VIP6-80, you must replace the SDRAM DIMM located in socket U1. To upgrade packet memory on your VIP6-80, you must replace the SDRAM DIMM located in socket U5. (See Figure 1.) The default memory configurations for the VIP6-80 are 64 MB of CPU memory and 64 MB of packet memory.
|
Note To upgrade CPU memory to 256 MB, use any allowable combination of CPU memory and packet memory. You do not need to have equal amounts of CPU memory and packet memory installed. |
|
Note In the output display of the show diag command (see page 30), the line that begins with Controller Memory Size shows the amount of memory installed on the VIP6-80. Make a note of these memory values, then compare them after you upgrade memory to verify the upgrade. |
The following Cisco Systems memory spare and upgrade kits are compatible with the VIP6-80:
Table 8 Memory Spare and Upgrade Kits
| Product | Description |
|---|---|
Upgrades VIP6-80 CPU memory or packetmemory from 64 to 128 MB, with one 128-MB SDRAM DIMM |
|
Upgrades VIP6-80 CPU memory from 64 to 256 MB, or from 128 MB to 256 MB, with one 256-MB SDRAM DIMM (This 256-MB memory option is for CPU memory only.) |
Depending on your system configuration, a memory upgrade might be required. Also, if a system problem is determined to be caused by a DIMM, a DIMM replacement might be required.
Figure 1 shows the locations of the CPU memory and packet memory SDRAM DIMMs on the VIP6-80.
|
Caution Handle the DIMM by the card edges only, and avoid touching the memory module, pins, or traces (the metal fingers along the connector edge of the DIMM). (See Figure 8.) |
|
Note Use only SDRAM DIMMs from Cisco Systems. A Cisco manufacturing part number appears on each SDRAM DIMM. |
Use the following procedure to remove the existing DIMMs:
Step 2 Place the VIP6-80 on an antistatic mat or pad and ensure that you are wearing an antistatic device, such as a wrist strap.
Step 3 Position the VIP6-80 so that the handles are away from you and the bus connectors are toward you—opposite of the position shown in Figure 2.
Step 4 Locate the DIMM and position the VIP6-80 so that you are facing the DIMM module you want to remove.
Step 5 Open the DIMM socket tabs on the DIMM to release the DIMM from the socket. (See Figure 9.) The DIMM is under tension in the socket; therefore, the DIMM might be released from the socket with some force.
Step 6 With the DIMM socket tabs open, grasp the ends of the DIMM between your thumbs and forefingers and pull the DIMM completely out of the socket. (See Figure 10.)
Step 7 Place a removed DIMM on an antistatic mat, and store it in an antistatic container to protect it from ESD damage.
Step 8 Repeat Step 4 through Step 7 for the remaining DIMM, if required for your upgrade.
This completes the DIMM removal procedure.
With the VIP6-80 handle away from you and the bus connector toward you, use the following procedure to install the new DIMM in the DIMM socket:
Step 2 Hold the DIMM between your thumbs and forefingers. (See Figure 8.)
Step 3 Insert the connector edge of the DIMM straight into the socket.
|
Caution When inserting the DIMM, use firm but not excessive pressure. If you damage a socket, you will have to return the VIP6-80 to the factory for repair. |
Step 4 Gently push the DIMM into the socket until the socket tabs close over the ends of the DIMM. (See Figure 11.) If necessary, rock the DIMM gently back and forth to seat it properly.
Step 5 Check to see if the DIMM is seated properly. If the DIMM appears misaligned, carefully remove it and reseat it in the socket. Push the DIMM firmly back into the socket until first one and then the other socket tab moves into place.
Step 6 Repeat Step 1 through Step 5 above if you are replacing more than one DIMM.
This completes the DIMM replacement procedure. Reinstall the VIP6-80 in the system. (Follow the steps in the "Installing a VIP6-80" section.) See the following section, "Checking the VIP6-80 Memory Upgrade," as required.
This section describes how you would verify the memory upgrade.
This completes the VIP6-80 memory upgrade verification.
This section includes information on VIP6-80 troubleshooting.
