Product Numbers: VIP2-10(=), VIP2-15(=), VIP2-20(=), VIP2-40(=), VIP2-50(=), VIP2-10/15-UPG=, VIP2-10/40-UPG=, VIP2-15/40-UPG=, VIP2-20/40-UPG=, MEM-VIP250-8M-S=, MEM-VIP250-64M-D=, MEM-VIP250-128M-D=

Customer Order Number: DOC-782658=

This document describes the installation, configuration, and maintenance of the second-generation Versatile Interface Processor (VIP2) in the Cisco 7505, Cisco 7507, Cisco 7507-MX, Cisco 7513, Cisco 7513-MX, and Cisco 7576 routers—and in Cisco 7000 series routers using the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI).

The VIP2 supports online insertion and removal (OIR), which allows insertion and removal of a VIP2 without first shutting down the system. Online insertion and removal maximizes router availability by allowing the addition or removal of the VIP2 during system operation. For more information on OIR, see the "VIP2 Installation Procedures" section.

The VIP2 supports LAN and WAN port adapters (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. Because the VIP2 port adapters do not support OIR, when removing or inserting a port adapter, the system must be shut down first. The VIP2 must be removed from its interface processor slot before removing or installing a port adapter.

---

Note A VIP2 without any port adapters is not supported.

---

For complete descriptions of interface subcommands and the configuration options available for VIP2-related interfaces, refer to the configuration note for each of the port adapters installed on your VIP2 and to the appropriate Cisco IOS software configuration publications. (See the "Related Documentation" section.)

---

Note Throughout this publication, the term VIP2 is used to describe all VIP2 models. Where appropriate, differentiations are made between the specific VIP2 models: VIP2-10, VIP2-15, VIP2-20, VIP2-40, and VIP2-50.

Product Description

This section discusses the following topics:

•Internal Components

•Specifications

•How to Identify the VIP2 Model

•VIP2 and Port Adapter Compatibility

The VIP2 is the second generation of the interface processor for use with the Cisco 7000 series routers using the RSP7000, and Cisco 7500 series routers.

Figure 1 shows a VIP2-15 (or a VIP2-40) with installed port adapters. The VIP2 card and port adapters have handles that allow for easy installation and removal. Single in-line memory modules (SIMMs) contain the DRAM (U2 and U6), and a dual in-line memory module (DIMM) contains the SRAM (U5). You can install VIP2s in any available interface processor slots in your Cisco 7000 series or 7500 series router.

The VIP2 port adapters do not support OIR, so when removing or inserting a port adapter, the system must be shut down first. The VIP2 must be removed from its interface processor slot before removing or installing a port adapter.

---

Note The VIP2 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.

---

Figure 1 VIP2-15 or VIP2-40 with Two Port Adapters (Horizontal Orientation Shown)

Figure 2 shows a VIP2-50 with installed port adapters. The VIP2-50 card and port adapters have handles that allow for easy installation and removal. The VIP2-50 firmware (microcode), which contains card-specific software instructions, resides in a programmable read-only memory (PROM) device. A dual in-line memory module (DIMM) contains the SDRAM, and a daughter card contains the SRAM. You can install VIP2-50s in any available interface processor slots in your Cisco 7000 series or Cisco 7500 series router.

Figure 2 VIP2-50 with Two Port Adapters (Horizontal Orientation Shown)

---

Note In the Cisco 7000, Cisco 7507, Cisco 7513 and Cisco 7576 chassis, the VIP2 is installed vertically. In the Cisco 7010 and Cisco 7505 chassis, the VIP2 is installed horizontally.

---

The VIP2 installs in any interface processor slot on your router, as noted below:

•Slots 0, 1, 2, 3, or 4 in the Cisco 7000 router

•Slots 0, 1, or 2 in the Cisco 7010 router

•Slots 0, 1, 2, or 3 of the Cisco 7505 router

•Slots 0, 1, 4, 5, or 6 of the Cisco 7507 router

•Slots 0, 1, 2, 3, 4, or 5, and 8, 9, 10, 11, or 12 of the Cisco 7513 router

•Slots 0, 1, 2, 3, 4, or 5 of Router A, and slots 8, 9, 10, 11, or 12 of Router B in the Cisco 7576 router

For more information on interface processor slots on your router, refer to the Cisco 7500 Series Installation and Configuration Guide or the appropriate Quick Start Guide for the Cisco 7500 series routers, or refer to Cisco 7000 Hardware Installation and Maintenance manual for the Cisco 7000 series routers.

How to Identify the VIP2 Model

There are five different versions of the VIP2: the VIP2-10, the VIP2-15, the VIP2-20, the VIP2-40, and the VIP2-50. The VIP2-10, VIP2-15, VIP2-20, and VIP2-40 all use the same motherboard, but differ in the amount of DRAM and SRAM. You can upgrade to a higher performing VIP2 simply by upgrading the DRAM and SRAM. See "Upgrading VIP2 Memory" section for more information.

The VIP2-50 uses a different motherboard and SDRAM and SRAM memory devices than the other VIP2 models; therefore, you cannot install VIP2-50 SDRAM or SRAM memory devices on the earlier VIP2 models, and you cannot install DRAM or SRAM memory devices from earlier VIP2 models on the VIP2-50. Also, you cannot use DRAM designated for the Route Switch Processor (RSP) on the VIP2 models.

For additional VIP2 DRAM (or SDRAM) and SRAM information, refer to the document Upgrading Memory on the Second-Generation Versatile Interface Processor (VIP2) (Part Number 78-3323-xx, Order Number DOC-VIP2UPG=), which is available online, on the Documentation CD-ROM, or as a printed document. (Also refer to the "Installation Prerequisites" section, for additional DRAM [or SDRAM] and SRAM prerequisites.)

You can identify your VIP2 model using the show diag command and observing either of the following output:

•SRAM and DRAM memory

•EEPROM value

Identifying the VIP2 Model Using show diag command and SRAM and DRAM Memory Output

Observe the memory configurations in the "Controller Memory Size" row to determine your VIP2 model, as follows:

Table 4 VIP2 Memory Configurations 

VIP	SRAM Memory	DRAM Memory
VIP2-10	512 KB SRAM	8 MB DRAM
VIP2-15	1 MB SRAM	8 MB DRAM
VIP2-20	1 MB SRAM	16 MB DRAM
VIP2-40	2 MB SRAM	32 MB or 64 MB DRAM

---

Note The VIP2-50 is a different motherboard, and in the show diag output you will see "VIP2 R5K controller".

---

In the following example, observing the "Controller Memory Size" row of the show diag output shows a VIP2-40 installed.

VIP2 and Port Adapter Compatibility

The port adapters attach to the VIP2 motherboard. (See Figure 1.) Port adapter installation requirements for the VIP2-50 are identical to the requirements for the all other VIP2 models.

Each port adapter contains the electrical interfaces and physical connections for the VIP2 interface types to connect to your network. (For the available port adapters supported by the VIP2 models, refer to the Cisco Product Catalog or contact a Cisco sales representative in your area.)

---

Note To ensure proper airflow in the chassis and compliance with electromagnetic interference (EMI) prevention standards, VIP2s with a single port adapter must have a blank port adapter installed in the empty port adapter slot location, as shown in Figure 3.

---

---

Note A VIP2 without at least one installed port adapter is not supported

---

Microcode Overview

The VIP2 microcode (firmware) is an image that provides card-specific software instructions. A programmable read-only memory (PROM) device on the VIP2 contains a default microcode boot image that assists the system in finding and loading the microcode image from the Cisco IOS bundle or Flash memory. The router supports 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 and, with a configuration command, instruct the system to load any one of them or the default microcode image.

The microcode boot image in the PROM initializes the VIP2 and then assists downloading the VIP2 microcode image. All interfaces of the same type (VIP2, and so on) will load the same microcode image, either from the microcode image bundled with the Cisco IOS or from an image stored in system Flash memory. 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 VIP2. The show startup-config EXEC command shows the current system instructions for loading microcode at startup.

Software and interface processor microcode images are carefully optimized and 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 a complete description of microcode and downloading procedures, refer to the "Upgrading VIP2 Microcode" section.

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 when potentially hazardous conditions exist.

•Never assume that power has been 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. Port adapters and processor modules consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap during handling.

Following are guidelines for preventing ESD damage:

•Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

•Connect the equipment end of the strap to an unfinished chassis surface.

•When installing a component, use any available ejector levers or captive installation screws to properly seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly seated.

•When removing a component, use any available ejector levers or captive installation screws to release the bus connectors from the backplane or midplane.

•Handle carriers by available handles or edges only; avoid touching the printed circuit boards or connectors.

•Place a removed component board-side-up on an antistatic surface or in a static shielding container. If you plan to return the component to the factory, immediately place it in a static shielding container.

•Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components from ESD voltages on the body; ESD voltages on clothing can still cause damage.

•Never attempt to remove the printed circuit board from the metal carrier.

---

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

What is the Cisco 7000 Series?

The Cisco 7000 series consists of the Cisco 7000 and Cisco 7010 routers. The VIP2 operates in the Cisco 7000 series routers providing these routers have the 7000 Series Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI) installed. (For software and hardware requirements, refer to the "Installation Prerequisites" section.)

Network interfaces reside on modular interface processors, including the VIP2, which are inserted into interface processor slots and provide a direct connection between external networks and the high-speed CxBus in the Cisco 7000 series. The Cisco 7000 series supports any combination of available VIP2 port adapter-based network interface types.

In the seven-slot Cisco 7000, slot 5 is reserved for the RSP7000 (7000 RSP slot shown in Figure 4), which contains the system processor and performs packet switching functions, and slot 6 is reserved for the RSP7000CI (7000 CI slot shown in Figure 4), which contains all of the environmental monitoring functions for the Cisco 7000. The remaining five slots (slots 0 through 4) are for interface processors and most combinations of VIP2-based network interface types.

Figure 4 Cisco 7000 with RSP7000 and RSP7000CI Installed (Interface Processor End)

In the five-slot Cisco 7010, slot 3 is reserved for the RSP7000 (7000 RSP slot shown in Figure 5), which contains the system processor and performs packet switching functions, and slot 4 is reserved for the RSP7000CI (7000 CI slot shown in Figure 5), which contains all of the environmental monitoring functions for the Cisco 7010. The remaining three slots (slots 0 through 2) are for interface processors and most combinations of VIP2-based network interface types.

Figure 5 Cisco 7010 with RSP7000 and RSP7000CI Installed (Interface Processor End)

What Is the Cisco 7500 Series?

The Cisco 7500 series consists of the Cisco 7505, Cisco 7507, Cisco 7507-MX, Cisco 7513, Cisco 7513-MX and Cisco 7576 routers. The VIP2 operates in all Cisco 7500 series routers. (For software and hardware requirements, refer to the "Installation Prerequisites" section.)

Network interfaces reside on modular interface processors, including the VIP2, which are inserted into interface processor slots and provide a direct connection between external networks and the high-speed CyBus in the Cisco 7500 series. The Cisco 7500 series supports most combinations of available VIP2 port adapter-based network interface types.

Figure 6, Figure 7, and Figure 8 show the rear of the Cisco 7500 series routers: the five-slot Cisco 7505, the seven-slot Cisco 7507 and Cisco 7507-MX, and the thirteen-slot Cisco 7513 and Cisco 7513-MX, respectively.The Cisco 7576 router is two Cisco 7500 series routers configured on a single split backplane, with 13 slots, which looks similar to the thirteen-slot Cisco 7513. Router A uses interface processor slots 0 through 5 with a Route Switch Processor in slot 6. Router B uses interface processor slots 8 through 12 with a Route Switch Processor in slot 7.

Figure 6 shows the rear of the five-slot Cisco 7505. Slot 4 is reserved for the Route Switch Processor (RSP1 or RSP4), which contains the system processor and performs packet switching functions. Slots 0 through 3 are for interface processors and most combinations of VIP2-based network interface types.

Figure 6 Cisco 7505 (Interface Processor End)

Figure 7 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 or RSP4), which contains the system processor and performs packet switching functions. Slots 0, 1, and 4 through 6 are for interface processors and most combinations of VIP2-based network interface types.

Figure 7 Cisco 7507 (Interface Processor End)

Figure 8 shows the rear of the thirteen-slot Cisco 7513 with two AC-input power supplies installed. Two slots (6 and 7) are reserved for the second-generation Route Switch Processor (RSP2 or RSP4), which contains the system processor and performs packet switching functions. Slots 0 through 5 and 8 through 12 are for interface processors and most combinations of VIP2-based network interface types.

VIP2 Installation Procedures

This section describes the procedures for removing or installing a VIP2 in the Cisco 7000 series or Cisco 7500 series routers:

•Guidelines for VIP2 Removal and Installation

•Removing a VIP2

•Installing a VIP2

•Performing a Basic Configuration

VIP2 installation is the same for each router model, except where otherwise noted.

The VIP2 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.

---

Note The functionality is the same for each router model; therefore, the term the chassis is used except where specific model issues arise.

---

Each unused interface processor slots must contain an interface processor filler (an interface processor carrier without a printed circuit board) to keep dust out of the router and to maintain proper airflow through the interface processor compartment.

---

Note To ensure compliance with electromagnetic interference (EMI) approvals by providing a tight EMI-preventive seal for the Cisco 7500 series routers, we recommend that you first install VIP2s in the interface processor slots closest to the RSP slots, and then work out to the interface processor slots furthest from the RSP slots.

---

Proceed to the "Removing a VIP2" section if you plan to replace a VIP2 with another VIP2, or if you plan to install a new VIP2, in which case you would first remove an existing interface processor or interface processor filler from an unused slot.

To install or remove a port adapter, see the "Installing or Replacing Port Adapters on the VIP2" section.

---

Note For proper operation with the VIP2, we recommend that your RSP1, RSP2, RSP4,/4+, or RSP7000 has at least 32 MB of DRAM.

---

Guidelines for VIP2 Removal and Installation

This section describes the correct procedures to avoid unnecessary board failures.

---

Caution The online insertion and removal (OIR) instructions should be carefully followed. Failure to insert the VIP2 properly can cause system error messages indicating a board failure. We strongly recommend that you remove or insert only one interface processor at a time. You must allow the system time to complete the initialization process before removing or inserting another interface processor. Disrupting the sequence before the system completes its verification can cause the system to detect spurious hardware failures.

---

---

Note The VIP2 port adapters do not support OIR, so when removing or inserting a port adapter, the system must be shut down first. The VIP2 must be uninstalled before removing or installing a port adapter.

---

You can remove and replace interface processors, such as the VIP2, while the system is operating, with minimal disruption.When an interface processor is added or removed, the switching complex is paused while the internal data structures are rebuilt for the new interface configuration. During this time, packets are not switched through the system. However, routing adjacencies and forwarding entries are maintained throughout the insertion and removal process.

After a VIP2 is reinstalled, the system brings online 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 more information on the configure command, refer to the documentation of the specific port adapter or interface processor that you are installing.

Figure 9 shows a detail of the ejector lever mechanism on the ends of the interface processor. Use the ejector levers when removing an interface processor to ensure that the backplane connector pins disconnect from the interface processor in the sequence expected by the system. Any interface processor that is only partially connected to the backplane can hang the bus.

---

Caution Failure to use the ejector levers and insert the interface processor properly can disrupt the order in which the pins make contact with the card or interface processor. This may cause the system to interpret a board failure.

---

---

Note The VIP2 is oriented horizontally in the Cisco 7010 and Cisco 7505 and vertically in the Cisco 7000, Cisco 7507, and Cisco 7513.

---

---

Note Handle processor modules by the carrier handles and carrier edges only; never touch the board or any connector pins. (See Figure 10.)

---

Figure 10 Handling Interface Processors—Horizontal Orientation Shown

Removing a VIP2

This section describes the procedure for removing a VIP2, an interface processor, or an interface processor filler, and replacing it with a new VIP2. Please read the "VIP2 Installation Procedures" section before proceeding with this procedure.

---

Note To help prevent dust and contaminants from entering the chassis, do not leave the interface processor slot open. Either insert an interface processor filler in the empty slot, or proceed immediately to the "Installing a VIP2" section.

---

---

Caution In Cisco 7507, Cisco 7507-MX, Cisco 7513, or Cisco 7513-MX routers with the high system availability (HSA) or high availability (HA) feature 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 or an RSP8 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 does not have the HSA or HA feature enabled, perform only Step 4 through Step 7 in the following procedure. If the router has the HSA or HA feature enabled with an RSP2 configured as the system standby, we recommend that you perform all the steps in the following procedure:

---

Note A VIP2 without a minimum of one port adapter is not supported.

---

Use the following procedure to remove a VIP2:

---

Step 1 Attach an ESD-preventive wrist strap between you and any unpainted chassis surface.

Step 2 If you are replacing a failed VIP2, disconnect all cables from the VIP2 ports; however, if you are only moving a VIP2 to another slot, this step is not necessary.

Step 3 Use a screwdriver to loosen the captive installation screws at both ends of the board. (See Figure 9.)

---

Caution Always use the ejector levers to remove or install the VIP2. 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 ejectors outward (in the opposite direction from that show in Figure 9c) to release the VIP2 from the backplane connector.

Step 5 Use the VIP2 handle to carefully pull it straight out of the slot, keeping your other hand under the carrier to guide it. (See Figure 10.) Keep the VIP2 parallel to the backplane.

Step 6 Place the removed VIP2 on an antistatic mat or foam pad, or place it in an antistatic container if you plan to return it to the factory.

Step 7 If the interface processor slot is to remain empty, install a filler (MAS7K-BLANK) to keep dust out of the chassis and to maintain proper airflow inside the chassis. Do not leave the interface processor slot open. Immediately proceed to the "Installing a VIP2" section.

---

This concludes the removing a VIP2 procedure.

Installing a VIP2

This section provides the procedure for installing a VIP2. The processor modules are oriented horizontally in the Cisco 7010 and Cisco 7505 and vertically in the Cisco 7000, Cisco 7507, and the Cisco 7513. The VIP2 slides into an open interface processor slot and connects directly to the backplane. The interface processor slots are keyed to guide pins on the backplane, so the VIP2 can be installed only in an interface processor slot. Figure 9 shows the functional details of inserting an interface processor and using the ejector levers. Figure 10 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 its discovery and initialization before removing or inserting another interface processor. Disrupting the sequence before the system has completed verification can cause the system to interpret hardware failures.

---

Use the following procedure to install a VIP2:

---

Step 1 Ensure that a console terminal is connected to the console port (on the RSP or RSP7000) and that your console is turned on.

Step 2 Hold the VIP2 handle with one hand and place your other hand under the carrier to support the VIP2 and guide it into the slot. (See Figure 10.) Avoid touching the VIP2 or any connector pins.

---

Caution To prevent ESD damage, handle interface processors by the handles and carrier edges only.

---

Step 3 Place the back of the VIP2 in the slot and align the notch on the carrier with the groove in the slot. (See Figure 9.)

Step 4 While keeping the VIP2 parallel to the backplane, carefully slide it into the slot until the back of the faceplate makes contact with the ejector levers, then stop. (See Figure 9b.)

---

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 pause indefinitely and subsequently crash, and shoving or slamming the interface processor into the slot can damage the backplane pins and board.

---

Step 5 Using your thumbs, simultaneously push both ejector levers inward until the VIP2 is pushed entirely into its slot. (See Figure 9c.)

Step 6 Tighten both of the captive installation screws.

---

Caution To ensure proper electromagnetic interference (EMI) isolation for the chassis, make certain to tighten the captive installation screws on each VIP2 immediately after you install it and before proceeding with the installation of each remaining VIP2.

---

---

This ends the VIP2 installation procedure.

Performing a Basic Configuration

For complete descriptions of interface subcommands and the configuration options available for VIP2-related interfaces, refer to the configuration note for each of the port adapters installed on your VIP2 and to the appropriate Cisco IOS software configuration publications. (See the "Related Documentation" section.)

Checking the VIP2 Installation

This section describes the procedures you can use to verify your VIP2 installation, and includes information on the following topics:

•Verifying the VIP2 Installation, page 30

•VIP2 Maintenance Procedures, page 39

•Using show Commands to Display Interface Information, page 35

•Using the ping Command to Verify Network Connectivity, page 38

You can use the configure command to configure the interfaces on the port adapters installed on your VIP2. To use the configure command, enter the privileged level of the EXEC command interpreter with the enable command, as shown below. The system prompts 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 (>). Use the following procedure to enter the privileged level:

---

Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC command interpreter 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 on your console.

Step 3 When you enter the correct password and press Return, the system displays the privileged-mode system prompt (#) as follows:

Router#

---

Verifying the VIP2 Installation

After you install the VIP2 and connect cables (using connection procedures in the respective subsections of the configuration notes that shipped with your port adapters), verify the installation by observing the port adapter LED states and the information displayed on your console terminal.

---

Note The VIP2 has no LEDs that are visible or usable when the VIP2 is installed. The port adapters you install on the VIP2 have status and interface LEDs.

---

When the system has reinitialized all interfaces, the enabled LED on the VIP2 port adapters and on all interface processors 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.

When you remove and replace 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 a VIP2 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 VIP2 that was removed from slot 2. When you reinsert the VIP2, the system automatically brings up the interfaces that were up when the VIP2 was removed. (A Gigabit Ethernet interface is used in the following examples.)

Removal

Router# 

%OIR-6-REMCARD: Card removed from slot 2, interfaces disabled

%LINK-5-CHANGED: Interface FastEthernet2/0/0, changed state to administratively down

%LINK-5-CHANGED: Interface FastEthernet2/1/0, changed state to administratively down

Insertion

Router#

%OIR-6-INSCARD: Card inserted in slot 2, interfaces administratively shut down

%LINK-5-CHANGED: Interface FastEthernet2/0/0, changed state to up

%LINK-5-CHANGED: Interface FastEthernet2/1/0, changed state to up

---

Note When a new VIP2 is inserted or when a VIP2 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 with the configure command.

---

The following example display shows the events logged by the system as a new VIP2 is inserted in slot 3. (Fast Ethernet interfaces are used in the following examples.)

Router#

%OIR-6-INSCARD: Card inserted in slot 3, interfaces administratively shut down

%LINK-5-CHANGED: Interface FastEthernet3/0/0, changed state to administratively down

%LINK-5-CHANGED: Interface FastEthernet3/1/0, changed state to administratively down

Use the following procedure to verify that the VIP2 is installed correctly:

---

Step 1 While the system reinitializes each interface, observe the console display messages and verify that the system discovers the VIP2 as follows:

•If you installed a new VIP2, the system should recognize all new interfaces but leave them configured as down.

•If you replaced a VIP2, the system should recognize each interface and place it in the same state (up or down) each was in when you removed the VIP2.

Step 2 When the reinitialization is complete, verify that the enabled LED on each port adapter goes 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 a port adapter fails to go on, suspect that the VIP2 board connector is not fully seated in the backplane. Loosen the captive installation screws, and then firmly push both ejector levers into place until they are approximately in the same orientation as the VIP2 faceplate. Tighten the captive installation screws. After the system reinitializes the interfaces, the enabled LED on the port adapter should go 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 VIP2 and try installing it in another available interface processor slot.

•If the enabled LED goes on when the VIP2 is installed in the new slot, suspect a failed backplane port in the original interface processor slot.

•If the enabled LED still fails to go on, but other LEDs on the VIP2 go on to indicate activity, proceed to Step 5 to resume the installation checkout and suspect that the enabled LED on the port adapter has failed.

•If no LEDs on the VIP2 go on, suspect that the VIP2 is faulty. Contact a service representative to report the problem and obtain further instructions.

Step 5 If the VIP2 is new and not a replacement, you have to configure the new interfaces. Proceed to the appropriate configuration section for your port adapter. (This does not have to be done immediately, but new interfaces will not be available until you configure them.)

Step 6 If the VIP2 is a replacement, use the show interfaces type slot/port adapter/port or show controllers cbus command to verify the status of the interfaces. (Refer to the "VIP2 Maintenance Procedures" section.)

If you replaced a VIP2 with a new VIP2 with a greater number of ports (for example, if you replaced a single-port adapter VIP2 with a dual-port adapter VIP2), the system will recognize the interfaces on the previously configured port adapter, but will not recognize the additional port adapter interfaces. The new interfaces will 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 LED section of your port adapter installation and configuration guide.

Step 8 In general, if an interface LED fails to go on and a cable is connected to the port, check the cable connection and make certain it is properly seated in the connector.

If an error message is displayed 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 VIP2 installation. If you installed a new VIP2 or if you installed a replacement VIP2 with an additional port, you must now configure the new interface as described in the following section and in the appropriate Cisco IOS software configuration documentation listed in "Related Documentation" section. The documentation is available on Cisco.com and the Documentation CD-ROM.

Using the show Command to Verify VIP2 Status

The following procedure describes how to use the show commands to verify that the new interfaces are configured correctly:

---

Step 1 Display the system hardware configuration with the show version or show hardware commands. Ensure that the list includes all the currently installed interfaces. The following example illustrates the VIP2 hardware configuration using the show version command:

Step 2 Display all of the current interface processors and their interfaces with the show controllers cbus command. Verify that the new VIP2 appears in the correct slot.

Step 3 Specify one of the new VIP2 interfaces with the show interfaces type slot/port adapter/port 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 command show protocols. If necessary, return to the configuration mode to add or remove protocol routing on the system or specific interfaces.

Step 5 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 service representative for assistance.

•Use the show controllers cbus command to display the internal status of each interface processor, including the slot location, the card hardware version, and the currently-running microcode version. This command also lists each interface (port) on each interface processor, including the logical interface number, interface type, physical (slot/port adapter/port) address, and hardware (station address) of each interface. The following example shows a VIP2 with Fast Ethernet interfaces (port adapters) installed in interface processor slot 1:

•Use the show startup-config command to display the contents of the system configuration file stored in nonvolatile random access memory (NVRAM) or Flash memory. The configuration file should reflect all new configuration changes you made and wrote to memory with the show running-config command. A Fast Ethernet interface is used in the following example of the show startup-config command:

Router# show startup-config

Using 1652 out of 130048 bytes

(display text omitted)

•Use the show protocols command to display the global (system-wide) and interface-specific status of any configured Level 3 protocol, as follows:

Router# show protocols

Global values:

  Internet Protocol routing is enabled

FastEthernet3/1/0 is up, line protocol is up

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 VIP2 with a Fast Ethernet port adapter (PA-2FE) installed; the VIP2 is installed in interface processor slot 1:

Router# show interfaces fastethernet 1/0/0

To display hardware information about all of the interface processors in your router, including the VIP2, use the show controllers cbus command.

Following is an example of the show controllers cbus command used with a Cisco 7500 series router:

Router# show controllers cbus

      txq 48001A10, txacc 48001A12 (value 106), txlimit 110

To display hardware information about a specific interface on a VIP2 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 0 of a VIP2 installed in interface processor slot 1 of a Cisco 7000 series or Cisco 7500 series router:

Router# show controllers fastethernet 1/0/0

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:

Note In the preceding command output, the line that begins with Controller Memory Size shows the amount of memory installed on the VIP2. 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 completes the procedure for verifying the VIP2 status using the show commands.

Using the ping Command to Verify Network Connectivity

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 VIP2 have booted successfully and are operational, you can use this command to verify the status of the VIP2 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:

Router# ping 10.1.1.60 <Return>

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echoes to 10.1.1.60, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms

Router#

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 VIP2-related interfaces, and which commands support VIP2 functionality, refer to the publications listed in the "Related Documentation" section.

VIP2 Maintenance Procedures

The following sections discuss maintenance procedures you might need for your VIP2 and port adapters:

•Upgrading VIP2 Microcode

•Upgrading VIP2 Memory

•Checking the VIP2 Memory Upgrade

Upgrading VIP2 Microcode

The Cisco 7000 series and Cisco 7500 series routers support downloadable microcode, which enables you to upgrade microcode versions over the network. You can download new microcode versions and store multiple versions in Flash memory, and you can then 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 (unless the configuration states otherwise).

---

Note Software and interface processor microcode images are carefully optimized and bundled to work together. Overriding the Cisco IOS software bundle can result in system incompatibilities. We recommend that you use the microcode included in the Cisco IOS software bundle.

---

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 have to configure the router to use that image using the microcode vip2 flash command; then you can use the microcode reload command to manually load the new microcode file. Finally, you use the configure command to instruct the system to load the new image automatically at each system boot.

---

Note The appropriate microcode image runs from DRAM (or SDRAM) on the VIP2.

---

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 with the new image.

---

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

---

---

Caution Before you copy a file to system 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.

---

Use the following procedure to download (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

-#- ED --type-- --crc--- -seek-- nlen -length- -----date/time------ name

1   \ FFFFFFFF B4A18E0B 3F6494  30   4023316  Jun 26 1994 19:44:29 image/file/1

2   .. FFFFFFFF 8075AA5D 4118B4  23   111518   Jun 29 1994 11:05:57 image/file/2

12044568 bytes available (8533736 bytes used)

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. If you attempt to copy in a new image, and the size of the new image exceeds the available space in Flash memory, 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, use the command copy tftp:filename [ flash | slot0 | slot1 ]:filename to copy an image to Flash memory. (The file source is tftp:filename, and [ flash | slot0 | slot1 ]:filename is the destination in onboard Flash memory or on either of the Flash memory cards.)

An example of the copy tftp:filename command follows:

Router# copy tftp:vip11-1 slot0:vip11-1

20575008 bytes available on device slot0, proceed? [confirm]

Address or name of remote host [1.1.1.1]?

Step 4 Use the show flash command to verify that the microcode has been copied to Flash memory. The output should display the filename of the image you copied to Flash memory (vip11-1 in the following example):

Router# show flash

-#- ED --type-- --crc--- -seek-- nlen -length- -----date/time------ name

1   .. FFFFFFFF B4A18E0B 3F6494  30   4023316  Jun 26 1994 19:44:29 image/file/1

2   .. FFFFFFFF 8075AA5D 4118B4  23   111518   Jun 29 1994 11:05:57 image/file/2

3   .. FFFFFFFF EEA1FEEB 8436E8  22   600516     Oct 10 1995 19:35:25 vip11-1

7646052 bytes available (16179788 bytes used)

Step 5 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 configure terminal command, as follows:

Router# config terminal

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

Router(config)#

Step 6 Specify that you are changing the microcode for the VIP2 (microcode vip2), and that it will load from Flash memory (flash slot0 or slot1). Then add the filename of the new microcode image to be loaded from Flash memory:

Router(config)# microcode vip2 flash slot0:vip11-1

Step 7 To exit configuration mode, press Ctrl-Z.

Step 8 Copy the new configuration to nonvolatile random-access memory (NVRAM):

Router# copy running-config startup-config

The microcode reload command is automatically added to your running configuration. The new VIP2 microcode image will load automatically the next time the system boots or reinitializes.

Step 9 To load the new microcode immediately, you can issue the microcode reload configuration command (you must be in configuration mode to enter this command):

Router# config terminal

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

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 configuration mode and return to the system prompt.

Step 10 To verify that the VIP2 is using the correct microcode, issue the show startup-config or show controllers cbus command, which indicates the currently loaded and running microcode version for each interface processor.

Router# show controllers cbus

---

This completes the procedure for downloading microcode to Flash memory.

Upgrading VIP2 Memory

The procedures for upgrading memory devices on the VIP2 models are divided into the following sections:

•Installing the VIP2-10, VIP2-15, or VIP2-20 Memory Upgrade Kits

•Installing the VIP2-50 Memory Upgrade Kits

Choose the procedure appropriate for your VIP2 model. Refer to "How to Identify the VIP2 Model" section if to determine your VIP2 model.

Installing the VIP2-10, VIP2-15, or VIP2-20 Memory Upgrade Kits

This section provides the guidelines and procedures for installing the VIP2-10, VIP2-15, or VIP2-20 memory devices. In general, to upgrade memory on your VIP2-10, VIP2-15, or VIP2-20, you must replace both the SRAM and DRAM.

The VIP2-10, VIP2-15, and VIP2-20 models support the following SRAM and DRAM (or SDRAM for VIP2-50) memory upgrade products:

•VIP2-10/15-UPG=—1 MB of SRAM

•VIP2-10/40-UPG=—2 MB of SRAM and 64 MB of DRAM (also included are software licenses to use distributed switching [DSW] and distributed services [DS])

•VIP2-15/40-UPG=—2 MB of SRAM and 64 MB of DRAM (also included are software licenses to use DSW and DS)

•VIP2-20/40-UPG=—2 MB of SRAM and 64 MB of DRAM (also included are software licenses to use DSW and DS)

The following DRAM upgrade product is compatible with the VIP2-40: MEM-VIP240-64MB-D= (which upgrades a VIP2-40 to 32-MB SRAM and 64 MB of SDRAM).

The VIP2-50 model supports the following SDRAM memory upgrade products:

•MEM-VIP250-8M-S=—8-MB SRAM daughter card for the VIP2-50 only

•MEM-VIP250-64M-D=—64-MB SDRAM DIMM for the VIP2-50 only

•MEM-VIP250-128M-D=—128-MB SDRAM DIMM for the VIP2-50 only

---

Note There is no memory kit to upgrade the VIP2-40 to a VIP2-50. You must purchase a new VIP2-50 board.

---

Figure 11 shows the locations of the DRAM SIMMs and the SRAM DIMM on the VIP2-10, VIP2-15, VIP2-20, and VIP2-40.

Figure 11 Location of DRAM SIMMs and SRAM DIMM on the VIP2-10, -15, -20, and -40

The following sections provide DRAM and SRAM upgrade procedures for the VIP2-10, VIP2-15, VIP2-20, and VIP2-40 (DRAM only) models:

•Replacing the VIP2-10, VIP2-15, VIP2-20, or VIP2-40 DRAM SIMMs

•Replacing the VIP2-10, VIP2-15, or VIP2-20 SRAM DIMM

Replacing the VIP2-10, VIP2-15, VIP2-20, or VIP2-40 DRAM SIMMs

The 70-nanosecond (ns) DRAM on the VIP2-10, VIP2-15, VIP2-20, and VIP2-40 (hereafter called the VIP2) is contained in two single in-line memory modules (SIMMs) located in sockets U2 and U6. (See Figure 11.) Depending on your system configuration, a memory upgrade may be required. Also, if you determine that a system problem is caused by a SIMM, a SIMM replacement may be required.

---

Note The memory kit MEM-VIP240-64MB-D= requires you to replace only the DRAM SIMMs on your VIP2-40.

---

---

Caution To prevent ESD damage, handle SIMMs by the card edges only. Place removed SIMMs on an antistatic mat and store them in an antistatic bag.

---

Removing VIP2 DRAM SIMMs

Use the following procedure to remove DRAM SIMMs:

---

Step 1 Turn off the system power and remove the VIP2 from the system. (Follow the steps in "Removing a VIP2" section.)

Step 2 Place the VIP2 on an antistatic mat or pad, and ensure that you are wearing an antistatic device, such as a wrist strap. Position the VIP2 so that the handle is away from you, and the bus connector is toward you—opposite of the position shown in Figure 11.

Step 3 Locate the SIMMs. The DRAM SIMMs occupy sockets U2 and U6. (See Figure 11.)

Step 4 Release the spring clips from the SIMM that you want to remove and release the SIMM from the socket. (See Figure 12.)

Figure 12 Releasing the SIMM Spring Clips

Step 5 When both ends of the SIMM are released from the socket, grasp the ends of the SIMM with your thumb and forefinger and pull the SIMM completely out of the socket. Handle the edges of the SIMM only; avoid touching the memory module, pins, or traces (the metal fingers), along the socket edge. (See Figure 13.)

Step 6 Place the SIMM in an antistatic bag to protect it from ESD damage.

Step 7 Repeat Step 4 through Step 6 for the remaining SIMM, as required for this replacement.

---

This completes the SIMM removal procedure. Proceed to the next section to install the new SIMMs.

Installing New VIP2 DRAM SIMMs

SIMMs are sensitive components that are susceptible to ESD damage. Handle SIMMs by the edges only; avoid touching the memory modules, pins, or traces (the metal fingers along the connector edge of the SIMM). (See Figure 13.)

Figure 13 Handling a SIMM

---

Caution To prevent ESD damage, handle SIMMs as shown in Figure 13.

---

---

Note The memory kit MEM-VIP240-64MB-D= requires you to replace only the DRAM SIMMs on your VIP2-40.

---

Use the following procedure to install new DRAM SIMMs:

---

Step 1 With the VIP2 in the same orientation as the previous procedure (with the handle away from you and the bus connector toward you), you will install the first SIMM in the socket farthest from you and install the last SIMM in the socket closest to you.

Step 2 Remove a new SIMM from the antistatic bag.

Step 3 Hold the SIMM between your thumbs and forefingers, component-side-up, with the connector edge (the metal fingers) away from you.

Step 4 Tilt the SIMM to approximately the same angle as the socket and insert the connector edge into the socket.

---

Caution When inserting SIMMs, use firm but not excessive pressure. If you damage a socket, you will have to return the VIP2 to the factory for repair.

---

Step 5 Gently push the SIMM into the socket until the spring clips snap over the ends of the SIMM. If necessary, rock the SIMM gently back and forth to seat it properly.

Step 6 Repeat Steps 2 through 5 for the remaining SIMMs.

Step 7 When both SIMMs are installed, check all four alignment holes (two on each SIMM) and ensure that the spring clip is visible. If it is not, the SIMM is not seated properly. If any SIMM appears misaligned, carefully remove it and reseat it in the socket. Push the SIMM firmly back into the socket until the spring clips snap into place.

---

This completes the DRAM SIMM replacement procedure. If you need to replace the SRAM DIMM, proceed to the "Replacing the VIP2-10, VIP2-15, or VIP2-20 SRAM DIMM" section, and then reinstall the VIP2 in the chassis. (Follow the steps in the "Installing a VIP2" section.)

If you do not need to replace the SRAM DIMM, refer to the "Checking the VIP2 Memory Upgrade" section, as required.

Replacing the VIP2-10, VIP2-15, or VIP2-20 SRAM DIMM

The SRAM on the VIP2-10, VIP2-15, and VIP2-20 (hereafter called the VIP2) is contained in one dual in-line memory module (DIMM) located in socket U5. (See Figure 11 on page 42.) Depending on your system configuration, a memory upgrade may be required. Also, if you determine that a system problem is caused by the DIMM, a DIMM replacement may be required.

---

Caution To prevent ESD damage, handle the DIMM by the edges only. Place a removed DIMM on an antistatic mat and store it in an antistatic bag.

---

Step 7 Reinstall the VIP2-50 in the chassis. (Follow the steps in the "Installing a VIP2" section.)

---

This completes the VIP2-50 SRAM daughter card replacement procedure.

Checking the VIP2 Memory Upgrade

After you upgrade the VIP2 and reconnect cables, verify the upgrade by observing the LED states and the console display. When the system has reinitialized all interfaces, the enabled LED on the VIP2 and on all interface processors should go on. Port adapter LEDs should be on, depending on your connection. The console screen will display a message as the system discovers each interface during its reinitialization.

If, after you have replaced memory devices, the system fails to boot properly, or if the console terminal displays a checksum or memory error, check the following:

•Ensure that all memory devices are installed correctly. If necessary, shut down the system and remove the VIP2. Check the memory devices by looking straight down on them and then at eye level. The devices should be aligned at the same angle and the same height when properly installed. If a memory device appears to stick out or rest in the socket at a different angle from the others, remove the device and reinsert it; then replace the VIP2 and reboot the system for another installation check.

•Each SIMM or DIMM socket must contain SIMMs or a DIMM of the correct size and speed or the system will not operate. To ensure this, use only memory devices that are included with Cisco Systems memory kits.

If after several attempts the system fails to restart properly, contact a service representative for assistance. Before you call, make note of any error messages, unusual LED states, or any other indications that might help solve the problem.

Verify that the VIP2 is operating properly as follows:

---

Step 1 While the system reinitializes each interface, observe the console display messages and verify that the system discovers the VIP2 and recognizes each interface and places it in the same state (up or down) it was in when you removed the VIP2.

Step 2 When the reinitialization is complete, verify that the enabled LED on each port adapter goes 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 a port adapter fails to go on, suspect that the VIP2 board connector is not fully seated in the backplane. Loosen the captive installation screws, then firmly push both ejector levers into place until they are approximately in the same orientation as the VIP2 faceplate. Tighten the captive installation screws. After the system reinitializes the interfaces, the enabled LED on the port adapter should go 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 VIP2 and try installing it in another available interface processor slot.

•If the enabled LED goes on when the VIP2 is installed in the new slot, suspect a failed backplane port in the original interface processor slot.

•If the enabled LED still fails to go on, but other LEDs on the VIP2 go on to indicate activity, proceed to Step 5 to resume the upgrade verification and suspect that the enabled LED on the port adapter has failed.

•If no LEDs on the VIP2 go on, suspect that the VIP2 is faulty.

•If the enabled LED still does not go on, contact a service representative to report the problem and obtain further instructions.

Step 5 When the interfaces are up, check the activity of each interface by observing the status LEDs on the port adapters, which are described in the appropriate LED section of the configuration note that shipped with your port adapter.

---

Note In general, if an interface's LEDs fail to go on and a cable is connected to the port, check the cable connection and make certain it is properly seated in the connector.

---

If an error message is displayed 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 VIP2 memory upgrade procedures.

Installing or Replacing Port Adapters on the VIP2

Always handle the port adapter by the carrier edges and handle; never touch the port adapter components or connector pins. (See Figure 27.)

Figure 27 Handling a Port Adapter

---

Caution To prevent system problems, do not remove port adapters from the VIP2 motherboard or attempt to install other port adapters on the VIP2 motherboard while the system is operating. To install or replace port adapters, first remove the VIP2.

---

---

Warning When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the card. Some platforms have an ESD connector for attaching the wrist strap. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself.

---

To replace a port adapter, use the procedure that is appropriate to your port adapter type:

•Single-Width Port Adapter—For replacing a single-width port adapter on your VIP2

Single-Width Port Adapter

Single-width port adapters occupy one of the two port adapter slots on a VIP2. When a single-width port adapter slot is not in use, a blank port adapter must fill the empty slot to allow the router to conform to electromagnetic interference (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, you must first remove the blank port adapter.

Figure 28 describes the steps required to install a single-width port adapter.

Figure 28 Removing and Installing a Single-Width Port Adapter
