Product Numbers: VIP4-50=, VIP4-80=, MEM-VIP4-64M-SD=, MEM-VIP4-128M-SD=, MEM-VIP4-256M-SD=

This guide provides instructions for installing, configuring, and maintaining the fourth-generation Versatile Interface Processor (VIP4). The VIP4 operates with the Cisco 7505, Cisco 7507, Cisco 7507-MX, Cisco 7513, Cisco 7513-MX, and the Cisco 7576 routers with the Route Switch Processor (RSP1, RSP2, RSP4, RSP4+, or RSP8), and with the Cisco 7000 series routers using the 7000 Series Route Switch Processor(RSP7000) and 7000 Series Chassis Interface (RSP7000CI). See the “Software

Requirements” section on page 9 for specific compatibility requirements.

The VIP4 supports online insertion and removal(OIR), which allows you to remove and replace a VIP4 without first shutting down the system. Online insertion and removal maximizes router availability by letting you add or remove VIP4s during system operation. See the “Guidelines for VIP4 Removal and

Installation” section on page 15 for more information on removing and installing the VIP4.

The VIP4 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. For a list of supported port adapters, refer to the “VIP4

and Port Adapter Compatibility” section on page 7.

The VIP4 port adapters do not support OIR, so when removing or inserting a port adapter, the system must be shut down first. The VIP42 must be removed from its interface processor slot before removing or installing a port adapter.

For complete descriptions of interface subcommands and the configuration options available for VIP4-related interfaces, refer to the configuration note for each of the port adapters installed on your VIP4 and to the appropriate Cisco IOS software configuration publications. (See the “Related

Documentation” section on page 2.)

VIP4 Overview

What is the VIP4?

The VIP4 is the fourth generation of Versatile Interface Processors for use with Cisco 7500 or Cisco 7000 series routers. The VIP4 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 HardwareInstallation and Maintenance manual for the Cisco 7000 series routers.

How to Identify the VIP4 Model

There are two different versions of the VIP4: the VIP4-50 and the VIP4-80. Both VIP4 versions support two single-width port adapters or one dual-width port adapter and identical ECC-protected memory expansion options. Each VIP4 operates with the Cisco 7505, Cisco 7507, Cisco 7507-MX, Cisco 7513, Cisco 7513-MX, and the Cisco 7576 routers.

Traffic Management

• Simple Network Management Protocol (SNMP) agent V1 (RFCs 1155-1157)

• Management Information Base (MIB) II (RFC 1213)

Hardware Requirements

The VIP4 is a single motherboard. It operates with:

• Cisco 7505, Cisco 7507, Cisco 7507-MX, Cisco 7513, Cisco 7513-MX, and the Cisco 7576 routers

with the Route Switch Processor (RSP1, RSP2, RSP4, RSP4+, or RSP8); the RSP should have at least 64 MB of DRAM.

• Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series

Chassis Interface (RSP7000CI), the RSP7000 should have at least 64 MB of DRAM.

• Two single-width port adapters, or one dual-width port adapter, supporting multiple LAN and WAN

port adapter types, including Ethernet, Fast Ethernet, Gigabit Ethernet, serial, channelized serial, multichannel, HSSI, ATM, and POS.

Note The VIP4 requires at leastone port adapter installed inorder to be supported. Asingle-width port adapter

must have a blank port adapter installed in the empty port adapter slot location.

Microcode Overview

The VIP4 microcode (firmware) is an image that provides card-specific software instructions. A programmable read-only memory (PROM) device on the VIP4 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 storemultiple images for an interface type and, with a configuration command, instruct the system to load any one of them or the default microcode image.

Fourth Generation Versatile Interface Processor (VIP4) Installation and Configuration Guide

OL-3673-01

The microcode boot image in the PROM initializes the VIP4 and then assists downloading the VIP4 microcode image. Allinterfaces of the same type (VIP4, 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 VIP4. The show startup-config EXEC command showsthe 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 VIP4 Microcode” section on page 28.

ROM Monitor Overview

The VIP4 read-only memory (ROM) monitor, known as Rommon, is firmware. It runs a brief set of system diagnostics, initializes the VIP4 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 VIP4 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.

Safety Guidelines

• 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 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 followingguidelines when working with anyequipment 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.

Use the following 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.

• 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 board component-side-up on an antistatic surface or in a static shielding container;

otherwise, 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).
