Introduction
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 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 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.
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.)

Note
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 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 VIP4 and then assists downloading the VIP4 microcode image. All interfaces 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 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 VIP4 Microcode" section.
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.

VIP4 Installation Procedures
This section includes procedures for VIP4 installation in the Cisco 7500 series or Cisco 7000 series routers, and includes information on the following topics:
•
•
VIP4 installation is the same for each router model, except where otherwise noted.
The VIP4 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.
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
Proceed to the "Removing a VIP4" section if you plan to replace a VIP4 with another VIP4, or if you plan to install a new VIP4, 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 a Port Adapter on a VIP4" section on page 35.
Guidelines for VIP4 Removal and Installation
This section describes the correct procedures to avoid unnecessary board failures.
Caution
Note
You can remove and replace interface processors (such as the VIP4) 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 VIP4 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 2 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.

Installing a VIP4
This section describes the procedure for installing a VIP4. The VIP4 slides into an open interface processor slot and connects directly to the backplane. The interface processors are keyed to guide pins on the backplane, so the VIP4 can be installed only in an interface processor slot. Please read the "Guidelines for VIP4 Removal and Installation" section, if you have not already done so, before proceeding.
Note
Figure 2 shows the functional details of inserting an interface processor and using the ejector levers. Figure 3 shows proper handling of an interface processor during installation.

•
You can use the configure command to configure the interfaces on the port adapters installed on your VIP4. 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
Router> enablePassword:Step 2
Step 3
Router#Verifying the VIP4 Installation
After you install the VIP4 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
When the system has reinitialized all interfaces, the enabled LED on the VIP4 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 VIP4 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 VIP4 that was removed from slot 2. When you reinsert the VIP4, the system automatically brings up the interfaces that were up when the VIP4 was removed. (A Gigabit Ethernet interface is used in the following examples.)
Removal

Step 5
Step 6
If you replaced a VIP4 with a new VIP4 with a greater number of interfaces (for example, if you replaced a VIP4 with a single port adapter with a VIP4 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
Step 8
If you experience other problems that you are unable to solve, contact a service representative for assistance.
This completes the VIP4 installation. If you installed a new VIP4 or if you installed a replacement VIP4 with an additional port, you must now configure the new interface as described in the configuration note that shipped with the port adapter or in the appropriate Cisco IOS software configuration documentation listed in the section " Related Documentation" on page 2. The documentation is available on Cisco.com and the Documentation CD-ROM.
