VIP4 Installation Procedures
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:
•Guidelines for VIP4 Removal and Installation, page 15
•Removing a VIP4, page 18
•Installing a VIP4, page 19
•Performing a Basic Configuration, page 21
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 To ensure compliance with electromagnetic interference (EMI) approvals by providing a tight
EMI-preventiveseal for the Cisco 7500 series routers, we recommend that you first install VIP4s 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 VIP4” section on page 18 if you plan to replace a VIP4 with another VIP4,
or if you plan to install a newVIP4, 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 The online insertion and removal (OIR) instructions should be carefully followed. Failure to insert the
VIP4 properly can cause system error messages indicating a board failure. Westrongly recommend that
you removeor 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 verificationcan cause the system to detect spurious hardware
failures.
Note The VIP4 port adapters do not support OIR, so when removing or inserting a port adapter, the system
must be shut down first. The VIP4 must be uninstalled before removing or installing a port adapter.
