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

OL-3673-01

Checking the VIP4 Installation

Note The VIP4 has no LEDs that are visible or usable when the VIP4 is installed. The port adapters you install

on the VIP4 have status and interface LEDs.

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

Router#

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

%LINK-5-CHANGED: Interface GigabitEthernet2/0/0, changed state to administratively down

Insertion

Router#

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

%LINK-5-CHANGED: Interface GigabitEthernet2/0/0, changed state to up

Note When a new VIP4 is inserted or when a VIP4 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 VIP4 in

interface processor slot 3. (A Gigabit Ethernet interface is used in the following example.)

Router#

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

%LINK-5-CHANGED: Interface GigabitEthernet3/0/0, changed state to administratively down

Use the following procedure to verify that the VIP4 is installed correctly:

Step 1 While the system reinitializes each interface, observe the console display messages and verify that the

system discovers the VIP4 as follows:

• If you installed a new VIP4, the system should recognize all new interfaces but leave them

configured as down.

• If you replaced a VIP4, the system should recognize each interface and place it in the same state (up

or down) each was in when you removed the VIP4.

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.
