Verifying The Installation; Replacing Backplane Modules - Cisco Catalyst 4500e Series Installation Manual

Chapter 4 Removing and Replacing FRUs

Verifying the Installation

To check the operation of the fans, you need to power up the chassis.
Note
Follow these steps to verify that the new fan assembly was installed correctly:
Listen for the fans; you should immediately hear them operating. If you do not hear them, ensure that
Step 1
the fan assembly is inserted completely in the chassis and that the faceplate is flush with the switch back
panel.
The fan tray LED should light and be green.
Step 2
If after several attempts the fans do not operate, or if you experience trouble with the installation (for
Step 3
instance, if the captive installation screws do not align with the chassis holes), contact the Cisco TAC
for assistance.

Replacing Backplane Modules

There are 5 redundancy modules (also called mux buffers) and 1 clock module on a Catalyst 4507R-E
chassis backplane. A Catalyst 4510R-E has 8 redundancy modules on its backplane. They are accessible
from the front if the switching modules and supervisor engines are removed. There are two types of
redundancy modules, and they are interchangeable.
The clock module replacement procedure is identical to the redundancy module replacement procedure,
the connectors are the same. These modules are not hot-swappable, the switch must be taken out of
service to replace them.
To replace the backplane modules:
Make sure you are grounded with an ESD strap.
Step 1
Turn off the power to the chassis.
Step 2
Remove all supervisor engines and switching modules from the chassis, and find the backplane modules
Step 3
you need to replace.

Keep a record of switching module and their slots, so that you can put them back correctly.
