To check the operation of the fans, you need to power up the chassis.
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 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.
If after several attempts the fans do not operate, or if you experience trouble with
the installation (for instance, if the captive installation screws do not align with
the chassis holes), contact the Cisco TAC for assistance.
There are 5 redundancy modules (also called mux buffers) and 1 clock module on
a Catalyst 4507R chassis backplane. A Catalyst 4510 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.
Turn off the power to the chassis.
