Solution

Removing and Installing the Fan Tray

This section describes how to remove and install the system fan tray in the Catalyst 4948E switch chassis and
contains these subsections:

Required Tools:

You might need a flat-blade or Number 2 Phillips screwdriver to loosen or tighten the captive installation screw on the fan tray.

Note:   You have 30 seconds to install the replacement fan tray before the system automatically shuts down.

Removing the Fan Tray

The system fan tray  can be removed and replaced while the system is operating without presenting an electrical
hazard to the user or damage to the system. A 30-second window is provided for you to remove the defective fan
tray and install the replacement tray. If you exceed 30 seconds, the system starts to overheat and automatically
shuts down.

Warning:  When removing the fan tray, keep your hands and fingers away from the spinning fan blades. Let the fan blades
completely stop before you remove the fan tray.

To remove the installed fan assembly, follow these steps:

Step 1: Remove the replacement fan tray from its shipping packaging and place it near the chassis that you are working on.
Step 2: Loosen the two captive installation screws on the installed fan tray.
Step 3: Grasp the fan assembly handle, and pull it outward; gently move the fan tray from side to side, if necessary, to
            unseat the fan tray power connector from the chassis connector.
Step 4: Place your free hand under the fan tray to support it. Pull the fan assembly clear of the chassis, and set it aside.

Installing the Fan Tray


To install the new fan tray, follow these steps:

Step 1: Position the replacement fan tray in front of the fan tray bay at the rear of the chassis.
Step 2: Slide the fan tray into the fan tray bay until the power connector seats in the chassis fan connector and the
            captive installation screws make contact with the chassis. The fans should immediately power up.
Step 3: Tighten the two fan tray captive installation screws to secure the fan tray in the chassis.
Step 4: Verify that the FAN LED on the chassis front panel is lit green
