Prepare the New Fan Tray

Unpack the new fan tray.

Inspect the new fan tray to verify that it is undamaged.

Place the new fan tray in a safe, accessible place near the 
switch, ready for prompt insertion.

Locate a #2 Phillips or cross-head screwdriver.

Remove the Old Fan Tray

Loosen the fan tray’s fastening screws.

At the front of the Alcatel Wireless LAN Switch, use the screwdriver to loosen 
both of the fastening screws on the faceplate of the installed fan tray. The 
screws loosen with counter-clockwise rotation, but are captive and cannot be 
fully removed.

Disengage the fan tray.

Grasp the module handle firmly and draw the fan tray forward from its slot. 
There may be moderate resistance as the module comes free from its 
connections with the chassis backplane, but do not use excessive force.

When the module is fully disengaged from the backplane, power to the 
working fans is lost and they will gradually stop spinning.

Fully remove the fan tray and place it safely aside.

Once disengaged, the fan tray should easily slide out of the switch chassis.

—The fans will continue to spin for a short while, even though 

there is no power to them. Wait for the fans to stop spinning before 
removing the fan tray.

Also, when hot swapping, once the fans stop spinning, the Alcatel 
Wireless LAN Switch will continue to operate, though heat will begin 
to build in the operational components. From this point, there is a 
limited time (approximately one minute) before installation of the new 
fan tray must be completed.
