Alcatel 6000 Fan Tray Assembly Installation Instructions 3
Replacing a Fan Tray
If hot-swapping the fan tray, please be aware that there are time-critical
aspects to parts of the procedure. To ensure proper preparation, please read
through all the steps in the procedure before attempting the replacement.
Also, make sure you understand all the precautions in this guide.
Prepare the New Fan Tray
1. Unpack the new fan tray.
2. Inspect the new fan tray to make sure that it is undamaged.
3. Place the new fan tray in a safe, accessible place near the switch, ready for
prompt insertion.
4. You will need a #2 Phillips or cross-head screwdriver.
Remove the Old Fan Tray
1. Loosen the fan tray’s fastening screws.
At the front of the Aruba WLAN 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.
2. 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
CAUTION—This procedure should be performed only by a trained
technician.
CAUTION—Be sure to exercise proper Electrostatic Discharge (ESD) pre-
cautions when handling components.
