Prepare the New Fan Tray
1
Unpack the new 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.
2
Disengage the fan tray.
Grasp the module handle firmly and draw the fan tray forward from its slot.

removing the fan tray.
Also, when hot swapping, once the fans stop spinning, the Alcatel

limited time (approximately one minute) before installation of the new
fan tray must be completed.
3
Fully remove the fan tray and place it safely aside.
Once disengaged, the fan tray should easily slide out of the switch chassis.
