This handle is used for removing or inserting the module into the switch

Fan Status LED

During operation, the Fan Status LED provides the following information:

Slot Labels

When the fan tray is installed in the Aruba WLAN Switch, these labels name

the module slots to the immediate right of the fan tray (see figure above).

Fans (on side)

Three independent fans provide redundancy for cooling the Aruba WLAN

Switch cards.

Three fans are provided in the fan tray. The module is designed to provide for

cooling, even if one fan fails. Any two operating fans will provide enough

airflow for proper cooling until the fan tray can be replaced.

Hot-swapping is supported but should be performed only by a trained

technician. Hot-swapping allows you to replace the fan tray without having to

shut down the system. During the replacement operation, the switch will

continue to function without fans, though the procedure must be completed

within about one minute to resume proper cooling.

CAUTION—Do not use the fan tray handle to lift or move the Aruba

WLAN Switch. Serious damage could result.
