4.2 Fan Alarm: Fan Removal and Replacement
The embedded alarm board monitors temperature & fan status. Should a fan
become disabled, the Alarm LED will light up and an audible warning will be
heard. The LED corresponding to the faulty fan will flash, indicating which fan
needs to be replaced.
To disable the audible warning, press the Alarm RST button. The Alarm LED
will continue to flash until the faulty fan is replaced.
Fan Removal and Installation Procedure (cPCI PSU models)
1. Remove the screws attaching the front filter cover at the base of the
chassis (2 screws) and remove the cover (see Air Filter Removal
and Replacement Procedure above).
2. Pull the faulty fan module out of the fan tray and replace with a
functional fan.
3. Reverse steps 1-2 to replace the filter cover.
For replacement fan modules, please contact your ADLINK distributor.
