Replacing a ZS3-2 Fan Module

Removing a fan module is a cold-service operation. You must power off the appliance before you remove the fan module. There will be a loss of access to the storage unless the system is in a clustered configuration.

The status of each fan module is represented by a single bi-color LED. The LEDs are located on the motherboard near each fan module, and are visible from the rear panel, by looking through the grille below the risers. Use the following procedure to replace a ZS3-2 fan module.

1. To locate the chassis you want to service, click the associated locator icon on the Maintenance > Hardware screen of the BUI or issue the set /SYS/LOCATE status=on command at the service processor (SP) prompt. The locate LED will flash on the controller chassis.
2. Identify the faulted fan module by locating the corresponding Service Required status indicator or by clicking the locator icon on the Maintenance > Hardware screen of the BUI for the fan you want to replace.
3. Power off the storage controller as described in Powering Off the Controller.
4. Disconnect the AC power cords from the rear panel of the storage controller.

   Caution  -  Because 3.3 VDC standby power is always present in the system, you must unplug the power cords before accessing any cold-serviceable components.
