Replacing a ZS5-2 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. Use the following procedure to replace a ZS5-2 fan module.

1. Identify the faulted fan module.

   • If you are not physically at the system, go to the Maintenance > Hardware section of the BUI, click the right-arrow icon for the controller, click Fan, and note the ID of the faulted fan module, which has an amber icon. To highlight the location of the fan module in the controller picture, click on the fan module ID. To view details about the faulted fan module, click its information icon and then click Active Problems.

   • If you are physically at the system, note that each fan module has a fan fault LED that is located near the module on the motherboard. The amber LED is illuminated for failed fan modules.

2. Power off the storage controller as described in Powering Off the Controller.
3. 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.
