Replacing an Oracle ZFS Storage 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 an Oracle ZFS Storage ZS3-2 fan module.

1. To flash the locator LED on the chassis to service, from the Maintenance BUI menu, select Hardware, and click the associated locator icon , or go to the service processor (SP) prompt and enter set /SYS/LOCATE status=on.
2. To locate the faulted component, from the Maintenance BUI menu, select Hardware, then select Fan, and click the row with an amber indicator.

   The component is highlighted in the diagram.

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