Replacing a ZS3-4 Fan Module
 | Caution - Operating a controller for an extended period of time with fans removed reduces the effectiveness of the cooling system. For this reason, the replacement fan should be unpacked in advance and ready to insert into the controller chassis as soon as the faulted fan is removed. |
Fan modules are hot-swappable and can be removed and installed while the storage controller is running without affecting other hardware capabilities. Use the following procedure to replace a ZS3-4 fan module.
-
To flash the locator LED on the chassis to service, go to Maintenance >
Hardware in the BUI and click the associated locator icon
, or go to the service processor (SP) prompt and enter
set /SYS/LOCATE status=on.
-
To locate the faulted component, go to Maintenance > Hardware > Fan
and click the row with an amber indicator.
The component is highlighted in the diagram.
- Extend the controller from the rack as described in Extending the Storage Controller from the Rack.
-
Lift the latch at the top of the fan module to unlock the fan module, and
pull the fan module out.
- Unlock and insert the fan module.
- Apply firm pressure to fully seat the fan module.
- On the replaced fan module, verify that the Fan OK indicator is lit, and that the fault indicator is not lit.
- Verify that the Top Fan status indicator, the Service Required status indicators, and the Locator status indicator/Locator button are not lit.
-
Go to the Maintenance > Hardware screen of the BUI. Click the
right-arrow icon
for the controller and then click Fan to verify that
the online icon 
is green for the newly installed fan module.
- If a fault does not self-clear, see Repairing Active Problems.
