Replacing a ZS3-4 Fan Module
![Caution Caution](graphics/caution.gif) | 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 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.
