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.
-
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.
-
Power off the storage controller as described in Powering Off the Controller.
-
Disconnect the AC power cords from the rear panel of the storage
controller.

-
Remove the top cover as described in Removing the Controller Top Cover.

Press the fan module down until it clicks securely in the fan tray.
-
Replace the top cover on the chassis, and tighten the two captive screws
at the back of the top cover.

Return the controller to the normal rack position by pushing the release
tabs on the side of each rail while slowly pushing the storage controller
into the rack.

Connect the power cords to the power supplies. Verify that standby power
is on, indicated by the Power/OK and SP status indicators flashing green on
the front panel.
-
Verify that the SP status and Power/OK indicators go solid green after the
boot.

Verify that the Fan indicator and the Service Action Required indicator on
the front panel are not lit.

Go to the Maintenance > Hardware screen of the BUI. Click the
right-arrow icon for the controller, click Fan, and verify that the status
