Replace a controller fan module

The two (2) controller fan modules provide cooling to the auxiliary bay of the storage enclosure.
An important feature of the storage enclosure design is redundancy. The enclosure will maintain continuous operation
during the replacement of a single controller fan module, as long as it is within the time limit of eight (8) minutes, since
removal of a controller fan module significantly reduces airflow in the auxiliary bay.
CAUTION If you remove any FRU while the storage enclosure is powered up, you must replace it with a known
good spare within the allotted time for that FRU. If you do not replace the FRU and, when applicable, close the related
cover within the identified time limit, you void the product warranty and the storage enclosure might overheat, causing
equipment failure and possible data loss.
CAUTION Do not remove covers from any FRU. There is a danger of electric shock inside. Return the FRU to your
supplier for repair.
To remove and replace a controller fan module:
1. If you plan on removing all controller fan modules, properly shut down the storage enclosure.
2. Retrieve the new controller fan module in its static-protected container, ready to access and use the new controller
fan module upon removal of the faulty one.
3. (Optional) As an extra safety measure while installing disk drives, support the storage enclosure with a mechanical
lift to avoid any potential issues caused by downward forces.
4. Facing the front of the rack cabinet, loosen the storage enclosure chassis flanges by twisting the top captive
thumbscrew on each side of the storage enclosure to the left.
5. Lower the pull handles, then steadily pull the storage enclosure out on its rails until it locks in the service position.
6. Locate the auxiliary bay cover's front latch, release it by pressing the latch in to release the cover, then lift the cover
away and set it aside.
7. Locate the release latch of the failing controller fan module, which is toward the inside of the auxiliary bay.
8. Press the tab gently toward the chassis sidewall to release the latch, then pull steadily upward to disengage the fan
from the baseplane.
9. Gently remove the controller fan module from the storage enclosure and set aside.
