Replace a 5U fan cooling module

The 5 fan cooling modules (FCMs) provide cooling to storage enclosure modules and components. The fan cooling module
(FCM) has a green and an amber fault LED to identify various states. The asterisk (*) indicates a fault condition.
An important feature of the storage enclosure design is redundancy. The enclosure will maintain continuous operation during
the replacement of a single FCM, if it is within the time limit of 7 minutes, since removal of an FCM significantly reduces airflow
in the storage enclosure.
CAUTION If you remove any FRU while the storage enclosure is powered up, you must replace it with a tested, good
spare within the allotted time for that FRU. If you do not replace the FRU and, when applicable, fully close the related drawer
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 replace a fan cooling module:
1. Retrieve the new FCM in its static-protected container, ready to access and use the new FCM immediately upon removal of
the faulty one.
2. Complete the following actions to remove the faulty FCM:
