Replacing a fan assembly

Before you begin, ensure that you wear an anti-static wrist strap.
Complete the following steps to replace a failed fan assembly. To preserve the
optimal airflow, do not remove a failed fan assembly FRU from the storage
expansion enclosure until you are ready to replace it with a new FRU.
CAUTION:

5 minutes of removal. If replacing it will take longer than 5 minutes, stop all I/O
activity to the storage expansion enclosure and turn off the power until you
complete the replacement.
