The fans in your IBM Netfinity EXP15 are hot swap and redundant.
This means that your IBM Netfinity EXP15 will continue to operate
if a fan fails. It also means that you can remove and replace the fan
while the IBM Netfinity EXP15 is on and accessing drives.

Attention: The fans in your expansion unit pull in fresh air and
force out hot air. These fans are hot swap redundant; however,
when one fan fails, the fan unit needs to be replaced within 48
hours in order to maintain redundancy and optimum cooling.
When replacing the failed unit with the new fan unit, insure that
this operation is performed in less than 10 minutes to prevent any
overheating due to the lack of the additional fans.
Fault LEDs: These amber LEDs are on when a fan fails.
Latches and handles: Use the latches and handles to remove
or install the fans.
