Fan Controls And Indicators - IBM EXP15 Hardware Maintenance Manual

Fan controls and indicators:

Netfinity FAStT EXP500 are hot-swappable and redundant.
This means that your Netfinity FAStT EXP500 will continue
to operate if a fan fails. It also means that you can
remove and replace the fan while the Netfinity FAStT
EXP500 is on and accessing drives.
Attention
The fans in your expansion unit draw in fresh air and
force out hot air. These fans are hot-swappable and
redundant; however, when one fan fails, the fan unit
must be replaced within 48 hours in order to maintain
redundancy and optimum cooling. When you replace
the failed unit, be sure to install the second fan within
10 minutes to prevent any overheating due to the lack
of the additional fan unit.
