5.5. Cooling Module Maintenance
5.5.1 Notes on Cooling Module Maintenance
ƒ Two redundant cooling modules: The subsystem is equipped with two
redundant, hot swappable, dual-fan cooling modules located above the PSU
modules. These cooling modules control the internal operating temperature
of the subsystem and therefore their working integrity should be maintained
at all times.
ƒ Detecting a failed cooling fan module: If a cooling module fails, you can
choose to be notified of the failure by the LEDs located at the back of the
module, an audible alarm, the firmware terminal access, the RAIDWatch
Panel View, or the various event notification methods.
Shown below are the locations of cooling fans:

NOTE:
To reduce the risk of system down time, replace a cooling fan/PSU module
even when only one cooling fan fails within. Replacing a single cooling fan
within each module may take several minutes and is not an operation
completed at the installation site.
