module into place. Doing so can damage the back-end connectors or
enclosure backplane.
Secure the PSU into the chassis slot. While at it, make sure the
squared notches of the retention handle lock onto the metal groove on
the interior sides of the module slot. Once in place, pull the retention
handle in an upward motion to secure the module.
Step 6. Insert and fasten the retention screw underneath the handle to secure
the module.
Step 7. Install the cable clamp assembly (if used).
5.5. Cooling Module Maintenance
5.5.1 Notes on Cooling Module Maintenance
 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.
 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.
 Replacing a cooling module: When you are notified that a cooling module has
failed, it should be replaced as soon as possible. A failed cooling module should only
be removed from the subsystem when you have a replacement module that can be
installed as soon as the failed cooling module has been removed.
WARNING!
Although the cooling fan modules are fully redundant, it is not advisable to run the
Falcon subsystem with a single cooling module for a long period of time. If the
second cooling module fails, the system is at risk of sustaining irreparable damage.
