Handle and Retention Mechanism
Each power supply module includes a handle for module insertion to or removal from the
module enclosure. Each module has a simple retention mechanism to hold the power module in
place once it is inserted. This mechanism withstands the specified platform mechanical shock
and vibration requirements. The tab on the retention mechanism is colored green to indicate it
is a hot-swap touch point. The latch mechanism is designed to prevent insertion or removal of
the module when the power cord is plugged in. This aids the hot-swapping procedure.

Hot-swap Support
Hot-swapping a power supply module is the process of extracting and re-inserting a power
supply module from an operating power system. During this process, the output voltages
remain within specified limits. Up to two power supply modules may be on a single AC line. You
can hot-swap the power supply module using the following procedure:
Extraction: To remove the power supply, unplug the power cord first, and then remove
the power module. You can do this in standby mode or power-on mode.
Insertion: Insert the module first and then plug in the power cord. If the system is
powered off, the system and the power supply will power on into standby mode or
power-on mode.

Airflow
Each power supply module incorporates two non-redundant 40-mm fans for self-cooling and
partial system cooling. The fans provide at least 10 CFM airflow through the power supply when
installed in the system and operating at maximum fan speed. The cooling air enters the power
module from the PDB side (pre-heated air from the system).
