3.2 Single Power Supply Module Population
In single power module configurations, server management firmware requires that the power
supply module be populated in the top power module slot. The non-operating slot must have
the power supply blank installed.
Figure 14. Power Supply Blank
Configuring a single power supply module in the bottom location causes the server
management firmware and BIOS to generate a system error during POST and the error is
reported to the System Event Log (SEL).
3.3 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.
3.4 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. The
power supply module can be hot-swapped using the following procedure:
 Extraction: To remove the power supply, unplug the power cord first, and then remove
the power module. This can be done 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.
