2.2 Single Power Supply Module Population
In single power module configurations, server management firmware requires that power supply
module #1 be populated. The power module #1 slot is located closest to the baseboard away
from the side edge of the chassis. See the diagram below. The non-operating slot must have
the power supply blank installed.
Configuring a single power supply module in the #2 module slot will cause the server
management firmware and BIOS to generate a system error during POST and to the System
Event Log and will cause the System Status LED on the control panel to blink green, denoting a
degraded system configuration.
2.3 Handle and Retention Mechanism
Each power supply module includes a handle allowing 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 will withstand 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 in such a way,
