650-W Power Supply Module

The 650-W power supply module specification defines a 1+1 redundant power supply that
supports a dual-processor Intel
power the system: 12VDC and 5VSB. A separate cage (including the power distribution board)
is designed to plug directly to the output connector of the power supply module and provide
additional power converters to produce other required voltages. An IEC connector is provided
on the external face for AC input to the power supply. The power supply contains cooling fans
and meets acoustic requirements.

Mechanical Overview

2.3.1.1
Handle and Retention Mechanism
The power supply has a handle to provide a place to grip the power supply for removal and
insertion. The power supply has a simple retention mechanism to retain the power supply once
it is inserted. This mechanism withstands the specified mechanical shock and vibration
requirements. The tab on the retention mechanism is green to indicate it is a hot-swap touch
point. The latch mechanism is designed in such a way as to prevent inserting the power supply
with the power cord plugged in. This aids the hot swapping procedure: on removal, the power
cord is unplugged first, then the power supply is removed; on insertion, the power supply is
inserted first and then the power cord is plugged in.
The handle protects the operator from any burn hazard.
The plastic handle is molded in the following material:

2.3.1.2
Acoustic and Fan Speed Control Requirements
Sound power levels emitted by the power supply meet the requirements shown in the following
table. Sound power is measured as described in ISO7779. Under a condition where inlet air
temperature exceeds the limit, sound power level may exceed the limit.
The power supply incorporates a variable speed fan. The fan speed varies linearly based on
output loading and ambient temperature. The declared sound power levels (LwAd) of the power
supply unit (PSU) meet the requirements shown in the following table. Sound power is
measured according to ECMA 74 (www.ecma-international.org) and reported according to ISO
9296.
The acoustic measurement of the power supply is performed with the power supply fan
operating at the RPM corresponding to the operating conditions shown in the following table:
