Power Sub-system
4.1.1.1 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 aid in 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. You can use a metal handle only if the
temperature remains less than 55 degrees when running at maximum load under maximum
ambient temperature conditions.
A plastic handle is molded from the following material:

4.1.1.2 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.
The PSU acoustic test report should include at a minimum the following information: power
supply dimensions, picture, fan model and size, fan voltage (or duty cycle), and RPM and PSU
sound power level at each operating condition. The proper RPM thermally sustainable is
determined through PSU thermal testing and should be submitted as an appendix to the
acoustic test report.
The cage should be tested in a 1+0 non-redundant configuration and a 1+1 redundant
configuration.
