Installing and removing the power
supply
The server has a single 720-Watt power supply, capable of operating at
100 - 240 input volts.
WARNING! To reduce the risk of personal injury or damage to the
equipment, the installation of power supply modules should be
referred to individuals who are qualified to service server systems
and are trained to deal with equipment capable of generating
hazardous energy levels.
WARNING! To reduce the risk of personal injury from hot surfaces,
observe the thermal labels on each power supply module. You can
also consider wearing protective gloves.
WARNING! To reduce the risk of personal injury from electric
shock hazards, do not open the power supply modules. There are
no serviceable parts inside the module.
Caution! Electrostatic discharge can damage electronic
components. Make sure that you are properly grounded before
handling a power supply module.
Caution! Due to chassis airflow disruption, a power supply bay
should never be vacant for more than two minutes when the server
is powered on. Exceeding five minutes might cause the system to
exceed the maximum acceptable temperature and possibly
damage the system components.
Caution! The power supply is only hot-pluggable if you have a
redundant system with two power supplies installed. If you only
have one power supply installed, before removing or replacing the
power supply, you must first take the server out of service, turn off
all peripheral devices connected to the system, turn off the system
by pressing the power button, and unplug the AC power cord from
the system or wall outlet.
