Removing and installing a power supply
The server has two power supply bays on the rear panel that accept
hot-swap redundant power supply modules. The system ships out with
at least one power supply module installed.
Power supply redundancy is available if two power supplies are
installed. A redundant power configuration enables a fully-configured
system to continue running even if one power supply module fails.
Determining power supply status
The power supply module has three status LED indicators to display the
power supply status. If the center LED is lit, the power supply needs to
be replaced. For more information on how to determine the power
supply status, refer to “Hot-plug power supply module LED indicators”
section on page 24.
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! The system operating voltage range is 110 to 240
VAC. Do not plug the power cord into an incorrect voltage
source.
