WARNING: To reduce the risk of electric shock or damage to the equipment:
• Do not disable the power cord grounding plug. The grounding plug is an important safety
feature.
• Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all
times.
• Unplug the power cord from the power supply to disconnect power to the equipment.
• Do not route the power cord where it can be walked on or pinched by items placed against it.
Pay particular attention to the plug, electrical outlet, and the point where the cord extends from
the equipment.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the power supply or
power supply blank to cool before touching it.
WARNING: To reduce the risk of electric shock or damage to the equipment, do not connect the
power cord to the power supply until the power supply is installed.
CAUTION: Always install either a hot-plug power supply or a power supply blank into each bay
to maintain proper airflow and cooling in the server. Improper airflow can lead to thermal
damage.
Power supply configuration
CAUTION: All power supplies installed in the server must have the same output power capacity
to operate in redundant mode. Verify that all power supplies have the same part number and
label color. When the system detects mismatched power supplies, the system displays POST
messages, does not power on the new power supply, and remains in non-redundant mode.

Installing the redundant hot-plug power supply option
WARNING:
To reduce the risk of personal injury or damage to the equipment, the installation of
power supplies should be performed only by individuals who are qualified in servicing server
equipment and trained to deal with products capable of producing hazardous energy levels.
WARNING:
To reduce the risk of personal injury from hot surfaces, observe the thermal labels on
each power supply or module.
WARNING: To reduce the risk of injury from electric shock hazards, do not open power
supplies. Refer all maintenance, upgrades, and servicing to qualified personnel.
CAUTION: Electrostatic discharge (ESD) can damage electronic components. Be sure that you
are properly grounded (earthed) before beginning any installation procedure.
