Redundant hot-plug power supply
The server supports a second hot-plug power supply to provide redundant power
to the server in the event of a failure in the primary power supply. You can install
or replace a second hot-plug power supply without powering down the server.
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 server.
CAUTION: If only one power supply is installed, do not remove the
power supply unless the server has been powered down. Removing the
only operational power supply will cause an immediate power loss.
NOTE: If you remove or replace the primary hot-plug power
supply, use the T-15 Torx screwdriver provided with the server to
remove the shipping screw. It is located just under the port-colored
plastic handle of the power supply unit.
