Grasp the handle of the new power supply and gently
slide it into the chassis.

To seat the power supply, ensure that all connectors
are aligned. Then push the power supply inward until
the connectors engage and latch. The latch should
slide up. You feel a slight resistance as the connectors
engage.
CAUTION: If the resistance is too great, the
connectors may not be aligned. Forcing the power
supply inward could damage the connectors. If
necessary, remove and reinsert the power supply,
ensuring that the connectors are properly aligned.
6
Tighten the captive screws that secure the power
supply to the chassis.
7
Plug the power cord into the system.
8
Plug the other end of the power cord into the
building’s power outlet.
If your system has two power supplies, be sure to
plug in the second power supply. Leaving the second
power supply unplugged causes the system
diagnostics to generate a power supply error.
