Installing or Replacing a 3-kW AC Power Supply
d) Slide the guide bracket that is located on the top of the power supply into the track at the top of the power supply
slot. Slide the power supply all the way into the slot.
The front of the power supply is about 0.25 inches (0.6 cm) outside the chassis.
e) Slide the handle on the middle of the power supply ejector handle about 0.25 inches (0.6 cm) and rotate the lever
away from the front of the power supply. Do this while pushing the power supply all the way into the chassis. See
the following figure.
1
Slide and hold the middle handle on the ejector lever
toward the end of the lever.
2
Fully rotate the release lever away from the front of
the module.
3
Slide the power supply into the open power supply
slot in the chassis until it stops. The front of the
module is about 0.25 inches (0.6 cm) in front of the
chassis.
f) Rotate the ejector lever toward the front of the power supply and be sure that the other end of the lever locks into the
chassis.
The lever will click when you rotate it all the way to the front of the power supply. Be sure that the power supply is
fully inserted into the slot. The front of the power supply will be even with the surface of the chassis.
g) Attach the power cable to the power receptacle on the power supply and rotate the power cable holder onto the plug
on the cable.
h) Make sure that the other end of the power cable is attached to the AC power source in one of the following ways:
• If you are using the combined power mode or the n+1 redundancy mode, you can connect the power cable to
as few or as many power sources/grids as you like.
• If you are using the n+n redundancy mode, you must connect the power cable to the same power source as used
by the other power supplies in the same set of power supply slots in the chassis. The power cables for slots 1
through 4 must be connected to one power source and the power cables inslots 5 through 8 must be connected
to another power source.
