Installing the Power Supply
Installing the Power Supply Module
in the Carrier
1 Lower the power supply module hook onto the rod on top of the carrier.
2 Make sure the connector on the module mates properly with the
connector on the carrier.
3 Push the module into the carrier until it locks into place.
Installing the Ferrite Cores
At this point, the power supply should have been installed in the carrier, but
there should be no cables or power cords attached to the power supply
module.
NOTE:
If you are upgrading a system, unplug the AC power cord and remove the
ground wire attached to the grounding screw on the front of the power supply.
Follow these steps to install the ferrite cores:
1 Feed the AC power and ground wire through the wire manager (refer to
Figure 2-7).
2 Open the ferrite cores by unsnapping the plastic case.
3 Attach a ferrite core around the AC power cord and the ground wire by
snapping the plastic case shut.
4 Attach the second ferrite core adjacent to the first ferrite core by
repeating Steps 2 and 3.
Slide the ferrite cores between the wire manager and the power supply
5
module (refer to Figure 2-7).
Attach the ground wire to the grounding screw on the power supply
6
module.
7 Check that the other end of the ground wire is connected to the terminals
of the single-point ground baron the AC outlet box.
