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:

1Feed the AC power and ground wire through the wire manager (refer to Figure 2-7).

2Open the ferrite cores by unsnapping the plastic case.

3Attach a ferrite core around the AC power cord and the ground wire by snapping the plastic case shut.

4Attach the second ferrite core adjacent to the first ferrite core by repeating Steps 2 and 3.

5Slide the ferrite cores between the wire manager and the power supply module (refer to Figure 2-7).

6Attach the ground wire to the grounding screw on the power supply module.

7Check that the other end of the ground wire is connected to the terminals of the single-point ground baron the AC outlet box.
