5. Using a 9/16-inch socket and socket extensions, disconnect the
input-power wiring that terminates on the ground lugs and terminal

6. Disconnect the output-power wiring harness and remove all clamps
that secure the power cables to the frame. Include the following:
Each power supply
The control assembly for the –48 Vdc
The power-control assembly
The power-shutdown cable near the bottom of the shelf
7. From the front of the cabinet, remove the two mounting screws on the
assembly front, as shown in Figure 8-21. Set the screws aside in a safe
place.
8. Refer to Figure 8-21 and slide the assembly out the back of the cabinet.
Performing this step requires two people because of the weight of the
power-distribution assembly. Make sure that all power supplies are
disconnected from the output wiring harness, so the harness can be
pulled through the wire channel in the shelf.
9. Insert the replacement power-distribution assembly into the power-
distribution shelf (Figure 8-21). Performing this step requires two people
because of the weight of the power-distribution assembly.
10. Insert the two screws, removed in step 7, into the front of the
assembly and into the frame.
