Secure the PDUs in the Rack

Prior to shipping a rack, you must first secure the PDUs, the power lead cords, and any installed equipment inside the rack.

1. Gather the required tools.

   For this procedure, you need:

   • T-25 Torx wrench key

   • PDU shipping brackets

   • Spring nuts and M5 screws for the PDU shipping brackets

   • Tie-wraps

   • (Standard PDUs only) Four M5 standard PDU mounting bracket shipping screws and four washers

2. Power off the rack and disconnect the PDU power lead cords from the building's AC power source.

   See Power Off the Rack for power-off instructions.

3. Open the rear door and, if necessary, secure any installed equipment and equipment cables inside the rack.

   Refer to the equipment documentation for instructions.

4. If your rack contains standard PDUs, use a T-25 wrench key to secure the PDUs to the mounting brackets using two M5 shipping screws and two washers per mounting bracket.

   If your rack contains standard PDUs that were installed at the factory, the PDUs might already be secured to the mounting brackets with shipping screws and washers.

   
   
5. Insert two spring nuts into each rear rack frame groove.

   Insert the spring nuts into the frame groove at 45-degree angles. Secure the PDU shipping brackets to these spring nuts (two spring nuts per bracket).

   
   
6. Move the spring nuts up or down the rack frame groove to the desired location.

   Install one PDU shipping bracket near the top of the rack and the other near the bottom of the rack.

7. Using a T-25 Torx wrench key, secure the two PDU shipping brackets to the rack by tightening the screws into the spring nuts.

   Secure each PDU shipping bracket to the rack frame using two screws, one per side.

   • The first figure shows how to secure the standard PDU power input lead cords.

   • The second figure shows how to secure the compact PDU power input lead cords.

   
   
   
8. Using tie-wraps, secure the PDU power lead cords to the shipping brackets (see the figures in step 2).

   Use the top shipping bracket to support the weight of the power lead cords, and place the power connectors behind the bottom bracket. Tighten all tie-wraps firmly to ensure that the power lead cords do not become loose when the rack is shipped.

9. After securing the power lead cords, close the rack doors.
