Securing 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.

Secure the PDUs in the Rack

Before You Begin

For this procedure, you will need:

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

    See Power the Rack Off for power-off instructions.

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

    Refer to the equipment documentation for instructions.

  3. 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 (see Securing a PDU to the Mounting Brackets Using Shipping Screws).

    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.

  4. Insert two spring nuts into each rear rack frame groove (see Installing Spring Nuts Into Rack Frame).

    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).


    Figure 5-2 Installing Spring Nuts Into Rack Frame

    image:Figure showing how to install the spring nuts into the rack frame.
  5. 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.

  6. Using a T-25 Torx wrench key, secure the two PDU shipping brackets to the rack by tightening the screws into the spring nuts (see Securing the Standard PDU Power Input Lead Cords and Securing the Compact PDU Power Input Lead Cords).

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

    Figure 5-4 Securing the Compact PDU Power Input Lead Cords

    image:Figure showing how to secure the compact PDU power input lead cords to the shipping brackets.
  7. Using tie-wraps, secure the PDU power lead cords to the shipping brackets (see Securing the Standard PDU Power Input Lead Cords and Securing the Compact PDU Power Input Lead Cords).

    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.

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