Installing the PDU, PDU+, or Intelligent Switched PDU in the side of a rack

Learn how to install the power distribution unit (PDU), power distribution unit plus (PDU+), or Intelligent Switched PDU horizontally in the side of a rack.

1. Read the Rack safety notices.
2. Identify an open mounting space that is the size of a single EIA in the rack where you are installing the PDU model. Attach the nut clips to the top and bottom holes of the EIA, on each side of the rack. Use the nut clips that were provided with the rack mounting kit.
3. If you are installing a PDU, continue with the next step. Otherwise, for a PDU+, go to step 6. For the Intelligent Switched PDU, go to step 7.
4. Align the PDU with the opening of the rack. Then, while you hold the PDU in place, attach the PDU mounting brackets to the nut clips in the rack with four M6 screws. Use screws that were provided with the rack mounting kit.
5. Go to step 15 for power cord attachment.
6. Align the vertical-mounting brackets (A) to the front of the PDU+ as shown in the following figure. Make sure that you attach the brackets so that the power outlets face the rear of the rack.

7. Attach the brackets (A) to the PDU+ or Intelligent Switched PDU with two M3x5 screws (B) per bracket. Use screws that were provided with the rack mounting kit.
8. If you are installing the PDU or PDU+ long mounting brackets, align the long mounting brackets (A) with the holes in the rear of the PDU, and attach the brackets to the PDU model with two M3 pan-head screws (B) with captive lock washers per bracket. Use screws that were provided with the rack mounting kit.

   If you are installing the Intelligent Switched PDU adjustable mounting rails, complete the following tasks:

   1. Assemble the adjustable mounting rail by using the four screws that are included with the mounting kit.
   2. Attach the adjustable mounting rails to each side of the PDU chassis by using the six screws that are included with the mounting kit.
9. Identify an open mounting space that is the size of a single EIA in the rack where you are installing the PDU model. At the rear of the rack, attach nut clips to the top and bottom holes of the EIA on each side of the rack. Use nut clips that were provided with the rack mounting kit.
   Note: If your rack has square mounting holes, attach cage nuts instead of nut clips to the specified EIA locations. Use cage nuts that were provided with the rack mounting kit.
10. Hold the PDU model at a slight angle and carefully insert it into a mounting space that is a single EIA unit within the rack cabinet. Pushing in slightly on both of the long mounting brackets helps clear the brackets from the rack flanges.
11. Align the end of the PDU model with the short mounting brackets with the outside of the rack flanges. Use two M6 screws (A) if cage nuts are used or M5 screws if nut clips are used per bracket to attach the brackets to the nut clips or cage nuts on the rack flanges. Use screws that were provided with the rack mounting kit.

12. If the side covers are installed, continue with step 13. If you removed the side covers, go to step 14.
13. Secure the long mounting brackets and the blank filler panel (A) to the rack cabinet by completing the following steps:
    1. Adjust the long mounting brackets to fit the depth of the rack cabinet.
    2. Place a mark on both rails at the rear of the PDU, PDU+, or Intelligent Switched PDU.
    3. Remove the two M6 screws (A) if cage nuts are used, or M5 screws that secure the PDU, PDU+, or Intelligent Switched PDU to the rack flanges.
    4. Carefully remove the PDU, PDU+, or Intelligent Switched PDU from the rack frame.
    5. Position the marks on the rails so that they are at the rear of the PDU, PDU+, or Intelligent Switched PDU.
    6. Tighten the M3 pan-head screws that secure the long mounting brackets to the PDU, PDU+, or Intelligent Switched PDU model.
    7. Hold the PDU, PDU+, or Intelligent Switched PDU model at a slight angle and carefully insert it into a mounting space that is a single EIA unit within the rack cabinet. Pushing in slightly on both of the long mounting brackets helps clear the brackets from the rack flanges.
    8. Align the end of the PDU, PDU+, or Intelligent Switched PDU model with the short mounting brackets with the outside of the rack flanges. Ensure that the rails align properly with the front rack flanges. If not, mark and readjust the mounting rails length by removing the PDU, PDU+, or Intelligent Switched PDU and repeating steps 13.b through 13.g. Use two M6 screws (A) if cage nuts are used or M5 screws if nut clips are used per bracket to attach the brackets to the nut clips or cage nuts on the rear rack flanges.
    9. Make sure that the long mounting brackets are aligned with the inside of the rack flanges.
    10. Align the blank filler panel (A) on the outside of the rack flanges, as shown in Figure 7.
    11. Attach the filler panel to the rack flanges and then to the long mounting bracket with one M6 screw (B) per bracket. Use the screws that were provided with the rack mounting kit.
    12. Proceed with step 15.
14. Secure the long mounting brackets and the blank filler panel (A) to the rack cabinet by completing the following steps:
    1. Adjust the long mounting brackets to fit the depth of the rack cabinet.
    2. Tighten the M3 pan-head screws that secure the long mounting brackets to the PDU, PDU+, or Intelligent Switched PDU model.
    3. Make sure that the long mounting brackets are aligned with the inside of the rack flanges.
    4. Align the blank filler panel (A) on the outside of the rack flanges.
    5. Attach the filler panel to the rack flanges and then to the long mounting bracket with one M6 screw (B) per bracket. Use screws that were provided with the rack mounting kit.

15. If the PDU, PDU+, or Intelligent Switched PDU model was provided with a detached power cord, connect the power cord now. Align the connector on the power cord (A) that was provided with the PDU, PDU+, or Intelligent Switched PDU model with the connector on the front of the unit (A), turning as necessary for key alignment. Then, turn the twist-lock (B) on the connector clockwise until it locks into place.
    Attention: Before you connect or disconnect the input power cord from the PDU, PDU+, or Intelligent Switched PDU model, you must disconnect the main input power.

16. Route the power cord from the PDU, PDU+, or Intelligent Switched PDU model toward the rack side braces. Route the power cord along a side brace toward the rear of the rack and secure the power cord with the cable straps that are provided with the PDU, PDU+, or Intelligent Switched PDU.
17. Route the power cord toward a dedicated power source. Use the provided cable straps to secure the power cord along the way. If the power cord must exit the rack to connect to a power source, use the openings in the rack.
    Attention: To prevent damage to a power device and other connected devices, always connect the power device to an authorized power source for that device.
18. Connect the power cord to a properly wired and grounded dedicated power source. Then, you can connect the servers or rack PDU, PDU+, or Intelligent Switched PDU in the rack to the power outlets on the PDU, PDU+, or Intelligent Switched PDU model.
19. Route all of the other power cables neatly, and secure the power cables with cable straps.
20. If the side covers or doors were removed, reinstall them.
