Installing the PDU or PDU+ in the side of a rack with ECL0

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

1. Read the Rack safety notices.
2. Choose one of the following options to install your PDU model:
   • To install the PDU, go to step 5.
   • To install the PDU+, continue with step 3.
3. 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.

4. Attach the brackets (A) to the PDU+ with two M3x5 screws (B) per bracket. Use screws that were provided with the rack mounting kit.
5. Align the long mounting brackets (A) with the holes in the rear of the PDU model, 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.

6. Identify an open mounting space that is the size of a single EIA in the rack where you will install 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.
7. Hold the PDU model at a slight angle and carefully insert it into a mounting space that is a single EIA in height 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 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.

9. 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 (A) to fit the depth of the rack cabinet.
   2. Tighten the M3 pan-head screws (D) that secure the long mounting brackets to the 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 (B) 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 (C) per bracket. Use screws that were provided with the rack mounting kit.
10. If the 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 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: You must disconnect the main input power before connecting or disconnecting the input power cord from the PDU model.

11. Route the power cord from the PDU model toward the rack side braces. Then, route the power cord along a side brace toward the back of the rack and secure the power cord with the cable straps that are provided with the PDU model.
12. Route the power cord toward a dedicated power source. Use the provided cable straps to secure the power cord along the way. Use the openings in the rack if the power cord must exit the rack to connect to a power source.
    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.
13. Connect the power cord to a properly wired and grounded dedicated power source. Then, you can connect the servers or rack PDUs in the rack to the power outlets on the PDU model.
14. Route all of the other power cables neatly, and secure the power cables with cable straps.
