Learn how to install the power distribution unit (PDU) or power distribution unit plus (PDU+) horizontally
in the side of a rack.
Tip: Removing the rack doors and side panels might
make installation easier.
To install the PDU model
in a single EIA horizontal mounting space in the rack, complete the
following steps:
- Read the Rack safety notices.
- 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.
- 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.
Figure 5. Aligning the vertical-mounting brackets to the front
of the PDU+
- Attach the brackets (A) to the PDU+ with two M3x5
screws (B) per bracket. Use screws that were
provided with the rack mounting kit.
- 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.
Figure 6. Attaching the
long mounting brackets
- 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.
- 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.
- 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.

the rack
- Secure the long mounting brackets and the blank filler
panel (A) to the rack cabinet by completing
the following steps:
Figure 8. Attaching the brackets
and filler panel to the rack
- Adjust the long mounting brackets (A) to
fit the depth of the rack cabinet.
- Tighten the M3 pan-head screws (D) that
secure the long mounting brackets to the PDU model.
- Make sure that the long mounting brackets are aligned with the
inside of the rack flanges.
- Align the blank filler panel (B) on the
outside of the rack flanges.
- 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.
- 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.
Figure 9. Aligning the connector on the power cord with the PDU model
- 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.
- 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.
- 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.
- Route all of the other power cables neatly, and secure
the power cables with cable straps.
