Installation

Preparing for Installation

Before installing the rPDUs in a rack enclosure, consider location and orientation. For most installations, the

selected location and orientation depends on the number of rPDUs that will be installed and the cable

management plan.

For example, suppose you plan to separate data and power cables on opposite sides of the rack enclosure. For this

configuration, install one or two rPDUs in the same tray. Route the data cables to the other rPDU tray (serving

as a cable channel) on the opposite side of the rack enclosure.

Another plan might be to balance the data and power cables on each side. For this configuration, install one

rPDU on each side of the rack enclosure. The remaining portion of each rPDU tray serves as a cable channel for

bundled and properly dressed data cables running beside the rPDU.

Other considerations include the orientation of the rPDU and the type of strain relief brackets mounted on the

rPDUs.

Installing Hardware for Options

Install the hardware that supports installation options before installing the rPDUs in the rack enclosure. This

includes the following:

S Strain relief brackets for cord management (optional kit)

S Deep mounting pegs for the 90° mounting option (supplied)

NOTE:

The factory-installed standard mounting pegs are secured to the chassis by two 8-32 3/7” mounting screws. The

user-installed deep mounting pegs are secured to the chassis by two 8-32 5/8” mounting screws.

Installing Strain Relief Brackets

To install the optional strain relief brackets:

1 Place the rPDU on a flat, stable surface.

2 Align the screw mounting holes on the rPDU with the screw mounting holes on the bracket (see Figure 6).

3 Secure the bracket with the supplied screws.

4 Are you installing deep mounting pegs for 90° installation?

If no, go to “Installing the rPDU in the Rack Enclosure” on page 19.

If yes, continue to the next section, “Installing Deep Mounting Pegs” on page 18.
