3.2.1
Attach Mounting Brackets to the Liebert MPH
Before attaching the horizontal-mount brackets to the Liebert MPH, determine whether to attach the
brackets to the front edge or rear edge of the unit. This will depend, in part, on whether the Liebert
MPH would be best placed in the front of the rack or in the rear for routing power and communication
wires. Bracket location also determines whether the Liebert MPH display is viewed from the front or
rear of the rack.
When mounting the Liebert MPH, position the unit for ease of access and clearance. (Refer to
Table 2
for the dimensions of the Liebert MPH.)
To attach the brackets:
1. Hold one mounting bracket against the side of the Liebert MPH, making sure that the end of the
bracket with the round holes is against the unit.
2. Attach the bracket to the unit with four Phillips head screws, tightening them firmly.
3. Repeat
Steps 1
and
2
for the bracket on the opposite side of the Liebert MPH.

Attach the Liebert MPH to Rack Rails
Determine where the Liebert MPH would be best placed in the rack for routing power and communi-
cation wires.
The rack-mount Liebert MPH is installed horizontally in standard rack face position on the rails
using the square, EIA-spaced holes. They use four captive nuts snapped into the rail holes and four
screws to attach the Liebert MPH brackets to the rail.
As with all Liebert rack-mount equipment, obtain the appropriate size rack-mounting hardware kit
for captive nuts and screws.
