Environmental Manager: Main Module 5
Installation—Main Module
You can install the Main Module in the front or the
rear of the rack or enclosure, using either the
rack-mount option, which uses 1 U of rack space, or
the toolless peg-mount option, which does not use
any U-spaces. (The toolless peg-mount option is
available only with APC NetShelter® VX and SX
racks and enclosures).
Toolless peg-mount installation
1. Slide both mounting pegs into the holes
located in the cable cha nnel in the rear panel
of the rack.
2. Snap the Main Module into place by pushing it
downward until it locks into position.
Rack-mount installation
1. Remove the toolless mounting pegs located at
the front of th e unit.
2. Attach the brackets (provided) to each end of
the Main Module, using two screws for each
bracket.
3. Choose a location in the rack for the Main
Module.

Note: The Main Module

occupies one U-space. A notched
hole (or a number, on newer racks)
on the rack’s vertical rail denotes
the middle of a U-space.
