Installing the Main Equipment Cabinet

Installing the Main Equipment Cabinet

Planning the Installation

Before installing the common equipment, you should mount a Main Distribution Frame (MDF) plywood back-
board in a centrally located spot. A 1/2 sheet of plywood (4' x 4') should be adequate. Be sure to mount the
backboard using suitable fasteners, taking care to adhere to standard installation practices and local codes. See
Figure 1: Installation Layout, DSX-40 below.
The Main Equipment Cabinet requires a three-prong, dedicated 110 VAC 60 Hz circuit (NEMA 5-15 recep-
tacle). The AC receptacle must be within 7 feet of the cabinet's lower left corner.
Normally, you install the extension and line blocks to the right of the cabinet. Telco should also install the
RJ21X to the right of the cabinet
.
