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 for a DSX-80 4-Slot
KSU. A full sheet of plywood (8’ x 4’) should be adequate for a DSX160 cabinet. Be sure to mount the back-
board using suitable fasteners, taking care to adhere to standard installation practices and local codes. See
Fig-
ure 1: Installation Layout, DSX-80
below and
Figure 2: Installation Layout, DSX-160
(page 23) for more.
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
.

Local codes may prohibit you from installing extensions,
