Installing the 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 4 slot cabinet (see
Figure 1-1 4 Slot Cabinet Installation Layout below). A full sheet of plywood (8' x 4') should be adequate for
an 8 slot cabinet (see Figure 1-2 8 Slot Cabinet Installation Layout on page 1-5). Be sure to mount the back-
board using suitable fasteners, taking care to adhere to standard installation practices and local codes.
The equipment cabinet requires a three-prong, dedicated 110 VAC 60 Hz circuit (NEMA 5-15 receptacle).
The AC receptacle must be within 7' feet of the cabinet's lower left corner.
Normally, you install the extension and trunk blocks to the right of the cabinet. Telco should also install the
RJ21X to the right of the cabinet.
