Install an MDF.
Before installing the common equipment, you should mount a Main Distribution
Frame (MDF) plywood backboard in a centrally located spot. A 1/2 sheet of ply-
wood (4' x 4') should be more than adequate. Mount this backboard using suitable
fasteners, taking care to follow the standard installation practices and local codes.
The equipment cabinet requires a three-prong, dedicated 110 VAC 60 Hz circuit
(NEMA 5-15 receptacle) located within 4 1/2 feet of the AC receptacle.
Normally, you install the extension and trunk blocks to the right of the Main Cab-
inet. Telco should also install the RJ21X to the right of the Main Cabinet.
Local codes may prohibit you from installing extensions, trunks, and optional
equipment in the same blocks.
Do not plug in the 25-pair extension cable with power applied.
Install the cabinet, extension blocks and trunk blocks on the MDF.
Removing the Cover
You must remove the Main Equipment Cabinet cover to get access to the
extension, trunk and auxiliary connections.
1. Slide the cover button to OPEN.
2. Slide the cover away from the Main Equipment Cabinet.
Push button
