Unpacking
Unpack the equipment and check it against your equipment lists.
Inspect for physical damage. If you are not sure about a compo-
nent’s function, review the Product Description Manual. Contact
your Sales Representative if you have additional questions.
Have the appropriate tools for the job on hand, including: a test
set, a punch down tool and a digital voltmeter.
Before Installing
Make sure you have a building plan showing the location of
the common equipment, extensions, the telco demarcation and
earth ground.  In addition, the installation site must meet the
requirements outlined in the Standard Practices Manual.
Site Requirements
The common equipment is contained in the wall-mounted Main
Equipment Cabinet. Choose a central location for the cabinet
that allows enough space for the equipment — and provides
enough room for you to comfortably work. The Installation
Layout (Figures 1-1 and 1-2) shows you abouthow much space
your system requires.

Planning the Installation for a 4 Slot Main
Equipment Cabinet (Figure 1-1)
Before installing the common equipment, you should mount a
Main Distribution Frame (MDF) plywood backboard in a cen-
trally located spot. A 1/2 sheet of plywood (4’ x 4’) should be
more than adequate. Mount this backboard using suitable fas-
teners, 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) located within 7
feet of the AC receptacle.
Normally, you install the extension and trunk blocks to the right
of the Main Cabinet. Telco should also install the RJ21X to the
right of the Main Cabinet.

Planning the Installation for an 8 Slot Main
Equipment Cabinet (Figure 1-2)
Before installing the common equipment, you should mount a
Main Distribution Frame (MDF) plywood backboard in a cen-
trally located spot. A full sheet of plywood (8’ x 4’) should be
more than adequate. Mount this backboard using suitable fas-
teners, 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) located within 7
feet of the AC receptacle.
Normally, you install the extension and trunk blocks to the right
of the Main Cabinet. Telco should also install the RJ21X to the

Unpacking the Wall Mount Bracket(Figure 1-4)
The wall mount bracket and screws are taped to the packing mater-
ial in the Main Equipment Cabinet box. Unpack the wall mount
bracket and mounting screws.

Mounting the Wall Mount Bracket(Figure 1-5)
Mount the wall mount bracket on the MDF in a convenient loca-
tion, about 12” higher than where you want the bottom of the cabi-
net to line up.
