							INSTALLING THE CABINET
Unpacking
Unpack the equipment and check it against your equip-
ment lists. Inspect for physical damage. 
Have the appropriate tools for the job on hand, includ-
ing: a test set, a punch down tool and a digital voltmeter.
Before Installing
Make sure you have a building plan showing the loca-
tion of the common equipment, extensions, the telco
demarcation and earth ground.  In addition, the instal-
lation site must meet the requirements outlined in the
Standard Practices Manual.
Site Requirements
The common equipment is contained in a wall-mounted
cabinet: the Main Cabinet. Choose a central location for
the cabinet that allows enough space for the equipment
Ñ and provides enough room for you to comfortably
work. The Installation Layout (Figure 1-2 on page 1-5)
shows you 
approximatelyhow much space your system
requires.
The common equipment cabinet requires a three-prong
dedicated 117 VAC 60 Hz circuit (NEMA5-15 recep-
tacle) located within 6 feet of the AC receptacle. You
should install the extension block to the right of the
Main Cabinet. Telco should install the RJ11C to the
left of the Main Cabinet.

							INSTALLING THE CABINET
Removing the Cover (Figure 1-1)
To make wall-mounting easier, remove the cover on the
common equipment cabinet. This allows you to use the
cabinet as a mounting template.
1.Unscrew the two captive screws on the lower half of
the cabinet cover.
2.Lift up the lower half of the cover Ñ then slide the
cover back slightly to remove it.
Figure 1-1  REMOVING THE COVER
Mounting the Cabinet (Figure 1-2)
1.Using suitable fasteners, mount a Main Distribution
Frame (MDF) plywood backboard in a centrally
located spot.
2.Hold the Main Cabinet against the MDF and mark
all four mounting holes.
3.Drill the marked holes using a 1/8Ó drill bit.
4.Install two mounting screws (provided) in the top two
holes, leaving about 3/8Ó shank exposed.
5.Hang the Main Cabinet on the top two screws and
fasten in place.
6.Install the bottom two screws and tighten in place.

GROUNDING THE CABINET
Connecting the Ground Wires (Figure 1-3)
The cabinet is grounded at the ETH(Earth Ground)
connection.
1.Loosen the lug on the ground connection.
2.Using a piece of 12 AWG stranded copper wire, con-
nect the ETH to the ground connector.
3.Insert 12 AWG stranded copper wire into the
grounding terminal on the outside of the cabinet.
Firmly tighten the connection.
4.Connect the grounding cable to a known earth
ground.

Now that your cabinet is installed and grounded, go to
Part 2: PCB Installation and Startup. 
DO NOT PLUG IN THE CABINET POWER CORD
WITHOUT FIRST INSTALLING THE PCBS.
