Model 2200 Cabinet Mounting Information
Make sure that the Model 2200 is disconnected from its power source. Remove the front
door, top cover and bottom cover to reveal the eight 1/4" diameter mounting holes in the
back panel along the left and right sides of the cabinet. These holes are used for wall
mounting, using wall anchors or lag bolts. See Figure 8.
Wall mounting to a 3/4" plywood backboard (like PABX equipment) is the most common
installation method. Eight rubber grommets have been supplied to use as spacers between
the Model 2200 rear-panel mounting holes and the plywood mounting surface.
Model 2100 Cabinet Mounting Information
The Model 2100 can be wall mounted like PABX equipment or rack mounted like radio
equipment using the Zetron mounting kit (P/N 950-9128). The mounting kit contains
hardware and brackets that bolt to the Model 2100 left and right side panels. Placing the
brackets toward the rear of the cabinet gives 1/4" clearance from the surface of a wall
(such as 3/4" plywood). Placing the brackets toward the front of the cabinet gives you easy
mounting access for standard 19" equipment rack. The Model 2100 requires 12 Units of
vertical rack space (20") but only 5.5" of mounting depth.
Cable Routing
Telephone trunk, radio, and power connections are brought through the right side on the
Model 2200 and the bottom rear on the Model 2100, when rack mounted using 50
conductor cables with FEMALE connectors. The 50-pin mating connectors are mounted
on the backplane circuit boards, visible below the circuit card cage after the unit's front
door has been removed. See Figure 9.
To ground the cabinet chassis to a common earth connection, use any of the screws
holding the backplane to the rear panel, or any of the nuts holding the side panels to the
power supply shelf.
Caution! There are no internal protection devices for lightning strikes;
use external protection devices, such as those available from
Zetron to protect your equipment investment.
