Link WTS – Link 3000 MCU
Part Number: 72-0059-01-J.doc Page 18
Expansion shelves cannot be located more than 17 cable feet from the Primary
Shelf.
• All digital interface modules must be within 250 feet of the telephone system.
See your telephone system specifications for distance limitations for analog
modules.
• Location of the Intershelf Junction Panel (JPI300) adjacent to the shelves on a
multi-shelf system.
The Primary Shelf containing the System Controller (CSC or CSO306 or 320)
must be mounted to allow connection to the JPI300 with a five-foot cable.
Expansion Shelves (CSC300 or CSO300) must be mounted to allow connection
of the shelf to the JPI300 using 12 feet or less of cabling.
• Space for the -48V power supply connections. Power supply conduit requires
clearance of 1.5” on the rear or side of the shelves.
• Maximum loop length specifications of the telephone system
• Maximum wire distance from the MCU to a Base Station (6,000 feet)
• Cabling for the Interface Modules and Controller cards. All cables (except
power) are connected to the front face of the cards. Space is provided to route
wiring to the back of the shelf.
Prepare Rack or Wall
The Link 3000 MCU can be mounted in a rack or on the wall. Rack or wall support
must be adequate to support the number of shelves to be installed. Each fully loaded
Link 3000 MCU shelf weighs approximately 35 pounds.
Rack Mounting
Before installing shelves in a rack, be sure the rack is mechanically fastened to the
floor or wall such that it properly supports the number of shelves to be mounted.
Follow the manufacturer’s instructions to prepare the rack.
Be sure to leave 1.5” clearance at the rear of the racks for power conduit.
Wall Mounting
Before wall mounting, cover the wall with 3/4” plywood. Secure the plywood to the
wall studs every 16” with an adequate number of screws to support the number of
shelves to be mounted. Each fully loaded shelf weighs approximately 35 pounds. Be
sure to leave 1.5” clearance on the left side for power conduit.
Using the following drawing as a guide, drill six pilot holes using a 1/8” drill bit.
Insert the six screws (#10 panhead wood screws, 5/8” long) into the pilot holes and
tighten them, leaving approximately 1/8 to 1/4” gap from the wall.
