Determine Location of MCU
Each MCU is approximately 2.75” wide, 12.5” high, and 7” deep, and
weighs about 5 pounds. The unit is designed to be wall-mounted over
3/4” plywood.
• Select a location for the MCU with sufficient backboard space and
an available outlet.
• The MCU must be within 2,200 feet of the Base Stations.
• All digital interface modules must be within 250 feet of the
telephone system.
• See your telephone system specifications for distance limitations
for analog modules.
• Since the front panel is used for cabling and as an operator’s
console, mount the units so the front panel is accessible.
If your system has more than one MCU, the units should be mounted
vertically, side by side, physically touching the adjacent unit. Do not
stack units on top of one another. Stacked MCUs can cause
overheating and failure.
Polycom recommends an operational temperature range of 0
º– 40º C
(31
º–104º F). Optimal temperature is 20º C (68º F). Humidity
recommendation is 20%– 80% (non-condensing).
