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 0º– 
40º C (31º–104º F). Optimal temperature is 20º C (68º F). Humidity 
recommendation is 20%– 80% (non-condensing).
