SpectraLink 150 M3 MCU manual Site Preparation, Required Materials, Determine Location of MCU

SpectraLink Corporation Link WTS Installation and Operation

3. Site Preparation

3.1Required Materials

The following equipment must be provided by the customer.

1.Outlet Strip – Recommended for installations with more than one MCU. This will allow the MCUs to be turned on and off together.

2.Cross-Connect Block – required to connect the telephone switch ports and the Base Stations to the MCU.

3.25 Pair Cables – RJ-21 male at MCU end, required to connect the MCU to the cross-connect blocks.

4.Backboard space – the MCU is designed to be wall mounted to ¾” plywood securely screwed to the wall.

5.Quick Clip Fuse – Required with an RCO410 Outdoor Base Station or when a Base Station is located in a separate building from the Link 150 M3 MCU. Recommended Quick Clip Fuse is available from Illinois Tool Works, Linx Division, Model # SCP-2X2.

6.Base Station Mounting Hardware – If the Base Stations will be mounted on finished walls or ceilings, a 4-5" long ¼" bolt, nuts, and washers will be required for each Base Station mounted.

3.2Determine Location of MCU

Each MCU is approximately 2.75 inches wide, 12.5 inches high, and 7 inches deep, and weighs about 5 pounds. The unit is designed to be wall mounted over ¾”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.

!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.If your system has more than one MCU, the units should be mounted
