• “System equipment, supplies, and tools” on page 89
General requirements
Before you install the BCM main unit or expansion unit, complete the following actions:
• Determine the location for the BCM main unit (or expansion unit), telephones, and other
equipment based on spacing and electrical requirements.
• Order the required trunks from the central office.
• Ensure that you have all the equipment and supplies you need to install the system.
Environmental requirements
Ensure you meet the installation environmental requirements. The installation area must be:

equipment that produces electromagnetic, radio frequency, and electrostatic interference
• within 1.5 m (5 ft.) of a three-wire grounded electrical outlet
• clean, free of traffic and excess dust, dry, and well ventilated
• within the temperature ranges of 10°C and 40°C (50°F and 104°F)
• between 20% and 80% non-condensing relative humidity
• structurally strong enough and with enough space to support the BCM units
• a minimum of 46 cm (18 in.) from the floor
Note: The installation area must be of sufficient height from the floor to prevent water
