Installation Preparation Checklist
This section provides information you need to know before you install the Business
Communications Manager and contains the following information:
• “Environment Checklist” on page 102
• “Electrical Requirements” on page 103
• “Internal wiring requirements” on page 103
Before you install the base BCM platform base or expansion unit hardware, complete the
following actions.
• Determine the location for the Business Communications Manager base unit (or expansion
unit), telephones, and other equipment based on spacing and electrical requirements. For more
information about spacing and electrical requirements, refer to the “Environment Checklist”
on page 102 and the “Electrical Requirements” on page 103.
• Order the required trunks from the central office.
• Check that all of the media bay modules are installed in the Business Communications
Manager base unit or expansion unit.
• Ensure that you have all the equipment and supplies you require to install the system.
Environment Checklist
The installation area must be:
• minimum of 4 m (13 ft) from equipment such as photocopiers, electrical motors, and other
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 95°F)
• between 20% and 80% non-condensing relative humidity
• enough space and strength to support the Business Communications Manager
• minimum of 46 cm (18 in.) from the floor
Note: The installation area must be of sufficient height from the floor to prevent water
damage.

Electrical Requirements
The following electrical requirements must be met:
• Power must be supplied from a non-switched, unobstructed outlet within 1.5 m (5 ft.) of the
Business Communications Manager base unit or expansion unit.
• The supplied power must be a dedicated 110 V to 120 V ac nominal (or 220 V to 230 V ac
nominal), 50/60 Hz, 15 A minimum service with a third wire safety ground. The third wire
safety ground provides shock protection and avoids electromagnetic interference.
The Business Communications Manager (or expansion unit) power cord is 1.5 m (5 ft) long. You
can connect the power cord to a power bar with a maximum length of 2 m (6.5 ft), including power
bar. You must use a power bar approved by an appropriate National Test Body, with a third wire
ground. Do not use an extension cord between the platform base chassis and the power bar, or
between the power bar and the electrical outlet.
The cable between the Business Communications Manager expansion unit and the Business
Communications Manager base unit is supplied with the expansion unit. Do not use any other
cables or connectors.

Internal wiring requirements
This section describes the requirements for a digital loop and an analog loop within the system.
Digital loop
The following parameters must be met for a digital loop:
• one, two, or three twisted-pair cable(s) per telephone
• dc loop resistance of less than 64 ?
• cable length (0.5 mm or 24 AWG) less than 300 m (975 ft.)
• use of a station auxiliary power supply (SAPS) for loops 300 m (975 ft.) to 1200 m (3900 ft.).
In North America, the SAPS must be a CSA or UL approved Class 2 power source.
In Europe, the SAPS must be a Class II power source and CE marked.
• no bridge taps
Danger: Risk of electric shock.
The safety of this product requires connection to an outlet with a third wire ground. Use
only with a three wire power cord and outlet.
Caution: Check ground connections.
Ensure that the electrical ground connections of the power utility, telephone lines and
internal metal water pipe system, if present, are connected together. If these ground
connections are not connected together, contact the appropriate electrical inspection
authority. Do not try to make the connections yourself.
104 Chapter 2 Auxiliary Requirements and Installation Process Overview
N0008586 02
Analog loop
The following parameters must be met for an analog loop.
• maximum dc loop resistance of 208 ?
• maximum cable length (0.5 mm or 24 AWG) of 1220 m (4000 ft.)
