Installation
Installation and basic configuration
Install the Business Services Gateway 8-port (BSG8ew) or Business Services Gateway 12-port 
(BSG12ew/aw/tw) hardware and power supply and connect the cables for analog telephones and 
lines, the LAN, and the WAN.
Installation and basic configuration prerequisites
Determine the location for the BSG8ew/12ew/aw/tw, telephones, and other equipment based 
on space and electrical requirements.
Order the required trunks from the telephone service provider for BSG 12tw.
The installation area must be:
— a 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, dry, well ventilated, and free of traffic and excess dust
— within the temperature range of 5°C and 50°C (40°F and 120°F)
— from 20% to 80% non condensing relative humidity
— structurally strong and with enough space to support the BSG8ew/12ew/aw/tw units
— a minimum of 46 cm (18 in.) from the floor
— of sufficient height from the floor to prevent water damage
Power must be supplied from a non switched, unobstructed outlet within 1.5 m (5 ft) of the 
BSG8ew/12ew/aw/tw.
The supplied power must be a dedicated 110 V to 120 V AC nominal (or 220 V to 240 V AC 
nominal), 50 to 60 Hz, 15 A minimum service with a third-wire safety ground. The third-wire 
safety ground provides shock protection and prevents electromagnetic interference.
Caution: Risk of damage to equipment
To avoid damaging the equipment, you must connect the BSG8ew/12ew/aw/tw to an 
outlet with a third-wire ground. Use only the BSG power supply that comes with the 
equipment, and a three-wire power 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. If these ground connections are 
not connected, contact the appropriate electrical inspection authority. Do not try to make 
the connections yourself.
