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.
