Planning Your Installation
For safety, periodically check the resistance value of the antistatic strap, which should be between 1 МΩ
Caution
and 10 МΩ.
Temperature Control and Ventilation
The installation location (room, closet, or cabinet) for Cisco VG310 and Cisco VG320 should always be well
ventilated and provide adequate air circulation to ensure proper cooling. The room temperature should be
between 32 °F and 104 °F (0 °C to 40 °C).
Note
The Cisco VG310 and Cisco VG320 analog voice gateway chassis is designed for back-to-front airflow.
Enclosed Racks
Enclosed racks must have adequate ventilation. An enclosed rack should never be overcrowded and should
Note
have louvers and a fan.
If the Cisco VG310 or Cisco VG320 analog voice gateway is installed in an enclosed rack with a ventilation
fan at the top, make sure that heated air drawn upward from other equipment does not prevent adequate
cooling.
If the chassis is installed using slide rails, check for blocked ventilation ports when it is in position in the rack
or cabinet. Make sure that the ventilation ports of the unit are not blocked.
Baffles can help isolate exhaust air from intake air. Baffles also help draw cooling air through the cabinet.
Note
The best location for baffles depends on the airflow patterns in the rack. You can test the airflow by
experimenting with different equipment arrangements.
Wall-Mounted
If Cisco VG310 or Cisco VG320 is installed on a wall, there should be plenty of space on both sides to ensure
that there is adequate airflow through the chassis.
Bench-Mounted
If the unit is placed on a bench top, do not stack other equipment or paper on the chassis. Provide plenty of
space for air circulation (front to back). Inadequate ventilation can result in overheating and damage.
