Temperature Control and Ventilation

Note

The Cisco VG400 Voice Gateway chassis is designed for back and sides-to-front airflow.

Temperature Control and Ventilation

The installation location (room, closet, or cabinet) for the Cisco VG400 Voice Gateway should always be

well ventilated and provide adequate air circulation to ensure proper cooling. The room temperature should

be maintained between 32 to 104°F (0 to 50°C).

Note

The Cisco VG400 Voice Gateway chassis is designed for back and sides-to-front airflow.

The following information can help you plan your equipment rack configuration:

• Allow clearance around the rack for maintenance.

• Enclosed racks must have adequate ventilation. Ensure that the rack is not congested, because the hardware

• When mounting a chassis in an open rack, ensure that the rack frame does not block the intake or exhaust

If the Cisco VG400 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.

Note

Enclosed racks must have adequate ventilation. An enclosed rack should never be overcrowded and should

have louvers and a fan

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 Cisco VG400 Voice Gateway are not blocked.

Baffles can help isolate exhaust air from intake air. Baffles also help draw cooling air through the cabinet.

The best location for the baffles depends on the airflow patterns in the rack. You can test the airflow by

experimenting with different equipment arrangements.

Allow space at the rear of the chassis for cable connections. Also consider the need to access the chassis for

future upgrades, maintenance, and troubleshooting.

generated by equipment at the bottom of the rack can be drawn upward into the intake ports of the

equipment above it.
