Warning

Installing the Cisco VG310 and Cisco VG320 Voice Gateways

Mounting Screws

If installed on enclosed racks, the racks must have adequate ventilation. An enclosed rack should never be

overcrowded and should have louvers and a fan.

Caution

If the Cisco VG310 or Cisco VG320 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 pass through the Cisco VG310 or Cisco

VG320 chassis.

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 chassis 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.

Tip

Machine screws for securing the chassis in a rack are not included in the package. You must arrange for

machine screws of the appropriate size required by your rack.

Note

Procedure

Step 1 Attach the long leg of the mounting brackets to the chassis.
