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.

Figure 2: Attaching the Brackets to a Chassis (For Telco 19-Inch Rack)
Step 2
Position the chassis on the rack to align the holes on the short leg of the bracket with the appropriate holes
on the 19-inch rack.
Step 3
Using the machine screws (not supplied), attach the bracket to the rack to secure the chassis in the rack. (See
the following figure.)
