Installing the chassis in an equipment rack

To mount the VPN Router 2750 in an equipment rack, you need the following equipment:

•a standard 19-inch equipment rack

•four screws (supplied with the chassis)

•four cage nuts (supplied with the chassis) if the rack does not have threaded rail holes

•a #2 Phillips screwdriver

Rack-mount recommendations

When you mount the chassis in the equipment rack, observe the following standard recommendations:

•Nortel recommends a maximum ambient temperature of 40oC (104oF). Ensure that the internal temperature of the rack does not exceed (104oF).

•Do not block the power supply vents or otherwise restrict air flow when installing the chassis in the rack.

•Stabilize your rack so that it does not tip over under the weight of the gateway and other devices.

•Ensure that the electrical branch circuits can handle the VPN Router 2750 and other units in the rack before you install and turn on the gateway.

•Maintain a reliable earth-ground path in the rack system. You must connect the gateway to an earth ground.

Attaching the shelf in the equipment rack

The VPN Router 2750 ships with a rack-mount shelf to support the chassis in the equipment rack.

To attach the shelf to the inside of the equipment rack:

1If the holes in the rack’s vertical supports are not threaded, attach a cage nut in four locations at the front of the rack (Figure 3 on page 31).
