Installing the chassis in an equipment rack
To mount the VPN Router 2700 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 rack, observe the following standard
recommendations:
• Ensure that the internal temperature of the rack does not exceed the maximum
recommended ambient temperature of 40
o C (104 o F).
• Do not block the power supply vents or otherwise restrict air flow when you
install the chassis in a 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 2700 and
other units in the rack before you install and turn on the gateway.
• Maintain a reliable earth-ground path in the rack system. The gateway is
intended to connect to an earth ground.

The VPN Router 2700 ships with a rack-mount shelf to support the chassis in the
equipment rack.
