Installing the chassis in an equipment rack

To mount the Contivity 1740 in an equipment rack, you need the following
equipment:
• Standard 19-inch equipment rack
• 4 screws (supplied with the chassis)
• 4 cage nuts (supplied with the chassis) if the rack does not have threaded rail
holes
• #2 Phillips screwdriver

Rack-mount recommendations

When you mount the chassis in the rack, observe the following standard
recommendations:
• The maximum recommended ambient temperature is 40
sure that the internal temperature of the rack does not exceed 40
• Do not block the power supply vents or otherwise restrict air flow when
installing the chassis in a rack.
• Stabilize your rack so that it does not tip over under the weight of the gateway
and other devices.
• Make sure that the electrical branch circuits can handle the Contivity 1740
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.

equipment rack.
