Installing the chassis in an equipment rack
To mount the Contivity 1700 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
o
C (104
o
F). Make
sure that the internal temperature of the rack does not exceed 40
o
C (104
o
F).
• 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 1700
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.
Attaching the shelf in the equipment rack
The Contivity 1700 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:
1 If the holes in the rack’s vertical supports are not threaded, attach a cage nut in
four locations at the front of the rack
