Rack-mount recommendations

When you mount the chassis in the rack, observe the following 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.
Warning: The Contivity 5000 weighs approximately 50 pounds (23 kg).
This weight is not evenly distributed; the right side of the gateway
weighs more than the left. Two people must lift the system into the
equipment rack.
• Make sure that the electrical branch circuits can handle the Contivity 5000
and other units in the rack before you install and turn on the system.
• 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 5000 ships with a rack-mount shelf to support the chassis in the
equipment rack. To attach the shelf to the equipment rack:

If the holes in the rack's vertical supports are not threaded, attach a cage nut in
