Installing the Chassis Ground Connection

Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

•This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

•When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.

•If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack. Statement 1006

Warning To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles on modules (such as power supplies, fans, or cards); these types of handles are not designed to support the weight of the unit. Statement 1032

Using screws that you provide, attach the chassis to the rack. (See Figure 3-11.)

Note:The brackets can also be installed with the rear panel forward.

After the router has been installed, you must connect the chassis to a reliable earth ground. For the chassis ground connection procedures, see the “Installing the Chassis Ground Connection” section on page 3-8.

Installing the Chassis Ground Connection

All Cisco 3700 series router chassis require a reliable earth ground connection. You must connect the chassis to a reliable earth ground; the ground wire must be installed in accordance with local electrical safety standards.

•For NEBS-compliant grounding, use size AWG 6 (13 mm2) wire and the ground lug provided in the accessory kit.
