Step 1 Verify that there is a suitable AC power outlet available.

Caution Do not plug this unit into an AC outlet that does not have a UL-certified receptacle that is properly tied into building ground.

Step 2 Place the four rubber feet (from the accessory kit) in the four indentations on the underside of the chassis.This helps provide proper airflow through and around the chassis.

Step 3 Place the Cisco VG224 voice gateway on a smooth, flat surface.

Caution Do not place anything on top of the chassis that weighs more than 10 lb (4.5 kg). Excessive weight on top can damage the chassis.

Installing the Ground Connection

Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024

Warning AC connected units must have a permanent ground connection in addition to the power cable ground wire. NEBS-compliant grounding satisfies this requirement. Statement 284

Warning Use copper conductors only. Statement 1025

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.

•For NEC-compliant grounding, use size AWG 14 (2 mm2) or larger wire and an appropriate user-supplied ring terminal.
