Checking commercial power and connecting AC power Before powering up the media gateways,
check the AC power using a KS-20599 digital voltmeter (DVM) (or equivalent).
1 Set the DVM to the 250 volt range.
2 Carefully measure the voltage between the hot and neutral side of the receptacle. The neutral wire
is white, the hot wire is black.

4 Measure the voltage between the neutral and ground side of the receptacle. The ground wire is
green.
5 Verify the meter reads 0 VAC. If not, have a qualified electrician correct the problem.
