110 Installing and Upgrading the Avaya G700 Media Gateway and Avaya S8300 Media Server
Before you connect the G700 media gateway DC feed cable to the DC power source, check the
DC power source using a KS-20599 digital voltmeter (or equivalent).
To check DC power
1. Verify that the meter reads between -41Vdc and -56 Vdc across the -48Vdc and -48V
Return distribution leads from the DC source.
2. Verify that the meter reads 0V between the -48V Return lead of the DC power source and
the approved ground.
3. If either step 1 or step 2 fails the verification, DO NOT PROCEED with step 4 .
Request that a qualified electrician resolve the problem.
4. Connect the DC feed cable for each G700 to the G700 chassis.
5. Connect the DC feed cable for each G700 to the DC power source.
a. Connect the red insulated 10 AWG lead to the -48Vdc Return (positive) source.
b. Connect the black insulated 10 AWG lead to the -48Vdc (negative) source.
