Installing the Avaya S8700 Media Server with an Avaya G650 Media Gateway
December 2003
Fault Conditions
If the AC outlet tests that follow reveal any of the following conditions, they must be
corrected BEFORE you install the system.
•
Open ground
•
Hot and neutral reversed
•
Open hot
•
Open neutral
•
Hot and ground reversed
!
WARNING:
Hazardous voltages are present during this test. Follow all instructions carefully when working the
AC power line voltages.
Verifying ground using an ideal 61-035 Circuit Tester (or equivalent)
1
Plug the circuit tester into the outlet that you want to test.
If the circuit is properly grounded, the yellow and white lights on the tester illuminate.
2
Unplug the tester.
!
WARNING:
If the tester indicates any type of ground fault, your customer must contact a licensed electrician.
DO NOT install the system.
Verifying voltages using a Volt-Ohm Millimeter (VOM) (U.S. and countries using 110 to
125 VAC power)
!
WARNING:
Hazardous voltages are present during this test. Follow all instructions carefully when working
with AC power line voltages.
NOTE:
The following example is for North American voltages (110 to 125 VAC). Use the
appropriate voltages for local power.
1
Be sure that the VOM is set to read Volts AC.
2
Set the VOM to the lowest scale on which you can read 130 VAC.
3
Measure the AC voltages in the following order:
If the voltage readings do not measure the values given, the AC outlet is improperly wired. DO NOT
INSTALL THE SYSTEM. Advise the customer to have a licensed electrician correct the problem.
You are now ready to power the system.
a
Phase to neutral should be 110 to 125 VAC.
b
Neutral to ground should be less than 1 VAC.
c
Phase to ground should be 110 to 125 VAC.
