Installing the Avaya G600 Media Gateway
October 2002
Before powering up the system, check the AC power in the equipment room using a KS-20599
digital voltmeter (DVM) (or equivalent).
To check AC power:
1 Measure the AC voltage between the hot and neutral sides of the receptacle.
2 Depending on the AC power source, verify that the meter reads 90 to 132 volts AC or
180 to 264 volts AC. If not, have a qualified electrician correct the problem.
3 Measure the voltage between the neutral and ground sides of the receptacle.
4 Verify that the meter reads 0 volts AC. If not, have a qualified electrician correct the
problem.
5 When finished, set the AC main circuit breakers to OFF.
Approved grounds

Approved Grounds.
Uninterruptible Power Supply
A recommended Uninterruptible Power Supply (UPS) may be used for power holdover. The
type of UPS depends on the holdover requirements. Total holdover capacity varies depending
on the UPS. The UPS must provide surge protection for the media gateway.
!
CAUTION:
The major alarm contacts are designed to be connected ONLY to a UPS that can indicate
that it is on backup power. For most non-Avaya UPSs, you should not use the major
external device leads.
1 Connect the UPS to an electrical outlet capable of handling the power requirements of
the media gateway:
a 100 volts AC, 4.5 amps
b 120 volts AC, 3.8 amps
c 200 volts AC, 2.3 amps
d 220 to 240 volts AC, 2.0 amps
2 Ensure that the media gateway is connected to an “nonswitched” or “always on”
electrical outlet on the UPS.
3 For an Avaya UPS, connect and administer the UPS.
NOTE:
If an Avaya UPS is wired as recommended, holdover time for each power outage is
1 minute before an automatic shutdown. A UPS may handle any subsequent power outage
based on its total battery capacity.
