Uninterruptible Power Supply - Avaya G650 Installing

Uninterruptible power supply

An uninterruptible power supply (UPS) can be used for power protection and holdover time on
loss of AC power which increases the G650 Media Gateway availability. Select an UPS that
meets the power capacity and holdover time that is required for your site. Go to

CAUTION:
The major alarm contacts are designed to be connected ONLY to an UPS that

can indicate that it is on backup power. For most non-Avaya UPSs, you should
not use the major external device leads.
To install an UPS:
1. Connect the UPS to an electrical outlet capable of handling the power requirements of the
G650 Media Gateway:
a. 100 VAC, 7.2 amps
b. 120 VAC, 6.4 amps
c. 200 VAC, 3.3 amps
d. 220 to 240 VAC, 2.8 amps

2. Be sure that the G650 Media Gateway is connected to a "nonswitched" or "always on"
electrical outlet on the UPS.
3. Connect and administer the Avaya UPS. (Customers are responsible for connecting and
administering a non-Avaya UPS.)
The holdover time for each power outage is part of the configuration of the UPS to support
the G650 Media Gateway string of carriers. The UPS will issue a major alarm for the
following conditions:
a. Loss of AC - then the advertised holdover time is available.
b. UPS on Bypass - indicates the UPS has failed and must be serviced.
c. Low battery warning is issued at approximately 5 minutes before shutdown.
Note:
If an Avaya UPS is wired as recommended, the UPS will issue a shutdown
Note:
warning 5 minutes prior to battery end of life. An UPS can handle any subsequent
power outage based on its total battery capacity.
