Installing a UPS

To install a UPS:
1. Connect the UPS to an electrical outlet that can handle the power requirements of the G650
Media Gateway:
a. 100 VAC, 7.2 A
b. 120 VAC, 6.4 A
c. 200 VAC, 3.3 A
d. 220 to 240 VAC, 2.8 A
For more information, see
page 33.
2. Ensure that the G650 Media Gateway is connected to an electrical outlet on the UPS that is
"nonswitched" or "always on."
3. Connect and administer the Avaya UPS. Note that customers must connect and administer
any 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 issues a major alarm for the following
conditions:
Loss of AC. The advertised holdover time is available.
●
UPS on bypass. The UPS failed and must be serviced.
●
Low battery warning is issued at approximately 5 minutes before shutdown.
●
Note:
If the UPS is wired as recommended, the Avaya UPS issues a shutdown warning
Note:
5 minutes prior to the end of life of the battery. A UPS handles any subsequent
power outage based on the total battery capacity of the UPS.
