4.4 UPS Power Supply
The power feed is 12 VDC. The GPON 452/454 utilizes an uninterruptible power supply
(UPS). A UPS is a battery backup system designed to continue providing power when the
primary power source is lost. When the UPS senses a loss of power from the primary source,
the backup battery is activated to provide power for a short period of time.
Power is supplied to the GPON 452/454 by a UPS local power source (P/N: 1187731G1) with
battery backup that utilizes the AC power at the customer premises. The unit powers the
GPON 452/454 and functions as a battery backup supplying continuous 12 VDC. It contains
one sealed, lead-acid battery for power backup.
If the battery is disconnected, the GPON 452/454 is not protected from power outages, and
will send a “Battery Missing” alarm to the OLT.
Install the UPS per the specifications recommended by the manufacturer.
NOTE
g
The UPS does not include a power/alarm cable (P/N: 1187732G1) but one be purchased
separately from ADTRAN.
