'LRI' 'Output 1'
LRI Option
The LRI lamp (red lamp) is located on the outside, on either the right or left side of the enclosure. The
lamp comes ON only when the power supply is running on backup power (STANDBY). During
normal AC line operation, the lamp remains OFF. Whenever a fault is detected, the lamp flashes to
indicate that service is required. The LRI can be used as a simple form of status monitoring by
allowing cable technicians to check the operational status of the power supply without having to
climb the pole and open the enclosure. Connect the LRI lamp to the jack on the front of the power
supply labeled LRI.
ACI Option
The AC indicator (green lamp) is located on the outside, on either the right or left of the enclosure.
When the lamp is ON, it indicates AC power is available at the power supply output. This allows a
cable technician to drive by and determine the status of the power supply without having to climb the
pole. Connect one connector of the ACI lamp to the OUTPUT 1 jack on the front of the power supply,
and the other to the SPI.
