5. Status LEDs, Alarms, and Troubleshooting
For local supervision, three multi-color LEDs (Power, OSC, and Alarm) are part of the
front panel to display unit status information.
During booting and SW update, all three LEDs blink green, indicating that initialization
and isolation measurement are in process. When the boot process is finished, and the
repeater works properly, all three LEDs are green to indicate normal operation.
The table below shows possible alarm conditions indicated by the LEDs as well as
possible countermeasures.

During normal operation (after a correct
installation) this LED should always show a green
light as due the obligatory usage of a UPS, power-
related alarms cannot occur; simulation of these
alarms via SW, however, is possible.
