Netra 20 LEDs
Front Panel LEDs
The system LEDs are located behind the front fascia, immediately
to the right of the ON/STBY switch as you face the unit. Light pipes transmit
the Power, System, Alarm1, Alarm2 and Fault LEDs through the fascia and are
visible from the front of the system. To view the remaining LEDs, you must lower
the front fascia.
The Alarm1, Alarm2, System and Fault LEDs are mirrored on the LOMlite2 card
visible from the rear of the system.
