This chapter describes the function of the LEDs on the Netra 20 system.
The chapter contains the following sections:
The Netra 20 server has three sets of LEDs that show the status of the system.
System LEDs
The system LEDs are located behind the front fascia, immediately to the right of the ON/STBY switch as you face the unit, as shown in FIGURE 6-1.
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 (see LOMlite 2 LEDs).
