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.

AC Version
DC Version


The Alarm1, Alarm2, System and Fault LEDs are mirrored on the LOMlite2 card visible from the rear of the system.

Front Panel LED Functions
LED Icon/Legend Color Function
Fault1
Amber Driven by the LOMlite2 module under identified system fault conditions
Power
Green Illuminated continuously while power is supplied to the system.
System1
SYSTEM
 Green Off (or reset) during power up procedures and illuminated when UNIX is running and the Alarms driver is installed. This LED is reset by a hardware Watchdog timeout, or whenever the user-defined Alarm3 is asserted.
Alarm11
ALARM1
 Amber Illuminated whenever the user-defined Alarm1 is asserted
Alarm21
ALARM2
 Amber Illuminated whenever the user-defined Alarm2 is asserted
Input A OK
DC-A
 Green

Illuminated when the input voltage from feeder A is above 37V

Off when Input A is below 35V

Not used by the Netra 20 AC Version
Input B OK
DC-B
 Green

Illuminated when the input voltage from feeder B is above 37V

Off when Input B is below 35V

Not used by the Netra 20 AC Version
Disk0 OK to Remove2
Blue Illuminated, in response to a user request, when Disk0 can be removed safely without affecting the system operation
Disk0 Fault2
Amber Illuminated when the system has identified a fault in Disk0
Disk0 Active2
Green Illuminated when Disk0 is active
Disk1 OK to Remove2
Blue Illuminated, in response to a user request, when disk1 can be removed safely without affecting the system operation
Disk1 Fault2
Amber Illuminated when the system has identified a fault in Disk1
Disk1 Active2
Green Illuminated when Disk1 is active
1 These LEDs are duplicated on the LOMlite2 card face plate.
2 Lower the front fascia to view these LEDs.

LOMlite2 LEDs

The LOMlite2 status LEDs, which mirror the alarm status and power LEDs on the front panel, are located on the rear of the system, between the LOMlite2 DB-15 alarms relay port and RJ45 serial port.

LOMlite2 Status LED Functions
LED Icon/Legend Color Function
Alarm1
1
 Amber Illuminated whenever the user-defined Alarm1 is asserted
Alarm2
2
 Amber Illuminated whenever the user-defined Alarm2 is asserted
Fault
Amber Driven by the LOMlite 2 card and illuminated when a system fault condition exists
System
SYS
 Green

Illuminated when Solaris is running and the LOMlite2 driver is installed

Off while the system is powering up Reset by watchdog timeout, assertion of user-defined Alarm 3
