1.2.3.2 LED lamp

For PRIMEPOWER 1

There are ALARM LEDs, CHECK LED, and FAULT DISK LEDs.

Each ALARM LED will either blink or light constantly when there is a failure in the corresponding portion of the system hardware. Refer to "Table 1. 3 ALARM LEDs" below.

[Table 1. 3 ALARM LEDs]

ALARM LED	Condition: blinking or lit
PWR LED	Lit constantly when power supply failure occurs.
THRM LED	Lit constantly when abnormal temperatures occur.
FAN LED	Lit constantly when fan failures occur.
SOFT LED (PRIMEPOWER1 only)	Blinking or lit constantly when other failures occur. Refer to "Machine Administration Guide."

If any ALARM LEDs blink or light up constantly, the CHECK LED will also blink or light up in the same way.

Each FAULT DISK LED will stay lit while hot-swapping internal disks.

If a fatal error occurs on the system, these LEDs will stay lit and Solaris OS will not boot up, even if you turn on the power.

Degraded operation occurs when there is a failure in some portion of the system hardware, rendering the failed hardware unusable. These LEDs will blink while the system is under degraded operation. The fjprtdiag (1M) command displays information on failed hardware.

For PRIMEPOWER 250/450

The CHECK LED will either blink or light constantly when there is a failure in some portion of the system hardware. If a fatal error occurs on the system, the CHECK LED will light constantly and Solaris OS will not boot up, even if you turn on power.

Degraded operation occurs when there is a failure in some portion of the system hardware, rendering the failed hardware unusable. The CHECK LED will blink while the system is under degraded operation.

The fjprtdiag (1M) command displays information on failed hardware.

In PRIMEPOWER 250/450, to specify target processor at maintenance etc., the CHECK lamp of the Main Cabinet can be lit or blinked. Refer to the nodeled(1M) command.
