Troubleshooting

Several status indicators provide general system status, alert you to system problems, and help you to determine the location of system faults:

●At the top of the status and control panel, three general status LEDs provide a snapshot of the system status.

●Below the power button and security key switch, a graphical display provides additional LED icons to indicate specific fault conditions and locations.

The general status LEDs work in conjunction with the specific fault LED icons. For example, a fault in the disk subsystem illuminates both the system fault LED at the top of the panel and the disk fault icon in the graphical display below it. Fault LEDs within the enclosure help pinpoint the location of the faulty device. Since all front panel status LEDs are powered by the system's

5-volt standby power source, fault LEDs remain lit for any fault condition that results in a system shutdown.

During system startup, the front panel LEDs are individually toggled on and off to verify that each one is working correctly. After that, the front panel LEDs operate as described in the following table.

Name	Icon	LED function
Power/OK		This green LED lights when the system is turned on.
System fault		This amber LED lights to indicate a serious system fault. When
		this LED is lit, one or more icons in the display panel may also
		light to indicate the specific nature and location of the fault.
OK-to-		This amber LED lights to indicate that an internal
remove		hot-pluggable component is ready for removal.
Disk fault		This amber LED lights to indicate a serious disk subsystem
		fault that is likely to bring down the system. When this LED is
		lit, one or more disk LEDs may also be lit at the front of the
		disk cage, indicating the source of the fault. See Disk drive
		status indicators on page 182.
Power fault		This amber LED lights to indicate a serious power subsystem
		fault that is likely to bring down the system. When this LED is
		lit, one or more power supply LEDs may also be lit on the
		system rear panel. See Power supply status indicators on
		page 181.
