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.
