Health Indicator Condition and any error exists (for example, a failed fan or hard drive) Corrective Action Invalid memory configurations can cause the system to halt at startup without any video output. See Getting Help. Hard-drive Indicator Condition The indicator lights green to indicate hard-drive activity. Corrective Action None required. Electrical Indicator Condition Corrective Action The indicator blinks amber if the system experiences an electrical error (for example, voltage out of range, or a failed power supply or voltage regulator). See the System Event Log or system messages for the specific issue. If it is due to a problem with the power supply, check the LED on the power supply. Re-seat the power supply by removing and reinstalling it. If the problem persists, see Getting Help.

Corrective Action Ensure that none of the following conditions exist: • A cooling fan is removed or has failed. • System cover, cooling shroud, EMI filler panel, memory- module blank, or back-filler bracket is removed. • Ambient temperature is too high. • External airflow is obstructed.
