Diagnostic Indicators
The diagnostic indicators on the system front panel display error status during system startup.
- NOTE: No diagnostic indicators are lit when the system is switched off. To start the system, plug it into a working power source and press the power button.
The following section describes system conditions and possible corrective actions associated with these indicators:
- Health Indicator
- Condition
- Corrective Action
- If the system is on, and in good health, the indicator lights solid blue.
- None required.
- The indicator blinks amber if the system is on or in standby, and any error exists (for example, a failed fan or hard drive)
See the System Event Log or system messages for the specific issue.
- 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.
- Temperature Indicator
- Condition
- Corrective Action
- The indicator blinks amber if the system experiences a thermal error (for example, a temperature out of range or fan failure).
- 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.
- Memory Indicator
- Condition
- Corrective Action
- The indicator blinks amber if a memory error occurs.
- See the system event log or system messages for the location of the failed memory. Reinstall the memory device. If the problem persists, see Getting Help .
