HPE MSA 2050 SAN Storage - Diagnostic Procedures

Procedures

This section describes possible reasons and actions to take when an LED indicates a fault condition during initial system setup.

NOTE: Once event notification is configured and enabled using the SMU, you can view event logs to monitor the health of the system and its components using the GUI.

In addition to monitoring LEDs via line-of-sight observation of racked hardware components when performing diagnostic steps, you can also monitor the health of the system and its components using the management interfaces

Is the power supply voltage/fan fault/service required LED amber?

Diagnostics LED status: Rear panel power supply: voltage/fan fault/service required

Answer
Possible Reasons
Actions
No
System functioning properly.
No action required
Yes
The power supply unit or a fan is operating at an un acceptable voltage/RPM level, or has failed.
When isolating faults in the power supply, remember that the fans in both modules receive power through a common bus on the midplane, so if a power supply unit fails, the fans continue to operate normally.
  • Check that the power supply FRU is firmly locked into position.

  • Check that the power cable is connected to a power source.

  • Check that the power cable is connected to the power supply module.
