LEDs on the 5104-22C, 9006-22C, or 9006-22P system

Use this information as a guide to the LEDs on the system.

The LEDs indicate various system status. If the part does not have a problem indicator LED, you can use a troubleshooting program such as impitool to identify the issue.

The front LEDs are shown in Figure 1.
  • The green LED (6) indicates the power status.
  • The identify LED (2) can indicate the following states:
    • Flashing blue indicates that a remote UID command was run.
    • Solid red indicates that the system is overheated.
    • Flashing red at 1 Hz indicates that a fan failed.
    • Flashing red at 0.25 Hz indicates that a power supply failed.
  • The amber LED (5) flashes when there is SATA drive activity, for SATA drives directly attached to the system backplane.
  • The network activity LEDs (3) and (4) flash when there is network activity on the feature EKA8 four port network card.
  • The red LED (8) indicates a power supply failed.

Drive LEDs can indicate the following states:
  • Blue activity LED can indicate the following states:
    • When there is no activity, the LED is off for SATA drives; on for SAS drives.
    • Flashing blue indicates activity
  • Red status LED can indicate the following states. The status LED does not work when SATA drives are directly attached to the system backplane.
    • Steady red indicates that the drive failed
    • Flashing red at 4 Hz identifies the drive
    • Flashing red at 1 Hz indicates that the drive is rebuilding
Power supply LEDs can indicate the following states:
  • Steady green indicates that power is on
  • Flashing green indicates that AC is applied, but the system is powered off.
  • Steady amber indicates that AC is not applied, or a power fault occurred
  • Flashing amber indicates that the power supply is overheating
