Drive indicators​

Storage drives are located in the front of the storage block.

Each drive has two LED indicators:

  • Drive activity LED indicator:

    • On: drive activity is present

    • Off: no drive activity

  • Drive error/warning LED indicator:

    • Constant On: fault conditions are present

    • 4 Hz blink rate (four times a second): locating the drive

    • 1 Hz blink rate (once a second): rebuilding the drive
