About Your Drive
Activity and Failure LEDs
G-RAID contains LEDs for drive activity (WHITE) and drive failure (RED) that are next to
each other on the front panel and describe the following operations:
• System initialization
• System ready
• Disk activity
• Disk drive failure
The following table explains the meaning of each combination of LEDs on the drive.
When both LEDs are illuminated, the color turns lighter RED.
The activity light will glow when power is applied. It will flash brighter as data is
transferred to or from the hard drive.
In the event of a disk drive failure, the RED drive failure LED located on the front panel
will illuminate. In RAID 1 mode - If the red light flashes once per second, it indicates that
the top drive has failed; if the red light flashes four times per second, it indicates that the
bottom drive has failed. If a drive failure occurs in RAID 0 mode then the LED in the front
panel turns constant RED.
• If congured in fail-safe RAID 1 mode, all the data stored on the system will be intact.
• If congured in JBOD mode, only the data in the bad drive will be lost; the rest of
the data will be intact.
• If congured in RAID 0 mode, all data will be lost. Please contact Technical Support
for help if the RED LED is constantly lit indicating drive failure.
