Sonnet Technologies Fusion R400S RAID (With Drives) - Manual (Page 8)

Status LED Indications
System Powered, No Data Reads or Writes
When the Fusion R400S RAID is powered on, and no data
is being written or read, the Power and Drive LEDs turn on
(Figure 5).
Drive Activity
When data is being read from or written to a drive, its
corresponding LED will flash during read and write activity
(Figure 6).
Drive Not Recognized
When one or more drive LEDs is off while the others
remain lit, the corresponding drive(s) is not recognized
(Figure 7). There are a few possible causes for a drive to not
be recognized, including: the corresponding drive module is
not plugged securely into the enclosure or the drive itself has
failed. There is a small chance that the enclosure is defective.
Clone, RAID 5, or RAID 10 Rebuild
After inserting a drive into the R400S RAID enclosure to
replace a failed drive from a RAID 5 or RAID 10 group (or
putting in a new drive to be cloned to), the Rebuild LED
lights up orange, and the Drive LEDs flash with activity
until the RAID has been rebuilt or the clone copy completed
(Figure 8). Once the rebuild is complete, the Rebuild LED
turns off.
