properly and the drives are
working (read/write)
Blinking blue/red Blinking blue/red RAID synchronizing; will
cease once operation has
concluded
Blinking red Solid red for non-functional disks RAID is degraded; data is
intact but the array is no
longer protected should
another disk fail
Solid red Activity LED for working
disks
Temperature alert (critical
level) – the product will
shut off
- Activity LED for working
disks
Operating system update in
