When the Global Enclosure LED on VessRAID’s front panel shows Amber or
Red, check the LEDs on the back of VessRAID. These LEDs give the status of
individual components. See page 269, Figure 5.
Disk Drive LEDs
There are two LEDs on each Drive Carrier. They report the presence of a disk
drive, activity of the drive, and the drive’s current condition.
Figure 3. VessRAID disk drive carrier LEDs
If there is a disk drive in the carrier, the Power/Activity LED displays Green. If not,
the Power/Activity LED remains dark.
