Each RAID canister has a set of LEDs which are defined in the following figure.
The table describes the LEDs functions and colors. The LEDs labeled '1' track the
data rate of the link. If both are off, the link is inactive, and if both are on, the data
rate is 8 Gb per second. If only one LED is on, the LED on the left indicates a 2
Gb/s data rate, and the one on the right indicates a 4 Gb/s data rate. The canister
also displays the ID of the Primary Storage Shelf, which is set to '99'.
