The iNS has several LED indicators: Status, Serial ports, and Ethernet.
The LEDs use red, yellow, and green blinking combinations to indicate the status of each of
the iNS’s major components.
Status LED
The status LED indicates the overall status of the iNS. See Table 4-1.

system log for more details.
