Issue:
Meaning of the Green LED on the X80 Ethernet Backplane


Product Line:
M580, M340


Resolution:
The green status LED marked OK on Ethernet racks indicates if the rack is working properly. When this LED is ON, these conditions (which are internal to the rack) have been fulfilled:

1. The power rail voltages are in the rated range.

2. The X bus diagnostic is working properly.

3. The Ethernet switch diagnostic is working properly.

When the LED is OFF, the backplane is not operation.
