SheevaPlug LED states?

[Jeffsbach]

I just graduated from a NSLU2 to a new SheevaPlug from Globalscale. It came with no manual, CDROM, or documentation. Meteohub is up and running and the sensors should work once I replace the batteries. I see in the Meteohub 4.7 manual, the blue LED is used to signal the IP. Is there a document to explain what other LED states are possible and what they indicate? If not, then what is the "normal operating state" of the LEDs?

Now I know what the blue light is for. I would also would like to know what the other light is for. Power on?

BTW: This "other light" is currently Red. No known problems that I can see.
