oh, now that you mention it, they're with the logos and
glitz - on the front - rather than where all the action is - 
the wires and antennas - at the back. I was trying to block out
the glitz. It hadn't occured to me that the lights 
on the front indicated anything useful.

hmm, I guess I'm a two light kinda guy.

Now that I look I see that the order of the lights is left-to-right 
inverted - the left light indicates the state of the port on the right 
etc. I think I'd seen this before and decided to figure out later why 
the lights didn't do anything sensible.

Thanks for the correct nomenclature.
