I happened to notice this evening that the left LED on the ethernet port was lit, when no cable, or connection was present.

Expected outcome:
----------
No cable, or connection, no lights.

Other scenarios:

Cable plugged in, gig-e switch connection:
-------------
expected lights:
    left: green
    right: activity

observed lights:
    left: green
    right: nothing

Cable plugged in, 10/100 switch connection:
-------------
expected lights:
    left: amber
    right: activity

observed lights:
    left: green
    right: green activity


I can try some more combinations but I figured I'd report what I have easily available
