The usual lights on a NIC are:

1. LINK

  This lights to indicate that a physical connection to another network
device exists -- i.e., the cable is connected and is probably of the right
type to allow data to flow.

2. ACTIVITY

  This light will blink when data is actually flowing.

3. SPEED (optional)

  10/100 NICs often include a light which indicates which speed the link is
actually operating at.

  Note that you should not expect to see ACTIVITY or SPEED lights without
LINK, and you will not see LINK until the network cable is plugged in.
