Green lights on a switch

Here's an easy one for someone, but just not for me.

I plugged all our computers into a switch. All but one has two green lights that come on when they plug into the switch. One cable only has one of the green lights come on. This particular cable goes into a hub and then two more computers. They appear to be functioning normally, but it puzzles me as to why only one green light is lit. Does this indicate some type of problem and what does it mean?

Without knowing what EXACTLY you have in terms of hardware (models would be helpful), I can't say for certain, BUT, I would suspect that the switch is a 10/100 switch, one LED is for Link Lights (indicating a connection to a device at the other end), the other is indicative of a 100Mbit connection speed.  If there is no light on that one, then the speed is 10Mbit.  So the hub is probably a 10Mbit hub, not 100Mbit.  (the hub is thus MUCH slower than the switch).

Thank you so much. That makes perfect sense now. I was totally unaware that this is what the second light was for. It is a Netgear Fast ethernet switch
