Annoying, but I'm not physically near the system that > much. If I recall correctly, on the GT20 the backplane didn't have the > capability to light the LEDs (although then I don't understand wtf > there are LEDs there... perhaps Windows has some way of lighting them). > > Cheers, > Dan I have a similar problem with a supermicro system with sc743tq-865-sq chassis + x7dwa-n motherboard, the chassis has a 8 drive hot swap backplane but the motherboard only has 6 ports, the 6 drives that are connected to the m/b have working led's but the 2 remaining drives only flash when the drives spin up, the activity and status lights remain off the rest of the time. I've never figured out how the led's are driven, the backplane does have two gpio ports which could be connected to gpio on the motherboard, but I have never used them and it seems to work ok as it is.
