This is a good point to remember: shutting down modern motherboards
*does not* remove all voltage from all lines of the bus connector...
and that can keep cards from resetting.

As I discovered this week, even a "hard" power switch on the back isn't
always good enough -- we installed a server with hot-swappable dual
power supplies, each with its own rocker switch.

Turning off both rocker switches *still* did not cause the wake-on-LAN
lights on the Ethernet jack to go out.  I had to unplug both power
cords to accomplish that.

I suspect Underwriters' Laboratories Would Not Be Pleased.  

Cheers,
