while moving my computer around in inadvertantly plugged my visioneer 4400 usb scanner power supply into my 3com 3c510 router and vice versa. the scanner, which you'd think would be more fragile, is fine. but i can't get the router to work now. the green connection light comes on for the connection to the computer, but the steady blinking "system is okay" light is gone and i can't access the net.

i've tried letting it cool down, resetting it, the modem, tried using a serial cable to hyperterminal in (no response). anything else i can try, or should i just trash it?

Yup, you are almost certainly screwed. But did you look at the output specs on the two power supplies to find out what you plugged into what?

Your scanner has a motor, lamps, etc. It probably draws a LOT more power than your router. When you plugged the scanner power supply into the router, you gave it a lot more juice than it was intended for. You probably shorted something out. Generally, plugging in a smaller power supply isn't a problem, but a larger one definitely can be.

Are you sure there isn't something else wrong? Mis-plugged a cable, etc? That can easily happen when youmove things around.

Check the router's manual to see if it has any circuit-breaker or a fuse. I made a similar mistake (actually worse as I plugged a 110 volt pc speakers to a 240 volt outlet...I was drunk) but just replaced the fuse ($0.50) inside the Altec Lansing speakers and saved myself $200.
