anyone have issues with the ethernet port not working/lighting up?

I just received 10 Erupter Blades with a Backpane and I can't seem to get the Ethernet ports to connect.  The PSU seems to be in working order and the fans connected to two of the blades are running fine when plugged in but I'm not getting any response from the Ethernet ports from the blades, just the uplink is working. I also tried putting one of the blades directly to the router instead of the switch and still no response response?

These blades have been used before so do I have to reset them, and/or how do I reset them?




UPDATE:
I realize the backpane shouldn't be on a metal surface so I have just raised it but the problem persists.
