Our switch 4006 was working perfectly, I have rebooted the switch and the power is on. But when I connect PCs to the switch the green light doesn't come up on the ports and the rack status, is red.

there are four card on the switch type WS-X4148-RJ, and there is only status sine on the cards and they are all RED. all the ports on the cards doesn't show any lights.  and still the same?

 I ma sure it is some thing easy which I don't know how to fix it?
