I have 4 csu/dsu cards connected to T-1 lines in a cisco 3640 router. One of the cards appeared to have gone bad. So I swapped out the card then I had no light on the new card. I rebooted the router and then only two of the cards came back up. The new card plus one other one wouldnt come up. Neither of the cards that dont have lights show up in the running config, I also cant check the interface out at all its like they dont exist. Any idea would be appreciated

Also worth mentioning, both of the cards that arent turning on are on the same side of the router.

You probably need to turn on the card services for the router to recognize the cards with the controller t1 0 0 command and the timeslots commands.

it turn out to be a whole bank that housed two cards went bad. I switched banks reconfigured the cards (because when I changed banks they went from serial 1 to serial 3).
