Ok, have booted the system up will all cards pulled except the processor and the first pdku. The keysets close by show no display but a few others show an extension number upon a button press. I did not check other keysets earlier so i reseated all the boards and powered up again with the same results. Some keysets no display, others with after a button press. Keysets with working displays have no dial tone and no trunck access. I am assuming the programming was lost. I did check the battery jumper and it was set to off, so i set it to on.
