Warning!! New to Avaya. Nortel guy. Go easy!! I am working on a 3 carrier rls 6.1 Legend. Card slot 5 has a 012 card that went south. I correctly powered down, removed the card of the backplane, reinserted and powered up. No change. Installed a new/refurbed card, no change. The ports don't even have battery on them. Carrier 3 has the last slot 17 open. It is programmed as a 408. Can I install the 012 there, do a board renumber, then renumber/reprogram the extensions, and get these 12 people up and running?
