Yup, when i tried getting the existing 1A05 card (which is 24 port analog) then put it on 1C01 it did alarm after a few miniutes. And when i put it back on the original slot which is 1A05, the alarm is still there.

Also, the new boards that alarmed, did you try them in a slot that already has a TN2793 in it? ---- Yes I did. Still the same.

If you can observe, almost all cabinets A and B, already filled up with a 24 port analog, and the remaining cabinet C only hav 16 port. I have asked our pre-sales to reconfigure the clients PBX and the results on the avaya configurator requires a call classfier on cabinet C, in which the current setup doesn't have.

Ok i'll be checking the bents pins. However if there is a bent pin, the 16 port analog wont be latched and wont provide dialtone. I already encountered problems with those pins before, any bent pins on the backplane wont allow any equipment to be inserted. If you push it hard, the pins will be broken.
