2400IMX with 2.5 stacks. All appears to be OK except one 16LCB card. Card was green, but could not get dialtone from it, and the programmed phones were in MBST.
Flipped up Make Busy switch and pulled card. Reseated it and flipped switch down. Card would not go green. Tried swapping with a known good card, same result.
