Every time I try to upgrade to this newer clock controller. Option81c system will freeze up after kicking out numerous fnet errors. I used switch settings described on card, last two switches were not mentioned but were turned on from factory. So I left them that way,and I used slot 13 in Group 1. I never get past the install of one card. Tried second card in same location but results were same. Any Suggestions?
