I was experiencing ERR5417 on 24 0 0 11 and 15. This was an analog card but there was nothng on unit 11. I moved all the units that were on 24 0 0 and moved them to loop 12. That cleared the ERR5417 but now I am getting ERR020 on 24 0 0. I tried to out the card but it tells me that it is unequiped. ANy suggestions would be helpful.
