Thanks for the reply. I checked the list of things on your list, but everything seems to be right. This card is on a network that has been running for about 3 years and I am having trouble finding a reason for the recent problem. Nothing has changed as far as I can tell. I also checked the forward loop and reverse loop status to see if there was a fiber break, but the whole network shows up good. So, I replaced the card thinking that it had to be the problem and it faulted out again today. I am running out of ideas of what it could be that would cause it to fault out only once a day or every other day like this after it ran for so long. Thanks again for the reply.
