Thank you for your replies, As far as having enough cards to convert fully to a 4 fiber BLSR, we do not have enough, and there are no other slots available in the chassis. I was thinking of removing the protect cards, placing the 192s in there, and then assigning those to do the protect. Then once we've done that across the ring we would switch all the working traffic to the 192s and remove the remaining 48 cards. Then I was hoping there would be a quick way (even if small downtime is required this wouldn't be terrible) to change to a 2 fiber BLSR. Again thank you very much for all your help ... View more

Sorry, but yes it is a 15454. And your suggestion is what I was originally going to do but there are only 4 slots that can take the OC-48 cards and the OC-192 cards in my particular chassis. And since we have a 4 fiber BLSR all 4 of thos slots are already taken up. Can we take out the protect ring cards and put in the 192 cards, move all the traffic over to them and then once the ring is complete force it into being a 2 fiber BLSR? Will the 15454 accecpt having a 4 fiber BLSR temporarily with 48 cards on the working and 192 cards as the protect? ... View more
