We have a catalyst 4507R at the core of our network and a new IDF is being built. There will be a new MM fiber drop terminating at the core and I don't think there are any spare SFP slots available. There are 2 spare GBIC ports on our redundant supervisor card but from what I have read only the GBICS on the active card will work and those are already taken. There is 1 linecard slot left on the 4507, but I want to be prepared with options in case my boss tells me there is not enough money to purchase a line card. So, is it possible and recommended to connect a media converter that would convert a free copper gig-e port to fiber as a short term solution?
Thanks
