Correct!

The fiber is 62.5/125 and it is what they have in place . The project wasn't to reinstall there fiber but to consolidate one of there IDF locations from a 2 post rack to a wall cabinet

Which included removing there exiting fiber connections into there newly installed switches that they had recently upgraded

They ended up using the exiting GBIX cards from the old switches .They just spent hours trying to figure out why it wasn't working

So it appears that there is a compatibility issue


Thanks for response!
