From what I've gathered on the forums I may have incompatible GBICs between my 3750 and a new 2960. The 3750 has older 1000Base-SX modules and the GBIC installed in the 2960 is a GLC-SX-MM. Is my assumption correct that I would need GLC-SX-SM?
Thanks. We think this is the issue since we've discovered that our installers ran single mode fiber. I'm assuming that would prohibit us from using the MM module, correct?
