I have a 5406zl as a top level switch with 10 GB SFP+ modules installed. I don't know what type of fiber cable is going from the MDF to the IDF, but the existing fiber cable is plugged into a 1 Gig SFP GBIC on a 2920 in an IDF. Since the 2920's have dual personality ports, I lose port to fiber and one per switch for uplink. And I need all ports for patch cables.
Will I be able to use the 10 GB SFP+ modules to from the 2920 to the 5406 in the MDF?
Thanks in advane.
