Interconnecting Catalyst 3750 and 2948G-L3

[tironevi]

I am trying to interconnect a Catalyst 3750 and a 2948G-L3 using fiber GBIC. The interfaces where the GBIC and fiber are attached show up as physically down. I have tried different ports and also changed both switches. No Luck. If I connect a 3524 to the 3750 using the same connection it works.

Are 2948G-L3 switches compatible with the 3750?

Thanks,

VT
