3750 Connectivity issue

I have a WS-C2960G-24TC-L

with a 1000base LX SFP

connected via single mode to an Incomming gigabit circuit from SSE/Telco (Scottish and Southern Electric)

this configuration works ok.

When i move the connection to a WS-C3750X-12S-S   (with the same sfp) i get no connectivity, no physical or anything,

has anyone seen this before when i do a show interface it does nothing, not connected etc.

Any top tips and handy hots would be appreciated
