3560 is running c3560-advipservicesk9-mz.122-40.SE. The SFP (GLC-TX) has been tested in another 3560 and is recognized. Both the gi0/1 and gi 0/2 ports show the type as unknown.
Port Name Status Vlan Duplex Speed Type
Gi0/1 notconnect 1 auto auto unknown
Gi0/2 notconnect 1 auto auto unknown
Any ideas?

is the fiber gbc connected to anyting on the other end? or are you simply just plugging in a gbic?
if it has been tested on another switch that is the exact same model eith the exact same config - you might have just gotten super unlucky and gotten two bad ports on your switch...

Per the compatibility matrix here, that is a supported combination (assuming it's a Cisco GLC-T transceiver). That particular model is not one with the dual-purpose uplink ports, otherwise you might need to add the "media-type" command (reference).
Have you tried patching a Cat 5 cable in on your copper transceiver and extending it to another switch? Do you get link? (I'd also try while hard coding the speed - shouldn't be necessary but can sometimes help.)
Does your log show any event when you insert a transceiver into its slot?
