SFP-10G-AOC10M does not detected by WS-C2960X-48FPD-L

Question

Hello.
I've got two SFP-10G-AOC10M optical transceiver modules, and want to use them as uplinks for Catalyst 2960-x switch stack to 4500-X.
When I insert SFP modules to Cat2960-X I get next messages in log:
%PHY-4-SFP_NOT_SUPPORTED: The SFP in Gi4/0/50 is not supported
%PM-4-ERR_DISABLE: gbic-invalid error detected on Gi4/0/50, putting Gi4/0/50 in err-disable state
%PHY-4-SFP_NOT_SUPPORTED: The SFP in Gi5/0/50 is not supported
%PM-4-ERR_DISABLE: gbic-invalid error detected on Gi5/0/50, putting Gi5/0/50 in err-disable state
Looks like switches detected this modules as 1G not 10G.
According to Cisco 10-Gigabit Ethernet Transceiver Modules Compatibility Matrix these modules should be supported by Cat 2960-X with 15.0(2)EX IOS release. I had 15.0(2)EX5 release and even upgraded to 15.0(2a)EX5.

I've inserted two other modules in this ports and they are detecting correctly:

Any ideas?

Hello.
That is the problem. Switch has 48 Gigabit ports and they appear as Gi4/0/1-Gi4/0/48. And two uplink ports for SFP or SFP+ modules. 10Gig uplinks module should be detected as Te4/0/1 and Te4/0/2. Gigabit will be detected as Gi4/0/49 and Gi4/0/50.
Once I insert SFP-10G-AOC10M to the switch uplink port I get messages in logs:
%PHY-4-SFP_NOT_SUPPORTED: The SFP in Gi4/0/50 is not supported
%PM-4-ERR_DISABLE: gbic-invalid error detected on Gi4/0/50, putting Gi4/0/50 in err-disable state
So instead to be detected as Te4/0/2 it is detected as Gi4/0/50.
I've tried to insert into uplink ports two other modules: GLC-T (1gig) and SFP-H10GB-CU3M. And they are detected correctly(see two last outputs in first post).
