[c-nsp] SFP port in 2960 series

[Ataklti Teklehaymanot]

I want to use the SFP port
I have cisco switch 2960 with Version 12.2(50)SE
and I have also GLC-LH-SM SFP transceiver
When I plug the SFP transceiver without anything it gives me an error
%GBIC_SECURITY_CRYPT-4-ID_MISMATCH: Identification check failed for
GBIC in port Gi0/1
%PHY-4-UNSUPPORTED_TRANSCEIVER: Unsupported transceiver found in Gi0/1

please help me what I have to do. Thank you for your time
