You have non-Cisco approved SFP's. What's more, it looks like your
SFP's were made by little elves that copied one real SFP. They copied
the same CRC value on both of the SFP's. When your switch detects the
duplicate value on the SFP's, it knows that their non-approved.
You can buy real ones or use Cisco's hidden command to circumvent this.
You'll have to search the archives or the web for the command.
Cheers.

I have a CISCO Cat2960G; it was working fine, due to power shutdown, one
of the CISCO fiber SFP ports went down, since then I was not able to
bring it up, now when I replace this SFP with the new one I got the
following error message
