Hello,
Sorry to say but JD092B is not supported for ProCurve 6120XG +.
JD092B is mainly used for comware based switches. These comware based transecivers has 'JD' product line whereas Procurve are 'J' product line.
Modules for comware switches use standard hardware and need to use comware coding whereas Procurve transceivers contains sophisticated code.
Thanks!
