SFP (J4858B) not recognized by module (J8706A) on insert

[MichaelvLonden]

Hi,

I've got two 8212 switches (fw K.15.10.0013m), both with two 24-ports SFP module (J8706A)

When I insert SFP (J4858B) in switch 1 in one of 24-ports modules, SPF is not recognized at all (type field is empty and not showing 1000SX as expected).

When I put the same SPF in switch 2, in the same type of module, SFP is recognized as expected.

What can cause issue and how do I solve this, without restarting module or switch?

Kind regards,

Michael

Hi Michael,

Are both your SFP port modules v2? A (B) transceiver is quite an old revision now. See below Matrix table for compatibility...

I take it no matter which SFP port you plug the transceiver in to on Switch 1 it is not recognised?
