Are SFP (mini-GBIC) adapters supposed to be cross vendor compatible? Thread starter ... HP Procurve switches with later versions of firmware will deactivate ports which have non-HP GBIC's in them.

If the mini- GBIC or SFP transceiver is removed before the authentication completes a self test failure will be reported. Caution Use only supported genuine ProCurve mini-GBICs with your switch.
