hii have fibers with cisco transeiver 1000base-sx 30-1299-3 850nm. they works well when they are plugged in nexus-3548 switch.i try to use the same fibers plugged in a new cbs220-24P-4X switch, but now it does not workdo you know why ?thanks
i already did it, and see that cbs220 is compatible with transeiver GLC-SX-MMDbut may be 1000base-sx 30-1299-3 850nm is not GLC-SX-MMD transeiver ? if not what king of transeiver is it ?
