transeiver cisco 30-1299-3 850nm do not work with cbs220 switch

hi
i 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 work
do you know why ?
thanks

i would go and check the support matrix :

i already did it, and see that cbs220 is compatible with transeiver GLC-SX-MMD
but may be 1000base-sx 30-1299-3 850nm is not  GLC-SX-MMD transeiver ? if not what king of transeiver is it ?

some of the SX-MM not works on new hardware.
