I have on Cisco 2960X 24 port switch .Now I want to buy one 48 port switch .I am planing to buy 9200L.
and provide uplink will SFP ( 1Gb ) . Will it work ? ( 2960X computer need to talk with 9200L computer)
2960X cannot be stacked with a 9200L. Both can be connected, using ethernet cable, and they will both act independently.
Adding to @Leo Laohoo comment, good to create a port-channle with 2 Links so you have resiliance.
