I have Supermicro switch with CX4 module hooked in the back panel of SSE-G24-TG4 model. I want to know if there is a part number for purchasing CX4 to CX4 cable from Supermicro?
Yes. CBL-0389L is the part number for CX4 to CX4 (3 meters) cable. Also, it's not recommended to use more than 3 meters length for CX4 in “stacking” as normal industry standard.
