The SN4600 is a 2U, 64-port 200GbE spine switch that can also function as a high-density leaf switch. When used with breakout cables, it can be fully split into 128 ports of 10/25/50GbE. The SN4600 offers exceptional flexibility with port speeds ranging from 1GbE to 200GbE. Its port density enables connectivity to any server within the rack at any speed, while supporting multiple oversubscription ratios.
