The Juniper EX 4200 Ethernet Switch satisfies a variety of high-performance applications, including branch, campus and data center access deployments as well as Gigabit Ethernet (GbE) aggregation deployments. A single 24-port or 48-port switch can be deployed initially; as requirements grow, Juniper EX 4200 Ethernet Switch Virtual Chassis technology allows up to 10 EX 4200 Ethernet Switch switches to be interconnected over a 128 gigabit-per-second (Gbps) backplane and managed as a single device, delivering a scalable, pay-as-you-grow solution for expanding network environments.
