The EX 4200-48T-DC Ethernet Switch with Virtual Chassis technology combine the High Availability (HA) and carrier-class reliability of modular systems with the economics and flexibility of stackable platforms, delivering a high-performance, scalable solution for data center, campus and branch office environments. Offering a full suite of Layer 2 and Layer 3 switching capabilities as part of the base software, the EX 4200-48T-DC switch satisfy a variety of high-performance applications, including branch, campus and data center access deployments as well as Gigabit Ethernet (GbE) aggregation deployments. A single 48-port switch can be deployed initially; as requirements grow, Juniper Networks Virtual Chassis technology allows up to 10 EX 4200 series 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. Flexible Gigabit Ethernet (GbE) and 10-Gigabit Ethernet (10 GbE) uplink options enable high-speed connectivity to aggregation- or core-layer switches which connect multiple floors.
