Offering a full suite of Layer 2 and Layer 3 switching capabilities as part of the base software, the EX 4200 series switches 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 24-port or 48-port switch can be deployed initially; as requirements grow, Juniper 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 or buildings. All EX 4200 series switches include HA features such as redundant, hot-swappable internal power supplies and field-replaceable, multi-blower fan trays to ensure maximum uptime.
