The Juniper Networks EX4300 line of Ethernet switch with Virtual Chassis technology combines the 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, the EX4300 satisfies a variety of high-performance applications, including branch, campus, and data center access deployments as well as Gigabit Ethernet (GbE) access deployments. As requirements grow, Juniper Networks Virtual Chassis technology allows up to 10 EX4300 switches to be interconnected and managed as a single device, delivering a scalable, pay-as-you-grow solution for expanding network environments. The EX4300 switch can be interconnected over multiple 40GbE quad small form-factor pluggable plus (QSFP+) transceiver ports to form a 320 gigabits per second (Gbps) backplane.
EX4300 switch includes high availability (HA) features such as redundant, hot-swappable internal power supplies and field-replaceable fans to ensure maximum uptime.
