The EX4300 Ethernet switches are compact platforms with fixed configuration that meet the demands of a variety of high-performance branch office, campus, and data center access deployments. Juniper's Virtual Chassis technology allows for the connection of up to 10 EX4300 switches via a 320 Gbps backplane with four 40 GbE ports on the rear. This creates a single, logical device that provides a highly scalable and cost-effective solution for growing campus environments. It also supports five-part complete Virtual Chassis configurations with a span of up to 150 meters. This offers a low-latency solution, ensuring that the distance between switch members is very short. The EX4300 switches support 10/100/1000BASE-T models with 24 or 48 ports. EX4300 models with Power over Ethernet (PoE) provide standard-based 802.3at PoE+.
