The EX4300 switches are fixed-configuration platforms that satisfy a variety of high-performance campus and data center access needs. They offer IEEE 802.3af Power over Ethernet (PoE) or 802.3at PoE+ ports up to 30W.

The EX4300 is cloud-ready and ZTP-enabled, so you can onboard, configure, and manage it with Juniper Mist™ Wired Assurance for improved connected-device experiences. In addition, the Juniper Mist Cloud streamlines deploying and managing your campus fabric, while Mist AI simplifies operations and improves visibility into the performance of connected devices. EX4300 switches support Juniper’s Virtual Chassis technology, enabling any combination of up to 10 EX4300 and EX4600 switches to be interconnected and managed as a single logical device for a highly scalable, cost-effective solution in 1GbE or mixed 1GbE/10GbE/40GbE environments.
