Product Description

EX4300-48T - 48-port 10/100/1000BASE-T, 350W AC, 1U

EX4300 Ethernet switches are compact, fixed-configuration platforms that satisfy a variety of high-performance branch, campus and data center access deployments.

Juniper Virtual Chassis technology enables up to 10 EX4300 switches to be interconnected over a 320 Gbps backplane using four back-panel 40GbE ports, creating a single, logical device that delivers a highly scalable, cost-effective solution for growing campus environments. Five-member full-mesh Virtual Chassis configurations spanning up to 150 meters are also supported, delivering a low-latency solution that ensures switch members are just one hop away from every other switch.

The EX4300 switches support 10/100/1000BASE-T with both 24- and 48-port models. Power over Ethernet (PoE)-enabled EX4300 models offer standards-based 802.3at PoE+, delivering up to 30 watts on all ports for supporting high-density IP telephony and 802.11n wireless access point deployments. A dual-purpose four-port GbE/10GbE fiber uplink module is also available.
