Juniper EX4300 Ethernet Switch

Spectra buys and sell used and refurbished Juniper EX series Networking products. We offer an industry leading 90 day warranty on all Juniper products.

The EX4300 Multigigabit Ethernet Switch is a high-performance switch for advanced branch or campus deployments.

The Juniper EX4300 Ethernet Switch utilizes Virtual Chassis technology that enables any combination of up to 10 EX4300, QFX3500, QFX3600, and QFX5100 switches to be interconnected as a single logical device that delivers a cost effective and highly scalable solution for 1GbE or mixed 1GbE/10GbE/40GbE environments. The Juniper EX4300 Ethernet Switch can also be used in a QFX5100-based Virtual Chassis Fabric switching architecture, which enables up to 20 interconnected EX4300, QFX3500, QFX3600, and QFX5100 switches to operate as a low-latency, high-performance 1GbE/10GbE/40GbE data center fabric that is managed as a single device.

Since 1982, Spectra is your global source for used and refurbished Juniper Networks Switches!
