Overview

  • EX4300 1 Gigabit Ethernet (1GbE) switches are compact, fixed-configuration platforms that can be deployed as standalone systems or as part of a Virtual Chassis, Virtual Chassis Fabric, or Junos Fusion switching architecture, satisfying a variety of high-performance campus and data center access needs.
  • Virtual Chassis technology enables any combination of up to 10 EX4300 and EX4600 switches to be interconnected as a single logical device, delivering a highly scalable, cost-effective solution for 1GbE or mixed 1GbE/10GbE/40GbE environments.
  • The EX4300 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.
  • Additionally, the EX4300 can be deployed as satellite device in a Junos Fusion Enterprise or Junos Fusion Data Center fabric, which enables up to 128 access switches to be managed as a single logical device.
  • The EX4300 line features 24 and 48-port 10/100/1000BASE-T models and a 32-port 100BASE-FX/1000BASE-X SFP model. On the fiber-based switches, four fixed front-panel uplink ports accommodate 1GbE or 10GbE optics for high-speed backbone or link aggregation connections. The four 40GBASE quad small form-factor pluggable plus transceiver (QSFP+) ports available on each model can also be used for high-speed backbone or link aggregation connections. 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, surveillance camera, or wireless access point deployments.
