Juniper Networks EX4300 Ethernet Switch

Category:

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 EX4600switches 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 Enterpriseor 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.

EX4300 Features

SDN Orchestration from the Cloud
Contrail Service Orchestration provides software-defined configuration, management, and orchestration, centrally from the cloud.

AI-driven Wired Assurance
Using unified wired-wireless LAN telemetry, the Mist AI engine enables SLAs, anomaly detection, and smart troubleshooting chain for root-cause analysis across the wired and wireless network.

Field-Proven Juniper Technology
A cloud-grade architecture, coupled with the Junos OS, enables EX Series switches to provide always-on reliability for every application.

Wire-Speed Performance
Wire-speed performance at high 1GbE, 10GbE, and 40GbE port densities dramatically simplifies network topologies and operations.

Eight QoS Queues
Eight QoS queues per switch port ensure proper prioritization of voice, video, and multiple levels of data traffic, with room to converge other networks, such as building automation and video security systems.

Innovative Switch Design
Innovative, cost-effective switch design enables new architectures that reduce cost and complexity, while unified management and automation tools consolidate system monitoring.

Virtual Chassis
Virtual Chassis technology allows multiple interconnected switches to operate as a single logical device, reducing operational expenses and simplifying management.

Near Line-Rate Encryption
Support for IEEE 802.1ae Media Access Control Security (MACsec) for link-layer data confidentiality, data integrity, and data origin authentication enables 88 Gbps of near line-rate, hardware-based traffic encryption on all 1GbE and 10GbE ports.
