EX4300-48P Overview
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.

Frequently Asked Questions
Is the Juniper EX4300-48P available refurbished? +
Yes. This page lists the refurbished condition currently available from BuyRouterSwitch. Availability can change, especially for bulk orders.
Can I request bulk pricing for EX4300-48P? +
Yes. Businesses, resellers, MSPs, government buyers and procurement teams can request custom quantity pricing.
Does BuyRouterSwitch ship EX4300-48P internationally? +
BuyRouterSwitch ships enterprise IT hardware to customers in the United States and international markets, subject to destination and product restrictions.
What is the total PoE budget for the Juniper EX4300-48P when using the 1100W AC power supply? +
The EX4300-48P includes an 1100W AC power supply, which provides significant power to support high-density PoE+ deployments. This unit is designed to deliver full 802.3at PoE+ power across all 48 ports simultaneously, ensuring your IP phones, high-performance wireless access points, and security cameras receive the consistent wattage required for enterprise-grade network operations without performance degradation.
Can the EX4300-48P be integrated into a Virtual Chassis configuration? +
Yes, the EX4300-48P is fully compatible with Juniper's Virtual Chassis technology. You can interconnect up to 10 switches into a single logical device, simplifying management and providing high-density port configurations. This allows for a flexible, scalable architecture that can grow alongside your data center or campus networking requirements, all while maintaining unified control and simplified configuration.
Does the EX4300-48P support 10GbE uplink capabilities? +
The EX4300-48P series features fixed front-panel ports for 1GbE access, but it is designed with modular uplink capabilities. You can utilize the dedicated uplink slots to install optional expansion modules that support 10GbE SFP+ or 40GbE QSFP+ transceivers. This modular approach allows you to scale your uplink bandwidth as your traffic demands increase over time.
What is the primary use case for the Juniper EX4300-48P in an enterprise environment? +
This switch is an ideal choice for campus wiring closets and data center top-of-rack deployments. With its 48 ports of 10/100/1000BaseT PoE+, it is specifically built for high-density environments requiring reliable connectivity for powered end-points. Its robust feature set and manageability make it perfect for organizations seeking a stable, secure foundation for converged voice, video, and data traffic.
How do I manage the EX4300-48P within my existing network infrastructure? +
Management is handled through the Junos OS, which offers a consistent CLI for advanced granular control. Additionally, for streamlined operations, you can utilize the Juniper Networks J-Web interface for graphical management or integrate the switch into Junos Space for centralized network orchestration. This dual-approach ensures that both power users and administrators requiring simplified views can manage the device effectively.
Is the EX4300-48P suitable for Layer 3 routing applications? +
The EX4300-48P supports a comprehensive range of Layer 3 protocols, including OSPF, BGP, and IS-IS, allowing it to function effectively as a core or distribution layer switch. With high-performance switching capacity, it handles advanced routing tasks efficiently, ensuring low-latency packet delivery across your routed network segments without the need for additional specialized routing hardware.
What type of power redundancy options are available for this specific EX4300 model? +
The EX4300-48P is designed with hot-swappable power supply slots, allowing for field-replaceable power redundancy. By installing a second 1100W AC power supply, you can achieve N+1 power redundancy, ensuring your critical network infrastructure remains operational even in the event of a single power source failure. This redundancy is essential for maintaining uptime in mission-critical office environments.
What are the cooling requirements for the EX4300-48P when rack-mounting? +
The EX4300-48P utilizes a field-replaceable, redundant fan module system to ensure consistent airflow and thermal management. For proper operation, you should ensure the rack has sufficient ventilation and clear intake/exhaust paths. Because the switch features front-to-back or back-to-front airflow options depending on the chosen fan tray, it is adaptable to both cold-aisle and hot-aisle containment strategies common in modern data centers.
