Wire-speed performance at high 1GbE, 10GbE, and 40GbE port densities dramatically simplifies network topologies and operations.
3. 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.
4. 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.
5. Virtual Chassis
Virtual Chassis technology allows multiple interconnected switches to operate as a single logical device, reducing operational expenses and simplifying management.
6. 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.

Frequently Asked Questions
What is the primary purpose of the Juniper EX4300-48P-VHBRSN in a network environment? +
The EX4300-48P is a high-performance, managed Layer 3 switch designed for enterprise campus deployments. It provides 48 ports of 10/100/1000BaseT connectivity with PoE+ support, making it an ideal choice for powering VoIP phones, wireless access points, and surveillance cameras while ensuring robust switching fabric capacity for demanding network traffic.
How much power does the EX4300-48P provide for PoE+ devices? +
This model comes equipped with a high-capacity 1100W AC power supply. This ensures that you have significant power overhead to support full PoE+ (802.3at) capabilities across all 48 ports simultaneously, assuming standard power draw requirements for your connected peripherals and endpoints in an enterprise branch or campus setting.
Can the EX4300-48P be managed through Juniper's Virtual Chassis technology? +
Yes, the EX4300-48P supports Juniper’s Virtual Chassis technology, allowing you to interconnect multiple switches to function as a single, logical device. This simplifies management and increases port density, providing high availability and easier configuration across your network stack without needing to manage each individual unit separately.
What type of port density does the EX4300-48P offer for data-heavy applications? +
The unit features 48 dedicated 10/100/1000BaseT RJ45 ports. These ports provide reliable gigabit speeds for end-user connectivity. Furthermore, the EX4300 series architecture is built to support high-speed uplinks, allowing for flexible configuration to meet your specific throughput needs when aggregating traffic from the access layer to the core or distribution layers.
Is the EX4300-48P suitable for modern office VoIP and security camera deployments? +
Absolutely. With its integrated PoE+ support and robust Layer 3 capabilities, this switch is engineered to handle the converged traffic of modern offices. It delivers the necessary power and traffic prioritization features, such as Quality of Service, to ensure that latency-sensitive voice and high-bandwidth security video streams remain stable and secure.
What is the form factor of this Juniper switch? +
The EX4300-48P is designed as a rackmount unit, fitting standard 19-inch server racks. Its compact 1U height saves valuable rack space while maintaining the airflow and thermal management required for dense, high-performance network environments.
