Silver rack-mountable network switch with 24 front ports and four QSFP+ uplinks

HPE Juniper Networking

HPE Juniper Networking EX4300-24P 24-port managed network switch

SKU CH-8BS9-RT6JT

A 24-port managed Gigabit PoE+ switch with four 40 Gbps QSFP+ uplinks and Virtual Chassis stacking for up to 10 units

  • 24 PoE+ ports power access points and IP phones directly
  • Four 40 Gbps QSFP+ uplinks aggregate high-speed backbone traffic
  • Virtual Chassis unifies up to 10 switches into one managed device
  • 320 Gbps backplane capacity handles growing campus and data-centre loads
  • Redundant hot-swap power supplies and field-replaceable fans maximise uptime

24-port managed switch with 40 GbE uplinks

The Juniper Networks EX4300-24P is a rack-mountable managed switch designed for campus, branch and data centre access deployments. It provides twenty-four 10/100/1000 PoE+ ports and four 40 Gigabit QSFP+ uplinks. Up to ten units can be linked with Virtual Chassis technology and managed as a single device.

Thermals and power

Front-to-back airflow matches standard rack cooling layouts. Redundant hot-swappable internal power supplies and field-replaceable fans maintain service continuity during hardware replacement. The PoE+ budget powers attached endpoints such as wireless access points or IP phones without external injectors.

Virtual Chassis and high availability

Virtual Chassis interconnects up to ten switches over the 40 GbE ports to form a 320 Gbps backplane, simplifying management and scaling bandwidth. Redundant power supplies and swappable fans reduce downtime risk during component failure. Layer 2 and Layer 3 feature sets support diverse access and aggregation roles.

Questions about this item

How do I install the EX4300-24P in a rack and what is the common airflow mistake?

Mount the switch using the included rack ears with front-to-back airflow orientation; the step often missed is verifying that cold-aisle air enters the front vents and hot exhaust leaves the rear, otherwise the field-replaceable fans cannot cool the 24 PoE+ ports and four 40 Gbps QSFP+ uplinks.

Which components will need replacement during the life of the EX4300-24P?

The hot-swappable internal power supplies and the field-replaceable fan modules are the only parts designed for in-service replacement; both can be swapped without powering down the switch or disrupting the Virtual Chassis of up to 10 interconnected units.

What throughput limit appears first when the EX4300-24P runs sustained traffic?

The 320 Gbps Virtual Chassis backplane shared across the four 40 Gbps QSFP+ uplinks becomes the bottleneck before the 24 10/100/1000 PoE+ access ports, capping aggregate inter-switch bandwidth in a fully stacked deployment.
