Best Fit Applications

Campus Wiring Closets and PoE Access

24 PoE+ Gigabit ports and 4 × 40GbE QSFP+ ports fit high-density campus access and uplink needs.

Large Branch Office Access

24 PoE+ ports, replaceable fans, and hot-swappable power support reliable branch access.

Data Center Top-of-Rack Access

Four 40GbE QSFP+ ports and 448 Gbps switching support compact top-of-rack access.

Virtual Chassis Interconnection

Connect up to 10 EX4300 switches using QSFP+ or optional SFP+ VCP links.

Why EX4300-24P

PoE+ Capacity for Powered Access Devices

All 24 built-in 10/100/1000BASE-T ports support IEEE 802.3at PoE+ with up to 30W per port, allowing one switch to provide both data connectivity and power for compatible endpoints.

Native 40GbE Uplink and VC Options

Four built-in QSFP+ ports support 40GbE connectivity and can also be configured as Virtual Chassis Ports. This gives the EX4300-24P a defined path for high-speed uplinks or switch interconnection.

Expandable SFP/SFP+ Connectivity

The optional EX-UM-4X4SFP provides four ports that can house SFP transceivers, SFP+ transceivers, or a combination of both. The module can also be used for Virtual Chassis or Virtual Chassis Fabric connections when configured as VCPs.

Serviceable Power and Cooling

The EX4300-24P supports hot-removable and hot-insertable power supplies, while its two fan modules are field-replaceable. The default configuration uses front-to-back AFO airflow components.
