Best Fit Applications

High-Density Enterprise Campus Access

The EX3400-48T provides 48 non-PoE Gigabit Ethernet ports, four 1/10GbE uplinks, and two 40GbE QSFP+ ports for high-density enterprise campus access.

Non-PoE Wiring Closet Deployments

With 48 Gigabit Ethernet ports and no PoE power requirement, the EX3400-48T is suitable for access-layer deployments where connected devices use independent power sources.

High-Speed Aggregation Uplinks

Four dual-mode SFP/SFP+ uplinks and two 40GbE QSFP+ ports provide high-speed connectivity to distribution, aggregation, and Virtual Chassis networks.

Virtual Chassis Deployments

Up to 10 EX3400 switches can be interconnected and managed as a single logical device for scalable campus access and simplified operations.

Why EX3400-48T

High Port Density Without PoE Overhead

The EX3400-48T provides 48 Gigabit Ethernet access ports for deployments that do not require power delivery over Ethernet, helping reserve the switch budget for data access and uplink capacity.

Redundant and Hot-Swappable Hardware

The switch supports two hot-swappable power supplies and two hot-swappable fan modules for improved serviceability and hardware redundancy.

Hardware-Based MACsec Security

IEEE 802.1AE MACsec provides hardware-based link-layer confidentiality, data integrity, and data-origin authentication across supported Gigabit Ethernet and 10GbE ports.
