Juniper EX3400 Ethernet Switch Series – High‑Performance Access Switch

The Juniper EX3400 Ethernet Switch delivers a scalable and flexible access‑layer switching solution built on Juniper’s Junos OS, ideal for enterprise, campus, and converged network environments. Designed to support data, voice, and video traffic efficiently, the EX3400 offers robust Layer 2 switching and optional Layer 3 routing, advanced quality‑of‑service features, and Virtual Chassis technology that allows up to 10 interconnected switches to operate as a single logical unit for simplified management and expanded port density.

Available in 24‑ or 48‑port models—with and without Power over Ethernet/PoE+—the EX3400 provides multiple uplink options including four front‑panel SFP/SFP+ ports for 1 GbE or 10 GbE optics (supporting modules like SFP‑1GE‑LX), and two rear‑panel 40 GbE QSFP+ ports. These flexible uplinks support high‑capacity connectivity to distribution or core layers and can be configured for Virtual Chassis links. The switch’s compact 1 RU form factor, rich feature set (including IEEE 802.1AE MACsec encryption and advanced QoS), and cloud‑ready management with Juniper Mist Wired Assurance further extend its value across enterprise access deployments.

Key Features:
• Flexible access‑layer switching with 24 or 48 10/100/1000BASE‑T ports (PoE/PoE+ support available).
• Four configurable SFP/SFP+ uplink ports for 1 GbE or 10 GbE optics (e.g., SFP‑1GE‑LX).
• Two 40 GbE QSFP+ ports for high‑speed uplinks or Virtual Chassis links.
• Junos OS with advanced Layer 2/Layer 3, QoS, MACsec, and security features.
• Virtual Chassis technology for simplified unified management of up to 10 switches.
