MPN: EX3400-48P·By: Juniper
Ships worldwide from the US.
The Juniper Networks EX3400-48P is a high-performance Layer 2/3 Ethernet switch designed for enterprise access, campus aggregation, and branch deployments. It features 48x 10/100/1000BASE-T PoE+ ports delivering up to 30W per port (3360W total PoE budget), 4x 1/10GbE SFP/SFP+ uplinks, and 2x 40GbE QSFP+ uplinks for flexible high-speed connectivity. Supporting Virtual Chassis technology, up to 10 switches interconnect as a single logical device for simplified management and scalability. With 288 Gbps switching capacity, wire-speed L3 routing (OSPF, BGP, VRF), and Junos OS features like MACsec encryption, it ensures low-latency performance for dense user environments. Redundant fans and hot-pluggable PSU enable high availability, while compact 1RU design fits standard racks. Ideal for powering VoIP phones, WLAN APs, and IP cameras in cost-effective, resilient networks.

Native Virtual Chassis with other EX3400; Junos OS; standard SFP/QSFP+ optics.
Virtual Chassis up to 10 units
Powers 48 PoE+ devices like WiFi APs and VoIP phones in university or office wiring closets.
Delivers high-density Gigabit PoE with 40G uplinks for retail or remote office connectivity.
Provides L3 routing and Virtual Chassis scaling for server access layers.
Aggregates multiple access switches via 40GbE QSFP+ for campus core distribution.
Supports high-power PoE cameras and NVRs with 3360W budget in security deployments.
High-port density for wireless access points in dense enterprise environments.
The EX3400-48P supports IEEE 802.3at PoE+ on all 48x 10/100/1000BASE-T ports with a 3360W total budget, delivering up to 30W per port. This enables powering high-demand devices like multi-radio WiFi 6 APs, PTZ cameras, and VoIP phones simultaneously in dense access environments.
It includes 4x 1/10GbE SFP/SFP+ ports and 2x 40GbE QSFP+ ports (optics sold separately). QSFP+ ports support breakout to 4x10GbE, providing flexible non-blocking uplinks to aggregation or core layers with 288 Gbps total capacity.
Yes, Virtual Chassis technology interconnects up to 10 EX3400 switches into a single logical device managed via one IP address. This simplifies cabling, enhances resiliency with hitless failover, and scales port density for campus or data center access.
Full L3 routing includes OSPF, BGP, IS-IS, RIP, static routes, VRF-Lite, and VRRP redundancy. Hardware supports thousands of IPv4/IPv6 routes with wire-speed forwarding, ideal for routed access or collapsed core designs.
Runs Junos OS with CLI, Web UI, J-Web, SNMP, and NETCONF/YANG APIs. Supports Zero Touch Provisioning (ZTP), Junos Space, and Mist AI integration for automated deployment and analytics in enterprise networks.
Ships with 1x hot-pluggable AC PSU (JPSU-150-ACAFO) supporting redundant operation. Features redundant variable-speed fans with back-to-front airflow for efficient cooling in standard 19-inch racks.
