What PoE capabilities does the EX3400-48P provide?

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.

What is the uplink configuration on EX3400-48P?

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.

Does EX3400-48P support Virtual Chassis?

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.

What Layer 3 features are available?

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.

What management options does it offer?

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.

What are the power and airflow options?

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.
