Juniper

Specifications

Description:

The Juniper EX3400-48P is a Layer 2 and Layer 3 Gigabit Ethernet switch with 48 PoE+ ports, designed to meet the performance, power, and scalability demands of modern enterprise networks. With a 740W PoE budget, 4x 10GbE SFP+, and 2x 40GbE QSFP+ uplinks, this switch supports a wide range of deployment scenarios including access, aggregation, and high-throughput edge networking.
Operating on Junos OS, the EX3400-48P supports Virtual Chassis, enabling seamless management of multiple interconnected units as one logical device. It is built for flexibility, efficiency, and dense environments like campus networks, offices, and distributed branches.

Features:

48x PoE+ RJ-45 ports (10/100/1000BASE-T), supplying up to 30W per port for devices like access points, IP phones, and security cameras.
4x 10GbE SFP+ uplinks for high-speed backbone or server connectivity.
2x 40GbE QSFP+ uplinks, supporting high-throughput aggregation or stacking.
740W PoE budget, easily powering dozens of devices without external power injectors.
336 Gbps switching capacity and 250 Mpps forwarding rate for wire-speed performance.
32,000 MAC address entries, supporting large-scale, multi-device environments.
Virtual Chassis support with up to 10 interconnected switches.
Front-to-back airflow for compatibility with data center cooling setups.
Modular power and fan support, enhancing redundancy and uptime.
