Product Review

The Juniper EX3400-48P offers a comprehensive solution for high-density networking environments, supporting 48 PoE+ ports with a significant PoE power budget of up to 1440W, ideal for powering a wide range of devices. With the inclusion of both 10GbE SFP+/SFP and 40GbE QSFP+ uplink ports, it provides flexible uplink capabilities, ensuring scalability and connectivity for high-speed networking requirements. However, its maximum system power consumption of 120W and a relatively large footprint might pose challenges in power-limited or space-constrained deployments.


The Juniper EX3400-48P is a high-performance Ethernet switch designed for enterprise networks. It features 48 10/100/1000BASE-T ports, all of which support Power over Ethernet Plus (PoE+) with a total PoE power budget of 740W, which can be expanded to 1440W. This switch is equipped with advanced hardware capabilities to support complex network environments and demands. With its 48 PoE+ ports, the EX3400-48P can deliver up to 30W per port, enabling it to power a wide range of PoE devices such as IP cameras, VoIP phones, and wireless access points directly through the network cables, simplifying deployment and reducing the need for additional power supplies. The switch is powered by an AC power supply with a rating of 920W, ensuring sufficient power for both the switch's operations and the connected PoE devices. For high-speed uplink connections, the EX3400-48P includes four SFP+ ports and two QSFP+ ports. These uplink ports provide flexible connectivity options, supporting both 10GbE/GbE for SFP+/SFP modules and 40GbE for QSFP+ modules, facilitating high-speed connections to other network devices or aggregation layers. - Total 10/100/1000BASE-T Ports: 48 PoE+ - Uplinks: 4 10GbE/GbE SFP+/SFP ports and 2 40GbE QSFP+ ports - PoE+ Power Budget: 740W/1440W The backplane capacity of the EX3400-48P is 160 Gbps when using QSFP+ ports or 80 Gbps with SFP+ ports, supporting a Virtual Chassis interconnect to link multiple units. This feature enables the switch to operate efficiently in large-scale networks by facilitating easy management and scalability. The switch's maximum system power consumption is 120W, and it is designed with front-to-back airflow, optimizing cooling for high reliability and continuous operation in data center environments. The unit's dimensions vary slightly depending on the configuration, with the base unit measuring 17.36 x 1.72 x 13.78 inches and slightly larger dimensions when the power supply and front module are installed. Durability and reliability are further evidenced by the operating temperature range of 32°F to 113°F and the storage temperature range of -40°F to 158°F. The EX3400-48P can operate at altitudes up to 10,000 feet and can be stored at altitudes up to 16,000 feet, ensuring operational reliability in a wide range of environmental conditions. The packet-switching capacities of the EX3400-48P reach 168 Gbps unidirectional or 336 Gbps bidirectional, supporting high-volume data traffic without bottlenecks. This, combined with a GbE port density of 54 per system, makes the EX3400-48P a powerful solution for demanding network environments.
