Product Review

The Juniper EX3400-24P offers a solid combination of 24 PoE+ ports with a high PoE power budget of 370W/720W, supporting devices with substantial power requirements. With the inclusion of 4 SFP+ and 2 QSFP+ uplink ports, it provides flexible uplink connectivity options, accommodating both 10GbE and 40GbE speeds, which enhances its scalability for growing network demands. However, its maximum system power consumption at 110W, coupled with its physical dimensions, may pose challenges for deployment in space-constrained environments or for operations seeking to minimize energy usage.


The Juniper EX3400-24P is a network switch designed for high-performance access applications. It features 24 10/100/1000BASE-T ports, all of which support Power over Ethernet Plus (PoE+) with a total PoE power budget of 370W, expandable to 720W. This allows for flexible deployment of network devices without the need for separate power sources. The switch is equipped with four SFP+ and two QSFP+ uplink ports, facilitating high-speed uplink connections and providing a scalable backbone for growing networks. Key specifications include: - 24 PoE+ ports capable of delivering up to 30W per port. - A backplane capacity of 160 Gbps using QSFP+ ports or 80 Gbps with SFP+ ports, supporting high-speed data transfer and efficient traffic management. - Dual power supply options with an AC power supply type, ensuring uninterrupted operation and system resilience. The power supply rating is 600W, and the maximum system power consumption is 110W under normal conditions. The EX3400-24P's physical dimensions are as follows: the base unit measures 17.36 x 1.72 x 13.78 inches, expanding to 17.36 x 1.72 x 15.19 inches with the power supply and front module installed. This compact size makes it suitable for various installation environments, from small closets to large data centers. The system's weight is 1.82 lb, and the fan module adds an additional 0.16 lb. Designed for efficiency and reliability, the switch operates within a temperature range of 32° F to 113° F and can be stored from -40° F up to 158° F. It supports operation at altitudes up to 10,000 feet and non-operating altitudes up to 16,000 feet. With a relative humidity operational range of 10% to 85% (non-condensing), it ensures consistent performance across various environmental conditions. The acoustic noise level is low at 37 dBA, minimizing distractions in quiet office settings. For network administrators, the Juniper EX3400-24P offers front-to-back airflow, supporting efficient cooling and reliable operation over extended periods. This feature, combined with the switch's robust virtual chassis interconnect capability, allows for scalable network expansions and simplifies management tasks. In summary, the Juniper EX3400-24P is a versatile and efficient switch that meets the demands of modern network environments. Its combination of PoE+ support, high-speed uplink options, and compact, reliable design make it an excellent choice for organizations looking to deploy a flexible and high-performing network infrastructure.
