Product Review

The Juniper EX4200-48P-TAA offers a high-density configuration with 48 PoE+ ports and a 930 W AC power supply, supporting demanding power requirements for connected devices. Its Virtual Chassis technology allows up to 10 units to be interconnected, creating a single logical device with a 128 Gbps backplane, enhancing scalability and simplification of management. However, it generates considerable noise at 54.0 dBA, which may be a concern in quieter office environments.


The Juniper EX4200-48P-TAA is a Trade Agreement Act-compliant networking switch designed for optimal performance and efficiency in various environments. This device features 48 10/100/1000BASE-T ports, all of which support Power over Ethernet Plus (PoE+), providing flexibility and simplifying the network infrastructure by eliminating the need for additional power cables for connected devices. Powering the EX4200-48P-TAA is a 930 W AC power supply unit (PSU), ensuring sufficient power for both the switch itself and the PoE+ capabilities across all ports. The inclusion of a 50cm Virtual Chassis cable allows for the interconnection of up to 10 units, creating a single logical device with a backplane capacity of 128 Gbps. This scalability feature is particularly beneficial for growing networks that require seamless expansion without the complexity of adding new management points. Key hardware specifications include: - <>
  • Access Port Configuration: 48-port 10/100/1000BASE-T
  • Power Supply Rating: 930 W AC
  • Packet Switching Capacities: 136 Gbps
The switch occupies 1 rack unit (RU) in height, with dimensions of 17.41 x 1.72 x 16.43 inches (44.21 x 4.32 x 41.73 cm) for desktop installation. Rack-mount width is slightly larger at 17.5 inches (44.5 cm). Depending on the chosen PSU, the depth can extend to 18.8 inches (47.8 cm) when equipped with a 600/930 W AC PSU. The system's total weight is 17.2 pounds (7.8 kg), making it relatively easy to handle during installation or maintenance. The EX4200-48P-TAA is designed to maintain a low noise output with an acoustic noise level of 54.0 dBA, minimizing distraction in work environments. Airflow is rated at 20.3 cubic feet per minute (cfm), ensuring adequate cooling for continuous operation. Operational efficiency is further evidenced by the switch's packet switching capacity of 136 Gbps and a throughput of 101 million packets per second (Mpps), facilitating wire-speed performance across all ports. Environmental tolerance is a key consideration in the design of the EX4200-48P-TAA. It operates within a temperature range of 32° F to 113° F and can be stored in temperatures ranging from -40° F to 158° F. The switch can function at altitudes up to 10,000 feet (3,049 m) when operational and up to 16,000 feet (4,877 m) when not in use. Relative humidity tolerance during operation ranges from 10% to 85% non-condensing, ensuring reliability across various environmental conditions. In summary, the Juniper EX4200-48P-TAA is a versatile and scalable networking switch that caters to the demands of modern networks. Its comprehensive feature set, including full PoE+ support across all ports, a robust power supply, and the ability to form a single logical device through Virtual Chassis technology, make it an ideal solution for organizations looking to optimize their network infrastructure for performance and efficiency.
