Product Review

The Juniper EX4200-24T offers a solid option for network expansion with its 24 10/100/1000BASE-T ports, including 8 PoE ports, supporting diverse connectivity requirements. The device's ability to combine up to 10 units with a 128 Gbps Virtual Chassis interconnect enhances scalability and operational flexibility. However, its 51.6 dBA acoustic noise level may be a drawback in quieter working environments, and the limited PoE budget of 130W could restrict power distribution for connected devices.


The Juniper EX4200-24T is a network switch designed to cater to the demands of high-performance networking requirements. This switch features a 24-port configuration, providing 10/100/1000BASE-T connectivity. Among these, 8 ports are enabled with Power over Ethernet (PoE), allowing for direct electrical power transmission along with data over the network cables to PoE-enabled devices. This functionality simplifies the cabling process for devices like IP cameras and VoIP phones by eliminating the need for separate power sources. This device stands at 1 Rack Unit (RU) in height, making it compact enough for efficient use in both small and large data center environments. The switch has a power supply rating of 320 W AC and supports a PoE budget of 130 W, ensuring sufficient power distribution for connected PoE devices. Additionally, it comes with a 50cm Virtual Chassis cable, enabling the interconnection of up to 10 units. This capability allows for the creation of a single logical device from multiple units, simplifying management and operational processes. In terms of performance, the EX4200-24T offers a backplane capacity of 128 Gbps, facilitating high-speed data transfer and efficient packet switching across the network. The system's packet switching capacities reach up to 88 Gbps, with a throughput rate of 65 Mpps (million packets per second), ensuring wire-speed performance across all ports. The physical dimensions of the switch are 17.41 x 1.72 x 16.43 inches (44.21 x 4.32 x 41.73 cm) for desktop installation, with a slight increase to 17.5 inches (44.5 cm) in width for rack-mount setups. Depending on the power supply unit installed, the depth can extend to 18.8 inches (47.8 cm) with higher capacity PSUs. The system's weight is 16.5 lb (7.5 kg), making it manageable for installation and maintenance activities. For environments concerned with noise levels, the EX4200-24T operates with an acoustic noise level of 51.6 dBA. It also features an airflow rate of 20.3 cubic feet per minute (cfm), ensuring adequate cooling for the system during operation. The operational temperature range is from 32°F to 113°F, with a storage temperature range extending from -40°F to 158°F. The device can operate at altitudes of up to 10,000 ft (3,049 m) and be stored at altitudes up to 16,000 ft (4,877 m), with a relative humidity tolerance of 10% to 85% (noncondensing). Key highlights include: - 24-port 10/100/1000BASE-T configuration with 8 PoE ports - Virtual Chassis technology enabling up to 10 units to function as a single logical device - 65 Mpps throughput for high-performance packet switching The Juniper EX4200-24T is designed to meet the needs of today's high-demand network environments, providing a scalable, high-performance networking solution.
