Product Review

The Juniper EX4200-48T offers a high-density configuration with 48 10/100/1000BASE-T ports, including 8 PoE ports, and a backplane capacity of 128 Gbps, allowing up to 10 units to be interconnected for scalable network designs. However, its power over Ethernet (PoE) budget is limited to 130 W, restricting the number of high-power devices it can support simultaneously. Additionally, the switch operates with significant acoustic noise at 51.6 dBA, which could be a consideration for environments where noise levels are a concern.


The Juniper EX4200-48T is a switch designed for high-performance networking, offering 48 10/100/1000BASE-T ports, including 8 ports with Power over Ethernet (PoE) capability. This device is engineered to facilitate efficient network connectivity and power supply for connected devices. It comes with a 320W AC power supply unit (PSU) and is accompanied by a 50cm Virtual Chassis cable to enable easy integration with other units. Key hardware specifications of the EX4200-48T include a compact form factor of 1 rack unit (RU) height, providing a dense, space-efficient solution for network racks. The switch supports a PoE budget of 130W, sufficient for powering multiple PoE-enabled devices without the need for additional power sources. Despite its compact size, the unit boasts a substantial power supply rating of 320W AC, ensuring reliable operation under various load conditions. The networking capabilities of the EX4200-48T are enhanced by its backplane, which offers a 128Gbps Virtual Chassis interconnect. This feature allows up to 10 units to be combined, functioning as a single logical device, thereby simplifying network management and scalability. The switch is designed to handle a maximum current inrush of 50 amps, highlighting its robust power handling capabilities. Dimensions of the EX4200-48T are tailored for both desktop and rack-mount installations, with a width of 17.41 inches (44.21 cm), a height of 1.72 inches (4.32 cm), and a depth of 16.43 inches (41.73 cm) for the standard setup. When equipped with larger PSUs, the depth extends to 18.8 inches (47.8 cm). The system weight is 17.1 lb (7.8 kg), making it relatively lightweight for installation and maintenance. In terms of performance, the EX4200-48T delivers a packet switching capacity of 136Gbps and a throughput of 101 million packets per second (Mpps), ensuring wire-speed performance across all ports. The system's airflow is rated at 20.3 cubic feet per minute (cfm), with an acoustic noise level of 51.6 dBA, striking a balance between cooling efficiency and noise control.
  • GbE port density per system is 52, which includes 48 host ports and a four-port GbE uplink module.
