Product Review

The Juniper EX4200-48P offers high density with 48 PoE+ ports and a 128 Gbps Virtual Chassis interconnect, allowing for scalability by combining up to 10 units. However, its power consumption and heat output may be concerning, with a 930W AC power supply and an operating temperature up to 113°F. Additionally, the switch provides robust packet switching capacities at 136 Gbps and a throughput of 101 Mpps, supporting efficient data handling and network performance.


The Juniper EX4200-48P is a network switch designed for high-performance, scalable environments. It features 48 10/100/1000BASE-T ports, all of which support Power over Ethernet (PoE+), providing flexibility and power to connected devices such as VoIP phones, wireless access points, and IP cameras. This switch is equipped with a 930W AC power supply unit (PSU), ensuring adequate power for all PoE+ ports and system operations. It also includes a 50cm Virtual Chassis cable, enabling the interconnection of up to 10 units to function as a single, logical device, thereby simplifying management and operational demands. The device is designed for efficiency and high capacity with a backplane speed of 128 Gbps, facilitating rapid data transfer across the Virtual Chassis configuration. Its packet switching capacities reach up to 136 Gbps, and it can process up to 101 million packets per second (Mpps), ensuring wire-speed throughput across all ports. Key specifications include: - Access Port Configuration: 48-port 10/100/1000BASE-T - PoE Ports: 48 PoE+ - Height: 1 Rack Unit (RU) The EX4200-48P measures 17.41 inches in width, 1.72 inches in height, and 16.43 inches in depth for desktop installation, with a slight increase to 17.5 inches in width for rack-mount configurations. The depth extends to 18.8 inches when equipped with the 600/930W AC PSU. The system's weight is recorded at 17.2 pounds, making it relatively lightweight for its capabilities. Airflow through the system is maintained at 20.3 cubic feet per minute (cfm), with an acoustic noise level of 54.0 dBA, balancing performance with a relatively quiet operation. It is designed to operate within a broad range of temperatures, from 32°F to 113°F, and can be stored in environments ranging from -40°F to 158°F. The operating altitude reaches up to 10,000 feet, with non-operating altitudes extending up to 16,000 feet, and it can operate in relative humidity levels from 10% to 85%, non-condensing. The EX4200-48P is engineered for durability and performance in demanding network environments. Its comprehensive feature set, including a high power supply rating and extensive port density, makes it well-suited for medium to large enterprise networks. By combining scalability with high throughput and PoE+ capabilities, this switch meets the needs of a wide range of applications, from advanced corporate networks to campus environments.
