Product Review

The Juniper EX2300-48P offers a high PoE power budget of 750 W and supports up to 52 GbE ports, including 4 1/10GbE SFP/SFP+ uplinks, making it suitable for dense deployments. However, its maximum system power consumption of 100 W (without PoE) and 51.4 dB acoustic noise level might be concerns for energy-sensitive and noise-sensitive environments. Additionally, the capability to interconnect up to four switches with an 80 Gbps Virtual Chassis configuration enhances scalability and simplifies management for growing networks.


The Juniper EX2300-48P is a network switch designed to cater to the demands of modern enterprise networks. It features 48 10/100/1000BASE-T PoE+ ports and four 1/10GbE SFP/SFP+ uplink ports, offering a versatile set of connectivity options. This switch is engineered to support a wide array of networked devices while ensuring efficient power distribution with a total Power over Ethernet (PoE) power budget of 750 W. Despite its extensive capabilities, the system maintains a relatively low power consumption, drawing a maximum of 100 W AC without PoE devices connected. Dimensionally, the EX2300-48P is built for adaptability. It measures 17.4 inches in width for desktop installations and slightly wider at 17.5 inches with rack-mount brackets. The height is standardized at 1.75 inches, fitting a 1U rack space, and it extends 12.2 inches in depth. Weighing in at 11.07 lb (5.02 kg), it strikes a balance between durability and ease of installation. The airflow is rated at 25 cubic feet per minute (cfm), indicating a designed efficiency in cooling. Connectivity is a strong suit of the EX2300-48P, with a GbE port density per system tallying up to 52 ports. This includes the 48 host ports and the additional four-port SFP/SFP+ uplinks. The switch boasts impressive packet-switching capacities of 88 Gbps unidirectional and 176 Gbps bidirectional. Furthermore, it supports a maximum of 16,000 MAC addresses in hardware, accommodates jumbo frames up to 9216 bytes, and can handle a maximum of 1,500 Neighbor Discovery (ND) and ARP entries each.
  • 80 Gbps Virtual Chassis interconnect to link up to four switches as a single logical device.
  • Operating temperatures range from 32°F to 113°F, with storage temperatures extending from -40°F to 158°F.
  • The acoustic noise level is measured at 51.4 dB, optimizing for a quieter operating environment.
The EX2300-48P is designed to operate efficiently across a broad range of conditions, with an operational altitude ceiling of 10,000 ft and a non-operating altitude limit of 16,000 ft. These features ensure reliability and performance even in challenging physical environments. In summary, the Juniper EX2300-48P integrates high port density, flexible uplink connectivity, and efficient power management into a compact, 1U form factor. It is engineered to support the dynamic needs of enterprise networks, from advanced data centers to high-demand office environments. With its comprehensive set of features and specifications, the EX2300-48P stands out as a scalable, efficient, and reliable choice for modern network infrastructures.
