Comprehensive Product Overview

The Juniper EX2300-48T is a fixed-configuration, 1U rackmount Ethernet switch built for entry-level enterprise access layers, branch offices, remote sites, and small-to-medium campus networks. As part of Juniper’s EX2300 series, it balances high port density, performance, and affordability for converged data, voice, and video traffic.

Equipped with 48x 10/100/1000BASE-T copper ports for end-device connectivity (PCs, printers, IP cameras, wireless APs) and 4x SFP/SFP+ slots for flexible 1GbE or 10GbE fiber uplinks to aggregation/core switches. Powered by Juniper’s ASIC-based Packet Forwarding Engine (PFE) and a 1.25GHz ARM CPU, it delivers 176 Gbps switching capacity and 130 Mpps wire-rate Layer 2 throughput without performance degradation.

Running on Junos OS, the EX2300-48T provides consistent, carrier-grade reliability across Juniper’s product portfolio, simplifying management and reducing operational complexity. It supports Virtual Chassis (up to 4 switches as one logical device) and Junos Fusion Enterprise (satellite mode), enabling scalable, unified network management for growing environments. With Energy Efficient Ethernet (EEE) and robust security features, it meets modern enterprise demands for efficiency, security, and scalability.
