he Juniper EX2300-48P is a high-density, high-power 48-port Gigabit Ethernet PoE+ switch with 4x 1/10GbE SFP/SFP+ uplink slots, designed for enterprise campus access, large branch offices, and PoE-heavy environments (wireless APs, IP cameras, VoIP phones). Delivering a 740W total PoE budget, wire-speed performance, and Juniper’s reliable Junos OS, it provides cost-effective, scalable, and secure connectivity for modern converged networks.
Comprehensive Product Overview
The Juniper EX2300-48P is a fixed-configuration, 1U rackmount Ethernet switch purpose-built for entry-level enterprise access layers, mid-to-large branch offices, retail chains, and small-to-medium campus networks requiring high Power over Ethernet (PoE+) capacity. As part of Juniper’s EX2300 series, it balances industry-leading PoE power budget, port density, performance, and affordability for converged data, voice, video, and wireless traffic.
Equipped with 48x 10/100/1000BASE-T PoE+ ports (IEEE 802.3af/at, up to 30W per port) for powering and connecting end devices (wireless 802.11ac/ax APs, high-resolution IP security cameras, VoIP phones, PoE sensors, and building automation devices) and 4x SFP/SFP+ slots for flexible 1GbE (SFP) or 10GbE (SFP+) 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 EX2300-48P 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), robust enterprise security, and cloud management readiness via Juniper Mist Wired Assurance, it meets modern enterprise demands for efficiency, security, and scalability.
