EX2300-48P-RFB
48-port 10/100/1000BASE-T PoE+, 4 x 1/10GbE, 100W AC Power Consumption, 750W Total PoE Power Budget
Description
The Juniper Networks® EX2300 line of Ethernet switches offers a compact, high-performance solution for supporting today’s converged network access deployments.
Each EX2300 switch includes an ASIC-based Packet Forwarding Engine (PFE) with an integrated CPU to consistently deliver wire-rate forwarding, even with all control plane features enabled. Based on existing, field-proven Juniper Networks technology, the PFE brings the same level of carrier-class performance and reliability to the EX2300 switches that Juniper Networks routers bring to the world’s largest service provider networks.
Select EX2300 models also support the 802.3af Class 3 Power over Ethernet (PoE) and 802.3at PoE+ standards for supporting networked devices such as telephones, video cameras, IEEE 802.11ac WLAN access points, and videophones in converged networks. The PoE-enabled EX2300 switches include a maximum system budget of 750 watts to deliver up to 30 watts to select ports.
Multiple EX2300 models are available, including versions offering multigigabit (up to 2.5 Gbps) PoE+ access ports that can accommodate higher-speed IEEE 802.11ac Wave 2 access points, enabling the switches to support more wireless users.

- Virtual Chassis technology enables up to four interconnected EX2300 switches to form a single logical device
- Flexible 1GbE SFP/10GbE SFP+ uplinks provide high-speed connectivity to aggregation layer switches or other upstream devices
- Up to 48 10/100/1000BASE-T ports are available with or without PoE/PoE+
- Models offering 24 and 48 multigigabit ports support 1GbE/2.5GbE on 8 and 16 ports, respectively
- Energy Efficient Ethernet (EEE) support is provided on 1GbE ports
- Complete Layer 2 and basic Layer 3 switching capabilities are available
- Simplified onboarding and management with Juniper Mist Wired Assurance
