Product overview

The Juniper EX2300-48MP is a compact, high-density access layer switch designed for enterprise branch offices, remote locations, and small network environments where space and power efficiency are critical. It features 48 multi-gigabit Ethernet ports (supporting 10/100/1000/2.5G/5G) with comprehensive PoE+ support delivering 750W total power budget (30W per port), plus six 10G SFP+ uplink ports for high-speed interconnection. With 264Gbps bidirectional switching capacity and 130 Mpps wire-speed forwarding, the EX2300-48MP provides non-blocking performance for access layer deployments. The switch includes dual hot-swappable AC power supplies, 8GB Flash storage, 2GB DRAM, and a 1.25GHz ARM CPU running Junos OS. It supports comprehensive Layer 2 and basic Layer 3 switching with OSPF, BGP, RIP, and PIM routing protocols. Advanced security features include 802.1X authentication, MACsec encryption, DHCP snooping, and dynamic ARP inspection. The 1U form factor (17.4" × 1.75" × 14.5") enables dense rack deployment while maintaining low power consumption (90W non-PoE, 750W with full PoE load). Virtual Chassis capability allows linking up to four switches as a single logical device with 80Gbps interconnect bandwidth.

Frequently asked questions

What is the switching capacity and forwarding performance of the EX2300-48MP?

The EX2300-48MP delivers 264Gbps bidirectional switching capacity with 132Gbps unidirectional throughput and 130 Mpps wire-speed forwarding rate. This non-blocking architecture ensures simultaneous full-speed communication across all 48 ports plus six 10G uplinks, eliminating bottlenecks in access layer deployments.

How much PoE power does the EX2300-48MP provide and what devices can it support?

The switch provides 750W total PoE+ budget (IEEE 802.3at) with up to 30W per port. This enables simultaneous operation of 48 powered devices such as IP phones (3-6W), IP cameras (5-15W), and wireless access points (10-20W), making it ideal for high-density unified communications and surveillance deployments.

What uplink options does the EX2300-48MP offer for core connectivity?

Six 10G SFP+ uplink ports provide high-speed aggregation to core switches or data center infrastructure. These support 1000BASE-SX/LX/LH single-mode and multimode fiber optics (sold separately), enabling flexible long-distance interconnection with 80Gbps Virtual Chassis bandwidth for multi-switch clustering.

What Layer 3 routing protocols are supported on the EX2300-48MP?

The switch supports OSPF, BGP, RIP, and PIM routing protocols with 512 IPv4 prefix routes, 4,096 IPv4 host routes, 512 IPv6 prefix routes, and 2,048 IPv6 host routes. This enables basic Layer 3 switching for small branch networks requiring dynamic routing without dedicated router hardware.

Can multiple EX2300-48MP switches be clustered together for redundancy?

Yes, up to four EX2300-48MP switches can be linked via Virtual Chassis with 80Gbps interconnect bandwidth, creating a single logical device. This simplifies management through unified configuration and enables non-disruptive software upgrades while providing redundancy for growing branch office networks.

What security features does the EX2300-48MP include?

Security features include 802.1X port-based authentication, MACsec encryption, DHCP snooping, dynamic ARP inspection, and support for 4,093 VLANs with 2,044 active VLANs. These capabilities protect against unauthorized access, ARP spoofing, and DHCP attacks in multi-tenant or high-security branch environments.

What is the power consumption and thermal profile of the EX2300-48MP?

Base power consumption is 90W without PoE; maximum consumption reaches 750W with full PoE load. Cooling operates at 45.8 dB at full PoE load. Operating temperature range is 0–45°C (32–113°F). The compact 1U form factor (17.4" × 1.75" × 14.5") and low thermal output make it suitable for space-constrained branch office environments.
