Juniper Networks EX4200 Switches

High-Performance Carrier-Class Ethernet Switches

The EX4200 line of Ethernet switches, designed for access and aggregation deployments, combines the best features of modular, chassis-based systems into a compact, efficient form factor suitable for enterprise networks.

Available Models & Configurations

• EX4200-24T – 24-port 10/100/1000BASE-T (non-PoE)
• EX4200-24P – 24-port 10/100/1000BASE-T with full PoE+ (all 24 ports)
• EX4200-24F – 24-port 100/1000BASE-X SFP (fiber)
• EX4200-48T – 48-port 10/100/1000BASE-T (non-PoE)
• EX4200-48P – 48-port 10/100/1000BASE-T with partial PoE+ (8 ports)
• EX4200-48PX – 48-port 10/100/1000BASE-T with full PoE+ (all 48 ports)

Uplink Expansion Modules:

• EX-UM-4SFP (4-port 1GbE SFP)
• EX-UM-2XFP (2-port 10GbE XFP)

EX4200 switches offer flexible 10/100/1000BASE-T and fiber (SFP) configurations, with optional PoE support for powering devices like IP phones, cameras, and wireless access points.

Virtual Chassis Technology

The standout feature of the EX4200 series is Juniper's Virtual Chassis technology, which allows up to 10 switches to interconnect over a 128 Gbps backplane, forming a single logical device. This supports:

• Up to 480 users
• Up to 20x 10GbE uplinks
• Simplified management (single Junos OS & config file)

When deployed in a Virtual Chassis, EX4200 switches can span multiple locations (e.g., different floors or buildings) while operating as one unified system. This enables incremental scaling—start with a single switch and expand as needed, avoiding the cost and complexity of traditional chassis-based solutions.

Reliability & Junos OS

• Hot-swappable power supplies & field-replaceable fan tray for high availability
• Runs Junos OS, ensuring consistent features across Juniper's routing, switching, and security platforms

Ideal for enterprises needing scalable, high-density access-layer switching with carrier-class reliability.
