The Juniper Networks® EX4200 line of Ethernet switches with Virtual Chassis technology combine the high availability (HA) and carrier-class reliability of modular systems with the economics and flexibility of stackable platforms, delivering a high-performance, scalable solution for data center, campus and branch office environments.
Offering a full suite of Layer 2 and Layer 3 switching capabilities as part of the base software, the EX4200 satisfies a variety of high-performance applications, including branch, campus and data center access deployments as well as Gigabit Ethernet (GbE) aggregation deployments. A single 24-port or 48-port switch can be deployed initially; as requirements grow, Juniper Networks Virtual Chassis technology allows up to 10 EX4200 switches to be interconnected over a 128 gigabit-per-second (Gbps) backplane and managed as a single device, delivering a scalable, pay-as-you-grow solution for expanding network environments. Flexible Gigabit Ethernet (GbE) and 10-Gigabit Ethernet (10GbE) uplink options enable high-speed connectivity to aggregation- or core-layer switches which connect multiple floors or buildings.
All EX4200 switches include HA features such as redundant, hot-swappable internal power supplies and field-replaceable, multi-blower fan trays to ensure maximum uptime. In addition, the base EX4200 partial PoE switch models offer Class 3 Power over Ethernet (PoE), delivering up to 18.6 watts on the first eight ports to support networked devices such as telephones, video cameras and wireless LAN (WLAN) access points for low-density converged networks. Full PoE options delivering up to 18.6 watts on all 24 or 48 ports are also available, making them ideal for high-density IP telephony deployments. Furthermore, PoE+ models deliver up to 30 watts of standards-based 802.3at PoE+ on 24 or 48 ports making them ideal for all PoE applications including campus deployments with 802.11n wireless access points.
Juniper Networks Virtual Chassis Technology: Chassis-like Switch Features in a Stackable Form Factor
- Redundant, internal hot-swappable power supplies
- Hot-swappable fan tray with redundant blowers
- Consistent modular Juniper Networks Junos® operating
- system control plane feature implementation
- Dual Route Engines with Graceful Routing Engine
- Switchover (GRES)
- Single management interface
- Easy, centralized software upgrades
- Scales from 24 to 480 ports with up to 20 10GbE uplinks
Each EX4200 switch includes an integrated application-specific integrated circuit (ASIC)-based Packet Forwarding Engine, the EX-PFE, while an integrated Routing Engine (RE) delivers all control plane functionality. Based on field-proven Juniper Networks technology, the Route Engine brings the same level of carrier-class performance and reliability to the EX4200 line of Ethernet switches that Juniper Networks routers bring to the world’s largest service provider networks.
The EX4200 also leverages the same modular Juniper Networks Junos OS as Juniper Networks router products, ensuring a consistent implementation and operation of each control plane feature across an entire Juniper Networks infrastructure.
