High-performance businesses demand high-performance networking solutions. These solutions include a new class of secure, scalable and always-on enterprise switch that advances the economics of networking by enabling businesses to deploy innovative new technologies that increase revenue and improve productivity. The Juniper Networks EX4200 line of Ethernet switches with Virtual Chassis technology combine the compact, pay-as-you-grow economics and low power and cooling requirements of stackable switches with the performance, availability, operational ease and port densities of chassis-based platforms to meet the demands of today’s high-performance enterprises.

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 (10 GbE) 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 switch models offer Class 3 Power over Ethernet (PoE), delivering 15.4 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 15.4 watts on all 24 or 48 ports are also available, making them ideal for high-density IP telephony deployments.
