Juniper Networks EX 4200 Switch, 24-port 10/100/1000BaseT PoE-plus + 930W AC PS, includes 50cm VC cable The Juniper Networks EX 4200 series 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

Juniper Networks EX 4200 Switch, 24-port 10/100/1000BaseT PoE-plus + 930W AC PS, includes 50cm VC cable The Juniper Networks EX 4200 series 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 EX 4200 series switches satisfy 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 Virtual Chassis technology allows up to 10 EX 4200 series 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 EX 4200 series 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 EX 4200 series switch models offer Class 3 power over Ethernet (PoE), delivering 15.4 watts on the first eight ports to support IP-enabled 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.Each EX 4200 series switch includes an integrated application-specific integrated circuit (ASIC)-based packet-forwarding engine, the EX-PFE, while an integrated Route Engine (RE) delivers all control plane functionality. Based on field-proven Juniper technology, the Route Engine brings the same level of carrier-class performance and reliability to the EX 4200 series switches that Juniper routers bring to the world's largest service provider networks.The EX 4200 series switches also leverage the same modular JUNOS software as Juniper router products, ensuring a consistent implementation and operation of each control plane feature across an entire Juniper infrastructure.
