EX4200 Ethernet SwitchEs With Virtual Chassis Technology Product Overview 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-yougrow 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 highperformance enterprises. Product Description 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 lowdensity 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.

Carrier-Class Operating System The EX4200 runs on Junos OS, the same operating system software used by Juniper Networks routers to power the world’s largest and most complex networks. By utilizing a common operating system, Juniper delivers a consistent implementation and operation of control-plane features across all products. To maintain...

The EX4200 also provides a full complement of port security features including DHCP (Dynamic Host Configuration Protocol) snooping, DAI (dynamic ARP inspection) and MAC limiting (per port and per VLAN) to defend against internal and external spoofing, man-in-the-middle and denial-of-service (DoS) attacks. MACsec on the EX4200 A MACsec software license enables the EX4200 to provide near line-rate hardware-based encryption of user traffic on a dualspeed 2x10GbE or 4x1GbE SFP+ MACsec uplink module. Defined by IEEE 802.1AE, MACsec provides secure, encrypted communication at the link layer that is...

Limited Lifetime Warranty The EX4200 includes a limited lifetime hardware warranty that provides return-to-factory switch replacement for as long as the original purchaser owns the product. The warranty includes lifetime software updates, advanced shipping of spares within one business day, and 24x7 JTAC support for 90 days after the purchase date. Power supplies and fan trays are covered for a period of five years. For complete details please visit www.juniper. net/support/warranty.
