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 (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.
