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.
