Product Description

The Juniper Networks® EX4300 line of Ethernet switches with Virtual Chassis technology

combines the 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, the EX4300 enables a

variety of deployments, including campus, branch and data center access. A single 24-

port or 48-port EX4300 switch can be deployed initially. As requirements grow, Juniper

Networks Virtual Chassis technology allows up to 10 EX4300 switches to be seamlessly

interconnected and managed as a single device, delivering a scalable, pay-as-you-grow

solution for expanding network environments. A pair of 32-port EX4300 fiber switches

can also be deployed as a consolidated aggregation or small core switch. Additionally, the

EX4300 integrates with QFX3500, QFX3600 and QFX5100 10GbE and 40GbE data center

access switches in a single stack or a Virtual Chassis configuration, enabling non-disruptive

10GbE server upgrades and simplified management of a mixed access environment.

The EX4300 switches can be interconnected over multiple 40GbE quad small formfactor

pluggable plus (QSFP+) transceiver ports to form a 320 gigabit per second (Gbps)

backplane. A flexible uplink module that supports both 1GbE and 10GbE options is also

available, enabling high-speed connectivity to aggregation- or core-layer switches which

connect multiple floors or buildings.

All EX4300 switches include high availability (HA) features such as redundant, hotswappable

internal power supplies and field-replaceable fans to ensure maximum uptime.

In addition, Power over Ethernet (PoE)-enabled EX4300 switch models offer standardsbased

802.3at PoE+ for delivering up to 30 watts on all ports for supporting high-density IP

telephony and 802.11n wireless access point deployments.
