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.
