Product Overview

The Juniper Networks EX4300

line of Ethernet switches

delivers the performance

and scale required for both

campus and data center Gigabit

Ethernet (GbE) access switch

deployments. Combined with

Juniper’s market leading Virtual

Chassis technology, the EX4300

scales up to 10 members,

delivering the high availability

and plug-and-play scale that

businesses demand. Combining

compact, pay-as-you-grow

economics and low power and

cooling with the performance,

availability, and port densities

of chassis-based platforms, the

EX4300 with Virtual Chassis

technology enables businesses

to deploy with speed and agility

to increase revenue and improve

productivity.

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 form-

factor 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, hot-

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

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

based 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.

Chassis-Like Features in an Expandable Form Factor

The fixed-configuration EX4300 switches include a number of high availability features

typically associated with chassis-based solutions, including the following:

• Hot-swappable fans

• Modular Juniper Networks Junos

operating system (consistent with chassis systems)

• Dual Routing Engines with graceful Routing Engine switchover (GRES) in a Virtual

Chassis conﬁguration

• Single management interface

• Easy, centralized soware upgrades

• Scalability from 24 to 480 10/100/1000BASE-T ports, with up to 40 10GbE uplinks and

40 40GbE uplinks

EX4300 Ethernet Switch Data Sheet Virtual Chassis Deployments in the Data Center Collapsed Core/Aggregation When deployed in a Virtual Chassis configuration in the data center, all EX4300 switches are monitored and managed as a single device, enabling enterprises to separate physical topology from logical groupings of endpoints and allowing more efficient resource utilization. Highly resilient topologies can also be created using the 40GbE DAC cables.
