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 satisfies

a variety of high-performance applications, including branch, campus, and data center

access deployments as well as Gigabit Ethernet (GbE) access 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 EX4300 switches to be interconnected and

managed as a single device, delivering a scalable, pay-as-you-grow solution for expanding

network environments. 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. Flexible 1GbE and 10GbE uplink options are 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 a Stackable Form Factor

The fixed-configuration EX4300 switches include a number of HA features typically

associated with chassis-based solutions, including the following:

• Hot-swappable fans

• Consistent modular Juniper Networks Junos® operating system control plane feature

implementation

• Dual Routing Engines with graceful Routing Engine switchover (GRES)

• 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

• Limited lifetime hardware warranty

Each EX4300 switch includes an integrated application-specific integrated circuit (ASIC)-based Packet Forwarding Engine, the EXPFE, while an integrated Routing Engine (RE) delivers all control plane functionality. The EX4300 also leverages the same modular Junos OS as other Juniper Networks switches, routers, and security devices, ensuring a consistent implementation and operation of control plane features across the Juniper Networks infrastructure.

• Redundant power supplies: The EX4300 line of Ethernet switches supports internal redundant, load-sharing, hot-swappable, and field-replaceable AC and DC power supplies to maintain uninterrupted operations. Thanks to its compact footprint, the EX4300 requires significantly less power than chassis-based switches delivering equivalent port densities. • Hot-swappable fans: The EX4300 includes hot-swappable fans, providing sufficient cooling even if one of the blowers were to fail.

Simplified Management and Operations When employing Virtual Chassis technology, the EX4300 dramatically simplifies network management. Up to 10 interconnected EX4300 switches can be managed as a single device. Each Virtual Chassis group utilizes a single Junos OS image file and a single configuration file, reducing the overall number of units to monitor and manage.
