Product Description

The Juniper Networks® EX2300 line of Ethernet switches offers a compact, high-

performance solution for supporting today’s converged network access deployments.

Each EX2300 switch includes an ASIC-based Packet Forwarding Engine (PFE) with an

integrated CPU to consistently deliver wire-rate forwarding, even with all control plane

features enabled. Based on existing, field-proven Juniper Networks technology, the PFE

brings the same level of carrier-class performance and reliability to the EX2300 switches

that Juniper Networks routers bring to the world’s largest service provider networks.

Select EX2300 models also support the 802.3af Class 3 Power over Ethernet (PoE) and

802.3at PoE+ standards for supporting networked devices such as telephones, video

cameras, IEEE 802.11ac WLAN access points, and videophones in converged networks. The

PoE-enabled EX2300 switches include a maximum system budget of 740 watts to deliver

up to 30 watts to select ports.

Multiple EX2300 models are available, including versions offering multigigabit (up to 2.5

Gbps) PoE+ access ports that can accommodate higher-speed IEEE 802.11ac Wave 2

access points, enabling the switches to support more wireless users.

Architecture and Key Components

The EX2300 occupies a single rack unit, delivering a compact

solution for crowded wiring closets and access locations where

space and power are at a premium. The EX2300 switch’s

10-inch/12-inch depth and low acoustics also make it ideal for

open oce deployments. For silent operation requirements, please

see the EX2300-C, a compact, fanless version of the EX2300.

Each EX2300 switch supports four fixed front-panel 1GbE/10GbE

uplink ports (six 1/10GbE uplink ports on the 48-port multigigabit

model) with pluggable optics (purchased separately) for high-

speed backbone or link aggregation connections between

wiring closets and upstream aggregation switches. The 1GbE

EX2300 access switch models also feature a front-panel mode

button that offers a simple interface for bringing devices up and

selecting LED modes.

A dedicated rear panel RJ-45 Ethernet port is available for out-

of-band management, while a rear panel USB port can be used

to easily upload the Junos OS and configuration files.

Junos Fusion Enterprise Technology

Juniper Networks Junos Fusion Enterprise technology provides

automated network configuration and simplifies scalability for

medium to large enterprise networks. Using Juniper Networks

EX9200 line of programmable switches as aggregation devices

and EX2300 switches as satellite nodes, Junos Fusion Enterprise

technology can be deployed across a building (or multiple

buildings) to connect large numbers of switches in a fabric that

can be managed as a single device.

EX2300 Satellite Devices

Figure 1: Junos Fusion Enterprise deployment using EX2300

switches as satellite devices

With Junos Fusion technology, enterprises can reduce network

complexity and operational costs by collapsing underlying

network elements into a single logical point of control from

Junos OS-based Juniper routing and switching platforms. It is

designed for customers who need to cost-effectively deploy

numerous switch ports throughout their enterprise campus

network and manage them all from a central device. In addition,

existing EX2300 switches can be easily added to a Junos Fusion

Enterprise deployment with a simple software upgrade, offering

full investment protection.

In Junos Fusion Enterprise deployments, satellite devices do not

require to be individually connected to aggregation devices. Up

to 10 satellite devices can be interconnected via standard 10GbE

interfaces to form a “cluster,” which in turn can be connected to

the aggregation device(s) over a pair of fiber uplinks. Satellite

devices or clusters can also be dual-homed or single-homed to

the aggregation devices.

In Junos Fusion Enterprise deployments, satellite devices forward all

trac to the aggregation device, enabling network administrators

to monitor and manage the entire enterprise campus building from

a single device. Features such as PoE/PoE+, LLDP-MED, and 802.1x

are also supported in Junos Fusion Enterprise architectures to help

meet enterprise campus requirements.

Virtual Chassis Technology

The EX2300 supports Juniper’s unique Virtual Chassis

technology, enabling up to four interconnected EX2300 switches

to be managed as a single logical device, delivering a scalable,

pay-as-you-grow solution for expanding network environments.

While EX2300 switches can be interconnected over any of the

front-panel uplink ports using standard 10GbE SFP+ transceivers

(sold separately), these ports can also be configured as

1GbE/10GbE uplinks to aggregation devices by disabling the

Virtual Chassis technology.

When deployed in a Virtual Chassis configuration, the EX2300

switches elect a primary and a backup switch based on a

set of preconfigured policies or criteria. The primary switch

automatically creates and updates the switching and optional

routing tables on all other Virtual Chassis switch members.

Switches can be added to or removed from the Virtual Chassis

configuration without service disruption.

Data SheetEX2300 Eth ernet Switch

EX2300 Virtual Chassis configurations operate as highly resilient

unified systems, providing simplified management using a single

IP address, single telnet session, single command-line interface

(CLI), automatic version checking, and automatic configuration.

The EX2300 switches are also capable of local switching, so

packets coming into a port destined for another port on the same

switch do not have to traverse the Virtual Chassis, increasing

forwarding capacities.

EX2300 Virtual Chassis configurations implement the

same slot/module/port numbering schema as other Juniper

Networks chassis-based products, providing true chassis-like

operations. By using a consistent operating system and a single

configuration file, all switches in a Virtual Chassis configuration

are treated as a single device, simplifying overall system

maintenance and management.

Multigigabit Switches

IEEE 802.11ac Wave 2 access points require switch ports capable

of handling up to 2.5 Gbps in order to support the growing

number of wireless devices and the amount of traffic they

produce. To address this need, specific multigigabit EX2300

models now offer 1 Gbps and 2.5 Gbps access ports to support

these increased bandwidth requirements over existing Category

5e cabling. These switches run the same Junos image and

support all the same software features as other EX2300 models.

The EX2300 multigigabit switches can interoperate with other

EX Series switches in Junos Fusion Enterprise and Virtual Chassis

deployments*, protecting existing customer investments by

enabling them to add multigigabit support to their existing

Juniper network deployments.

The EX2300 multigigabit switches support PoE+ on all access

ports, provided the power demand is within the PoE budget.

Simplified Management and Operations

Junos Fusion Enterprise technology dramatically simplifies EX2300

management by enabling a large number of the switches to

be managed from a single interface when deployed as satellite

devices. With features such as plug-and-play deployment and

rolling soware upgrades, Junos Fusion Enterprise eliminates the

need to individually manage every access switch in the enterprise

network, leading to lower operational costs and overall lower TCO.

Virtual Chassis technology simplifies network management

for smaller deployments. Up to four interconnected EX2300

switches can be managed as a single device utilizing a single

Junos OS image and a single configuration file, reducing the

overall number of units to monitor and manage. When the Junos

OS is upgraded on the primary switch in an EX2300 Virtual

Chassis configuration, the software is automatically upgraded on

all other member switches at the same time.

The EX2300 includes port profiles that allow network

administrators to automatically configure ports with security,

QoS, and other parameters based on the type of device

connected to the port. Six preconfigured profiles are available,

including default, desktop, desktop plus IP phone, WLAN access

point, routed uplink, and Layer 2 uplink. Users can select from

the existing profiles or create their own and apply them through

the command-line interface (CLI), J-Web Software interface, or

management system.
