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 office 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 highspeed 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.

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 traffic 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.

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 software 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.
