Product Description


Overview
The Networks EX2300 Ethernet Switch offers an economical, entry-level, standalone solution for accesslayer deployments in branch and remote offices, as well as enterprise campus networks. To simplify network operations, the EX2300 is hardware-ready to act as a satellite device to support a Networks Junos Fusion Enterprise deployment, which can combine several wiring closets into one logical management platform. For smaller networks, up to four EX2300 switches can be interconnected in a Virtual Chassis configuration, allowing them to be managed as a single switch.

The Networks EX2300 line of Ethernet switches offers a compact, highperformance 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 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.
The EX2300 fixed-configuration Ethernet switches provide exceptional value to enterprise customers by supporting the following keytechnologies:
* Networks Junos Fusion Enterprise allows more than 100 EX2300 switches to be configured as satellite devices that connect to EX9200 core aggregation devices.
* Virtual Chassis technology enables up to four interconnected EX2300 switches to form a single logical device.
* Flexible 4x1GbE SFP/10GbE SFP+ uplinks provide high-speed connectivity to aggregation layer switches or other upstream devices.
* Up to 48 10/100/1000BASE-T ports are available with or without PoE/PoE+.
* Energy Efficient Ethernet (EEE) support is provided on 1GbE ports.
* Complete Layer 2 and basic Layer 3 switching capabilities are available.
* Simplified management uses Juniper Networks Junos Space Network Director and J-Web GUI.

Additional features include:
* PoE-enabled EX2300 switches can simultaneously deliver up to 15.4 watts of standards-based 802.3af Class 3 PoE to a maximum of 48 ports or 30 watts of standards-based 802.3at PoE+ to a maximum of 24 ports, based on a total system budget of 740 watts.
* Uplink ports can be configured as Virtual Chassis interfaces and connected via standard 10GbE optics interfaces (optional license required).
* Fixed power supply and uplink ports ensure operational simplicity.
* Low power consumption, low acoustic fans, and a small 10-inch deep footprint enable flexible, environmentally friendly
deployment.
* Support for L2 protocols as well as L3 protocols like RIP and static routing are included in the base license.
* An optional enhanced license is available for supporting additional L3 protocols such as OSPF, Internet Group Management Protocol (IGMP v1/v2/v3), Protocol Independent Multicast (PIM), Bidirectional Forwarding Detection (BFD), and Virtual Router Redundancy Protocol (VRRP).
* Support is available for IPv6 management, including neighbor discovery, telnet, SSH, DNS, system log, and NTP.
* A single release train for Juniper Networks Junos operating system is supported to ensure a consistent control plane feature implementation.
* Modular Junos OS prevents a switch reboot if a single protocol feature fails.
* The device integrates with Juniper Networks Unified Access Control to provide per-user access control and policing.
* Built-in Web interface (Juniper Networks J-Web Software) is provided.
* RJ-45 serial console port is available.
* USB mini console port is included.
* Out-of-band Ethernet management port is provided.
* Reduction of Hazardous Waste (RoHS) is certified.
