EX2300 System Overview

Benefits of the EX2300 Switch

Economical—EX2300 switches offer an economical, entry-level, standalone solution for access-layer deployments in branch and remote offices, as well as enterprise campus networks. 1 Gbps and 2.5 Gbps access port options provide high speed options, especially when connecting to 802.11ac Wave 2 access points.

High flexibility and class leading features—EX2300 switches provide the highest levels of flexibility and features in its class to support data, voice, and video environments, delivering a reliable platform for unifying enterprise communications.

Support for Juniper Networks Junos Fusion Enterprise—EX2300 switches can act as a satellite device to support a Juniper Networks Junos Fusion Enterprise deployment, which can combine several wiring closets into one logical management platform. In smaller networks, you can connect up to four EX2300 switches in a Virtual Chassis configuration, allowing them to be managed as a single switch.

EX2300 Switches First View

EX2300 switches are available in models with 12 or 24, or 48 built-in network ports that support RJ-45 cable connectors. The compact, fanless EX2300-C switches have 12 RJ-45 network ports.

EX2300 switches provide:

• Up to six 10-Gigabit Ethernet uplink ports that support small form-factor pluggable plus (SFP+) transceivers and small form-factor pluggable (SFP) transceivers.

• 12 (in EX2300-C switches), 16, 24, 32, or 48 built-in Gigabit Ethernet RJ-45 network ports with 10/100/1000 BASE-T connectors.

• Eight or 16 built-in Gigabit Ethernet RJ-45 network ports with 100/1000/2500 BASE-T connectors.

• Virtual Chassis capability—You can connect up to four EX2300 switches (including EX2300-C switches) to form one unit that you manage as a single chassis, called a Virtual Chassis.

• Power over Ethernet (PoE) or Power over Ethernet Plus (PoE+) on all RJ-45 network ports (in PoE-capable models).

Uplink Ports

EX2300-C switches have two 10-Gigabit Ethernet uplink ports. EX2300 switches except the EX2300-C switch model and the EX2300-48MP switch model have four 10-Gigabit Ethernet uplink ports. The EX2300-48MP switch model has six 10-Gigabit Ethernet uplink ports. These uplink ports support SFP and SFP+ transceivers. You can use these uplink ports as network ports or configure these ports as Virtual Chassis ports (VCPs) and use them to connect up to four switches by using SFP+ transceivers to form a Virtual Chassis.

For forming a Virtual Chassis, you must explicitly configure an uplink port on each of the switches to be connected as a VCP. See Setting an Uplink Port on an EX Series or QFX Series Switch as a Virtual Chassis Port.

For information about the supported optical and copper interfaces, see Pluggable Transceivers Supported on EX2300 Switches.

Console Ports

EX2300 switches except the EX2300-24MP and EX2300-48MP switch models have two console ports—an RJ-45 console port and a Mini-USB Type-B console port. EX2300-24MP and EX2300-48MP switch models have an RJ-45 console port. The RJ-45 port accepts a cable that has an RJ-45 connector and the Mini-USB Type-B port accepts a Mini-B plug (5-pin) connector to connect the switch to a console management device.

Cable Guard

On an EX2300-C switch, you can install a cable guard to secure the cables connected to the switch. The cable guard has slots in the front of it through which you can pass all the cables to prevent them from being accidently unplugged or removed after they are connected. See Mounting an EX2300 Switch on a Desk or Other Level Surface, Mounting an EX2300-C Switch Under a Desk or Other Level Surface by Using Screws, and Mounting an EX2300-C Switch on or Under a Surface Made of Ferrous Material.

Security Slot

An EX2300-C switch has a security slot on the right panel of the chassis. You can use the security slot to lock and secure the chassis in the installation site with a standard cable lock. See Mounting an EX2300 Switch on a Desk or Other Level Surface, Mounting an EX2300-C Switch Under a Desk or Other Level Surface by Using Screws, and Mounting an EX2300-C Switch on or Under a Surface Made of Ferrous Material.

Power over Ethernet (PoE) Ports

EX2300 switches are available with or without PoE/PoE+ capability. Models that support PoE/PoE+ provide that support on all RJ-45 network ports. PoE ports provide electrical current to devices—such as IP phones, wireless access points, and security cameras—through network cables, thus eliminating the need for separate power cords for those devices. Uplink ports do not support PoE.

The remainder of this topic uses the term PoE to refer to both PoE and PoE+ unless there is a need to distinguish between the two.
