EX2300 Switches Hardware Overview

Juniper Networks EX Series Ethernet Switches provide scalable connectivity for the enterprise market, including branch offices, campus locations, and data centers. The Juniper Networks EX2300 Ethernet Switches run the Juniper Networks Junos operating system (Junos OS), which provides Layer 2 and Layer 3 switching, routing, and security services.

EX2300 switches provide connectivity for low-density environments.

EX2300 Switches First View

EX2300 switches are available in models with 12 or 24, or 48 built-in network ports that supportRJ-45cableconnectors.Thecompact,fanlessEX2300-Cswitcheshave12RJ-45 network ports.

EX2300-C and EX2300 Switches Hardware Guide

EX2300 switches provide:

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

•12(inEX2300-Cswitches),24,or48built-inGigabitEthernetRJ-45networkportswith 10/100/1000 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 that support SFP and SFP+ transceivers. EX2300 switches except the EX2300-C switch model and the have four 10-Gigabit Ethernet uplink ports that 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.

NOTE: You cannot form a Virtual Chassis by using SFP transceivers.

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 Switch as a Virtual Chassis Port (CLI Procedure).

For information about the supported optical and copper interfaces, see “Pluggable

Transceivers Supported on EX2300 Switches” on page 75.

Console Ports

EX2300switcheshavetwoconsoleports—anRJ-45consoleportandaMini-USBType-B 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” on page 105, “Mounting an EX2300-C Switch Under a Desk or Other Level Surface by Using Screws” on page 107, and “Mounting an EX2300-C Switch on or Under a Surface Made of Ferrous Material” on page 126.

Chapter 1: System Overview

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” on page 105, “Mounting an EX2300-C Switch Under a Desk or Other Level Surface by Using Screws” on page 107, and “Mounting an EX2300-C Switch on or Under a Surface Made of Ferrous Material” on page 126.

Power over Ethernet (PoE) Ports

EX2300switchesareavailablewithorwithoutPoE/PoE+capability.Modelsthatsupport 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.

NOTE: IEEE 802.3at class 4 powered devices require category 5 or higher

Ethernet cables.

Front Panel of an EX2300 Switch

The front panel of an EX2300-C switch consists of the following components:

•RJ-45 network ports—depending on the switch model, either of:

•12 10/100/1000 BASE-T Gigabit Ethernet ports with PoE/PoE+ capability in EX2300-C-12P

•12 10/100/1000 BASE-T Gigabit Ethernet ports without PoE capability in EX2300-C-12T

•One USB port

•One management Ethernet port

•Three chassis status LEDs

•Four port status mode LEDs in models with PoE capability and three port status mode LEDs in models without PoE capability

•One Factory Reset/Mode button

•One mini-USB console port

•One RJ-45 console port

EX2300-C and EX2300 Switches Hardware Guide

•Two built-in 10-Gigabit Ethernet uplink ports. You can use the uplink ports to forward network traffic or configure them as VCPs to interconnect EX2300 switches into a Virtual Chassis.

•One electrostatic discharge (ESD) point
