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 support RJ-45 cableconnectors.The compact, fanlessEX2300-C switches have12 RJ-45 network ports.
3Copyright © 2017, Juniper Networks, Inc.
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 (in EX2300-C switches), 24, or 48built-in Gigabit Ethernet RJ-45 network ports with 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 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.
Console Ports
Cable Guard
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 73.
EX2300 switches havetwo console ports—an RJ-45 consoleport and a Mini-USB Type-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. The switch activates only one console port at a time—either the RJ-45 console port or the Mini USB Type-B console port. By default, the RJ-45 port is the active console port and the Mini-USB Type-B port is the passive console port. You can change the default setting of a console port by using the port-type command. See Configuring the Console Port Type (CLI Procedure).
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 129, “Mounting an EX2300-C Switch Under a Desk or Other Level Surface by Using
Copyright © 2017, Juniper Networks, Inc.4
Screws” on page 131, and “Mounting an EX2300-C Switch on or Under a Surface Made of Ferrous Material” on page 149.
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 129, “Mounting an EX2300-C Switch Under a Desk or Other Level Surface by Using Screws” on page 131, and “Mounting an EX2300-C Switch on or Under a Surface Made of Ferrous Material” on page 149.
Power over Ethernet (PoE) Ports
EX2300 switches areavailablewith 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.
Chapter 1: System Overview
NOTE: IEEE 802.3at class 4 powered devices require category 5 or higher
Ethernet cables.
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.
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
