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 cable connectors.Thecompact,fanlessEX2300-C switches have 12 RJ-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 (in EX2300-C switches), 24, or 48 built-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 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.
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 75.
EX2300 switches have twoconsole ports—an RJ-45 console port 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.
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.
Copyright © 2017, Juniper Networks, Inc.4
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
EX2300 switches are availablewithor 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.
NOTE: IEEE 802.3at class 4 powered devices require category 5 or higher
Ethernet cables.
Chapter 1: System Overview
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
