EX2200 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
switches run the Juniper Networks Junos operating system (Junos OS), which provides
Layer 2 and Layer 3 switching, routing, and security services. The same Junos OS code
base that runs on EX Series switches also runs on all Juniper Networks M Series, MX
Series, and T Series routers and SRX Series Services Gateways.
Juniper Networks EX2200 Ethernet Switches provide connectivity for low-density
environments.

EX2200 Switches First View
EX2200 switches are available in models with 12 , 24, or 48 built-in network ports. The
compact, fanless model, EX2200-C switches have 12 network ports.

EX2200 and EX2200-C Switches Hardware Guide
EX2200 switches provide:
•
Up to four uplink ports
•
12 (compact, fanless model), 24, or 48 built-in networkports with 10/100/1000BASE-T
Gigabit Ethernet connectors
•
Virtual Chassis capability—Starting with Junos OS Release 12.2, you can connect up to
four EX2200 switches (including EX2200-C switches) together to form one unit that
you manage as a single chassis, called a Virtual Chassis. For information about
understanding and configuring Virtual Chassis, see Virtual Chassis Feature Guide for
EX2200, EX3300, EX4200, EX4500 and EX4550 Switches.
•
Power over Ethernet (PoE or PoE+) on all network ports (in PoE-capable models)
Uplink Ports
Each EX2200 switch except the EX2200-C switch model has four uplink ports that
support 1-gigabit small form-factor pluggable (SFP) transceivers for use with fiber
connections and copper connections.
Console Port
Each EX2200-C switch has two dual-purpose uplink ports. Each dual uplink port consists
of an RJ-45 port (in which you can connect a copper Ethernet cable) and an SFP port
(into which you can plug a transceiver). Only one of the ports can be active at a time. By
default, if you connect a copper Ethernet cable to the RJ-45 port, this port becomes the
active port provided that there is no connection made on the other port. If you plug a
transceiver into the SFP port, this port becomes the active port whether or not a copper
Ethernet cable is connected to the other port. You can change this default behavior by
explicitly configuring a media type—copper or fiber—for the dual-purpose port by using
the media-type command. For more information, see Configuring the Media Type on
Dual-Purpose Uplink Ports (CLI Procedure).
You can use an SFP uplink port connection between EX2200 switches to interconnect
the switches into an EX2200 Virtual Chassis. For this, you must explicitly configure an
SFP port each on 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 EX2200 Switches” on page 67.
Each EX2200 switch exceptthe EX2200-C switch model has an RJ-45console port that
accepts a cable with RJ-45 connector.
The EX2200-C switch has two console ports: an RJ-45 port and a Mini-USB Type-B port.
The RJ-45 console port accepts a cable with an RJ-45 connector and the Mini-USB
Type-B console port accepts a Mini-B plug (5-pin) connector to connect to the 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).
Copyright © 2017, Juniper Networks, Inc.4
Cable Guard
On an EX2200-C switch model, 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 EX2200 Switch on a Desk or Other Level
Surface” on page 92.
Security Slots
Each EX2200-C switch model has security slots on the left and right panels of the chassis.
Use the security slots tolock and secure the chassis in the installationsite with a standard
cable lock . See “Mounting an EX2200 Switch on a Desk or Other Level Surface” on
page 92.
Power over Ethernet (PoE) Ports
EX2200 switches are available in models with or without PoE/PoE+ capability. Models
that support PoE/PoE+ provide that support on all 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.
Chapter 1: System Overview
EX2200 switches with DC power supply do not provide PoE.
NOTE: Starting with Junos OS Release 12.2R1, PoE commands are enabled
on all non-PoE-capable EX2200 switch models. The PoE commands do not
provide any meaningful information on standalone non-PoE-capable switch
models. However, in an EX2200 Virtual Chassis, you can execute PoE
commands from a non-PoE-capable switch that is the master, to configure
PoE on PoE-capable Virtual Chassis members.
PoE-capable EX2200 switches running Junos OS Release 10.3 or later support powered
devices that comply with IEEE 802.3af (PoE) and IEEE 802.3at (PoE+).
NOTE: IEEE 802.3at class 4 powered devices require category 5 or higher
Ethernet cables.
EX2200 switches running Junos OS Release 10.2 or earlier support powered devices that
comply with IEEE 802.3af (PoE).
The remainder of this topicuses the term PoE to refer to both PoE and PoE+ unless there
is a need to distinguish between the two.
