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 J Series, 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 switches provide:

•

Up to four uplink ports

3Copyright © 2011, Juniper Networks, Inc.

Complete Hardware Guide for EX2200 Ethernet Switches

•

12 (compact, fanless model) 24, or 48 built-in network ports with 10/100/100BASE-T
Gigabit Ethernet connectors

•

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.

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
explicitlyconfiguring a media type--copper or fiber---for the dual-purpose port using the
media-type command. For more information, see Configuring the Media Type on
Dual-Purpose Uplink Ports (CLI Procedure)

Console Port

Cable Guard

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

Support in EX2200 Switches” on page 25.

Each EX2200 switch except the EX2200-C switch model has an RJ-45 console 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 defaultsetting of a consoleport using the port-type command. See Configuring
the Console Port Type (CLI Procedure).

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 75.

Security Slots

Each EX2200-C switch model has security slots on the leftand right panels of the chassis.
The security slots allow you to lock and secure the chassis in the installation site using

Copyright © 2011, Juniper Networks, Inc.4

a standard cable lock . See “Mounting an EX2200 Switch on a Desk or Other Level Surface”

on page 75.

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.

EX2200 switches with DC power supply do not provide PoE.

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.

Chapter 1: EX2200 Switch Overview

EX2200 switches running Junos OS Release10.2 or earlier support powered devices that
comply with IEEE 802.3af (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.

Front Panel of an EX2200 Switch

The front panel of an EX2200 switch except the EX2200-C switch models consists of
the following components:

•

Network ports—depending on the switch model, either of:

•

24 or 48 10/100/1000BASE-T Gigabit Ethernet ports, with Power over Ethernet
(PoE) not available in EX2200-24T, EX2200-24T-DC, and EX2200-48T

•

24 or 48 10/100/1000BASE-T Gigabit Ethernet ports, with Power over Ethernet
(PoE) available in EX2200-24P and EX2200-48P

•

4 built-in SFP uplink ports

•

2 chassis status LEDs

•

4 port status mode LEDs

•
