EX4200 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 devices.

EX4200 Switches
Juniper Networks EX4200 Ethernet Switches provide connectivity for medium- and
high-density environments and scalability for growing networks. These switches can be
deployed wherever you need high density of Gigabit Ethernet ports (24 to 480 ports) or
redundancy. Typically, EX4200 switches are used in large branch offices, campus wiring
closets, and data centers where they can be positioned as the top device in a rack to
provide connectivity for all the devices in the rack.
You can connect individual EX4200 switches together to form one unit and manage the
unit as a single chassis, called a Virtual Chassis. You can add more member switches to
the Virtual Chassis as needed, up to a total of 10 members.
EX4200 switches are availablein models with 24 or 48 ports with either all ports equipped
for Power over Ethernet (PoE/PoE+)or only 8 ports equipped for PoE. All models provide
ports that have 10/100/1000Base-T Gigabit Ethernet connectors and optional 1-gigabit
small form-factor pluggable (SFP) transceivers, 10-gigabit small form-factor pluggable
(SFP+) transceivers, or 10-gigabit small form-factor pluggable (XFP) transceivers for
use with fiber connections.
3Copyright © 2017, Juniper Networks, Inc.
EX4200 Switch Hardware Guide
Additionally, a 24-port model provides 100Base-FX/1000Base-X SFP ports. This model
is typically used as a small distribution switch.
All EX4200 switches have dedicated 64-Gbps Virtual Chassis ports (VCPs) that enable
you to connect the switches to each other.Youcan also use optional uplink module ports
to connect members of a Virtual Chassis across multiple wiring closets.
To provide carrier-class reliability, EX4200 switches include:
•
Dual redundant power supplies that are field-replaceable and hot-swappable. An
optional additional connection to an external power source is also available.
•
A field-replaceable fan tray with three fans. The switch remains operational if a single
fan fails.
•
RedundantRouting Engines in a Virtual Chassis configuration.This redundancy enables
graceful Routing Engine switchover (GRES) and nonstop active routing (NSR).
•
Junos OS with its modular design that enables failed system processes to gracefully
restart.
EX4200 switches have these features:
•
Run under Junos OS for EX Series switches
•
Have options of 24-port and 48-port models
•
Have options of full (all ports) PoE/PoE+ capability or partial (8 ports) PoE capability
•
Have optional uplink modules that provide connection to distribution switches
Uplink Modules
Optional uplink modules are available for all EX4200 switches. Uplink modules provide
two ports for installing 10-gigabit small form-factor pluggable (XFP) transceivers, four
ports for installing 1-gigabit small form-factor pluggable (SFP) transceivers, two ports
for installing 10-gigabit small form-factor pluggable (SFP+) transceivers. You can use
XFP, SFP, or SFP+ ports to connect an access switch to a distribution switch or to
interconnect member switches of a Virtual Chassis across multiple wiring closets.
EX4200 switches also support an SFP+ Media Access Control Security (MACsec) uplink
module starting in Junos OS Release 13.2X50-D10. The SFP+ MACsec module provides
four MACsec-capable ports and can be configured to support up to four 1-gigabit SFP
transceivers or up to two 10-gigabit small form-factor pluggable (SFP+) transceivers.
Power over Ethernet Ports
PoEports provide electrical current to devices through the network cables so that separate
power cords for devices such as IP phones, wireless access points, and security cameras
are unnecessary.
PoE was first defined in the IEEE 802.3af standard. Starting with Junos OS Release 11.1,
EX4200 switches support enhanced PoE, a Juniper Networks extension to the IEEE
302.3af PoE standard that increasesthe amount of power per PoE port. A laterstandard,
Copyright © 2017, Juniper Networks, Inc.4
Chapter 1: System Overview
IEEE 802.3at, defined PoE+. An IEEE 802.3af powered device operates normally when
connected to an IEEE 802.3at (PoE+) power sourcing equipment.
EX4200 switches with an AC power supply installed have options of full (all 24 or 48
ports) PoE/PoE+ capability or partial (8 ports) PoE capability. EX4200 switches with a
DC power supplyinstalleddo not providePoE. For more information, see“EX4200 Switch
Models” on page 5.
Full PoE/PoE+ models are primarily used in IP telephony environments. Partial PoE
models are used in environments where, for example,only a few ports for wireless access
points or security cameras are required.

EX4200 Switch Models
The EX4200 switch is available with 24 or 48 ports and with partial or full Power over
Ethernet (PoE) capability. EX4200 switches with a DC power supply installed do not
provide PoE.
NOTE: This topic uses the term PoE to refer to both PoE and PoE+ unless
there is a need to distinguish between the two.
