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 available in 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.
