EX-series Switch Hardware Overview
EX-series switches provide scalable connectivity for the enterprise market, including
branch offices, campus locations, and data centers. The switches run under the
JUNOS software, which provides Layer 2 and Layer 3 switching, routing, and security
services. The same JUNOS code base that runs on EX-series switches also runs on
all Juniper Networks J-series, M-series, MX-series, and T-series routing platforms.

EX-series Switch Types
EX-series switches are available in two product lines:
■ EX 3200 switches—Typically, you deploy these switches in branch environments
or wiring closets.
■ EX 4200 switches—You can interconnect EX 4200 switches to form a virtual
chassis that operates as a single network entity. You can deploy these switches
wherever you need a high density of Gigabit Ethernet ports (24 to 480 ports),
redundancy, or the ability to span a single switch across several wiring closets.
Typically, EX 4200 switches are used in large branch offices, campus wiring
closets, and top-of-rack locations in a data center.
