J-EX4200 Switches Hardware Overview
J-EX Series Switches provide scalable connectivity for the enterprise market, including
branch offices, campus locations, and data centers. The switches run under 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 J-EX
Series switches also runs on Dell PowerConnect J-SRX Series Services Gateways.
You can interconnect multiple J-EX4200 chassis 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, the switches are used in large branch
offices, campus wiring closets, and top-of-rack locations in a data center.
