J-EX8208 Switch Hardware Overview
Dell PowerConnect J-Series J-EX8208 Ethernet Switches provide high performance,
scalable connectivity, and carrier-class reliability for high-density environments such as
campus-aggregation and data-center networks. The J-EX8208 switch is a modular
system that provides high availability and redundancy for all major hardware components,
including Routing Engines, switch fabric, fan tray, and power supplies.
You can manage J-EX8208 switches using the same Junos OS interfaces that you use
for other Junos OS platforms—the Junos OS command-line interface (CLI) and the J-Web
graphical interface.

Software
The Dell PowerConnect J-EX Series Switches— PowerConnect J-Series J-EX4200 Ethernet
Switches and PowerConnect J-Series J-EX8200 Ethernet Switches—run under 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.
