EX9208 Switch Hardware Overview
Juniper Networks EX9208 Ethernet Switches provide high performance, scalable
connectivity, and carrier-class reliability for high-density environments such as
campus-aggregation and data-center networks. The EX9208 switch has a throughput
of up to 4.8 terabits per second (Tbps) or up to 240 gigabits per second (Gbps) per slot
full duplex. The EX9208 switch is a modular system that provides high availability and
redundancy for all major hardware components, including Routing Engine modules (RE
modules), Switch Fabric modules (SF modules), fan tray (redundant fans), and power
supplies.
You can manage EX9208 switches by using the same interfacesthat you use for managing
other devices running the Juniper Networks Junos operating system (Junos OS)—the CLI,
the Network and Security Manager (NSM), and Junos Space.

Software
Juniper Networks EX Series Ethernet Switches run Junos OS, which provides Layer 2 and
Layer 3 switching, routing, and security services.
Chassis Physical Specifications
The EX9208 switch is eight rack units (8 U) in size. Five EX9208 switches can fit in a
standard 48 U rack. Each EX9208 switch is designed to optimize rack space and cabling.
