Juniper Networks EX9208 Ethernet Switches provide high performance, scalable connecvity, and
carrier-class reliability for high-density environments such as campus-aggregaon 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 Roung Engine
modules (RE modules), Switch Fabric modules (SF modules), fan tray (redundant fans), and power
supplies.
2

You can manage EX9208 switches by using the same interfaces that you use for managing other devices
running the Juniper Networks Junos operang system (Junos OS)—the CLI, the Network and Security
Manager (NSM), and Junos Space.
Benets
Simplied network architecture—EX9208 switches deliver a simple, secure, virtualized network
environment that increases business agility. They are ideal for simplifying campus, data center, and
combined campus and data center network environments by collapsing network layers. In a mulchassis
link aggregaon (MC-LAG) conguraon in the campus, you can use EX9208 switches to eliminate
Spanning Tree Protocol (STP); they collapse the core and aggregaon layers, thereby simplifying the
network architecture and network operaons. In a data center, you can use EX9208 switches to collapse
core and aggregaon layers. In combined campus and data center environments, EX9208 switches
consolidate network layers to simplify the network architecture and operaons.
MACsec support—EX9200-40F-M and EX9200-40XS line cards and EX9200-20F-MIC for EX9200-
MPC line card supports IEEE 802.1AE MACsec with AES-256 bit encrypon, ensuring link-layer data
condenality, data integrity, and data origin authencaon.
Soware
Juniper Networks EX Series Ethernet Switches run Junos OS, which provides Layer 2 and Layer 3
switching, roung, and security services.

Chassis Physical Specicaons
The EX9208 switch is eight rack units (8 U) in size. Five EX9208 switches can t in a standard 48 U rack.
Each EX9208 switch is designed to opmize rack space and cabling. See Figure 1 on page 4, Figure 2
on page 4, and Figure 3 on page 5.

Figure 3: Rear View of an EX9208 Switch with DC Power Supplies
Host Subsystem
Switching and roung funconality, system management, and system control funcons of an EX9208
switch are performed by the host subsystem. The host subsystem consists of a Roung Engine
funconing together with a Switch Fabric.
You can install either one or two host subsystems in the slots labeled 0 and 1 in the front panel of the
chassis. A base-conguraon EX9208 switch has one host subsystem. A redundant-conguraon
EX9208 switch has a second host subsystem. For more informaon, see "EX9208 Switch
Conguraons" on page 8.
Line Cards
The EX9208 switch has six horizontal line card slots and supports line rate for each line card. The line
cards in EX9208 switches combine a Packet Forwarding Engine and Ethernet interfaces in a single
assembly. Line cards are eld-replaceable units (FRUs) that you can install in the line card slots—labeled
0 through 5—on the front of the switch chassis. All line cards are hot-removable and hot-insertable.
Table 1 on page 6 lists the line cards available for EX9208 switches.

Cooling System
The cooling system in an EX9208 switch is a eld-replaceable unit (FRU). It consists of a hot-removable
and hot-insertable fan tray. The fan tray contains six fans. The fan tray installs vercally on the right
back of the chassis and provides side-to-side chassis cooling. See "EX9208 Cooling System" on page
39.
Power Supplies
Power supplies for the EX9208 switch are fully redundant, load-sharing, and hot-removable and hot-
insertable FRUs. Each EX9208 switch chassis can hold up to four AC or DC power supplies.
Table 2 on page 7 shows the details of the power supplies available for EX9208 switches.

240 VAC) AC power supplies. An AC-powered, redundant-conguraon EX9208 switch ships with four
low-line (100–120 VAC) or four high-line (200–240 VAC) AC power supplies. See "AC Power Supply in
an EX9208 Switch" on page 43.
A DC-powered, redundant-conguraon EX9208 switch ships with four DC power supplies. See "DC
