Documentation and Release Notes
To obtain the most current version of all Juniper Networks®technical documentation, see the product
documentation page on the Juniper Networks website at https://www.juniper.net/documentation/.
If the information in the latest release notes differs from the information in the documentation, follow the
product Release Notes.
Juniper Networks Books publishes books by Juniper Networks engineers and subject matter experts.
These books go beyond the technical documentation to explore the nuances of network architecture,
deployment, and administration. The current list can be viewed at https://www.juniper.net/books.
Using the Examples in This Manual
If you want to use the examples in this manual, you can use the load merge or the load merge relative
command. These commands cause the software to merge the incoming configuration into the current
candidate configuration. The example does not become active until you commit the candidate configuration.
If the example configuration contains the top level of the hierarchy (or multiple hierarchies), the example
is a full example. In this case, use the load merge command.
If the example configuration does not start at the top level of the hierarchy, the example is a snippet. In
this case, use the load merge relative command. These procedures are described in the following sections.
Merging a Full Example
To merge a full example, follow these steps:
1. From the HTML or PDF version of the manual, copy a configuration example into a text file, save the
file with a name, and copy the file to a directory on your routing platform.
For example, copy the following configuration to a file and name the file ex-script.conf. Copy the
ex-script.conf file to the /var/tmp directory on your routing platform.
system {
scripts {
commit {
file ex-script.xsl;
}
}
}
interfaces {
fxp0 {
disable;
unit 0 {
family inet {
address 10.0.0.1/24;
}
}
}
}
xv
2. Merge the contents of the file into your routing platform configuration by issuing the load merge
configuration mode command:
[edit]
user@host# load merge /var/tmp/ex-script.conf
load complete
Merging a Snippet
To merge a snippet, follow these steps:
1. From the HTML or PDF version of the manual, copy a configuration snippet into a text file, save the
file with a name, and copy the file to a directory on your routing platform.
For example, copy the following snippet to a file and name the file ex-script-snippet.conf. Copy the
ex-script-snippet.conf file to the /var/tmp directory on your routing platform.
commit {
file ex-script-snippet.xsl; }
2. Move to the hierarchy level that is relevant for this snippet by issuing the following configuration mode
command:
[edit]
user@host# edit system scripts
[edit system scripts]
xvi
3. Merge the contents of the file into your routing platform configuration by issuing the load merge
relative configuration mode command:
[edit system scripts]
user@host# load merge relative /var/tmp/ex-script-snippet.conf
load complete
For more information about the load command, see CLI Explorer.

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 interfaces that 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.

Simplified 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 multichassis link aggregation
(MC-LAG) configuration in the campus, you can use EX9208 switches to eliminate Spanning Tree Protocol
(STP); they collapse the core and aggregation layers, thereby simplifying the network architecture and
network operations. In a data center, you can use EX9208 switches to collapse core and aggregation layers.
In combined campus and data center environments, EX9208 switches consolidate network layers to simplify
the network architecture and operations.
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 encryption, ensuring link-layer data
confidentiality, data integrity, and data origin authentication.

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. See Figure 1 on page 23,
Figure 2 on page 24, and Figure 3 on page 24.

Host Subsystem
Switching and routing functionality, system management, and system control functions of an EX9208
switch are performed by the host subsystem. The host subsystem consists of a Routing Engine functioning
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-configuration EX9208 switch has one host subsystem. A redundant-configuration EX9208
switch has a second host subsystem. For more information, see “EX9208 Switch Configurations” on page 27.
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 field-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 3 on page 25
lists the line cards available for EX9208 switches.

The cooling system in an EX9208 switch is a field-replaceable unit (FRU). It consists of a hot-removable
and hot-insertable fan tray. The fan tray contains six fans. The fan tray installs vertically on the right back
of the chassis and provides side-to-side chassis cooling. See “EX9208 Cooling System” on page 51.
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 4 on page 26 shows the details of the power supplies available for EX9208 switches.
Table 4: Power Supplies Supported on EX9208 Switches
Output PowerInput VoltagePower Supply

2050 WHigh-voltage line (200–240 VAC)
2400 W to 2600 W–40 VDC through –70 VDC2400 W DC
A base-configuration EX9208 switch ships with three low-line (100–120 VAC) or two high-line
(200–240 VAC) AC power supplies. An AC-powered, redundant-configuration 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 53.
A DC-powered, redundant-configuration EX9208 switch ships with four DC power supplies. See “DC
Power Supply in an EX9208 Switch” on page 60.
CAUTION: Do not mix AC and DC power supplies in the same chassis.
