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.

Understanding EX9208 Switch Component and Functionality Redundancy
The Juniper Networks EX9208 Ethernet Switches are available as fully redundant system. A redundant
EX9208 switch configuration is designed so that no single point of failure can cause the entire switch to
fail. See “EX9208 Switch Configurations” on page 27.
The following hardware components provide redundancy to an EX9208 switch:
Host Subsystem—The host subsystem consists of a Routing Engine functioning together with a Switch
•
Fabric. The host subsystem performs switching and routing functionality, system management, and
system control functions of the switch. The switch can have one or two host subsystems. If two host
subsystems are installed, one functions as the primary and the other functions as the backup. If the
primary host subsystem (or either of its components) fails, the backup can take over as the primary. To
operate, each host subsystem requires a Routing Engine module (RE module) installed directly into in a
Switch Fabric module (SF module).
If the Routing Engines are configured for graceful switchover, the backup Routing Engine automatically
synchronizes its configuration and state with the primary Routing Engine. Any update to the primary
Routing Engine state is replicated on the backup Routing Engine. If the backup Routing Engine assumes
primary role, packet forwarding continues through the switch without interruption. See “Host Subsystem
in an EX9200 Switch” on page 66.
Power supplies—In the low-line (100 V) AC power configuration, the switch contains three or four AC
•
power supplies, located horizontally at the rear of the chassis in slots PEM0 through PEM3 (left to right).
Each AC power supply provides power to all components in the switch. When three power supplies are
present, they share power almost equally within a fully populated system. Four AC power supplies
provide full power redundancy. If one power supply fails or is removed, the remaining power supplies
instantly assume the entire electrical load without interruption. Three power supplies provide the
maximum configuration with full power for as long as the switch is operational.
In the high-line (200 V) AC power configuration, the switch contains two or four AC power supplies
located horizontally at the rear of the chassis in slots PEM0 through PEM3 (left to right). Each AC power
supply provides power to all components in the switch. When two or more power supplies are present,
they share power almost equally within a fully populated system. Four AC power supplies provide full
power redundancy. If one power supply fails or is removed, the remaining power supplies instantly
assume the entire electrical load without interruption. Two power supplies provide the maximum
configuration with full power for as long as the switch is operational.
41
In the DC configuration, two power supplies are required to supply power to a fully configured switch.
One power supply supports approximately half of the components in the switch, and the other power
supply supports the remaining components. The addition of two power supplies provides full power
redundancy. If one power supply fails or is removed, the remaining power supplies instantly assume the
entire electrical load without interruption. Two power supplies provide the maximum configuration with
full power for as long as the switch is operational.
See “AC Power Supply in an EX9208 Switch” on page 53 and “DC Power Supply in an EX9208 Switch”
on page 60.
Cooling system—The cooling system in EX9208 switches consists of fan tray and air filter. The fan tray
•
contains six fans. Under normal operating conditions, the fans in the fan tray run at less than full speed.
If one of the fans fails, the host subsystem increases the speed of the remaining fans to provide sufficient
cooling for the switch indefinitely. See “EX9208 Cooling System” on page 51.

The craft interface has the following components:
Host Subsystem LEDs
Each host subsystem (RE module with SF module) has three LEDs, located on the upper left of the craft
interface, to indicate its status. The LEDs grouped with labels RE0 and RE1 show the status of the host
subsystems installed in the switch. Table 9 on page 44 describes the functions of these LEDs.

Alarm LEDs and Alarm Cutoff Button
Two large alarm LEDs are located at the upper right of the craft interface. The circular LED called major
alarm LED glows to indicate a critical condition that can result in a system shutdown. The triangular LED
called minor alarm LED glows to indicate a less severe condition (warning) that requires monitoring or
maintenance. Both LEDs can be lit simultaneously.
A condition that causes an LED to be lit also activates the corresponding alarm relay contact on the craft

The alarm cutoff/lamp test (ACO/LT) button, located next to the alarm LEDs, is a control button for alarms.
You can press the ACO/LT button to deactivate major and minor alarms. Deactivating an alarm turns off
both LEDs and deactivates the device attached to the corresponding alarm relay contact on the craft
interface.

Midplane
The midplane is located on the rear of the chassis and forms the rear of the card cage. The Switch Fabric
modules (SF modules) and line cards are installed into the midplane from the front of the chassis, and the
power supplies install into the midplane from the rear of the chassis. The cooling system components also
connect to the midplane.
The midplane performs the following major functions:
Provides a data path—Data packets are transferred across the midplane between the line cards through
•
the Switch Fabric on the host subsystem.
Distributes power—The power supplies connect to the midplane, which distributes power to all the
•
switch components.
Provides a signal path—The midplane provides the signal path to the line cards, Switch Fabric, and other
•
system components for monitoring and control of the system.

Airflow Direction in the EX9208 Switch Chassis
The air intake to cool the chassis is located on the side of the chassis next to the air filter. Air is pulled
through the chassis toward the fan tray, where it is exhausted out through the side of the chassis. The air
intake to cool the power supplies is located in the front of the chassis above the craft interface. See
Figure 18 on page 52.
Figure 18: Airflow Through the EX9208 Switch Chassis
The host subsystem monitors the temperature of switch components. Under normal operating conditions,
the fans in the fan tray run at less than full speed. If a fan fails or the ambient temperature rises above a
threshold, the speed of the remaining fans is automatically adjusted to keep the temperature within the
acceptable range. If the ambient maximum temperature specification is exceeded and the system cannot
be adequately cooled, the Routing Engine shuts down the system by disabling output power from each
power supply.
You cannot replace a single fan. If one or more fans fail, you must replace the entire fan tray.

AC Power Supply Description | 54
AC Power Supply Configurations | 55
An EX9208 switch is configurable with two, three, or four AC power supplies. The power supplies connect
to the midplane, which distributes the different output voltages produced by the power supplies to the
switch components, depending on their voltage requirements. Each power supply is cooled by its own
internal cooling system.
CAUTION: EX9208 switches use either AC or DC power supplies. Do not mix AC and
DC power supplies in a switch. The first type of power supply detected by the switch
when initially powered on determines the type of power supply allowed by the switch.
All installed power supplies of the other type are disabled by the switch. If you install
a power supply of the other type while the switch is operating, the switch disables the
power supply and generates an alarm.
This topic describes the AC power supplies in EX9208 switches.
AC Power Supply Description
54
The AC power supplies in EX9208 switches are hot-insertable and hot-removable field-replaceable units
(FRUs).
You can install up to four AC power supplies in an EX9208 switch. Power supplies are installed in the rear
of the chassis in slots PEM0 through PEM3 (left to right).
WARNING: The switch is installed in a restricted-access location. It has a separate
protective earthing terminal (sized for UNC 1/4-20 ground lugs) provided on the chassis
in addition to the grounding pin of the power supply cord. This separate protective
earthing terminal must be permanently connected to earth.
CAUTION: Before switch installation begins, ensure that a licensed electrician has
attached an appropriate grounding lug to the grounding cable that you supply. Using
a grounding cable with an incorrectly attached lug can damage the switch.
Each AC power supply weighs approximately 6.6 lb (2.99 kg) and consists of one AC appliance inlet, an
AC input switch, a fan, and LEDs to monitor the status of the power supply. See Figure 19 on page 55.
Figure 19: AC Power Supply for an EX9208 Switch
AC OK
DC OK
PS
FAIL
Each power supply has its own fan and is cooled by its own internal cooling system.
EX9208 switches support 2520 W AC power supply. The AC power supply supports both the low-voltage
line (100–120 VAC) and the high-voltage line (200–240 VAC) AC power configurations.
55
Each AC power supply has a single AC appliance inlet located on the power supply that requires a dedicated
AC power feed. We recommend that you use a customer site circuit breaker rated for 16.0 A @ 100 VAC
or 16.0 A @ 200 VAC circuit breaker minimum for each AC power supply, or as required by local code.
Doing so enables you to operate the switch in any configuration without upgrading the power infrastructure.
AC Power Supply Configurations
The EX9208 switch supports either the low-line (100–120 V) AC power configuration or the high-line
(200–240 V) AC power configuration.
In the low-line (100–120 V) AC power configuration, the EX9208 switch contains three or four AC power
•
supplies, located horizontally at the rear of the chassis in slots PEM0 through PEM3 (left to right). Each
AC power supply provides power to all components in the switch. When three power supplies are
present, they share power almost equally within a fully populated system. Four AC power supplies
provide full power redundancy. If one power supply fails or is removed, the remaining power supplies
assume the entire electrical load without interruption. Three power supplies provide the maximum
configuration with full power for as long as the switch is operational. The low-line configuration requires
three power supplies and the fourth power supply provides redundancy.
In the high-line (200–240 V) AC power configuration, the EX9208 switch contains two or four AC power
•
supplies, located horizontally at the rear of the chassis in slots PEM0 through PEM3 (left to right). In a
high-line AC power configuration, each AC power supply provides power to all components in the switch.
When two or more power supplies are present, they share power almost equally within a fully populated
system. Four AC power supplies provide full power redundancy. If one power supply fails or is removed,
the remaining power supplies assume the entire electrical load without interruption. Two power supplies
provide the maximum configuration with full power for as long as the switch is operational. In the
two-PEM high-line configuration, slots PEM0 and PEM1 or PEM2 and PEM3 are used. The high-line
configuration requires two power supplies, with the third and fourth providing redundancy.

AC Power Cord Specifications for an EX9208 Switch
Each AC power supply has a single AC appliance inlet located on the power supply that requires a dedicated
AC power feed. Most sites distribute power through a main conduit that leads to frame-mounted power
distribution panels, one of which can be located at the top of the rack that houses the switch. An AC power
cord connects each power supply to the power distribution panel.
You can order detachable AC power cords, each approximately 8 ft (2.44 m) long that supply AC power
to the switch. The C19 appliance coupler end of the cord inserts into the AC appliance inlet coupler, type
C20 (right angle) as described by International Electrotechnical Commission (IEC) standard 60320. The
plug end of the power cord fits into the power source receptacle that is standard for your geographical
location.

This topic describes the DC power supplies in EX9208 switches.
DC Power Supply Description
The DC power supplies in EX9000 switches are hot-insertable and hot-removable field-replaceable units
(FRUs).
You can install either two or four DC power supplies in an EX9208 switch. Power supplies are installed in
the rear of the chassis in slots PEM0 through PEM3 (left to right).
Each DC power supply weighs approximately 6.2 lb (2.81 kg) and consists of one DC input (–48 VDC and
return), one 70 A (–48 VDC) circuit breaker, a fan, and LEDs to monitor the status of the power supply.
See Figure 21 on page 61.
Each DC power supply has a single DC input (–48 VDC and return) that requires a dedicated circuit breaker.
We recommend you provision 60 A or 75 A per feed, depending on the selected DIP switch setting. If you
plan to operate a maximally configured DC-powered switch with DC power supplies, we recommend that
you use a dedicated customer site circuit breaker rated for 70 A (–48 VDC) minimum, or as required by
local code.
If you plan to operate a DC-powered switch at less than the maximum configuration, we recommend that
you provision a circuit breaker according to respective National Electrical Code and customer site internal
standards to maintain proper level of protection for the current specified above or each DC power supply
rated for at least 125% of the continuous current that the system draws at –48 VDC.
61
Figure 21: DC Power Supply for an EX9208 Switch
DC Power Supply Configurations
In the DC power configuration, the EX9208 switch contains either two or four DC power supplies located
at the rear of the chassis in slots PEM0 through PEM3 (left to right). You can upgrade your DC power
system from two to four power supplies.
Four power supplies provide full redundancy. If a DC power supply in a redundant configuration is removed
or fails, its redundant power supply takes over without interruption. The DC power supply in PEM2 serves
as redundant to the DC power supply in slot PEM0, and the DC power supply in PEM3 serves as redundant
to the DC power supply in slot PEM1. If only two DC power supplies are installed, they must be installed
in slots PEM0 and PEM1 or in slots PEM2 and PEM3.
Table 19 on page 62 shows the components that are powered by each DC power supply slot. It applies
to existing and high-capacity power supplies.

DC Power Supply LEDs in an EX9208 Switch
A DC power supply has three LEDs on its faceplate: POWER OK, BRKR ON, and INPUT OK LEDs. The
power supply status is also reflected in two LEDs on the craft interface. In addition, a power supply failure
triggers the major alarm LED on the craft interface.
NOTE: A host subsystem must be present for the POWER OK LED to be on.
Table 22 on page 63 describes the LEDs on a DC power supply in EX9208 switches.

Host Subsystem in an EX9200 Switch
Switching and routing functionality, system management, and system control functions of an EX9200
switch are performed by host subsystem. A host subsystem consists of a Routing Engine functioning
together with a Switch Fabric.
You can install either one or two host subsystems in the front panel of an EX9204 or an EX9208 switch.
A base configuration EX9204 and EX9208 switch has one host subsystem. A redundant configuration
EX9204 and EX9208 switch has a second host subsystem.
66
You can install either two or three host subsystems in the front panel of an EX9214 switch. A base
configuration EX9214 switch has two host subsystems. A redundant configuration EX9214 switch has a
third host subsystem.
NOTE: In EX9204 and EX9208 switches, we recommend that you install two host subsystems
for redundant protection. If you install only one host subsystem, we recommend that you install
it in slot 0. In EX9214 switches, we recommend that you install three host subsystems for
redundant protection. If you install only two host subsystems, we recommend that you install it
in slot 0 and 1.
Each host subsystem has LEDs in the craft interface that display its status. See Craft Interface in an EX9200
Switch.

Routing Engine Module in an EX9200 Switch
The Routing Engine module (RE module) is an Intel-based platform that runs Juniper Networks Junos
operating system (Junos OS). Software processes that run on the RE module maintain the routing tables,
manage the routing protocols used on the switch, control the router interfaces and some of the chassis
components, and provide the interface for system management and user access to the switch.
In an EX9204, EX9208, or EX9214 switch, you can install one or two RE modules in the Switch Fabric
modules (SF modules) that are installed in slots on the front panel of the switch. If you install two RE
modules, one functions as the primary and the other functions as the backup. If the primary RE module
fails or is removed and the backup is configured appropriately, the backup takes over as the primary. The
backup RE module is hot-insertable and hot-removable, whereas the primary RE module is only
hot-insertable. See Figure 22 on page 68 and Figure 23 on page 69. A USB port on the RE module accepts
a USB memory card that loads the Junos OS.
NOTE:
In EX9214 switches, you must install an RE module only in the SF modules installed in slots 7
•
and 8 labeled 0 and 1.
67
If you have installed only one RE module, you must power off the switch before removing the
•
RE module.
A base-configuration EX9204, EX9208, or EX9214 switch has only one RE module. See EX9204 Switch
Configurations, “EX9208 Switch Configurations” on page 27, and EX9214 Switch Configurations. You can
add a second RE module to the configuration for redundancy.
NOTE: We recommend that you install two RE modules in EX9204, EX9208, and EX9214
switches for redundancy.
The RE module performs the following functions:
Provides switching functionality to the switch through the switching plane
•
Powers the line cards on and off
•
Controls system resets and the boot sequence for the switch
•
Monitors and controls the fan speed, power status for various chassis components, and craft interface
•
LEDs
The switch ships with the RE modules preinstalled. There are two copies of the software:
One copy on the solid-state drive (SSD) in the RE module.
•
One copy on a USB flash drive that can be inserted into the slot on the RE module faceplate.

NOTE: Starting with Junos OS Release 17.1R1, EX9200 switches support the EX9200-RE2
module. The EX9200-RE2 module supports virtual machine (VM) architecture in an EX9200
switch. Only the EX9200-SF2 module supports the EX9200-RE2 module. Starting with Junos
OS Release 17.1R1, you cannot form a Virtual Chassis using an EX9200 switch.
CAUTION: The EX9200-RE module and the EX9200-RE2 module are not interoperable.
Do not install both the RE modules in the same switch chassis.
68
NOTE: Starting with Junos OS Release 16.1, you can use EX9200 switches as an aggregation
device in Junos Fusion Enterprise. Starting with Junos OS Release 17.4, you can use EX9200
switches with EX9200-RE2 module installed in it as an aggregation device in Junos Fusion
Enterprise. See Understanding Junos Fusion Enterprise Software and Hardware Requirements for
the list of line cards that support this configuration.

Switch Fabric Module in an EX9200 Switch
The Switch Fabric serves as the central nonblocking matrix through which all network data passes.
Switch Fabric modules (SF modules) are installed horizontally on the front panel of the switch chassis. You
can install either one or two SF modules in an EX9204 or EX9208 switch and two or three SF modules in
an EX9214 switch. A base-configuration EX9204 or EX9208 switch has only one SF module, and a
base-configuration EX9214 switch has two SF modules. See EX9204 Switch Configurations, “EX9208 Switch
Configurations” on page 27, or EX9214 Switch Configurations.
In EX9204 and EX9208 switches, you can add a second SF module to the configuration for host subsystem
redundancy. In EX9214 switches, you can add a third SF module to the configuration for host subsystem
redundancy. If two SF modules are installed, one SF module functions as the primary and the other functions
as the backup. If the primary SF module or its components fails or is removed, the backup module takes
the role of primary.
The Routing Engine module (RE module) installs directly into a slot on the SF module. The Switch Fabric
contains logic that determines which Routing Engine is the primary. The primary Routing Engine controls
many internal functions of the SF module.
73
The backup SF module is hot-insertable and hot-removable, but the primary SF module is only hot-insertable.
The key functions of the Switch Fabric are:
Monitor and control system functions
•
Interconnection of all line cards
•
Clocking, system resets, and booting control
•
Routing Engine carrier
•
Figure 24 on page 74 shows the original SF module, EX9200-SF.
Figure 24: SF Module EX9200-SF
g022002
74
Starting with Junos OS Release 14.1, a high-speed SF module, EX9200-SF2, is available. Compared to the
original SF module, EX9200-SF, the EX9200-SF2 offers increased bandwidth, providing higher-capacity
traffic support in settings that require greater interface density (slot and capacity scale).
The EX9200-SF2 supports all EX9200 line cards.
NOTE: When you upgrade from an EX9200-SF module to an EX9200-SF2 module in an EX9200
switch, the SF module types can coexist in the switch during the upgrade. However, you must
replace that EX9200-SF module with another EX9200-SF2 module for normal switch operation.
See “Upgrading an EX9200-SF to an EX9200-SF2” on page 217.

EX9200-SF3
Starting in Junos OS Release 20.3R1, the EX9200-SF3 Swith Fabric module is available. The EX9200-SF3
provides improved fabric performance and bandwidth capabilities for high-capacity line cards. In a redundant
configuration, the EX9200-SF3 provides fabric bandwidth of up to 1 Tbps per slot. In a nonredundant
configuration the EX9200-SF3 provides fabric bandwidth of up to 1 Tbps per slot (four fabric planes) and
1.5 Tbps per slot fabric bandwidth when all six fabric planes are used (with EX9200-15C line cards).

Routing Engine
Two Ethernet ports provide 10GbE and 1GbE SFP+ interfaces. These ports also are
connected to the Ethernet control switch, which limits the traffic for the 10GbE port
and provides security to prevent unwanted access to the control plane through the
external ports.
One RJ-45 GPS external clock interface port receives GPS and PPS timing from the GPS
external interface. A red LED indicates there is no clock present or the clock is not OK.
A green LED indicates the clock interface is active and OK. If the LED is off, the clock
interface is not enabled.
The external clock interface is on the EX9200-SF3 front panel. The clock source interface
receives GPS and PPS timing from the GPS external interface.
The clock module performs clock monitoring, filtering, and holdover on the centralized
fabric card. This centralized clocking architecture also provides clock cleanup and
distribution.
The in-system Routing Engine can support any new Routing Engine that conforms to
the standard modular Routing Engine I/O interface and form factor.
NOTE: When a Routing Engine is not installed in the EX9200-SF3, you need to cover
the empty slot with a blank panel.
Hot-swappable
Redundancy
The EX9200-SF3 and associated Routing Engine assembly are hot-swappable. The
system software provides a mechanism to shut down the Routing Engine/EX9200-SF3.
The system software also provides a method to reset or reboot the Routing
Engine/EX9200-SF3. This support is provided through CLI commands and various
hardware support circuits.
NOTE: Before removing the module, you must bring the Routing Engine offline to avoid
corrupting the hard drive.
See “Upgrading to an EX9200-SF3” on page 221 for details.System upgrade capabilities
With three EX9200-SF3 Switch Fabric modules installed, the EX9214 provides 2 + 1
redundancy. With two EX9200-SF3s installed, the EX9204 and EX9208 provide 1 + 1
redundancy.

EX9200-SF3 Fabric Bandwidth Performance and Redundancy
EX9214 Switches:
The EX9214 system can contain up to three EX9200-SF3s to provide a total of six switch fabric planes
•
for packet forwarding among the MPCs. Two fabric planes per EX9200-SF3s are required. To achieve
full fabric bandwidth performance, three EX9200-SF3s must be installed in the EX9214 chassis.
Two chassis slots are provided in the center of the EX9214 chassis in slots 6 and 7 (also designated as
•
slot SF0 and slot SF1) for two EX9200-SF3s, each equipped with a Routing Engine.
To provide 2 + 1 fabric redundancy for an EX9214, a third EX9200-SF3 must be installed in slot 8 (also
•
designated as slot SF2).
Slot 8 in the EX9214 chassis is a dual-purpose slot, and supports either an EX9200-SF3 or a line card.
•
When the EX9200-SF3/Routing Engine are plugged into slot 8, the Routing Engine is powered down
and does not provide any control functionality for the board or the EX9214. The fabric-only LED on the
card faceplate will be lit when an EX9200-SF3/Routing Engine assembly is plugged into slot 8.
Once redundancy is configured, the primary EX9200-SF3 controls the chassis.
•
Graceful upgrades can be achieved on a non-primary redundant EX9200-SF3.
•
In a redundant configuration, the non-primary redundant Routing Engine can be removed or installed
•
without affecting the switching plane functionality on the EX9200-SF3 in which it resides.
80
In a nonredundant configuration, all six fabric planes will be in active mode for increased fabric bandwidth.
•
There is one physical switch fabric per EX9200-SF3 and it acts as two virtual planes in the EX9214.
•
EX9204 and EX9208 Switches:
You can install either one or two EX9200-SF3s in the EX9204 and EX9208 chassis in the slots labeled
•
0 and 1.
The EX9200-SF3 in slot 0 (SF0) provides two fabric planes; the EX9200-SF3 in slot 1 (SF1) provides four
•
fabric planes. A total of six fabric planes are available in the EX9204 and EX9208.
In a redundant configuration, two fabric planes on the first EX9200-SF3 and two fabric planes on the

other EX9200-SF3 will be in active mode.
There is one physical switch fabric per EX9200-SF3, and it acts as four virtual planes in the EX9204 and
•
EX9208.
Two EX9200-SF3 modules installed in the EX9204 and EX9208 are required for 1 + 1 redundancy. To
provide 1 + 1 fabric redundancy, there must be an EX9200-SF3 installed in slot 1.
NOTE:
If SF0 fails, SF1 will be automatically configured with four fabric planes active. In this failover
•
scenario, the EX9200-SF3 will support full line rate 100 percent redundancy.
If SF1 fails, SF0 has only two available fabric planes; therefore, in this failover mode, the line
•
rate will drop to 50 percent.

You can install SFP+ and QSFP+ transceivers in any combination in the ports on the line card. The ports
are divided into two port groups. The twelve 10-Gigabit Ethernet ports labeled 0/0 through 0/11 form
PIC 0 and twelve 10-Gigabit Ethernet ports labeled 1/0 through 1/11 form PIC 1; PIC 0 and PIC 1 form
one port group. The three 40-Gigabit Ethernet ports labeled 2/0 through 2/2 form PIC 2 and three
40-Gigabit Ethernet ports labeled 3/0 through 3/2 form PIC 3; PIC 2 and PIC 3 form the other port group.
The ports in each port group share 240 gigabits of bandwidth. Thus, you can transmit up to 240 gigabits
of traffic through a port group, without packet drop.
PIC 0 and PIC 1 are activated by default. If you deactivate both PIC 0 and PIC 1, PIC 2 and PIC 3 are
automatically activated. Similarly, if you deactivate both PIC 2 and PIC 3, PIC 0 and PIC 1 are automatically
activated. You can choose to activate only one of the PICs and keep the other inactive. To deactivate an
active PIC, use the power command.

Line Card Components
The EX9200-12QS line card has:
Twelve rate-selectable Gigabit Ethernet ports. All ports can operate at 10-Gbps and 40-Gbps speeds.
•
The ports are configured to operate at 10-Gbps speed by default. The ports labeled 0/2, 0/5, 1/2, and
1/5 (see Figure 34 on page 97) can operate at 100-Gbps speed also. You can configure the port speed
by using the following command:
user@host# set chassis fpc fpc-slot pic pic-number pic-mode pic-speed number of ports
number-of-active-physical-ports
You can configure a port to operate at 10-Gbps speed. If you configure the ports to operate at 10-Gbps
•
speed, each port operates as four 10-Gbps interfaces.
You can configure a port to operate at 40-Gbps speed and install a 40-gigabit QSFP+ transceiver in
•
the port.
You can configure the ports labeled 0/2, 0/5, 1/2, and 1/5 (see Figure 34 on page 97) to operate at
•
100-Gbps speed and install 100-gigabit QSFP+ transceivers in these ports.

Twelve dust covers for the ports
•
Line card LED—An LED labeled OK/FAIL, which indicates the status of the line card. See “Line Card LED
•
in an EX9200 Switch” on page 111.
Network port LED—Four LEDs for each network port, the Link/Activity LED, which indicates the link
•
status and activity on the port. See “Network Port LEDs on Line Cards in an EX9200 Switch” on page 111.
There are four LEDs labeled 0, 1, 2, and 3 for each port (see Figure 34 on page 97). If a port is configured
to operate at 10-Gbps speed, four 10-Gbps interfaces are created and the LEDs labeled 0, 1, 2, and 3
for that port becomes operational. Each of these LEDs indicates the link/activity on each interface on
the corresponding port. If a port is configured to operate at 40-Gbps speed, the LED labeled 0 for that
port becomes operational. If the ports labeled 0/2, 0/5, 1/2, and 1/5 are configured to operate at
100-Gbps speed, the LED labeled 3 for each of these ports becomes operational.
You can find the list of transceivers supported on the EX9200-12QS line card at the Hardware Compatibility
Tool page for the EX9200-12QS line card.
The ports are divided into two port groups. The six ports labeled 0/0 through 0/5 form one port group,
PIC 0. The six ports labeled 1/0 through 1/5 form the other port group, PIC 1. The ports in each group
share 240 gigabits of bandwidth. Thus, you can transmit up to 240 gigabits of traffic through a port group
without packet drop.

The line cards in EX9200 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 on the front
of the switch chassis. Line cards are hot-insertable and hot-removable: You can remove and replace them
without powering off the switch or disrupting switch functions.

256 bytes through 16,000 bytes for transit traffic,
and from 256 bytes through 9500 bytes for
host-bound packets.
NOTE:
For the EX9200-15C line card to be operational, you must install the EX9200-SF3 Switch
•
Fabric module (SF module) in the switch. See “EX9200-SF3 Module in an EX9200 Switch” on
page 77.
To achieve maximum line-rate performance, the line card’s fabric redundancy mode must be
•
configured in increased bandwidth mode.
To achieve maximum performance, the following number of EX9200-SF3 SF modules must
•
be installed in the system:
EX9214—Three EX9200-SF3 SF modules
•
EX9204 and EX9208—Two EX9200-SF3 SF modules
