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;
}
}
} }
xiv
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]
xv
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.

Simplified network architecture—EX9204 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 EX9204 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 EX9204 switches to collapse core and aggregation layers. In combined campus and data center environments, EX9204 switches consolidate network layers to simplify the network architecture and operations.
Support for MACsec—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.
Software

Host Subsystem
24
Switching and routing functionality, system management, and system control functions of an EX9204 switch are performed by the host subsystem. The host subsystem consists of a Routing Engine functioning together with a Switch Fabric.
An EX9204 is a 4-slot chassis that provides two dedicated slots—labeled 1 and 2—for line cards, one dedicated slot—labeled 0—for a host subsystem, and one multifunction slot—labeled 1|0—for either a line card or a host subsystem.
You can install either one or two host subsystems in an EX9204 switch. A base-configuration EX9204 switch has one host subsystem. A redundant-configuration EX9204 switch has a second host subsystem. For more information, see “EX9204 Switch Configurations” on page 27.
Line Cards
Line cards are field-replaceable units (FRUs) that you can install in the line card slots and in the multifunctional slot on the front of the switch chassis. All line cards are hot-removable and hot-insertable.
You can install up to three line cards in an EX9204 switch. Each EX9204 switch has two dedicated line card slots—labeled 1 and 2—and a multifunction slot—labeled 1|0—that you can use for either a line card or a host subsystem.
The line cards in EX9204 switches combine a Packet Forwarding Engine and Ethernet interfaces in a single assembly. Table 3 on page 25 lists the line cards available for EX9204 switches.

Cooling System
The cooling system in an EX9204 switch is a field-replaceable unit (FRU). It consists of a hot-removable and hot-insertable fan tray. The fan tray contains three fans. The fan tray installs vertically on the right back of the chassis and provides side-to-side chassis cooling. See “EX9204 Cooling System” on page 49.
Power Supplies
Power supplies for the EX9204 switch are fully redundant, load-sharing, and hot-removable and hot-insertable FRUs. Each EX9204 switch chassis can hold up to four AC or up to two DC power supplies.
Table 4 on page 26 shows the details of the power supplies available for EX9204 switches.

Field-Replaceable Units in an EX9200 Switch

Field-replaceable units (FRUs) are switch components that you can replace at your site. The EX9200 switch uses the following types of FRUs:
Hot-insertable and hot-removable—You can remove and replace these components without powering
off the switch or disrupting the switching function.
Hot-pluggable—You can remove and replace these components without powering off the switch, but
the switching function is interrupted until you replace the component.
Table 8 on page 38 lists the FRUs for the EX9200 switch and their types.

Understanding EX9204 Switch Component and Functionality Redundancy

The Juniper Networks EX9204 Ethernet Switches are available as fully redundant system. A redundant EX9204 switch configuration is designed so that no single point of failure can cause the entire switch to fail. See “EX9204 Switch Configurations” on page 27.
The following hardware components provide redundancy to an EX9204 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 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 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.
In the high-line (200 V) AC power configuration, the switch contains one or two AC power supplies located horizontally at the rear of the chassis in slots PEM0 and PEM2 (left to right). Each AC power supply provides power to all components in the switch. Each AC power supply provides power to all components in the switch. When two power supplies are present, they share power almost equally within a fully populated system. If one power supply fails or is removed, the remaining power supply assumes the entire electrical load without interruption. One power supply can provide the maximum configuration with full power for as long as the switch is operational.

See “AC Power Supply in an EX9204 Switch” on page 51.
In the DC configuration, the switch comes with two DC power supply preinstalled. one power supply is required to supply power to a fully configured switch and the second power supply provides full power redundancy. If one power supply fails or is removed, the second power supply instantly assume the entire electrical load without interruption. One power supply provides the maximum configuration with full power for as long as the switch is operational. See “DC Power Supply in an EX9204 Switch” on
page 59.
Cooling system—The cooling system in EX9204 switches consists of fan tray and air filter. The fan tray
contains three 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 “EX9204 Cooling System” on page 49.

Midplane in an EX9200 Switch

ESD
g022027
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.
Figure 9 on page 47 shows the midplane in an EX9204 switch. Figure 10 on page 48 shows the midplane

Fan Tray

The fan tray is a hot-insertable and hot-removable field-replaceable unit (FRU) and contains three fans. The fan tray and air filter install vertically in the rear of the switch. See Figure 12 on page 49 and
Figure 13 on page 50.

Figure 13: Air Filter for an EX9204 Switch

Airflow Direction in the EX9204 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 14 on page 50.
50
Figure 14: Airflow Through the EX9204 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 in an EX9204 Switch

IN THIS SECTION
AC Power Supply Description | 52
AC Power Supply Configurations | 53
An EX9204 switch is configurable with one, two, 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: EX9204 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 EX9204 switches:
AC Power Supply Description
The AC power supplies in EX9204 switches are hot-insertable and hot-removable field-replaceable units (FRUs).
You can install up to four AC power supplies in an EX9204 switch. Power supplies are installed in the rear of the chassis in slots PEM0 through PEM3 (left to right).
52
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 you begin installing the switch, 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 15 on page 53.
Figure 15: AC Power Supply for an EX9204 Switch
AC OK
DC OK
PS
FAIL
Each power supply has its own fan and is cooled by its own internal cooling system.
EX9204 switches support 2520 W AC power supply. The AC power supply supports the low-line (100–120 VAC) and the high-line(200–240 VAC) AC power configurations.
53
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 EX9204 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 EX9204 switch contains either two AC power
supplies in base AC configuration, located horizontally at the rear of the chassis in slots PEM0 and PEM1 (left to right); or four AC power supplies in the redundant AC configuration, located in slots PEM0 through PEM3 (left to right). Each AC power supply provides power to all components in the switch.
The low-line configuration requires minimum two power supplies to provide the maximum configuration with full power for as long as the switch is operational. When only two power supplies are present, they share power almost equally within a fully populated system and removing one of the power supply will disturb switch functions. 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.
In the high-line (200–240 V) AC power configuration, the EX9204 switch contains either one power
supply in the base AC configuration, located horizontally in the slot PEM0; or two power supplies in the redundant AC configuration, located in slots PEM0 and PEM2 (left to right). In a high-line AC power configuration, each AC power supply provides power to all components in the switch.
In high-line configuration, one power supply provide the maximum configuration with full power for as long as the switch is operational. Two power supplies provide full power redundancy; if one power
supply fails or is removed, the remaining power supply assume the entire electrical load without interruption. The high-line configuration requires one power supply, with the second providing redundancy. See “AC Power Supply Specifications for EX9204 Switches” on page 55.
Ensure that you install sufficient number of power supplies to provide the power necessary for the line cards you install in the switch. See Power Requirements for EX9200 Switch Components to know the power required by each component in the switch and “AC Power Supply Specifications for EX9204 Switches” on
page 55 for the power supply specifications including the output power provided by the power supplies.
Table 15 on page 54 shows an example for power requirement calculation. To install three EX9200-32XS
line cards in the switch, the power required is 2300 W, calculated as shown in the table:
Table 15: Example—Power Required to Install Three EX9200-32XS Line Cards in an EX9204 Switch

410 WBase system
150 W1 SF module
54
90 W1 RE module
1650 W3 EX9200-32XS line cards
2300 WTotal
The output power provided by each low-voltage line power supply is 1167 W and the output power provided by each high-voltage line power supply is 2050 W.
Starting in Junos OS Release 18.4R1, on EX9204 switches, the enhanced AC PEM in the high-line power configuration supplies a power output of 2400 W. On Junos OS versions prior to 18.4R1, the PEM provided 2050 W of power output.
Therefore, to provide sufficient power to support three EX9200-32XS line cards, you must install at least two low-voltage line or high-voltage line power supplies in the switch.

AC Power Cord Specifications for an EX9204 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 EX9204 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 two DC power supplies in an EX9204 switch. Power supplies are installed in the rear of the chassis in slots PEM0 and PEM2 (left to right).
60
A 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 17 on page 61.
Each DC power supply has a single DC input (–48 VDC and return) that requires a dedicated circuit breaker. We recommend that 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.
Figure 17: DC Power Supply for an EX9204 Switch
DC Power Supply Configurations
In the DC power configuration, the EX9204 switch comes with two DC power supplies located at the rear of the chassis in slots PEM0 and PEM2 (left to right). One power supply provide the maximum configuration with full power for as long as the switch is operational. Two power supplies provide full redundancy; if one power supply fails or is removed, the redundant power supply takes over without interruption. . A single DC power supply provides power to all components and the second DC power supply provides redundancy. See “DC Power Supply Specifications for EX9204 Switches” on page 62.
61
NOTE: Move the input switch to 0 for 60 A input and position 1 for 70 A input.
NOTE: Do not set the input mode switch if the power supply is installed in the chassis. If the
power supply is already installed, you must remove it before setting the input mode switch.
Ensure that you install sufficient number of power supplies to provide the power necessary for the line cards you install in the switch. See Power Requirements for EX9200 Switch Components to know the power required by each component in the switch and “DC Power Supply Specifications for EX9204 Switches”
on page 62 for the power supply specifications including the output power provided by the power supplies.
Table 20 on page 62 shows an example for power requirement calculation. To install three EX9200-32XS
line cards in the switch, the power required is 2300 W, calculated as shown in the table:

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.
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.
66
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 18 on page 68 and Figure 19 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.
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” on page 27, EX9208 Switch Configurations, and EX9214 Switch Configurations. You can add
a second RE module to the configuration for redundancy.
67
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.
The RE module boots from the storage media in the following order: the USB device (if present), then the SSD, and finally the LAN.

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.
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” on page 27, EX9208 Switch Configurations, 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.
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

Figure 20 on page 73 shows the original SF module, EX9200-SF.
Figure 20: SF Module EX9200-SF
73
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 214.
Figure 21 on page 74 shows the high-speed SF module, EX9200-SF2.

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).

External clock interface
Centralized Stratum3E clock module
In-system removable 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 217 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.
79
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.

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 30 on page 96) 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 30 on page 96) to operate at
100-Gbps speed and install 100-gigabit QSFP+ transceivers in these ports.
97
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 110.
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 110.
There are four LEDs labeled 0, 1, 2, and 3 for each port (see Figure 30 on page 96). 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.
