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;

}

} }

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 EX9214 Ethernet Switches provide high performance, scalable connectivity, and carrier-class reliability for high-density environments such as campus-aggregation and data-center networks. The EX9214 switch has a throughput of up to 13.2 terabits per second (Tbps) or up to 240 gigabits per second (Gbps) per slot full duplex. The EX9214 switch is a modular system that provides high availability and redundancy for all major hardware components, including Routing Engine module (RE module), Switch Fabric module (SF module), fan trays, and power supplies.

You can manage EX9214 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.

Benefits of the EX9214 Switch

Simplified network architecture—EX9214 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 EX9214 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, EX9214 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.

Software

The 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 EX9214 switch is 16 rack units (16 U) in size. Three EX9214 switches can fit in a standard 48 U rack. Each EX9214 switch is designed to optimize rack space and cabling.

See Figure 1 on page 24, Figure 2 on page 25, and Figure 3 on page 25.

Host Subsystem

Switching and routing functionality, system management, and system control functions of an EX9214 switch are performed by the host subsystem. The host subsystem consists of a Routing Engine functioning together with a Switch Fabric.

You must install either two or three host subsystems in the slots 7 through 9—labeled 0, 1, and 2 | 6—in the front panel of the chassis. A base-configuration EX9214 switch has two host subsystems. A redundant-configuration EX9214 switch has a third host subsystem. For more information, see “EX9214

Switch Configurations” on page 28.

Line Cards

The EX9214 switch has 12 vertical line card slots. The line cards for EX9214 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 1 through 6 (labeled 0 through 5) and 9 through 14 (labeled 6 through 11) on the front of the switch chassis. All line cards are hot-removable and hot-insertable. You can install a line card or a host subsystem in slot 9—labeled 2 | 6.

Table 3 on page 26 lists the line cards available for EX9214 switches.

Cooling System

The cooling system in an EX9214 switch is a field-replaceable unit (FRU). It consists of two fully redundant hot-removable and hot-insertable fan trays and an air filter and provides front-to-back chassis cooling. See “EX9214 Cooling System” on page 53.

Power Supplies

Power supplies for the EX9214 switch are fully redundant, load-sharing, and hot-removable and hot-insertable FRUs. Each EX9214 switch chassis can hold up to four AC or DC power supplies. The power supplies connect to the midplane, which distributes the power to the switch components depending on their voltage requirements.

Table 4 on page 28 shows the details of the power supplies available for EX9214 switches.

An AC-powered, base-configuration EX9214 switch ships with three 200–240 VAC AC power supplies. An AC-powered, redundant-configuration EX9214 switch ships with four 200–240 VAC AC power supplies. See “AC Power Supply in an EX9214 Switch” on page 56.

A DC-powered, redundant-configuration EX9214 switch ships with four –40 VDC through –72 VDC DC power supplies. See “DC Power Supply in an EX9214 Switch” on page 64.

CAUTION: Do not mix different types of power supplies (AC and DC) in the same

chassis.

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 41 lists the FRUs for the EX9200 switch and their types.

Understanding EX9214 Switch Component and Functionality Redundancy

The Juniper Networks EX9214 Ethernet Switch is available as a fully redundant system. A redundant EX9214 switch configuration is so designed that no single point of failure can cause the entire switch to fail. See “EX9214 Switch Configurations” on page 28.

The following hardware components provide redundancy to an EX9214 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. Either two or three host subsystems can be installed in the switch. 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 takes 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).

You can install up to 12 line cards in an EX9214 switch. You can install either a line card or an SF module in the slot nine (labeled 2 | 6). If you install a line card in slot nine (labeled 2 | 6), redundancy is not available for the host subsystem.

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.

AC power supplies—You can install either two or four AC power supplies vertically at the rear of the

•

chassis in slots PEM0 through PEM3 (left to right). The power supplies operate in two zones: power supplies in slots PEM0 and PEM2 provide power to the lower fan tray, line-card slots 6 through 11, and switch fabric slots 1 and 2; power supplies in slots PEM1 and PEM3 provide power to the upper fan tray, line-card slots 0 through 5, and switch fabric slot 0. There must be at least one power supply in each zone. Four power supplies provide full redundancy. If a power supply in a redundant configuration is removed or fails, its redundant power supply takes over without interruption. The power supply in

PEM2 serves as redundant power supply to the power supply in slot PEM0 and the power supply in PEM3 serves as redundant power supply to the power supply in slot PEM1. If only two power supplies

are installed, they must be installed in slots PEM0 and PEM1 or in slots PEM2 and PEM3. See “AC Power

Supply in an EX9214 Switch” on page 56.

DC power supplies—You can install four DC power supplies vertically at the rear of the chassis in slots

•

PEM0 through PEM3 (left to right). The power supplies operate in two zones: power supplies in slots PEM0 and PEM2 provide power to the lower fan tray, line-card slots 6 through 11, and switch fabric

slots 1 and 2; power supplies in slots PEM1 and PEM3 provide power to the upper fan tray, line-card slots 0 through 5, and switch fabric slot 0. There must be at least one power supply in each zone. Four power supplies provide full redundancy. If a power supply in a redundant configuration is removed or fails, its redundant power supply takes over without interruption. The power supply in PEM2 serves as redundant power supply to the power supply in slot PEM0 and the power supply in PEM3 serves as

redundant power supply to the power supply in slot PEM1. See “DC Power Supply in an EX9214 Switch”

on page 64.

Cooling system—The cooling system in an EX9214 switch consists of two fan trays and one air filter.

•

Each fan tray contains six fans. Under normal operating conditions, the fans in the fan trays 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 “EX9214 Cooling System” on page 53.

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 47 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 interface.

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 in an EX9200 Switch

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.

The cooling system components work together to keep all switch components within the acceptable temperature range. See Figure 15 on page 54 and Figure 16 on page 54.

Figure 15: Fan Tray Used in an EX9214 Switch

Figure 16: Air Filter Used in an EX9214 Switch

One of the fan trays is installed horizontally above the line card slots on the front panel and the other is installed horizontally above the air intake slot at the bottom of the front panel. The air filter is installed above the fan tray that is installed at the bottom of the front panel.

Airflow Direction in the EX9214 Switch Chassis

The air intake to cool the chassis is located on the front of the chassis, below the lower fan tray. Air is pulled through the chassis toward the fan tray, pushed up through the line card slots, and through the upper fan tray. See Figure 17 on page 55.

Figure 17: Airflow Through the EX9214 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 the 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 | 56

AC Power Supply Configurations | 58

An EX9214 switch is configurable with 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: EX9214 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 it is initially powered on determines the type of power supply the switch will operate with. 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 with one type of power supply, the switch disables the power supply you installed and generates an alarm.

This topic describes the AC power supplies in EX9214 switches.

AC Power Supply Description

The AC power supplies in EX9214 switches are hot-insertable and hot-removable field-replaceable units (FRUs).

You can install either two or four AC power supplies in an EX9214 switch. Power supplies are installed at the rear of the chassis in slots PEM0 through PEM3 (left to right). Four power supplies provide full redundancy.

WARNING: The switch is installed in a restricted-access location. It has a separate

g004710

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 11.9 lb (5.4 kg). The power supplies consist of an AC input switch and LEDs that indicate the status of the power supply. See Figure 18 on page 57.

Figure 18: AC Power Supply in an EX9214 Switch

EX9214 switches support 4100 W AC power supply. The AC power supply supports 200–240 VAC AC power configurations.

Each power supply has two power inlets: one located at the top of the power supply and another that requires a dedicated power feed, located directly above the power supply. We recommend that you use a customer site circuit breaker rated for 15.0 A @ 250 VAC circuit breaker minimum for each AC power supply, or one that complies with the local code. Doing so enables you to operate the switch in any configuration without upgrading the power infrastructure.

You can provide one or two feeds to the power supply. If you are using the power supply in one-feed mode, you must connect the power cord into the AC appliance inlet located on the chassis above the power supply. This is the recommended inlet when using the power supply in one-feed mode. If you are using the power supply in two-feed mode, you must connect another power cord to the AC appliance inlet on the power supply faceplate also.

AC Power Supply Configurations

EX9214 switches support two or four AC power supplies, installed vertically at the rear of the chassis in slots PEM0 through PEM3 (left to right), in two zones: power supplies in slots PEM0 and PEM2 provide power to the lower fan tray, line card slots 6 through 11, and SF slots 1 and 2; power supplies in slots PEM1 and PEM3 provide power to the upper fan tray, line card slots 0 through 5, and SF slot 0. There must be at least one power supply in each zone.

Four power supplies provide full redundancy. If a power supply in a redundant configuration is removed or fails, its redundant power supply takes over without interruption. The power supply in PEM2 serves as redundant power supply to the power supply in slot PEM0 and the power supply in PEM3 serves as redundant power supply to the power supply in slot PEM1. If only two power supplies are installed, they must be installed in slots PEM0 and PEM1 or in slots PEM2 and PEM3.

AC Power Cord Specifications for an EX9214 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 (2.5 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

Each power supply has two power inlets: one located at the top of the power supply and another that requires a dedicated power feed, located directly above the power supply. If you plan to operate a maximally configured DC-powered switch, we recommend that you use a dedicated customer site circuit breaker rated for 208 A (104 A per supply) (–40 VDC) minimum, or one that complies with the 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 –40 VDC.

DC Power Supply Configurations

EX9214 switches support four DC power supplies, installed vertically at the rear of the chassis in slots PEM0 through PEM3 (left to right), in two zones: power supplies in slots PEM0 and PEM2 provide power to the lower fan tray, line card slots 6 through 11, and SF slots 1 and 2; power supplies in slots PEM1 and PEM3 provide power to the upper fan tray, line card slots 0 through 5, and SF slot 0. There must be at least one power supply in each zone.

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.

Each host subsystem has LEDs in the craft interface that display its status. See “Craft Interface in an

EX9200 Switch” on page 44.

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 21 on page 73 and Figure 22 on page 74. 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, EX9208 Switch Configurations, and “EX9214 Switch Configurations” on page 28. 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.

•

The RE module boots from the storage media in the following order: the USB device (if present), then the SSD, and finally the LAN.

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.

NOTE: Starting with Junos OS Release 16.1, you can use EX9200 switches as an aggregation

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, or “EX9214 Switch Configurations” on page 28.

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

•

Routing Engine carrier

•

Figure 23 on page 78 shows the original SF module, EX9200-SF.

Figure 23: SF Module EX9200-SF

g022002

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 221.

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 225 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.

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.

The line card supports the following combinations of active PICs:
