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]

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 EX8208 Ethernet Switches provide high performance, scalable connectivity, and carrier-class reliability for high-density environments such as campus-aggregation and data-center networks. The EX8208 switch is a modular system that provides high availability and redundancy for all major hardware components, including Routing Engines, switch fabric, fan tray (redundant fans), and power supplies.

You can form an EX8200 Virtual Chassis by connecting individual EX8200 switches to an XRE200 External Routing Engine. A Virtual Chassis is multiple switches connected together that operate as a single network entity.

You can manage EX8208 switches using the same interfaces that you use for managing other devices running the Juniper Networks Junos operating system (Junos OS)—the command-line interface (CLI), the J-Web graphical interface, and the Network and Security Manager (NSM).

Benefits of the EX8208 Switch

Support for Virtual Chassis—EX8208 switches support Virtual Chassis technology. You can configure EX8200 switches in a Virtual Chassis and manage and operate them as a single network entity by using the XRE200 External Routing Engine.

High capacity—With a total capacity of up to 6.2 Terabits per second (Tbps), EX8208 is a powerful modular platform that delivers the performance, scalability, and high availability required for high-density data center, campus aggregation, and core switching environments.

Support for Juniper Networks Service Now solution—EX8200 switches support the Juniper Networks Service Now solution, a comprehensive set of tools that enable Juniper Networks J-Care Technical Service offerings to automate the delivery of tailored, proactive network intelligence and support services.

Software

The Juniper Networks EX Series Ethernet Switches run Junos OS, which provides Layer 2 and Layer 3 switching, routing, and security services. The same Junos OS code base that runs on EX Series switches also runs on all Juniper Networks M Series, MX Series, and T Series routers and SRX Series Services Gateways.

Chassis Physical Specifications, LCD Panel, and Backplane

The EX8208 switch is 14 rack units (14 U) in size (1/3 rack). Three EX8208 switches can fit in a standard 42 U rack. Each EX8208 switch is designed to optimize rack space and cabling. See Figure 1 on page 23.

panel

The EX8208 switch has a chassis-level LCD panel that displays Routing Engine and switch fabric status as well as chassis components’ alarm information for rapid problem identification. The LCD panel provides a user-friendly interface for performing initial switch configuration, rolling back a configuration, or restoring the switch to its default settings. See LCD Panel in an EX8200 Switch.

The EX8208 chassis backplane distributes the data, control, and management signals to various system components along with distributing power throughout the system.

See “Chassis Physical Specifications of an EX8208 Switch” on page 33.

Routing Engines and Switch Fabric

Switching functionality, system management, and system control functions of an EX8208 switch are performed by a Switch Fabric and Routing Engine (SRE) module. See “Switch Fabric and Routing Engine

(SRE) Module in an EX8208 Switch” on page 78. An SRE module contains a Routing Engine and switch

fabric. The SRE modules are field-replaceable units (FRUs) that are installed in the front of the chassis in

the slots labeled SRE0 and SRE1. See “Slot Numbering for an EX8208 Switch” on page 40. A base configuration EX8208 switch has one SRE module. A redundant configuration EX8208 switch has a second SRE module. See “EX8208 Switch Configurations” on page 27.

The Switch Fabric (SF) module, working with the SRE module, provides the necessary switching functionality to a base configuration EX8208 switch. The SF module is installed in the front of the chassis in the slot labeled SF. In a redundant configuration, the SF module provides full 2+1 switch fabric redundancy to the switch. See “Switch Fabric (SF) Module in an EX8208 Switch” on page 81.

The EX8208 switch can also be connected to an XRE200 External Routing Engine. An XRE200 External Routing Engine is used to connect multiple EX8200 switches into a Virtual Chassis. See XRE200 External Routing Engine Hardware Overview.

Line Cards

The EX8208 switch features eight horizontal line card slots and supports line rate for each line card. The line cards in EX8200 switches combine a Packet Forwarding Engine and Ethernet interfaces on a single assembly. Line cards are FRUs that can be installed in the line card slots labeled 0 through 7 on the front of the switch chassis. See “Slot Numbering for an EX8208 Switch” on page 40. All line cards are hot-removable and hot-insertable.

Twelve line cards are available for EX8200 switches. The extra-scale line card models provide larger IPv4 and IPv6 route table sizes than the non-extra-scale models to store more unicast routes.

Table 3 on page 24 shows the model numbers and descriptions of the line cards available for EX8200

switches.

NOTE: We recommend that you do not install extra-scale line card models and non-extra-scale

models in the same switch or Virtual Chassis. If you install extra-scale line cards in a switch or Virtual Chassis that has non-extra-scale models installed, the IPv4 and IPv6 route table sizes default to those of the non-extra-scale models and you will not get the benefit of the increased table sizes of the extra-scale models.

You will experience these decreased route table sizes in a Virtual Chassis even when the non-extra-scale line cards are installed in one member switch and the extra-scale line cards are installed in another member switch.

Cooling System

The cooling system in an EX8208 switch consists of a hot-removable and hot-insertable FRU fan tray. The fan tray contains 12 fans. The fan tray installs vertically on the left front of the chassis and provides side-to-side chassis cooling. See “EX8208 Cooling System” on page 53.

Power Supplies

Power supplies for the EX8208 switch are fully redundant, load-sharing, and hot-removable and hot-insertable (FRUs. Each EX8208 switch chassis can hold up to six AC or DC power supplies.

Table 4 on page 26 shows the details of the power supplies available for EX8208 switches.

Only two AC power supplies (provided) are required to power on the base AC configuration switch. The redundant AC configuration ships with six AC power supplies to provide the capacity to power the system using N+1 or N+N power redundancy. See “AC Power Supply in an EX8200 Switch” on page 56 and

“EX8208 Switch Configurations” on page 27.

The redundant DC configuration ships with four DC power supplies. The dual inputs of the DC supplies provide direct support for N+N power redundancy. The redundant configuration also provides sufficient capacity for N+1 redundancy in most configurations; if necessary, up to two additional DC supplies can be added to the system. See “DC Power Supply in an EX8200 Switch” on page 70 and “EX8208 Switch

Configurations” on page 27.

CAUTION: Mixing different types of power supplies (AC and DC) in the same chassis

is not supported.

You can mount an EX8200 switch on a standard 19-in. four-post rack or a standard 800-mm enclosed cabinet. Up to three EX8208 switches can be installed in a standard (42 rack unit (U)) rack provided the rack can handle their combined weight.

Lift handles are provided on either side of the switch to facilitate the handling of a chassis with only the backplane installed.

WARNING: Do not use the lift handles to lift the chassis unless the chassis is empty

(that is, contains only the backplane). Failure to heed this warning can result in injury. See “Mounting an EX8208 Switch on a Rack or Cabinet Using a Mechanical Lift” on

page 157 or “Mounting an EX8208 Switch on a Rack or Cabinet Without Using a Mechanical Lift” on page 159 for instructions for moving a loaded chassis.

Field-Replaceable Units in an EX8208 Switch

Field-replaceable units (FRUs) are switch components that you can replace at your site. The switch uses these 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 35 lists the FRUs for the EX8208 switch and their types.

Hardware Components That Provide Redundancy | 37

Routing Engine and Control Redundancy | 38

Switch Fabric Redundancy | 39

The Juniper Networks EX8208 Ethernet Switch is available as a fully redundant system. A redundant EX8208 switch configuration is designed so that no single point of failure can cause the entire switch to fail. See “EX8208 Switch Configurations” on page 27.

Hardware Components That Provide Redundancy

The following hardware components provide redundancy to an EX8208 switch:

SRE modules—An EX8208 switch can have either one Switch Fabric and Routing Engine (SRE) module

•

or two SRE modules. If two SRE modules are installed, one SRE module functions as the primary and the other functions as the backup. If the primary SRE module fails or is removed the backup module takes over as the primary SRE module.

When the SRE modules are configured for graceful switchover, the backup SRE module automatically synchronizes its configuration and state with those of the primary SRE module. Any update to the primary SRE module is replicated on the backup SRE module. If the backup module assumes primary role, packet forwarding continues through the switch.

Power supplies—You can install up to six AC or six DC power supplies in an EX8208 switch. Each power

•

supply connects to the backplane of the chassis, which distributes the output power produced by the power supplies to different switch components. (See “Backplane in an EX8208 Switch” on page 49.) Each power supply provides power to all the components in the switch.

An N+1 power configuration is required for Juniper Networks EX8200 Ethernet Switches. In an N+1 power configuration, if one power supply fails or is removed, the remaining power supplies continue to supply power for the entire system without interruption. If dual power feed redundancy is required, the required power configuration is N+N. The DC power supplies provide independent A and B power feeds so that dual power redundancy is available even in an N+1 power configuration. See “AC Power Supply

in an EX8200 Switch” on page 56 and “DC Power Supply in an EX8200 Switch” on page 70.

Cooling system—The cooling system in an EX8200 switch consists of a single fan tray. The fan tray

•

contains 12 fans. Under normal operating conditions, the fans in the fan tray run at less than full speed.

The fans are controlled by two fan tray controllers. The fans are numbered 1 through 12. Fans 1 through 6 are controlled by the first fan tray controller. Fans 7 through 12 are controlled by the second fan tray controller. If one fan tray controller fails, the other fan tray controller keeps half the fans working. This allows the switch to continue to operate normally as long as the remaining fans cool the chassis sufficiently.

The fan tray continues to operate indefinitely and provides sufficient cooling even when a single fan fails provided the room temperature is within the operating range. See “EX8208 Cooling System” on

page 53.

Routing Engine and Control Redundancy

Each SRE module contains switch fabric circuitry, Routing Engine circuitry, and switch control and management circuitry. An EX8208 switch can have one SRE module or two SRE modules. If a switch has two SRE modules, one functions as the primary while the other functions as a backup and is in standby mode. This provides the switch with full redundancy (1+1) for Routing Engine and switch control functionality.

Table 9 on page 39 shows the available slots in the EX8208 chassis and the Routing Engine and control

redundancy associated with different SRE module and Switch Fabric (SF) module combinations.

The switch fabric circuitry in an EX8208 switch is distributed across three modules—two SRE modules and one SF module. Any two of these three modules must be installed and functional to provide a working switch fabric with no redundancy. The third module, when present, provides partial redundancy (2+1) for the switching functionality, such that if any one of the two functional modules becomes nonoperational, the third module takes over.

Table 10 on page 39 shows the available slots in an EX8208 chassis and the switch fabric redundancy

associated with different SRE module and SF module combinations.

Slots 0 through 7 accept one of the line cards available. See “Installing a Line Card in an EX8200 Switch”

on page 271.

Slots SRE0 and SRE1 accept only the SRE module. You can install one SRE module or two SRE modules based on the configuration of your switch. See “Switch Fabric and Routing Engine (SRE) Module in an

EX8208 Switch” on page 78.

NOTE: We recommend that you install two SRE modules for redundancy. If you install only one

SRE module, we recommend that you install it in the slot SRE0. See “Installing an SRE Module

in an EX8208 Switch” on page 255.

Slot SF accepts only the SF module. See “Switch Fabric (SF) Module in an EX8208 Switch” on page 81. An EX8208 switch can have either zero SF modules or one SF module based on your switch configuration. The SF module is keyed so that it does not fit in any other slot in the chassis. See “Installing an SF Module

in an EX8208 Switch” on page 259.

Slot Numbering for the Power Supply Slots

The chassis has six vertical slots on its front bottom. You can install up to six power supplies (either all AC or all DC) in these slots, which are labeled PSU 0 through PSU 5 (from left to right). Table 12 on page 42 lists the slot numbers for the power supplies on an EX8208 switch. See “AC Power Supply in an EX8200

Switch” on page 56 and “DC Power Supply in an EX8200 Switch” on page 70.

CAUTION: Mixing different types of power supplies in the same chassis is not a

The LCD panel on the top front of the EX8200 switch chassis shows two lines of text with a maximum of 16 characters in each line. The LCD panel displays a variety of information about the switch and provides menu options to perform basic operations such as initial configuration and switch reboot.

There are two navigation buttons—Menu and Enter—to the right of the LCD panel.

See Figure 5 on page 43.

Figure 5: LCD Panel in an EX8200 Switch

You can configure the second line of the LCD panel to display a custom message. If the LCD panel is configured to display a custom message, the Menu button and the Enter button are disabled. See

“Configuring the LCD Panel on EX Series Switches (CLI Procedure)” on page 202.

The LCD panel has a backlight. If the LCD panel is idle for 60 seconds, the backlight turns off. You can turn on the backlight by pressing the Menu or Enter button once. After turning on the backlight, you can toggle between the LCD menus by pressing the Menu button and navigate through the menu options by pressing the Enter button.

NOTE: The chassis viewer in the J-Web interface also displays the LCD panel. From the J-Web

interface, you can view real-time status information in the LCD panel. See “Dashboard for EX

Series Switches” on page 205.

LCD Panel Modes

The LCD panel operates in four modes: boot, idle, status, and maintenance.

The LCD panel operates in boot mode during switch reboot.

The boot mode displays the key milestones in the switch boot process. The boot mode does not have any menu options. After the boot process is complete, the LCD panel automatically reverts to the Idle menu.

In the idle mode, line two of the Idle menu displays the Status LED modes of the network ports and the total number of alarms in the system. The number of alarms is updated every second.

The status mode allows you to get status information for the following items:

Backplane in an EX8208 Switch

The backplane is a printed circuit board that forms the back of the line card cage. The Switch Fabric and Routing Engine (SRE) modules, Switch Fabric (SF) module, power supplies, and line cards plug into the backplane from the front of the chassis. The backplane contains an EEPROM that stores the serial number and revision level of the backplane.

The backplane performs the following functions:

Power distribution—The backplane distributes power to all the switch components from the power

•

supplies that plug into it.

Control-signal connectivity—The backplane transports the control signals exchanged by system

•

components for monitoring, control, and management purposes.

Transfer of data between line cards and SRE modules—The backplane provides connectivity for data

•

traffic to and from the line cards and the SRE modules.

WARNING: High levels of electrical energy are distributed across the switch backplane.

Do not touch the backplane connectors, or any component connected to the backplane, with any metallic object while servicing components installed in the switch.

Chassis Status LEDs in an EX8200 Switch

The top front of the chassis of an EX8200 switch has three LEDs on the right side of the LCD panel.

See Figure 6 on page 50.

Fan Tray | 54

Airflow Direction in the EX8208 Switch Chassis | 55

The cooling system in an EX8208 switch consists of a single fan tray.

Fan Tray

The fan tray is a hot-insertable and hot-removable field-replaceable unit (FRU). The fan tray contains 12 fans.

The fan tray installs vertically on the left side on the front of the chassis and provides side-to-side chassis cooling. A handle on the front faceplate facilitates handling of the fan tray. See Figure 8 on page 54.

Figure 8: Fan Tray for an EX8208 Switch

The fan tray can be removed and replaced from the front of the chassis. The switch continues to operate for a limited time (2 minutes) during the replacement of the fan tray without thermal shutdown.

CAUTION: You must replace the fan tray within 2 minutes of removing it.

Airflow Direction in the EX8208 Switch Chassis

The air intake to cool the chassis is located on the right side of the chassis. Air is pulled into the chassis and is pushed thorough the line card cage towards the fan tray. Hot air exhausts from the left side of the chassis. See Figure 9 on page 55.

Figure 9: Airflow Through the EX8208 Switch Chassis

The Switch Fabric and Routing Engine (SRE) module monitors the temperature of switch components. Under normal operating conditions, the fans in the fan tray run at less than full speed. The fans are controlled by two fan tray controllers. The fans are numbered 1 through 12. Fans 1 through 6 are controlled by the first fan tray controller. Fans 7 through 12 are controlled by the second fan tray controller. If one fan tray controller fails, the other fan tray controller keeps half the fans working. This allows the switch to continue to operate normally as long as the remaining fans cool the chassis sufficiently.

If a fan fails or the ambient temperature rises above the threshold 113°F (45°C), the speed of the remaining fans is automatically adjusted to keep the temperature within the acceptable range, 32°F (0°C) through 104°F (40°C).

The fan tray continues to operate indefinitely and provide sufficient cooling even when a single fan fails provided the room temperature is within the operating range. You can check the status of fans and the chassis temperature from the Environment Status option in the Status menu on the LCD panel. See LCD Panel in an EX8200 Switch.

You cannot replace a single fan. If one or more fans fail, you must replace the entire fan tray.

WARNING: There is no fan guard on the fans. Be careful to keep your fingers clear

of moving fan blades when you are removing the fan tray.

EX8200 switches can use either AC or DC power supplies. This topic describes the AC power supplies in EX8200 switches.

AC Power Supply Description

The AC power supplies in EX8200 switches are hot-insertable and hot-removable field-replaceable units (FRUs).

You can install up to six AC power supplies in an EX8200 switch. Power supplies are installed at the bottom of the chassis in slots PSU 0 through PSU 5 (left to right). All power supplies are accessible from the front of the chassis.

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

protective earthing terminal on the chassis that must be permanently connected to earth ground to adequately ground the chassis and protect the operator from electrical hazards.

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.

NOTE: All base configuration EX8200 switches are shipped with two power supplies. Cover

panels are installed over the remaining four power supply slots. Additional power supplies can be added to base configuration switches as necessary.

For details about different switch configurations, see “EX8208 Switch Configurations” on page 27 or EX8216 Switch Configurations.

Each AC power supply weighs approximately 7 lb (3.2 kg) and has an independent 16 A rated AC inlet on the faceplate. Each inlet requires a dedicated AC power feed. Each AC power supply has a switch labeled ENABLE, a fan, and three LEDs on the faceplate that indicate the status of the power supply. See

Figure 10 on page 58.

Figure 10: AC Power Supply

Each AC power supply comes with a power cord retainer that holds the power cord in place. See

Figure 11 on page 58. The power cord retainer has a clip and an adjustment nut. The L-shaped ends of

the clip hook into the bracket holes on each side of the AC appliance inlet on the faceplate. The adjustment nut holds the power cord in the correct position. For instructions for installing the power cord retainer, see “Connecting AC Power to an EX8200 Switch” on page 171.

Figure 11: Power Cord Retainer for an AC Power Supply

Each power supply connects to the backplane in an EX8208 switch and to the midplane in an EX8216 switch. The backplane and the midplane distribute the output power produced by the power supplies to different switch components. Each AC power supply provides power to all the components in the switch.

Each power supply has its own fan and is cooled by its own internal cooling system. The airflow is from the front of the power supply to the back. Hot air exhausts from the rear of the chassis.

EX8200 switches support both 2000 W AC power supplies and 3000 W AC power supplies.

The 2000 W AC power supply supports both the low-voltage line (100–120 VAC) and the high-voltage line (200–240 VAC) AC power configurations. In both cases, the output is 52 VDC. The output power is 1200 W for low-voltage line input and 2000 W for high-voltage line input.

The 3000 W AC power supply supports only the high-voltage line input (200–240 VAC) AC power configuration. Low-voltage line input is not supported for the 3000 W AC power supplies on the EX8200 switches. The output is 52 VDC. The output power is 3000 W.

N+1 Redundancy Configuration of AC Power Supplies

N+1 redundancy configuration is required for normal operation of EX8200 switches. In an N+1 redundancy configuration, if one power supply fails or is removed, the remaining power supplies continue to supply power for the switch without interruption.

Depending on the configuration type of the switch and the input voltage, determine the number of power supplies needed (N) for a switch. Install an additional power supply to meet the required N+1 redundancy configuration. For details about different switch configurations, see “EX8208 Switch Configurations” on

page 27 or EX8216 Switch Configurations.

N+N Redundancy Configuration of AC Power Supplies

You can optionally configure your switch for N+N redundancy, in which N power supplies can be removed or can fail and the remaining N power supplies continue to supply power to the switch without interruption. A common application for N+N redundancy is to have a dual power feed for AC power supplies.

How many power supplies you require for N+N redundancy depends on which Junos OS release your switch is running:

Junos OS Release 10.1 or earlier—Use Table 17 on page 59, Table 18 on page 60, Table 19 on page 60,

•

or Table 20 on page 60 to determine the number of power supplies needed (N). Then multiply the value of N by two.

NOTE: In Junos OS Release 10.1 or earlier, the power management feature manages switches

for N +1 redundancy only. This means, for example, that power management raises an alarm if there is insufficient power to maintain N +1 redundancy, but not if there is insufficient power to maintain N+N redundancy.

Junos OS Release 10.2 or later—Use Table 21 on page 62, Table 22 on page 62, Table 23 on page 62,

•

or Table 24 on page 63 in this section.

Starting with Junos OS Release 10.2, you can configure the power management software to manage the switch power for N+N redundancy. When you configure power management for N+N redundancy, power management lowers the maximum chassis power consumption by lowering the maximum fan speed. It does so to compensate for the extra power that is held in reserve in an N+N configuration than in an N+1 configuration, because of which less power would ordinarily be available to power line cards. By reducing the maximum chassis power consumption, power management allows the switch to power more line cards.

The configuration type of the switch and the input voltage determine the number of power supplies needed (N) for the switch. You must then install additional power supplies to meet the N+N redundancy configuration. For details about different switch configurations, see “EX8208 Switch Configurations” on

page 27 or EX8216 Switch Configurations.

AC Power Cord Specifications for an EX8200 Switch

Each AC power supply has a single AC appliance inlet 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.

Each detachable AC power cord is 8 feet (approximately 2.5 meters) long. The appliance coupler end of the cord inserts into the AC appliance inlet on the faceplate of the AC power supply. The coupler type is C19 as described by the International Electrotechnical Commission (IEC) standard 60320. The plug end of the power cord fits into the power source outlet that is standard for your geographical location.

NOTE: In North America, AC power cords must not exceed 15 feet (approximately 4.5 meters)

in length, to comply with National Electrical Code (NEC) Sections 400-8 (NFPA 75, 5-2.2) and 210-52 and Canadian Electrical Code (CEC) Section 4-010(3). The cords shipped with the switch to North America and Canada are in compliance.

Table 28 on page 67 lists the AC power cord specifications for an EX8200 switch for various countries

and regions.

CAUTION: AC power cords for EX8200 switches are intended for use with these

switches only. Do not use the cord for another product.

Power Cable Warning (Japanese)

WARNING: The attached power cable is only for this product. Do not use the cable for another product.

CAUTION: Power cords must not block access to switch components. We recommend

that you route all AC power cord cables through the power cord tray provided with the switch.

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

protective earthing terminal on the chassis that must be permanently connected to earth ground to adequately ground the chassis and protect the operator from electrical hazards.

DC Power Supply in an EX8200 Switch

The DC power supplies in EX8200 switches are hot-removable and hot-insertable field-replaceable units (FRUs).

NOTE: EX8208 switches support 2000 W DC power supplies.

EX8216 switches support 3000 W DC power supplies.

You can install up to six DC power supplies in an EX8200 switch. Power supplies are installed at the bottom of the chassis in slots labeled PSU 0 through PSU 5 (left to right). See “Slot Numbering for an EX8208

Switch” on page 40 and Slot Numbering for an EX8216 Switch. All power supplies are accessible from the

front of the chassis.

WARNING: The switch is pluggable type A equipment installed in a restricted-access

location. It has a separate protective earthing terminal provided on the chassis. This separate protective earthing terminal must be permanently connected to earth ground.

NOTE: EX8216 switches have two protective earthing terminals provided on the chassis, one

on the left side of the chassis and the other on the rear of the chassis. Only one of these protective earthing terminals needs to be permanently connected to earth ground. See Chassis Physical Specifications of an EX8216 Switch for the location of the protective earthing terminals.

NOTE: DC power supplies are shipped only in the redundant configuration of EX8200 switches.

See “EX8208 Switch Configurations” on page 27 for details about different EX8208 switch configurations.

See EX8216 Switch Configurations for details about different EX8216 switch configurations.

Each DC power supply weighs approximately 7 lb (3.2 kg) and has two independent pairs of DC input lugs (A: –48V A: RTN and B: – 48V B: RTN ) on the front of the power supply. Each power supply also has an Enable switch, a fan, and four LEDs on the faceplate that indicate the status of the power supply. See

Figure 13 on page 71.

Figure 13: DC Power Supply

NOTE: A 2000 W DC power supply requires a dedicated 60 A circuit breaker for each input DC

feed.

A 3000 W DC power supply requires a dedicated 100 A circuit breaker for each input DC feed.

Each DC power supply connects to the backplane in an EX8208 switch and to the midplane in an EX8216 switch. The backplane in an EX8208 switch and the midplane in an EX8216 switch distribute the output power produced by the power supplies to different switch components. Each DC power supply provides power to all the components in the switch.

The output of each 2000 W DC power supply is 52 VDC. The output power is 2000 W.

The output of each 3000 W DC power supply is 52 VDC. The output power is 3000 W.

A DC power supply works with only one input DC feed connected. It is able to deliver the full output power to all chassis components with only one DC feed connected.

Each DC power supply has its own fan and is cooled by its own internal cooling system. The airflow is from the front of the power supply to the back. Hot air exhausts from the rear of the chassis.

The minimum power configuration required by an EX8200 switch is an N+1 power configuration. In an N+1 power configuration, if one power supply fails or is removed, the remaining power supplies continue to supply power for the system without interruption.

The configuration type of the switch and the input voltage determine the number of power supplies needed (N) for a switch. You must install an additional power supply to meet the required N+1 power redundancy configuration. The DC power supplies each provide independent A and B power feeds, so that dual power feed redundancy is available even in an N+1 configuration. See “EX8208 Switch Configurations” on page 27 for details about different EX8208 switch configurations. See EX8216 Switch Configurations for details about different EX8216 switch configurations.

Grounding Cable and Lug Specifications for EX8200 Switches

To ensure proper operation and to meet safety and electromagnetic interference (EMI) requirements, you must connect an EX Series switch to earth ground before you connect power to the switch. You must use the protective earthing terminal on the switch chassis to connect the switch to earth ground.

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

protective earthing terminal on the chassis that must be permanently connected to earth ground to adequately ground the chassis and protect the operator from electrical hazards.

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.

Switch Fabric and Routing Engine (SRE) Module in an EX8208 Switch

The Switch Fabric and Routing Engine (SRE) module performs switching and system management functions in an EX8208 switch. See Figure 16 on page 78.

You can install one or two SRE modules in an EX8208 switch. A base configuration EX8208 switch has only one SRE module. See “EX8208 Switch Configurations” on page 27. You can add a second SRE module to the configuration for Routing Engine and switch control redundancy. See “Understanding EX8208 Switch

Component and Functionality Redundancy” on page 37.

The SRE modules install horizontally into the front of the chassis in slots labeled SRE0 and SRE1.

Figure 16: SRE Module in an EX8208 Switch

NOTE: We recommend that you install two SRE modules for redundancy. If you install only one

SRE module, we recommend that you install it in slot SRE0. See “Slot Numbering for an EX8208

Switch” on page 40.

If two SRE modules are installed, one functions as the primary and the other acts as the backup. If the primary SRE module fails or is removed, the backup takes over as the primary.

If two SRE modules are installed, the backup SRE module is hot-insertable and hot-removable, but the primary SRE module is hot-pluggable. If only one SRE module is installed, you must halt the SRE module before removing it.

The SRE module provides these functions:

Provides full fabric connectivity to all line cards installed in the chassis

•

Through the switching plane, provides switching functionality to the switch

•

Powers the line cards on and off

•

Controls system resets and boot sequence for the switch

•

Monitors and controls the fan speed, power status for various chassis components, LCD panel and

•

chassis status LEDs

The SRE module has these components:

SRE module LEDs—Indicate system status. See “SRE Module LEDs in an EX8208 Switch” on page 80.

•

Recessed reset button—Power cycles the SRE module when pressed.

•

Take the SRE module offline using the CLI before pressing the reset button. See “Taking the SRE Module

Offline in an EX8208 Switch” on page 251.

USB port—Provides an interface through which you can install the Junos OS manually. See “USB Port

•

Specifications for an EX Series Switch” on page 136.

Auxiliary port—This port is not enabled on the EX8200 switch. It is reserved for future use.

•

Console port—Connects the SRE module to a system console through a cable with an RJ-45 connector.

•

See “Connect a Device to a Management Console Using an RJ-45 Connector” on page 183.

Management port—Connects the SRE module through an Ethernet connection to a management LAN

Switch Fabric (SF) Module in an EX8208 Switch

The Switch Fabric (SF) module provides switching functionality. See Figure 18 on page 81.

An EX8208 switch can have either zero SF modules or one SF module. The base configuration of an EX8208 switch includes one SF module. See “EX8208 Switch Configurations” on page 27.

Figure 18: SF Module in an EX8208 Switch

The SF module can be installed only in the slot labeled SF. The SF module is keyed so that it does not fit in the other slots in the chassis. See “Slot Numbering for an EX8208 Switch” on page 40.

In the base configuration, an SF module is used with a single Switch Fabric and Routing Engine (SRE) module to build a nonredundant system that provides full bandwidth. However, a base configuration EX8208 switch has no Routing Engine and switch control redundancy or switch fabric redundancy. In a base configuration, the main function of the SF module is to switch data between line cards. See

“Understanding EX8208 Switch Component and Functionality Redundancy” on page 37.

In a redundant configuration, an SF module is used with two SRE modules to achieve full bandwidth along with Routing Engine and switch control redundancy and switch fabric redundancy. In a redundant

configuration, the main function of the SF module is to provide a redundant switching plane for the switch. See “Understanding EX8208 Switch Component and Functionality Redundancy” on page 37.

In a redundant configuration, the SF module is hot-pluggable. However, in the base configuration, you must take the SF module offline before removing it.

The SF module contains logic that determines which SRE module is the primary. The primary SRE module controls many internal functions of the SF module.

The SF module provides these functions:

Provide redundant data path connectivity for the switch in the redundant configuration

•

Provide nonredundant data path connectivity for the switch in the base configuration

•

The SF module has these components:

SF module LEDs—Indicate system status. See “SF Module LEDs in an EX8208 Switch” on page 82.

•

Ejector levers—Used for installing and removing the SF module.

•

Captive screws—Secure the SF module in place.

IN THIS SECTION

Line Card Models | 87

Line Card Components | 87

The line cards in EX8200 switches combine a Packet Forwarding Engine and Ethernet interfaces on a single assembly. They are field-replaceable units (FRUs) that can be installed in the line card slots on the front of the switch chassis. The line cards are hot-insertable and hot-removable: You can remove and replace them without powering off the switch or disrupting switch functions (see Figure 20 on page 86).

Figure 20: 8-port SFP+ Line Card

NOTE: Figure 20 on page 86 shows a line card that has 2-in.-long ejector levers. An earlier

version of this line card has 4-in.-long ejector levers.

NOTE: The 10-Gigabit Ethernet ports on the 8-port SFP+ line cards are the only ports that

you can configure as Virtual Chassis port (VCP) links between EX8200 member switches in an EX8200 Virtual Chassis. You cannot configure ports on any other EX8200 line cards—including the 10-Gigabit Ethernet ports on the 40-port SFP+ line cards—as VCPs. See Setting a 10-Gigabit Ethernet Port as a Virtual Chassis Port in an EX8200 Virtual Chassis (CLI Procedure).

Figure 22: Port Numbering and Port Groups on a 40-port SFP+ Line Card

The ports in each port group share 10 gigabits of bandwidth. Thus, you can transmit up to 10 gigabits of traffic through a port group without packet drop.

The oversubscription ratios for different port groups can differ from one another; the ratios depend on the amount of traffic being transmitted through a port group.
