END USER LICENSE AGREEMENT

READ THIS END USER LICENSE AGREEMENT (“AGREEMENT”) BEFORE DOWNLOADING, INSTALLING, OR USING THE SOFTWARE.

BY DOWNLOADING, INSTALLING, OR USING THE SOFTWARE OR OTHERWISE EXPRESSING YOUR AGREEMENT TO THE TERMS CONTAINED HEREIN, YOU (AS CUSTOMER OR IF YOU ARE NOT THE CUSTOMER, AS A REPRESENTATIVE/AGENT AUTHORIZED TO BIND THE CUSTOMER) CONSENT TO BE BOUND BY THIS AGREEMENT. IF YOU DO NOT OR CANNOT AGREE TO THE TERMS CONTAINED HEREIN, THEN (A) DO NOT DOWNLOAD, INSTALL, OR USE THE SOFTWARE, AND (B) YOU MAY CONTACT JUNIPER NETWORKS REGARDING LICENSE TERMS.

1. The Parties. The parties to this Agreement are (i) Juniper Networks, Inc. (if the Customer’s principal office is located in the Americas) or Juniper Networks (Cayman) Limited (if the Customer’s principal office is located outside the Americas) (such applicable entity being referred to herein as “Juniper”), and (ii) the person or organizationthat originally purchased from Juniper or an authorized Juniper reseller the applicable license(s) for use of the Software (“Customer”) (collectively, the “Parties”).

2. The Software. In this Agreement, “Software” means the program modules and features of the Juniper or Juniper-supplied software, for which Customer has paid the applicable license or support fees to Juniper or an authorized Juniper reseller, or which was embedded by Juniper in equipment which Customer purchased from Juniper or an authorized Juniper reseller. “Software” also includes updates, upgrades and new releases of such software. “Embedded Software” means Software which Juniper has embedded in or loaded onto the Juniper equipment and any updates, upgrades, additions or replacements which are subsequently embedded in or loaded onto the equipment.

3. License Grant. Subject to payment of the applicable fees and the limitations and restrictions set forth herein, Juniper grants to Customer a non-exclusive and non-transferable license, without right to sublicense, to use the Software, in executable form only, subject to the following use restrictions:

a. Customer shall use Embedded Software solely as embedded in, and for execution on, Juniper equipment originally purchased by Customer from Juniper or an authorized Juniper reseller.

b. Customer shall use the Software on a single hardware chassis having a single processing unit, or as many chassis or processing units for which Customer has paid the applicable license fees; provided, however, with respect to the Steel-Belted Radius or Odyssey Access Client software only, Customer shall use such Software on a single computer containing a single physical random access memory space and containing any number of processors. Use of the Steel-Belted Radius or IMS AAA software on multiple computers or virtual machines (e.g., Solaris zones) requires multiple licenses, regardless of whether such computers or virtualizations are physically contained on a single chassis.

c. Product purchase documents, paper or electronic user documentation, and/or the particular licenses purchased by Customer may specify limits to Customer’s use of the Software.Such limits may restrict use to a maximum number of seats, registeredendpoints, concurrent users, sessions, calls, connections, subscribers, clusters, nodes, realms, devices, links, ports or transactions, or require the purchase of separate licenses to use particular features, functionalities, services, applications, operations, or capabilities, or provide throughput, performance, configuration, bandwidth, interface, processing, temporal, or geographical limits. In addition, such limits may restrict the use of the Software to managing certain kinds of networks or require the Software to be used only in conjunction with other specific Software. Customer’s use of the Software shall be subject to all such limitations and purchase of all applicable licenses.

d. For any trial copy of the Software, Customer’s right to use the Software expires 30 days after download, installation or use of the Software. Customer may operate the Software after the 30-day trial period only if Customer pays for a license to do so. Customer may not extend or create an additional trial period by re-installing the Software after the 30-day trial period.

e. The Global Enterprise Edition of the Steel-Belted Radius software may be used by Customer only to manage access to Customer’s enterprise network. Specifically, service provider customers are expressly prohibited from using the Global Enterprise Edition of the Steel-Belted Radius software to support any commercial network access services.

The foregoing license is not transferable or assignable by Customer. No license is granted herein to any user who did not originally purchase the applicable license(s) for the Software from Juniper or an authorized Juniper reseller.

4. Use Prohibitions.

EX8208 Switch Hardware Overview

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, and power supplies.

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).

The Juniper Networks EX Series Ethernet Switches run under the Juniper Networks 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 J Series, M Series, MX Series, and T Series routers.

Complete Hardware Guide for EX8208 Ethernet Switches

Chassis Physical Specifications

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 4.

Figure 1: EX8208 Switch

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” on page 17.

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 9.

Routing Engines and Switch Fabric

Switchingfunctionality,systemmanagement, and system controlfunctions 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 24. An SRE module contains a Routing Engine and switch fabric. The SRE modules are installed in the front of the chassis in the slots labeled SRE0 and SRE1. See “Slot Numbering for an EX8208 Switch” on page 13. 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 6.

The Switch Fabric (SF) module, working with the SRE module, provides the necessary switchingfunctionality to a baseconfiguration 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 a redundant switch fabric. The additional switch fabric provides full 2+1 switch fabric redundancy to the switch. See “Switch Fabric (SF) Module in an EX8208 Switch” on page 28.

Line Cards

Chapter 1: EX8208 Switch Overview

Cooling System

The EX8208 switch features eight horizontal line card slots and supports the 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 field-replaceable units (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 13. All line cards are hot-removable and hot-insertable.

The following line cards are available for EX8208 switches:

•

8-port 10-Gigabit Ethernet SFP+ line card: This line card has eight 10-gigabit SFP+ ports on its faceplate in which you can install SFP+ transceivers. See “8-port SFP+ Line Card in an EX8200 Switch” on page 30.

•

40-port 10-Gigabit Ethernet SFP+ line card: Thisline card has 40 10-gigabit SFP+ ports on its faceplate in which you can install either SFP+ or SFP transceivers. See “40-port SFP+ Line Card in an EX8200 Switch” on page 31.

•

48-port 100/1000 SFP line card: This line card has 48 1-gigabit SFP ports on its faceplate in which you can install SFP transceivers. See “48-port SFP Line Card in an EX8200 Switch” on page 33.

•

48-port 10/100/1000 RJ-45 line card: This line card had 48 10/100/1000 Gigabit Ethernet ports with RJ-45 connectors on its faceplate. See “48-port RJ-45 Line Card in an EX8200 Switch” on page 34.

The cooling system in an EX8208 switch consists of a hot-removable and hot-insertable 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 “Cooling System and Airflow in an EX8208 Switch” on page 53.

Complete Hardware Guide for EX8208 Ethernet Switches

Power Supplies

Power supplies for the EX8208 switch are fully redundant, load-sharing, and hot-removable and hot-insertable field-replaceable units (FRUs). Each EX8208 switch chassis can hold up to six 2000 W AC, six 3000 W AC, or six 2000 W DC power supplies.

The 2000 W AC power supplies support both low-voltage line (100–120 VAC) and high-voltage line (200–240 VAC) AC power configurations on an EX8208 switch. Each 2000 W AC power supply delivers 2000 W of powerat high-voltageline (200–240 VAC) or 1200 W at low-voltage line (100–120 VAC) to the EX8208 chassis.

Each 3000 W AC power supply delivers 3000 W of power at high-voltageline (200–240 VAC) input to the EX8208 chassis. Low-voltage line input is not supported for the 3000 W AC power supplies on the EX8208 switch.

Each DC power supply delivers 2000 W of power to the chassis when the input voltage is in the range –40 VDC through –72 VDC.

Only two AC power supplies are required for the base AC configuration and switch powerup. 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 Supplyin an EX8200 Switch”on page40 and “EX8208 SwitchConfigurations”on page 6.

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 configurationalso provides sufficient capacity for N+1 redundancy in most configurations; if necessary,up to twoadditional DC supplies can be added to the system. See “DC Power Supplyin an EX8200 Switch”on page48 and “EX8208 Switch Configurations”on page 6.

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

Related Topics Rack Requirements for an EX8208 Switch on page 97•

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 handlesare provided on either side of the switch to facilitatethe 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.

Understanding EX8208 Switch Component and Functionality Redundancy

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 6.

This topic describes:

•

Hardware Components That Provide Redundancy on page 11

•

Routing Engine and Control Redundancy on page 12

•

Switch Fabric Redundancy on page 12

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 master and the other functions as the backup. If the master SRE module fails or is removed the backup module takes over as the master SRE module.

When the SRE modules are configuredfor gracefulswitchover, the backup SRE module automatically synchronizes its configuration and state with those of the master SRE module.Any update to the masterSRE module is replicated on the backup SRE module. If the backup module assumes mastership, 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 page55.) Each powersupply providespower to all the components in the switch.

An N+1 power configurationis requiredfor 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 40 and “DC PowerSupplyin an EX8200 Switch”on page 48.

•

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

Complete Hardware Guide for EX8208 Ethernet Switches

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 operateindefinitely and provides sufficient cooling even when a single fan fails provided the room temperature is within the operating range. See “Cooling System and Airflow in an EX8208 Switch” 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 master 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 3 on page 12 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.

Table 3: Routing Engine and Control Redundancy for EX8208 Switches

configuration

Switch Fabric Redundancy

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 installedand 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 4 on page 12 shows the available slots in an EX8208 chassis and the switch fabric redundancy associated with different SRE module and SF module combinations.

Switch Fabric (SF) Module in an EX8208 Switch

The Switch Fabric (SF) module provides switching functionality.See Figure 10 on page 28.

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 6.

Figure 10: 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 13.

Chapter 2: Component Descriptions

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 11.

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 11.

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 master. The master SRE module controls many internal functions of the SF module.

The SF module provides these functions:

•

Provideredundant 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 29.

•

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

•

The port groups can have different oversubscription ratios depending on the number of active ports in each port group. If only one port in a port group is active, the oversubscription ratio is 1:1. If two ports are active, the ratio is 2:1; if all ports are active, the ratio is 5:1.

If you transmit 10 gigabits of traffic through a port group, the line card does not drop packets. However, if you transmit more than 10 gigabits of traffic through a port group, the line card allows only a fair share of traffic to transit. For example, if you transmit 10 gigabits of traffic though each of the five ports in a port group, the line card allows only a fifth of the traffic from each port to transit. If you transmit 10 gigabits of traffic though twoports in a port group, the line card allowsonly half the traffic from each port to transit.

Because the port groups share bandwidth, class-of-service (CoS) ingress and egress queues are handled differently on the 40-port SFP+ line card than on other line cards for EX8200 switches (see Understanding CoS Queues on the 40-port SFP+ Line Card on EX8200 Switches). As a result, the ports in a port group must use the same scheduler map. By default, they use the default scheduler map. To configure a different scheduler map on the ports in a port group, see Defining CoS Schedulers (CLI Procedure).

AC Power Supply in an EX8200 Switch

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

•

AC Power Supply Description on page 40

•

N+1 Redundancy Configuration of AC Power Supplies on page 42

•

N+N Redundancy Configuration of AC Power Supplies on page 43

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 pluggable type A equipment installed in a restricted-access

location.It hasa separateprotectiveearthing terminal provided on the chassis in addition tothe grounding pin of the powersupply cord. This separate protective earthing terminal must be permanently connected to earth ground.

NOTE: All base configuration EX8200 switches are shipped with two power supplies. Coverpanels 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 6 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 its front. Each inlet requires a dedicated AC power feed. Each AC power supply has an Enable switch, a fan, and three LEDs on the faceplate that indicate the status of the power supply. See Figure 25 on page 41.

Chapter 2: Component Descriptions

Figure 25: AC Power Supply

Each AC power supply comes with a power retainer that holds the power cord in place. See Figure 26 on page 41. The power 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 retainer, see “Connecting AC Power to an EX8200 Switch” on page 173.

Figure 26: Power 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-voltageline (200–240 VAC)AC power configurations.In both cases,the output

Complete Hardware Guide for EX8208 Ethernet Switches

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 for high-voltage line input.

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 6 or EX8216 Switch Configurations.

The tables in this section list the N+1 power requirements for different EX8200 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 fail and the remaining N power supplies continue to supply power for 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 can depend on which Junos OS Release your switch is running:

Power Supplies Needed (N)Input Voltage

Power Supplies Needed for N+1

21High-voltage line

54High-voltage line

Complete Hardware Guide for EX8208 Ethernet Switches

•

Junos OS Release 10.1 or earlier—Consult Table 17 on page 42, Table 19 on page 43, or Table 20 on page 43 to determine the number of power supplies needed (N). Then multiple the N value 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 raisesan 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—Consult Table 21 on page 45, Table 23 on page 45, or Table 24 on page 46 in this section.

Starting with Junos OS Release 10.2, you can configure the powermanagement 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 extrapower that is held in reservein an N+N configurationthan in an N+1 configuration, becauseof which less powerwould ordinarilybe availableto powerline 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 powersupplies needed (N) forthe 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 6 or EX8216 Switch Configurations.

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 13 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 separateprotectiveearthing terminal must be permanently connected to earth ground.

NOTE: EX8216 switches have twoprotectiveearthing 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 6 for details about different EX8208 switch configurations.

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

Each DC power supply weighs approximately7 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 28 on page 49.

Chapter 2: Component Descriptions

Figure 28: 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 powerproduced 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 provideindependent A and B powerfeeds, so that dual power feed redundancy is available even in an N+1 configuration.

Cooling System and Airflow in an EX8208 Switch

The cooling system in an EX8208 switch consists of a single 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 30 on page 53.

Figure 30: Fan Tray for an EX8208 Switch

Chapter 2: Component Descriptions

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.

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 31 on page 54.

Complete Hardware Guide for EX8208 Ethernet Switches

Figure 31: 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 temperaturefrom the Environment Status option in the Status menu on the LCD panel. See “LCD Panel in an EX8200 Switch” on page 17.

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.

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.

Chapter 2: Component Descriptions

•

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,orany component connected to the backplane, with any metallic object while servicing components installed in the switch.
