Use this guide to install hardware and perform initial software configuration, routine maintenance, and troubleshootingfortheEX9208switch.Aftercompletingtheinstallationandbasicconfigurationprocedures covered in this guide, refer to the Junos OS documentation for information about further software configuration.

DocumentationandReleaseNotes

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/.

Iftheinformationinthelatestreleasenotesdiffersfromtheinformationinthedocumentation,followthe 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.

UsingtheExamplesinThisManual

If you want to use the examples in this manual, you can use the loadmerge or the loadmergerelative command. These commands cause the software to merge the incoming configuration into the current candidateconfiguration.Theexampledoesnotbecomeactiveuntilyoucommitthecandidateconfiguration.

xv

If the example configuration contains the top level of the hierarchy (or multiple hierarchies), the example is a fullexample. In this case, use the loadmerge command.

If the example configuration does not start at the top level of the hierarchy, the example is a snippet. In thiscase,usetheloadmergerelative command.Theseproceduresaredescribedinthefollowingsections.

MergingaFullExample

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 loadmerge configuration mode command:

[edit]

user@host# loadmerge/var/tmp/ex-script.conf load complete

xvi

MergingaSnippet

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.Movetothehierarchylevelthatisrelevantforthissnippetbyissuingthefollowingconfigurationmode command:

[edit]

user@host# editsystemscripts

[edit system scripts]

3.Merge the contents of the file into your routing platform configuration by issuing the loadmerge relative configuration mode command:

[edit system scripts]

user@host# loadmergerelative/var/tmp/ex-script-snippet.conf load complete

For more information about the load command, see CLI Explorer.

Juniper Networks EX9208 Ethernet Switches provide high performance, scalable connectivity, and carrier-classreliabilityforhigh-densityenvironmentssuchascampus-aggregationanddata-centernetworks. The EX9208 switch has a throughput of up to 4.8 terabits per second (Tbps) or up to 240 gigabits per second (Gbps) per slot full duplex. The EX9208 switch is a modular system that provides high availability and redundancy for all major hardware components, including Routing Engine modules (RE modules), Switch Fabric modules (SF modules), fan tray (redundant fans), and power supplies.

You can manage EX9208 switches by using the same interfaces that you use for managing other devices running the Juniper Networks Junos operating system (Junos OS)—the CLI, the Network and Security Manager (NSM), and Junos Space.

ChassisPhysicalSpecifications

The EX9208 switch is eight rack units (8 U) in size. Five EX9208 switches can fit in a standard 48 U rack. Each EX9208 switch is designed to optimize rack space and cabling. See Figure 1 on page 23,

Figure 2 on page 24, and Figure 3 on page 24.

CoolingSystem

The cooling system in an EX9208 switch is a field-replaceable unit (FRU). It consists of a hot-removable andhot-insertablefantray. Thefantraycontainssixfans. Thefantrayinstallsverticallyontherightback of the chassis and provides side-to-side chassis cooling. See “EX9208 Cooling System” on page 51.

PowerSupplies

Power supplies for the EX9208 switch are fully redundant, load-sharing, and hot-removable and hot-insertable FRUs. Each EX9208 switch chassis can hold up to four AC or DC power supplies.

Table 4 on page 26 shows the details of the power supplies available for EX9208 switches.

A base-configuration EX9208 switch ships with three low-line (100–120 VAC) or two high-line (200–240 VAC) AC power supplies. An AC-powered, redundant-configuration EX9208 switch ships with fourlow-line(100–120VAC)orfourhigh-line(200–240VAC)ACpowersupplies. See “ACPowerSupply in an EX9208 Switch” on page 53.

A DC-powered, redundant-configuration EX9208 switch ships with four DC power supplies. See “DC Power Supply in an EX9208 Switch” on page 60.

CAUTION: Do not mix AC and DC power supplies in the same chassis.
