Use this guide to install hardware and perform initial software configuration, routine maintenance, and troubleshootingfortheEX9204switch.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.

xiv

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

xv

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 EX9204 Ethernet Switches provide high performance, scalable connectivity, and carrier-classreliabilityforhigh-densityenvironmentssuchascampus-aggregationanddata-centernetworks. The EX9204 switch has a throughput of up to 1.6 terabits per second (Tbps) or up to 240 gigabits per second (Gbps) per slot full duplex.

You can manage EX9204 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.

BenefitsoftheEX9204Switch

Simplifiednetworkarchitecture—EX9204switchesdeliverasimple,secure,virtualizednetworkenvironment that increases business agility. They are ideal for simplifying campus, data center, and combined campus and data center network environments by collapsing network layers.

HostSubsystem

Switching and routing functionality, system management, and system control functions of an EX9204 switchareperformedbythehostsubsystem.ThehostsubsystemconsistsofaRoutingEnginefunctioning together with a Switch Fabric.

An EX9204 is a 4-slot chassis that provides two dedicated slots—labeled 1 and 2—for line cards, one dedicatedslot—labeled 0—forahostsubsystem,andonemultifunctionslot—labeled 1|0—foreitheraline card or a host subsystem.

You can install either one or two host subsystems in an EX9204 switch. A base-configuration EX9204 switch has one host subsystem. A redundant-configuration EX9204 switch has a second host subsystem. For more information, see “EX9204 Switch Configurations” on page 27.

LineCards

Line cards are field-replaceable units (FRUs) that you can install in the line card slots and in the multifunctionalslotonthefrontoftheswitchchassis. Alllinecardsarehot-removableandhot-insertable.

You can install up to three line cards in an EX9204 switch. Each EX9204 switch has two dedicated line card slots—labeled 1 and 2—and a multifunction slot—labeled 1|0—that you can use for either a line card or a host subsystem.

CoolingSystem

The cooling system in an EX9204 switch is a field-replaceable unit (FRU). It consists of a hot-removable and hot-insertable fan tray. The fan tray contains three fans. The fan tray installs vertically on the right back of the chassis and provides side-to-side chassis cooling. See “EX9204 Cooling System” on page 49.

PowerSupplies

Power supplies for the EX9204 switch are fully redundant, load-sharing, and hot-removable and hot-insertableFRUs. EachEX9204switchchassiscanholduptofourACoruptotwoDCpowersupplies.

Table 4 on page 26 shows the details of the power supplies available for EX9204 switches.

Table4:PowerSuppliesSupportedonEX9204Switches

Power Supply	Input Voltage	Output Power
2520 W AC	Low-voltage line (100–120 VAC)	1027 W
	High-voltage line (200–240 VAC)	1590 W
2400 W DC	–40 VDC through –70 VDC	2400 W to 2600 W

A base-configuration EX9204 switch ships with two low-line (100–120 VAC) AC power supplies or one high-line (200–240 VAC) AC power supply. An AC-powered, redundant-configuration EX9204 switch ships with four low-line (100–120 VAC) or two high-line (200–240 VAC) AC power supplies. See “AC Power Supply in an EX9204 Switch” on page 51.

A DC-powered, redundant-configuration EX9204 switch ships with two DC power supplies. See “DC Power Supply in an EX9204 Switch” on page 59.

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