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.

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

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]

[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.

SRX4200ServicesGatewayOverview

The Juniper Networks SRX4200 Services Gateway is a high-performance, scalable mid-range services gateway,whichconsolidatessecurity,next-generationfirewall,andadvancedthreatpreventioncapabilities toprovidesecureconnectivity. Theservicesgatewaysupports40GbpsIMIXthroughputandissuitedfor small to medium enterprises and data centers.

The SRX4200 Services Gateway supports advanced threat prevention through Sky Advanced Threat Prevention (Sky ATP) and Spotlight Secure Threat Intelligence, in addition to key features such as VPN, IPS, and UTM.

The chassis is 1 U high and is designed for rack installation. The services gateway is shipped with dual power supplies and is available in both AC-powered and DC-powered versions:

•SRX4200 (AC) — SRX4200 Services Gateway with dual AC power supplies

•SRX4200 (DC) — SRX4200 Services Gateway with dual DC power supplies

The SRX4200 Services Gateway comes with 64 GB of DDR4 memory and two 240-GB solid-state drives (SSDs) in a redundant array of independent disks (RAID). Both disks are configured as a RAID-1 mirror (data is concurrently written to both SSDs). If one SSD becomes inoperable, the other SSD continues to be active.

The services gateway runs the Junos OS and can be managed using the CLI, Junos Space, and J-Web.

SRX4200ServicesGatewayChassisOverview

The 4200 Services Gateway chassis is a rigid sheet metal structure that houses all the other hardware components. The chassis measures 1.75 in. high, 17.48 in. wide, and 25 in. deep. The chassis installs in standard 600-mm deep (or larger) enclosed cabinets or 19-in. equipment racks.

CAUTION: Before removing or installing components of a functioning services gateway, attach an electrostatic discharge (ESD) strap to an ESD point and place the otherendofthestraparoundyourbarewrist. FailuretouseanESDstrapcouldresult in damage to the device.

The services gateway must be connected to earth ground during normal operation.

SRX4200CoolingSystem

The cooling system for the services gateway consists of four fan trays located at the rear of the chassis. Eachfantraycontainstwofans,sothereareatotalofeightfans. Thefansdrawcoolairthroughventson

the front of the chassis and exhaust the air through the back of the chassis. See Figure 6 on page 24. The airflow produced by the fans keeps device components within the acceptable temperature range.

If any one of the four fan trays fails, the services gateway generates a warning but keeps the system running.Ifthetemperaturekeepsrising,theservicesgatewaylowersthepowerconsumptionbyreducing the performance or shutting down some of the chassis components. However, if the ambient maximum temperature exceeds the warning level and the system cannot be adequately cooled, then the services gateway shuts down the system and hardware components completely.

The fan trays are hot-swappable field-replaceable units (FRUs). The fans are not field-replaceable.
