Documentation and Release Notes
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/.
If the information in the latest release notes differs from the information in the
documentation, follow the 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.
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
isasnippet. In this case, use the load merge relative command. These procedures are
described in the following sections.
xiCopyright © 2019, Juniper Networks, Inc.

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;
}
}
}
}
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; }
Copyright © 2019, Juniper Networks, Inc.xii
SRX4100 Services Gateway Hardware Guide

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.

SRX4100 Services Gateway Overview
The Juniper Networks SRX4100 Services Gateway is a high-performance, scalable
mid-range services gateway, which consolidates security, next-generation firewall, and
advanced threat prevention capabilities to provide secure connectivity. The services
gateway supports 20 Gbps IMIX throughput and is suited for small to medium enterprises
and data centers.
The SRX4100 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:
•SRX4100 (AC) — SRX4100 Services Gateway with dual AC power supplies
•SRX4100 (DC) — SRX4100 Services Gateway with dual DC power supplies
The SRX4100 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.

Field-Replaceable Units in SRX4100 Services Gateways
Field-replaceable units (FRUs) are components that you can replace at your site. The
FRUs on the SRX4100 Services Gateway are hot-removable and hot-insertable. You can
remove and replace them without powering off the services gateway. The services
gateway supports the following FRUs:
•AC power supplies
•DC power supplies
•Fan trays
See Also SRX4100 Power Supply on page 23•
Benefits of the SRX4100 Services Gateway
•High performance—The SRX4100 supports up to 40-Gbps firewall throughput (up to
20-Gbps of IMIX firewall throughput) and is suited for enterprise campus and data
center edge deployments.
•Advanced threat protection—The SRX4000 line of services gateways supports the
intrusion prevention system (IPS), Juniper Sky Advanced Threat Prevention (Juniper
Sky ATP), antivirus, and antispam features, which protect against potential
vulnerabilities. Juniper Sky ATP protects against zero-day attacks and other unknown
threats.

SRX4100 Services Gateway Chassis Overview
The 4100 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 other end of the strap around your bare wrist. Failure to use an ESD
strap could result in damage to the device.
