Requesting Technical Support | xiii
Use this guide to install hardware and perform initial software configuration, routine maintenance, and
troubleshooting for the SRX340 Services Gateway. After completing the installation and basic configuration
procedures covered in this guide, refer to the Junos OS documentation for information about further
software configuration.
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.
viii

If the example configuration contains the top level of the hierarchy (or multiple hierarchies), the example
isafull 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 is a snippet. In
this case, use the load merge relative command. These procedures are described in the following sections.
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
ix

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; }
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.

SRX340 Services Gateway Description
The SRX340 Services Gateway consolidates security, routing, switching, and WAN interfaces for midsize
distributed enterprises. With advanced threat mitigation capabilities, the services gateway provides
cost-effective and secure connectivity across distributed enterprises.
The SRX340 Services Gateway has a capacity of 3 gigabits per second (Gbps) and is 1 rack unit (U) tall.
The services gateway has eight 1 G Ethernet ports, eight 1 G SFP ports, one management port, 4 GB of
DRAM memory, 8 GB of flash memory, and four Mini-Physical Interface Module (Mini-PIM) slots.
The SRX340 Services Gateway runs the Junos operating system (Junos OS) and supports the following
features:
•Firewall support with key features such as IPsec and VPN
•Intrusion Detection and Prevention (IDP)
•High availability
•QoS
•MPLS
You can manage the SRX340 Services Gateway by using the same interfaces that you use for managing
other devices that run Junos OS—the CLI, the J-Web graphical interface, and Junos Space.
SRX340 Services Gateway Field Replaceable Units Overview
Field-replaceable units (FRUs) are components that you can replace at your site. The Mini-Physical Interface
Module (MPIM) is the only FRU on the SRX340 Services Gateway.
16

The Mini-PIMs are not hot-swappable. You must power off the services gateway before removing or
installing Mini-PIMs.

Benefits of the SRX340 Services Gateway
•High performance—The SRX340 supports up to 3-Gbps firewall and 600-Mbps IPsec VPN, and is suited
for midsize distributed enterprise branch office deployments.
•Simplified deployment with minimal manual intervention—The Zero Touch Provisioning (ZTP) feature
enables you to provision and configure the SRX300 line automatically, thereby reducing operational
complexity and simplifying the provisioning of new sites.
•Multiple WAN connectivity options—The SRX340 supports multiple options such as Ethernet, serial,
T1/E1, VDSL2, and 3G/4G LTE wireless for WAN or Internet connectivity to link sites.
•Threat protection—The SRX300 line supports IPsec VPN, Media Access Control Security (MACsec),
Juniper Sky Advanced Threat Prevention, and Trusted Platform Module (TPM) to protect against potential
vulnerabilities.

SRX340 Services Gateway Chassis Overview
The SRX340 Services Gateway chassis is a rigid sheet metal structure that houses all of the other services
gateway components. The chassis measures 1.72 in. (4.36 cm) high, 17.36 in. (44.09 cm) wide, and 14.57
in. (37.01 cm) deep (from the front to the rear of the chassis). The chassis installs in standard 800–mm (or
larger) enclosed cabinets, 19 in. equipment racks, or telecommunications open-frame 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.
The services gateway must be connected to earth ground during normal operation. The protective earthing
terminal on the side of the chassis is provided to connect the services gateway to ground.
