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 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;
}
}
}
}
x
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; }
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]
xi
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.

About the SRX100 Services Gateway
The Juniper Networks SRX100 Services Gateway offers features that provide complete functionality and
flexibility for delivering secure Internet and intranet access. The services gateway offers stable, reliable,
and efficient IP routing in addition to switching support and LAN connectivity. The device provides IP
Security (IPsec), virtual private network (VPN), and firewall services for small and medium-sized companies
and enterprise branch and remote offices. The SRX100 Services Gateway can be connected directly to
traditional private networks such as leased lines, Frame Relay, or Multi Protocol Label Switching (MPLS)
or to the public Internet.
The SRX100 Services Gateway runs the Junos operating system (Junos OS).
SRX100 Services Gateway Models
The following are the two models of the SRX100 Services Gateway available with 1 GB memory. For
information on the models with 2 GB memory, see SRX100 Services Gateway Hardware Guide for H2
Model Numbers.

NOTE: You can upgrade from an SRX100 Services Gateway Low Memory version to a High
Memory version through a license key. You need not order a separate High Memory device.

NOTE: SRX100H model provides additional security features such as Unified Threat Management
(UTM), which consists of IPS antispam, antivirus, and Web filtering.
NOTE: The SRX100 Services Gateway High Memory model ships with a license key.
All SRX100 Services Gateways run the Junos OS.
Accessing the SRX100 Services Gateway
Two user interfaces are available for monitoring, configuring, troubleshooting, and managing the SRX100
Services Gateway:
J-Web interface: Web-based graphical interface that allows you to operate a services gateway without
•
commands. The J-Web interface provides access to all Junos OS functionality and features.
Junos OS command-line interface (CLI): Juniper Networks command shell that runs on top of a UNIX-based
•
operating system kernel. The CLI is a straightforward command interface. On a single line, you type
commands that are executed when you press the Enter key. The CLI provides command Help and
command completion.

Boot Devices | 10

This topic includes the following sections:
Boot Devices
The SRX100 Services Gateway can boot from the following storage media (in the order of priority):
Internal NAND Flash (default; always present)
•
USB storage key (alternate)
•
Dual-Root Partitioning Scheme
Dual-root partitions allow the SRX100 Services Gateways to remain functional if there is file system
corruption and facilitate easy recovery of the corrupted file system.
The dual-root partitioning scheme keeps the primary and backup Junos OS images in two independently
bootable root partitions. If the primary root partition becomes corrupted, the system will be able to boot
from the backup Junos OS image located in the other root partition and remain fully functional.
When the SRX100 Services Gateway powers up, it tries to boot the Junos OS from the default storage
media. If the device fails to boot from the default storage media, it tries to boot from the alternate storage
media. With the dual-root partitioning scheme, the SRX100 Services Gateway first tries to boot the Junos
OS from the primary root partition and then from the backup root partition on the default storage media.
If both primary and backup root partitions of a media fail to boot, then the device tries to boot from the
next available type of storage media. The SRX100 Services Gateway remains fully functional even if it
boots the Junos OS from the backup root partition of storage media.
NOTE: SRX Series devices that ship from the factory with Junos OS Release 10.0 are formatted
with the dual-root partitioning scheme.
The SRX100 Services Gateways that are running Junos OS Release 9.6 or earlier use the single-root
partitioning scheme. While upgrading these devices to Junos OS Release 10.0, you can choose to format
the storage media with dual-root partitions (strongly recommended) or retain the existing single-root
partitioning.
