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;
}
}
}
}
xi
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]
xii
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.

SRX550 Services Gateway Power over Ethernet
Power over Ethernet (PoE) supports the implementation of the IEEE802.3 af and IEEE802.3 at standards,
which allow both data and electric power to pass over a copper Ethernet LAN cable.
The SRX550 Services Gateway provides PoE ports, which supply electric power over the same ports that
are used to connect network devices. PoE ports allow you to plug in devices that require both network
connectivity and electric power, such as Voice over IP (VoIP) and IP phones and wireless access points.
The PoE ports for the SRX550 Services Gateway reside on the individual XPIMs. The SRX550 Services
Gateway supports the following XPIMs with PoE:
16-Port Gigabit Ethernet XPIM
•
24-Port Gigabit Ethernet XPIM
•
The Services and Routing Engine (SRE) manages the overall system PoE power. You can configure the
services gateway to act as power sourcing equipment to supply the power to the GPIMs connected on
the designated PoE ports.
Table 4 on page 10 lists the SRX550 Services Gateway PoE specifications.

You can use two user interfaces to monitor, configure, troubleshoot, and manage the Juniper Networks
Services Gateway:
The J-Web interface: A 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.

SRX550 Services Gateway Boot Devices and Dual-Root Partitioning Scheme
By default, the SRX550 Services Gateway boots from the following storage media (in order of priority):
12
1. Internal CompactFlash card (default; always present)
2. USB storage key (alternate)
NOTE: When you explicitly boot the services gateway using the CLI and the services gateway
has two USBs installed (one in slot 0 and the second in slot 1), if the USB in slot 0 fails, the
booting sequence will not boot from the second USB installed in slot 1. Instead, the device will
boot using the next storage media in its storage media booting priority list, the internal
CompactFlash card.
The dual-root partitions allow the 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 is 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 services gateway powers up, it tries to boot 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 device first tries to boot 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 Junos OS from the next available type of
storage media. The services gateway remains fully functional even if it boots the Junos OS from the backup
root partition of storage media.

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.
