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.

Only one power supply unit is plugged in.
•
The AC power cord is not plugged in.
•
The power supply unit is not functional and there is no DC output.
•
For personal safety, while working on the services gateway, use the ESD outlet
to plug in an ESD grounding strap to prevent your body from sending static
charges to the services gateway.
Four fan trays for cooling the services gateway and its components. Each fan
tray contains two fans.
Three fan trays are required for proper air flow across the chassis internal
components. The fourth fan tray provides redundancy.
Two power supply slots. Each power supply contains a power cord outlet. Two
650-W DC or AC power supplies are provided with the services gateway.
SRX4100 Cooling System
The cooling system for the services gateway consists of four fan trays located at the rear of the chassis.
Each fan tray contains two fans, so there are a total of eight fans. The fans draw cool air through vents on
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. If the temperature keeps rising, the services gateway lowers the power consumption by reducing
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.

25
The SRX4100 Services Gateway is shipped with two AC or two DC power supply units preinstalled in the
rear panel. Each power supply provides power to all components in the services gateway. If one power
supply fails or is removed, the remaining power supply redistributes the electrical load without interruption.
Each power supply is cooled by its own internal cooling system.
AC Power Supply
Each AC power supply weighs approximately 2.3 lb and consists of one AC appliance inlet, a fan, and LEDs
for monitoring the status of the power supply. The AC power supply is a hot-insertable and hot-removable
field-replaceable unit (FRU) when the second power supply is installed and running. You can install the
replacement power supply without powering off the services gateway. The AC power supply gives an
output of 650 W and supports both low line voltage (100–127 VAC) and high line voltage (200–240 VAC).
Figure 7 on page 25 shows the AC power supply.

NOTE:
If both the AC LED and the DC LED are unlit, either the AC power cord is not installed properly
•
or the power supply fuse has failed.
If the AC LED is lit and the DC LED is unlit, the AC power supply is installed properly, but the
•
power supply has an internal failure.
DC Power Supply
Each DC power supply weighs approximately 2.2 lb and has two independent pairs of DC input lugs, a fan,
and LEDs for monitoring the status of the power supply. The DC power supply in the services gateway is
a hot-insertable and hot-removable field-replaceable unit (FRU) when the second power supply is installed
and running. You can install a replacement power supply without powering off the services gateway. The
DC power supply gives an output of 650 W. Figure 9 on page 27 shows the DC power supply.

Figure 9: DC Power Supply
The DC power supply requires a dedicated circuit breaker rated for 9 A (–48 VDC) minimum, or as required
by local code.
Figure 10 on page 27 shows the location of the LEDs on a DC power supply. Each DC power supply
faceplate contains three LEDs that indicate the status of the power supplies.
