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.

The Juniper Networks Optical Inline Amplifier is a stand-alone erbium-doped fiber amplifier (EDFA) with
dual AC or DC power supplies. The optical inline amplifier (ILA) supports bidirectional optical inline
amplification. The optical ILA provides periodic amplification of a dense wavelength-division multiplexing
(DWDM) signal to enable long-distance transmission as it propagates along the fiber-optic cable. Optical
ILAs are typically placed between 50 miles (80 km) and 62 miles (100 km) apart along the length of the
fiber. They are used in conjunction with the integrated photonic line cards (IPLCs) that are installed in the
Juniper Networks PTX3000 Packet Transport Routers. An optical ILA connects to an IPLC through the
LINE IN and LINE OUT LC port connectors on the front panel. It also connects to other optical ILAs through
the same LC port connectors.
The optical ILA operates with redundant hot-swappable pluggable power supplies that are either AC or
DC. The optical ILA can be managed by using Connectivity Services Director (CSD), or by using the CLI
console commands. The optical ILA does not run the Juniper Networks Junos operating system (Junos
OS).
Starting with Junos OS release 17.1, you can control and manage optical inline amplifiers (ILA) over the
optical supervisory channel (OSC) of the PTX3000 integrated photonic line system. For information about
managing the ILAs over the OSC of the the IPLCs, see the Integrated Photonic Line Card (IPLC) System User
Guide.
Figure 1 on page 18 shows a point-to-point configuration with the optical ILA and IPLC.
Figure 1: Point-to-Point Configuration
In this example, the optical ILA is connected to the IPLC in the PTX3000 chassis, which is connected to
compatible PICs in the same chassis through the add and drop ports. The multiplexed wavelengths from
the IPLC are amplified and transmitted in a single fiber toward the line (through the Line OUT port on the
IPLC), which is connected to the optical ILA (through the LINE IN port on the ILA). Based on the distance,
you can have multiple ILAs connected. In this example, there are three ILAs to enable long-distance
transmission.

For more information about the IPLCs, see the PTX3000 Packet Transport Router Hardware Guide. For
information about configuring the IPLCs, see the Integrated Photonic Line Card (IPLC) System User Guide.

The cooling system in an optical ILA consists of three 12.4-W fan modules. These fan modules can be
hot-swapped—you do not need to power off the optical ILA or disrupt the functioning of the optical ILA
to replace a fan module. The optical ILA has two 150-W power supplies, either AC or DC depending on
your configuration. The power supplies need to be both AC or both DC. Only one power supply is required
to power the device, while the second power supply provides redundancy.

Optical ILA Component Redundancy
The following hardware components provide redundancy on the optical ILA models:
Cooling system—The optical ILA has three fan modules. Each fan module is a redundant unit containing
•
one fan. If a fan module fails and the remaining fan modules are unable to keep the optical ILA within
the desired temperature thresholds, chassis alarms are raised and the optical ILA can shut down.
The optical ILA ships with two power supplies that provide 1+1 redundancy. If one power supply fails
•
or is removed, the second power supply balances the electrical load without interruption and still provides
1+1 redundancy while the failing power supply is replaced.
Optical ILA Field-Replaceable Units
Field-replaceable units (FRUs) are components that you can replace at your site. The optical ILA FRUs are
hot-removable and hot-insertable—you can remove and replace them without powering off the optical
ILA or disrupting the optical ILA function.
20
CAUTION: Replace a failed fan module with a new fan module within 30 seconds of
removal to prevent chassis overheating.
Table 4 on page 20 lists the FRUs for the optical ILA and actions to take before removing them.

The cooling system in an optical ILA consists of three 12.4-W fan modules. The fan modules can be
hot-swapped—you do not need to power off the optical ILA or disrupt the optical ILA function to replace
a fan module.
The optical ILA has two 150-W power supplies, either AC or DC depending on your configuration. The
power supplies need to be both AC or both DC—you cannot mix AC and DC power supplies in the same
chassis. Only one power supply is required to power the device, while the second power supply provides
redundancy. When the optical ILA has both power supplies installed and connected to power, the device
has full power redundancy. If a power supply fails or is removed, another power supply balances the
electrical load without interruption. Each power supply provides 12 VDC output with a standby voltage
of 12 VDC. The power supplies can be hot-swapped—you do not need to power off the optical ILA or
disrupt the optical ILA function to replace a power supply.

For more information about the components on the FRU panel, see “Optical ILA Cooling System Description”
on page 29, “Optical ILA AC Power Supply Description” on page 31, and “Optical ILA DC Power Supply
Description” on page 32.
Optical ILA Chassis Status LEDs
The optical ILA has five status LEDs on the front panel of the chassis (see Figure 8 on page 25)—two optical
supervisory channel (OSC) status LEDs (OSC A and OSC B), a system status LED (SYS), an alarm LED (ALM),
and a power LED (PWR). The OSC is a separate channel that carries overhead information for network
management purposes. The OSC, which is an important section in every DWDM system, is a separate
channel that carries overhead information for network purposes. For instance, it carries data between
sites for monitoring and controlling specifications in the system.

The optical ILA is powered off or there
is no power to the device.
The optical ILA is powered by a single
power supply. The second power
supply is either missing or not
connected to a power source.
The optical ILA is powered with two
redundant power supplies.
Optical ILA Management Panel
The optical ILA management panel is found on the front panel (see Figure 9 on page 27).

You manage the optical ILA by using the command-line interface (CLI), which is accessible through the
console and out-of-band management ports on the management panel. In addition, the front panel has
system status LEDs (see Table 4 in “Optical ILA Chassis Status LEDs” on page 24) that alert you to minor
or major alarms or other issues with the amplifier. Figure 9 on page 27 shows the management panel in
detail.

You can also manage the optical ILA through Connectivity Services Director (CSD), which is a Junos Space
application developed to manage the optical functionality provided by optical ILAs and integrated photonic
line cards (IPLCs) that are installed in the PTX3000 routers. CSD is managed over a data communications
network (DCN). CSD presents a topological network view in an intuitive, comprehensive, and cohesive
manner that enables you to visualize optical sites, links, and services and a site view that provides status,
configuration, alarms/faults, and performance monitoring functionality on the optical interfaces. By using
CSD, you can perform the following tasks on an optical ILA:
View the optical interface specifications that are currently applied on the device, such as wavelength
•
and power.
Modify the existing parameters of the optical port to suit your network needs or resolve any alarms
•
caused by certain interface settings.
View the active alarms generated for the optical interface to analyze and resolve the condition that
•
triggered the alarm on the device.
Configure threshold crossing alarms (TCAs) for the optical interface.
•
View the performance monitoring details in statistical and graphical formats for the optical interface.
•
NOTE: See the Connectivity Services Director User Guide for more information.

Optical ILA Management Port LEDs
The management port—labeled MGMT—on the optical ILA is located on the management panel.
The management port is an Ethernet port that supports an RJ-45 connector and has separate LEDs for
status and activity. Figure 10 on page 28 shows the location of the LEDs.

Link is up.
There is data activity.
The cooling system in an optical ILA consists of three 12.4-W fan modules installed in the field-replaceable
unit (FRU) panel and two counter-rotating fans housed in each of the power supplies.
In the optical ILA's cooling system, cool air enters through the vents in the front panel and hot air exhausts
through the fans in the FRU panel. This type of airflow is known as airflow out or front-to-back airflow.
When installed, the chassis must be positioned so that the FRUs are next to the hot air exhaust.
NOTE: Under normal operating conditions, the fan modules operate at a moderate speed.
Temperature sensors in the chassis monitor the temperature within the chassis. The system
raises an alarm if a fan module fails or if the ambient temperature inside the chassis rises above
the acceptable range.
Fan Modules
The fan modules in an optical ILA are hot-removable and hot-insertable FRUs. These fan modules can be
hot-swapped—you do not need to power off the optical ILA or disrupt the optical ILA function to replace
a fan module. The fan module slots are numbered 0 through 2 from left to right when viewing chassis from
the FRU panel side (see Figure 11 on page 30). Figure 12 on page 30 shows the fan module for the optical
ILA. The numbers are located on the top of the chassis.

NOTE: All three fan modules must be installed for optimal operation of the optical ILA. The
optical ILA continues to operate for a period of 30 seconds during the replacement of the fan
module without thermal shutdown.
