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.
ix

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
x

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.

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
17

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.
Front Panel
The front panel of the optical ILA contains six LC port connectors, the ON/OFF button, the console and
management ports, the system status LEDs, and the USB ports. Figure 2 on page 18 shows the front panel
of the optical ILA.

FRU Panel
The field-replaceable unit (FRU) panel of the optical ILA contains the fan modules and power supplies for
the optical ILA. Figure 3 on page 19 shows the FRU panel on the optical ILA.

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.
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.
Table 4: Required Actions Before Removing a FRU from the Optical ILA
Required Actions Before RemovalFRU
Disconnect the AC power and remove the AC power cord or cable for the power supply
unit.
Disconnect the DC power and remove the power connector.
NOTE: You need a minimum of one powered power supply for the optical ILA to operate
properly.
