Requesting Technical Support | xiv
Use this guide to install hardware and perform initial software configuration, routine maintenance, and
troubleshooting for the ACX5448 Router.
After completing the installation and basic configuration procedures covered in this guide, refer to the
Junos OS documentation for information about further software configuration.
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
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;
}
}
}
}
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.

ACX5448, ACX5448-D, and ACX5448-M System Overview | 21
The Juniper Networks ACX5400 Universal Metro Routers are top-of-rack routers with deep packet buffer
solutions for metro network or aggregation environments. The ACX5400 router portfolio consists of
high-performance, fixed-configuration, 1 U routers that add higher port densities, additional scalability,
and improved latency to the ACX Series. The routers have a high-throughput Packet Forwarding Engine,
which provides full duplex throughput of 800 Gbps.
The ACX5400 line of routers are available in three variants:
ACX5448
ACX5448-D
ACX5448-M

Benefits of ACX5400 Routers
Optimized space—The ACX5400 router has a 1 U form factor and is ideal for Ethernet service aggregation.
Its innovative design helps service providers build high-density, high-performance 100-Gigabit Ethernet
infrastructures where rack space and cooling are limited.
High performance
The 52 ports on the ACX5448 router support 10-Gbps and 100-Gbps speeds providing a total
throughput of up to 800 Gbps. The router provides full metro Ethernet and IP/MPLS VPN services in
a space-optimized platform.
The ACX5448-D router supports 10-Gigabit, 100-Gigabit, and 100G/200G dense wavelength-division
multiplexing (DWDM) ports with a system throughput of up to 800 Gbps. The innovative design of
the ACX5448-D helps service providers develop converged packet optical solutions.
Simplified network architecture The ACX5400 line of routers simplify access and aggregation
architectures by eliminating unnecessary layers and network overlays.
Advanced security capabilities The ACX5448-M router supports advanced security capabilities such
as Media Access Control Security (MACsec) on the 10-Gigabit or 1-Gigabit Ethernet ports to protect
against potential network vulnerabilities.
ACX5448, ACX5448-D, and ACX5448-M System Overview
The ACX5400 routers have a high-throughput Packet Forwarding Engine, and the performance of the
control plane running on ACX5400 routers is enhanced by the 1.9-Ghz six-core Intel CPU with 32-GB of
memory and two 100-GB enterprise-grade solid-state drives (SSDs) for storage.
We ship the ACX5400 routers with redundant fans and redundant power supply modules (PSMs). You
can order the routers with front-to-back airflow (airflow out or AFO) or back-to-front airflow (airflow in
or AFI), and with AC or DC PSMs.
Figure 7 on page 22 shows the important components on the front of the ACX5448 router.
