Requesting Technical Support | xiv
Use this guide to install hardware and perform initial software configuration, routine maintenance, and
troubleshooting for the ACX5048 and ACX5096 Universal Metro 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
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 ACX5000 Universal Metro Routers are Juniper Networks’ top-of-rack router solutions for data centers
and campus distribution or aggregation environments. The ACX5000 router portfolio consists of
high-performance fixed-configuration routers that add higher port densities, additional scalability, and
improved latency to the ACX Series. The ACX5000 routers are available in two models—ACX5048 and
ACX5096. See “ACX5000 Router Models” on page 19.
ACX5000 routers offer a compact 1 U model and a 2 U model that provide wire-speed packet performance,
very low latency, and a rich set of Layer 2 and Layer 3 features. These routers have a high-throughput
Packet Forwarding Engine, and the performance of the control plane running on ACX5000 routers is
enhanced by the 1.5 Ghz dual-core Intel CPU with 8 GB of memory and 32 GB of solid-state drive (SSD)
storage.
The ACX5000 routers include both 10-Gigabit Ethernet and 40-Gigabit Ethernet fixed configurations.
17

For more information about which features are supported on an ACX5000 routers, see “Protocols and
Applications Supported by ACX Series Routers” on page 26.
ACX5000 routers use the Junos operating system (OS), which provides Layer 2 and Layer 3 switching,
routing, and security services. Junos OS is installed on an ACX5000 router’s 32-gigabyte (GB) internal solid
state flash drive. The same Junos OS code base that runs on an ACX5000 routers also runs on all Juniper
Networks QFX and EX Series switches, and J Series, M Series, MX Series, ACX Series and T Series routers.
You manage the router using the Junos OS command-line interface (CLI), accessible through the console
and out-of-band management ports on the router.
Benefits of the ACX5048 and ACX5096 Routers
•Performance—ACX5000 routers provide wire-speed packet performance, very low latency, and a rich
set of Layer 2 and Layer 3 features.
•Service virtualization—ACX5000 routers offer service virtualization on a dedicated and customizable
KVM-compliant virtual machine that enables you to execute operational scripts and programs for network
performance monitoring and analysis.
ACX5048 Router
As shown in Figure 1 on page 18, the ACX5048 is a 10-Gigabit Ethernet enhanced small form-factor
pluggable (SFP+) top-of-rack router with 48 SFP+ ports and 6 quad SFP+ (QSFP+) ports. Each SFP+ port
can operate as a native 10-Gigabit Ethernet port or as a 1-Gigabit Ethernet port when 1-gigabit optics are
inserted. Each QSFP+ port (48 through 53) can operate as a 40-Gigabit Ethernet port or be channelized
to operate as four independent 10-Gigabit Ethernet ports (a total of 24 10-Gigabit Ethernet ports). The
6 QSFP+ ports can be used as either access ports or uplink ports. The ACX5048 provides full duplex
throughput of 1.44 Tbps. The ACX5048 has a 1 U form factor and is shipped with redundant fans and
redundant power supplies. The router can be ordered with front-to-back airflow (air out or AFO) and with
AC or DC power supplies.

ACX5048 can be used only as a standalone router.
18

ACX5096 Router
As shown in Figure 2 on page 19, the ACX5096 is a is a 10-Gigabit Ethernet enhanced small form-factor
pluggable (SFP+) top-of-rack router with 96 SFP+ ports and 8 quad SFP+ (QSFP+) ports. Each SFP+ port
can operate as a native 10-Gbps port or as a 1-Gbps port. The QSFP+ ports 96 and 100 can operate at
native 40 Gbps speed or can be channelized to 4 independent 10 Gbps port speeds. The 8 QSFP+ ports
can be used as either access ports or as uplinks. The ACX5096 has a 2 U form factor and is shipped with
redundant fans and redundant power supplies. The router can be ordered with front-to-back airflow (air
out or AFO) and with AC or DC power supplies.

Field-Replaceable Units in an ACX5000 Router
Field-replaceable units (FRUs) are components that you can replace at your site. The ACX5000 FRUs are
hot-insertable and hot-removable: you can remove and replace them without powering off the router or
disrupting the routing function.
The following are the ACX5000 FRUs:
•Power supplies
•Fan modules
Table 4 on page 21 lists the FRUs for the ACX5000 and actions to take before removing them.
