Use this guide to install hardware and perform initial software configuration, routine maintenance, and
troubleshooting for the ACX2000 and ACX2100 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
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.

ACX2000 Router Description | 18
ACX2100 Router Description | 19
The ACX2000 and ACX2100 Universal Metro Routers are principally designed to provide superior
management for rapid provisioning to the access network. The ACX Series routers support rich Gigabit
Ethernet and 10-Gigabit Ethernet capabilities for uplink, along with support for legacy interfaces and
Gigabit Ethernet interfaces for radio and NodeB connectivity in a compact form factor that is
environmentally hardened and passively cooled. Seamless, end-to-end MPLS can be used to address legacy
and emerging requirements to provide the foundation for a converged network that utilizes the same
mobile backhaul infrastructure for business or residential services.
The ACX Series router is a single-board router with a built-in Routing Engine and one Packet Forwarding
Engine. Because there is no switching fabric, the single Packet Forwarding Engine takes care of both ingress
and egress packet forwarding:
Routing Engine—Provides Layer 3 routing services and network management.
Packet Forwarding Engine—Performs Layer 2 and Layer 3 packet switching, route lookups, and packet
forwarding.
17
The ACX Series router is powered by Junos OS, supporting extensive L2 and L3 features, IP and MPLS
with traffic engineering, rich network management, fault management, service monitoring and Operation,
Administration, and Maintenance (OAM) capabilities, and an open software development kit (SDK) system
that allows providers to customize and integrate operations with their own management systems. For a
list of related Junos OS documentation, see https://www.juniper.net/documentation/software/junos/.
As part of the mobile backhaul, the ACX Series router at the cell site and the MX Series router at the
aggregation layer provide comprehensive end-to-end Ethernet, MPLS, and OAM features with the one
Junos OS running on both platforms.
The compact routers are one rack unit (U; that is, 1.75 in., or 4.45 cm) tall. Several routers can be stacked
in a single floor-to-ceiling rack for increased port density per unit of floor space.
The chassis is a rigid sheet metal structure that houses all the other router components. The chassis
measures 1.75 in. (4.45 cm) high, 9.4 in. (24 cm) deep, and 17.5 in. (44.5 cm) wide. The outer edges of the
mounting brackets extend the width to 19 in. (48 cm) (from the front-mounting brackets to the rear of the
chassis). The chassis installs in standard 300-mm deep (or larger) enclosed cabinets, 19-in. equipment
racks, or telco open-frame racks.
Benefits of the ACX2000 and ACX2100 Routers
Improved operational efficiency with zero-touch deployment (ZTD)—The ACX Series routers support
a zero-touch deployment (ZTD) model that significantly reduces the time for any new equipment
installation and provisioning, resulting in improved operational efficiency.
Installation flexibility with an environmentally hardened design—Most ACX Series routers are temperature
hardened and support passive cooling for outdoor deployments in extreme weather conditions.
ACX2000 Router Description
The ACX2000 router contains sixteen T1/E1 ports, six Gigabit Ethernet ports, and two PoE ports. The
ACX2000 router also supports installation of two Gigabit Ethernet SFP transceivers and two 10-Gigabit
Ethernet SFP+ transceivers.
The ACX2000 router has one “pseudo” Flexible PIC Concentrator (FPC 0), and four “pseudo” PICs (PIC 0
through 3).
Figure 1 on page 19 shows the front view of the ACX2000 router. Figure 2 on page 19 shows the rear

ACX2100 Router Description
The ACX2100 router contains sixteen T1/E1 ports, and four Gigabit Ethernet ports. The ACX2100 router
also contains two ports for installing Gigabit Ethernet SFP transceivers and two ports for installing 10-Gigabit
Ethernet SFP+ transceivers. The ports labeled COMBO PORTS provide an additional four copper Gigabit
Ethernet ports or four Gigabit Ethernet SFP ports. You can use only one set of combination ports at a time.
The ACX2100 router has two “pseudo” Flexible PIC Concentrators (FPC 0 and FPC 1), and four “pseudo”
PICs (PIC 0 through 3).
