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.
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:
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.

ACX5048 Router | 18
ACX5096 Router | 19
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.
For more information about which features are supported on an ACX5000 routers, see “Protocols and
g000810
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.

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.
Table 4: FRUs in ACX5000 Routers and Action Required Before Removing Them
Required ActionFRUs
NonePower supplies
NoneFan modules
CAUTION: Replace a failed power supply with a blank panel or new power supply
within one minute of removal to prevent chassis overheating. The router continues to
operate with only one power supply running. Replace a failed fan module with a new
fan module within one minute of removal to prevent chassis overheating. Do not
operate the router with missing FRUs for longer than one minute.
NOTE: If you have a Juniper J-Care service contract, register any addition, change, or upgrade
of hardware components at
https://www.juniper.net/customers/csc/management/updateinstallbase.jsp . Failure to do so
can result in significant delays if you need replacement parts. This note does not apply if you
replace existing components with the same type of component.
21
NOTE: Before removing the optical transceivers, we recommend that you disable the interface
using the set interfaces interface-name disable command. See “Disconnecting a Fiber-Optic
Cable from an ACX5000 Router” on page 130.

Understanding Hardware Redundancy of an ACX5000 Router Components
and Functionality
The following hardware components provide redundancy on an ACX5000 router:
Power supplies—The ACX5000 router has one or two power supplies. Each power supply provides
•
power to all components in the router. If two power supplies are installed, the two power supplies
provide full power redundancy to the device. If one power supply fails or is removed, the second power
supply balances the electrical load without interruption.
To provide power redundancy to the system both power supplies must be installed. Connect power
source feed A to one power supply and power source feed B to the second power supply.
CAUTION: Do not connect feed A and feed B to the same power supply input
terminal.
22
Cooling system—The 1 U ACX5048 router has five fan modules; the 2 U ACX5096 router has three fan
•
modules. If a fan module fails and is unable to keep the ACX5000 router within the desired temperature
thresholds, chassis alarms occur and the ACX5000 router can shut down.
