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.
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
isasnippet. In this case, use the load merge relative command. These procedures are
described in the following sections.
xiiiCopyright © 2019, Juniper Networks, Inc.

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
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; }
Copyright © 2019, Juniper Networks, Inc.xiv
QFX10002 Switch Hardware Guide

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.

QFX10002 System Overview
The Juniper Networks QFX10002 is a fixed configuration data center switch. As part of
the QFX10000 line of aggregation and spine switches, the QFX10002 models provide
the flexibility of 10-Gbps, 40-Gbps, and 100-Gbps port speeds in a 2 U fixed configuration.
For more information, see the following topics:
•QFX10002 Switch Description on page 19
•QFX10002 Hardware Component Overview on page 23
•QFX10002 Component Redundancy on page 24
•QFX10002 Field-Replaceable Units on page 26
QFX10002 Switch Description
The Juniper Networks QFX10002 is a fixed configuration data center switch that offers
a variety of port densities and network port configurations. This topic covers:
•Benefits of the QFX10002 Switch on page 20
•QFX10002 Models on page 20
•System Architecture on page 22
•Cooling and Power on page 22
•System Software on page 23

Benefits of the QFX10002 Switch
•Combats application latency by using a deep buffer with hybrid memory cube (HMC)
technology to absorb network traffic spikes. Deep buffers are important at the edge
of data center networks where typically there is a speed mismatch between WAN-facing
interfaces and data center-facing interfaces.
•Operates as a universal switch and can be positioned in multiples roles (data center,
data center interconnect, or data center edge) because of its high logical scale.
•Enables cloud providers to collapse multiple layer in the network (spine and data center
interconnect) that offer capital and operational expenditure savings.
•Saves on power with an optimized power profile per 100 Gigabit Ethernet.
QFX10002 Models
The QFX10002 line of switches are deep-buffer fixed-chassis switches in a 2 U form
factor for fixed core and spine deployments. All models of the QFX10002 support port
densities of 10 Gigabit Ethernet, 40 Gigabit Ethernet and 100 Gigabit Ethernet. In addition,
all switches are available with either an AC or DC power supply and with port to field
replaceable unit (FRU) cooling. This type of cooling is also known as airflow out (AFO)
or front-to-back cooling. The QFX10002 is available in three port configurations:
•QFX10002-36Q
•QFX10002-72Q
•QFX10002-60C
The QFX10002-36Q offers 36 ports of 40-Gigabit Ethernet quad small-form factor
plugable (QSFP+) or 12 ports 100-Gigabit Ethernet 28-Gbps QSFP+ Pluggable Solution
(QSFP28). The QFX10002-36Q has up to 2.88 terabits per second (Tbps) of throughput
and 1 billion packets per second (Bpps) of forwarding capacity. This model ships with
redundant 1600 W AC or DC power supplies and three fan modules. See
Figure 1 on page 20.
Figure 1: QFX10002-36Q Port Panel
g050401
The QFX10002-72Q offers double capacity of the QFX10002-36Q with 72 ports of QSFP+
or 24 ports of QSFP28. It has up to 5.76 Tbps of throughput and 2 Bpps of forwarding
capacity. This model ships with 4 redundant 1600 W AC or DC power supplies and three
fan modules. See Figure 2 on page 21.
