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 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;
}
}
}
}
xi
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; }
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]
xii
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.

QFX5200 line of switches offer compact 1 U models that provide a line rate configuration packet
performance, very low latency, and a rich set of Layer 3 features.
QFX5200-32C and QFX5200-32C-L Hardware
The QFX5200-32C and QFX5200-32C-L are compact 1 U standalone switches that provides a line rate
configuration packet performance, very low latency, and a rich set of Layer 3 features. The routing engine
and control plane are driven by the 1.8 Ghz quad-core Intel CPU with 16 GB of memory and two 32 GB
solid-state drives (SSD) for storage. The QFX5200-32C models run standard Junos Operating System (OS);
the QFX5200-32C-L models run Junos OS Evolved.
19
As shown in Figure 1 on page 19, the QFX5200-32C and QFX5200-32C-L are 100 Gigabit Ethernet
top-of-rack switches that support both quad small form-factor pluggable (QSFP+), 100-Gbps QSFP+
(QSFP28) transceivers, and break out cables in the 32 QSFP28 sockets. The ports 0 through 31 can be
configured as either uplinks or as access ports. The QSFP28 ports are configured as 100-Gigabit Ethernet
ports by default, but can also be configured to speeds of 50, 40, 25, or 10-Gigabit Ethernet.
The QFX5200-32C and QFX5200-32C-L comes standard with redundant fans and redundant power
supplies. Switches can be ordered with either ports-to-FRUs or FRUs-to-ports airflow. The QFX5200-32C
is available with AC or DC power supplies; the QFX5200-32C-L is available only with AC power supplies.
Figure 1: QFX5200-32C Port Panel
The QFX5200-32C-L is supported as a standalone switch (Junos OS Evolved Release 18.3R1 and later).
The QFX5200-32C can be used as:
A standalone switch (Junos OS Release 15.1X53-D30 and later).
•
A member in an all QFX5200-32C Virtual Chassis (Junos OS Release 17.3R2 and later).
g050901
•
You can create an all QFX5200-32C Virtual Chassis with up to three members. The QFX5200-32C is
used in all three member roles: primary RE, backup RE, and line card.
A satellite device in a Junos Fusion Provider Edge system (Junos OS Release 18.1R2 and later). A switch
•
in standalone mode must be converted to a satellite device.
QFX5200-48Y Hardware
The QFX5200-48Y is a flexible switch for environments with the need for native 25 Gbps port speeds.
The 48 small form-factor pluggable 28 (SFP28) ports support 10 Gbps or native 25 Gbps speeds, and the
6 QSFP28 support either 40 Gbps or 100 Gbps speeds. The 48 SFP28 default to 10 Gigabit Ethernet and
must be configured in groups of four ports to support 25 Gigabit Ethernet. You can alternate each group
of four ports with either 10 Gbps or 25 Gbps across the 48 ports. For details on configuring the SFP28
ports, see “Port Groups” on page 30.
The 6 QSFP28 ports auto-detect the optic speed of transceivers and set the port speed accordingly. The
six QSFP28 ports can be channelized when configured to 40 Gigabit Ethernet to 4 independent 10 Gigabit
Ethernet ports.
20
The routing engine and control plane of the switch are driven by the 2.20 Ghz quad-core Intel CPU with
16 GB of memory and a 32 GB solid-state drive (SSD) for storage. The QFX5200-48Y provides an aggregate
throughput of 3.6 Tbps (full duplex).
As shown in Figure 2 on page 20, the QFX5200-48Y has a 1 U form factor and comes standard with
redundant fans and redundant power supplies. The switch can be ordered with either ports-to-FRUs or
FRUs-to-ports airflow and with AC or DCpower supplies.
The QFX5200-48Y is supported on Junos OS Release 18.1R1 and later.

21
Starting in Junos OS Evolved Release 18.3R1, ports can be channelized by configuration.
When the port is configured for 40-Gigabit Ethernet and a 4x10G breakout cable is detected, the system
•
converts the port into 4 independent 10-Gigabit Ethernet ports
When the port is configured for 100-Gigabit Ethernet and a 4x25G breakout cable is detected, the
•
system converts the port into 4 independent 25-Gigabit Ethernet ports
QFX5200-48Y Channelization
When one of the 6 QSFP28 ports are configured for 40-Gigabit Ethernet and a 4x10G breakout cable is
detected, the system converts the port into 4 independent 10-Gigabit Ethernet ports. Channelization is
not supported on the 48 SFP28 ports.
System Software
Customers who purchase a QFX5200-32C or QFX5200-48Y may either enable the Junos OS by purchasing
a Junos OS Base Services license. Customers purchasing a QFX5200-32C-L enable Junos OS Evolved by
purchasing a Junos OS Evolved Base Services license.
QFX Series devices use the Junos OS, which provides Layer 2 and Layer 3 switching, routing, and security
services. The Junos image is installed on one of the 32 GB solid state drives.The Junos OS Evolved software
running on the QFX5200-32C-L does not support Layer 2 features.
For more information about which features are supported on QFX Series devices, see Feature Explorer.

QFX5200 Component Redundancy
The following hardware components provide redundancy on a QFX5200 switch:
Power supplies—The QFX5200 switches have one or two power supplies. Each power supply provides
•
power to all components in the switch. 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.
Cooling system—The QFX5200-32C and QFX5200-32C-L switch models have five fan modules. The
•
QFX5200-48Y switch models has six fan modules. If a fan module fails and is unable to keep the QFX5200
switch within the desired temperature thresholds, chassis alarms occur and the QFX5200 switch can
shut down.
QFX5200 Field-Replaceable Units
24
Field-replaceable units (FRUs) are components that you can replace at your site. The QFX5200 device
FRUs are hot-insertable and hot-removable: you can remove and replace one of them without powering
off the switch or disrupting the switching function.
CAUTION: Replace a failed power supply with a new power supply within one minute
of removal to prevent chassis overheating. The switch 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 switch with
missing FRUs for longer than one minute.
Table 4 on page 24 lists the FRUs for the QFX5200 device and actions to take before removing them.

NOTE: If you have a Juniper Care service contract, register any addition, change, or upgrade of
hardware components at https://www.juniper.net/customers/support/tools/updateinstallbase/
. 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.

to provide either 40 Gigabit Ethernet or 4x10 Gigabit Ethernet speeds.
Channelizing Interfaces
For downstream traffic, the QFX5200-32C has 32 physical or 128 logical ports (32 x 4) that can be used
for port channelization. The 100 Gigabit Ethernet ports can be channelized using breakout cables either
to 2 independent downstream 50 Gigabit Ethernet or to 4 independent 25 Gigabit Ethernet ports. The
default 100 Gigabit Ethernet ports can also be configured as 40 Gigabit Ethernet and in this configuration
can either operate as dedicated 40 Gigabit Ethernet ports or can be channelized to 4 independent 10 Gigabit
Ethernet ports using breakout cables.
The QFX5200-32C ports support auto-channelization starting in Junos OS Release 15.1X53-D230.
The QFX5200-32C-L does not support channelization.
Network Port LEDs
27
The Link/Activity LED configuration for QFX5200-32C and QFX5200-32C-L switches use bi-colored
LEDs. The link LED indicates link activity or a fault. See Table 5 on page 27.
