QFX5200 Hardware Component Overview | 6
The QFX5200 line oers line-rate, low-latency 10/25/40/50/100GbE switches for building large IP
fabrics. QFX5200 Switches are an opmal choice for spine-and-leaf IP fabric deployments as well as
metro use cases.
This topic covers:
QFX5200 Hardware
QFX5200 line of switches oer compact 1 U models that provide a line rate conguraon packet
performance, very low latency, and a rich set of Layer 3 features.
2

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
conguraon packet performance, very low latency, and a rich set of Layer 3 features. The roung
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 Operang
System (OS); the QFX5200-32C-L models run Junos OS Evolved.
As shown in Figure 1 on page 3, 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
congured as either uplinks or as access ports. The QSFP28 ports are congured as 100-Gigabit
Ethernet ports by default, but can also be congured 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 airow. 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 only).
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).
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 exible switch for environments with the need for nave 25 Gbps port speeds.
The 48 small form-factor pluggable 28 (SFP28) ports support 10 Gbps or nave 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 congured 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
conguring the SFP28 ports, see "QFX5200-48Y Port Panel" on page 13.
The 6 QSFP28 ports auto-detect the opc speed of transceivers and set the port speed accordingly. The
six QSFP28 ports can be channelized when congured to 40 Gigabit Ethernet to 4 independent 10
Gigabit Ethernet ports.
The roung 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 4, 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 airow and with AC or DCpower supplies.
The QFX5200-48Y is supported on Junos OS Release 18.1R1 and later.
Figure 2: QFX5200-48Y Port Panel
Benets of QFX5200 Switches
QFX5200 switches oer:
• Future proof and investment protecon
• Open and standards based for mul-vendor networks
• Support for Zero Touch Provisioning (ZTP) for simplied operaon
4

QFX5200-32C Channelizaon
Starng in Junos OS Release 17.3R1, ports are channelized automacally by detecng the cable type.
The mode and number of channels are set based on the channel link status:
• When the port is congured 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 congured for 100-Gigabit Ethernet and a 2x50G breakout cable is detected, the
system converts the port into 2 independent 50-Gigabit Ethernet ports
• When the port is congured for 100-Gigabit Ethernet and a 4x25G breakout cable is detected, the
system converts the port into 4 independent 25-Gigabit Ethernet ports
QFX5200-32C-L Channelizaon
Starng in Junos OS Evolved Release 18.3R1, ports can be channelized by conguraon.
• When the port is congured 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 congured 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 Channelizaon
When one of the 6 QSFP28 ports are congured for 40-Gigabit Ethernet and a 4x10G breakout cable is
detected, the system converts the port into 4 independent 10-Gigabit Ethernet ports. Channelizaon is
not supported on the 48 SFP28 ports.
System Soware
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, roung, and
security services. The Junos image is installed on one of the 32 GB solid state drives.The Junos OS
Evolved soware running on the QFX5200-32C-L does not support Layer 2 features.
For more informaon about which features are supported on QFX Series devices, see Feature Explorer.
You manage the switch using the Junos OS command-line interface (CLI), accessible through the console
and out-of-band management ports on the device.

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 interrupon.
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 ve fan modules. The
QFX5200-48Y switch models has six fan modules. If a fan module fails and is unable to keep the
7

QFX5200 switch within the desired temperature thresholds, chassis alarms occur and the QFX5200
switch can shut down.
QFX5200 Field-Replaceable Units
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
o the switch or disrupng the switching funcon.
CAUTION: Replace a failed power supply with a new power supply within one minute
of removal to prevent chassis overheang. The switch connues 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 overheang. Do not operate the switch with
missing FRUs for longer than one minute.
Table 2 on page 8 lists the FRUs for the QFX5200 device and acons to take before removing them.
Table 2: FRUs in a QFX5200 Switch
FRU Required Acon
Power supplies None.
Fan modules None.
Opcal transceivers None. We recommend that you disable the interface using the set
interfaces interface-name disable command before you remove the
transceiver. See "Disconnect a Fiber-Opc Cable" on page 141
NOTE: If you have a Juniper Care service contract, register any addion, change, or upgrade of
hardware components at hps://www.juniper.net/customers/support/tools/updateinstallbase/ .
Failure to do so can result in signicant delays if you need replacement parts. This note does not
apply if you replace exisng components with the same type of component.

Channelizing Interfaces
For downstream trac, the QFX5200-32C has 32 physical or 128 logical ports (32 x 4) that can be used
for port channelizaon. 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 congured as 40 Gigabit Ethernet and in this
conguraon 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-channelizaon starng in Junos OS Release 15.1X53-D230.
The QFX5200-32C-L supports channelizaon by conguraon starng in in Junos OS Evolved Release
18.3R1.
