The Juniper Networks QFX10002 xed conguraon switch builds a strong underlay foundaon for
exible, high-performance, standards-based fabrics and roung that improve network reliability and
agility. As part of the QFX10000 line of switches, the QFX10002 models provide the exibility of 10-
Gbps, 40-Gbps, and 100-Gbps port speeds in a 2 U xed conguraon. For more informaon, see the

The Juniper Networks QFX10002 is a xed conguraon switch that oers a variety of port densies
and network port conguraons. This topic covers:
2

Benets of the QFX10002 Switch
• Combats applicaon latency by using a deep buer with hybrid memory cube (HMC) technology to
absorb network trac spikes. Deep buers 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 plaorm that can be posioned in mulples roles –data center, data center
interconnect, or data center edge, as well as campus and roung use cases because of its high logical
scale.
• Enables cloud providers to collapse mulple layer in the network (spine and data center interconnect)
that oer capital and operaonal expenditure savings.
• Saves on power with an opmized power prole per 100 Gigabit Ethernet.
QFX10002 Models
The QFX10002 line of switches are deep-buer xed-chassis switches in a 2 U form factor for xed
core and spine deployments. All models of the QFX10002 support port densies of 10 Gigabit Ethernet,
40 Gigabit Ethernet and 100 Gigabit Ethernet. In addion, all switches are available with either an AC or
DC power supply and with port to eld replaceable unit (FRU) cooling. This type of cooling is also known
as
airow out (AFO) or front-to-back cooling . The QFX10002 is available in three port conguraons:
• QFX10002-36Q
• QFX10002-72Q
• QFX10002-60C
The QFX10002-36Q oers 36 ports of 40-Gigabit Ethernet quad small-form factor plugable (QSFP+) or
12 ports 100-Gigabit Ethernet 28-Gbps QSFP+ Pluggable Soluon (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 4.

Figure 1: QFX10002-36Q Port Panel
The QFX10002-72Q oers 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 4.
Figure 2: QFX10002-72Q Port Panel
The QFX10002-60C oers exible conguraon of the 60 QSFP28 ports. Each port can be congured
as either 100 Gbps, 40 Gbps, or 4 by 10 Gbps. It has up to 12 Tbps of throughput and 4 Bpps of
forwarding capacity. The QFX10002-60C ships with four 1600 W AC or DC power supplies and three
fan modules. See Figure 3 on page 4.

QFX10002-36Q-DC 36 QSFP+ DC
The QFX10002 models feature PHY-less interfaces to save on power and to lower latency. The ports on
all models support quad small-form factor pluggable (QSFP+) transceivers and the 28-Gbps QSFP+
Pluggable Soluon (QSFP28) transceivers. The interfaces on a QFX10002 can be congured to support
10-Gbps, 40-Gbps, and 100-Gbps port speeds. See Table 2 on page 5.

System Architecture
The system architecture cleanly separates control operaons from packet forwarding operaons. This
design eliminates processing and trac bolenecks, perming the QFX10002 to achieve high
performance.
• Control operaons are performed by the Roung Engine, which runs the Juniper Networks Junos
operang system (Junos OS). The Roung Engine handles roung protocols, trac engineering,
policy, policing, monitoring, and conguraon management. Junos OS is installed on the QFX10002
internal solid-state drives (SSDs). QFX10002-36Q and QFX10002-72Q have 2 x 25-GB SSD and the
QFX10002-60C has 2 x 64-GB SSDs. The Roung Engine has a 2.5-GHz quad core Intel CPU and
has 16 GB of SDRAM on the QFX10002-36Q and QFX10002-72Q. There is 32 GB of SDRAM on
the QX10002-60C.
• Forwarding operaons are performed by the Packet Forwarding Engines, which include custom
ASICs designed by Juniper Networks. The Q5 ASICs enable the QFX10002 to provide up to
2.88 terabits per second (Tbps) of throughput on the QFX10002-36Q, 5.76 Tbps on the
QFX10002-72Q and 12 Tbps on the QFX10002-60C. The Q5 ASICs are connected to Hybrid
Memory Cubes (HMCs). These high-eciency memory modules provide packet buering, virtual
output queue (VOQ) memory, and improved logical system scale.
Cooling and Power
The cooling system in a QFX10002 consists of three 80-W fan modules that operate at 150 cubic feet
per minute (CFM) at full speed as well as fans housed in the power supplies. Each fan modules has dual
counter-rotang fans. These fan modules can be hot-swapped and hot-inserted, meaning that– you do
not need to power o the switch or disrupt the switching funcon to replace a module.
in the QFX10002 cooling system, cool air enters through the vents in the port panel and hot air
exhausts through the eld-replaceable unit (FRU) panel. This type of airow is known as
airow out or
port-to-FRU airow .
The four AC or DC 1600-W power supplies are installed by the factory in the QFX10002-72Q and
QFX10002-60C; two power supplies are installed in the QFX10002-36Q. See Figure 4 on page 7 for
an example of the QFX10002-72Q FRU panel. Each power supply provides 12 VDC output with a
standby voltage of 12-VDC.The AC or DC power supplies in a QFX10002 are hot-removable and hot-
insertable FRUs.

CAUTION: Mixing dierent types (AC and DC) of power supplies in the same chassis is
not supported.
The power supply bays on the QFX10002-72Q and QFX10002-36Q are numbered horizontally from
the top le to the boom right. The QFX10002-60C power supply bays are numbered vercally from
the top le to the boom right, which matches CLI output.
System Soware
QFX Series devices use the Junos operang system (OS), which provides Layer 2 and Layer 3 switching,
roung, and security services. Junos OS is installed on a QFX10002 switch’s 25-gigabyte (GB) internal
NAND solid state ash drive. The same Junos OS code base that runs on QFX10002 switches also runs
on all Juniper Networks EX Series switches, and M Series, MX Series, and T Series routers.
For more informaon about which features are supported on QFX Series devices, see Feature Tracker.
You manage the switch using the Junos OS command-line interface (CLI), which is accessible through
the console and out-of-band management ports on the device.
QFX10002 Hardware Component Overview
The QFX10002 supports the components in listed in alphabec order. See "QFX10002 Chassis Physical

QFX10002 Component Redundancy
The following hardware components provide redundancy on QFX10002 models:
• Power supplies
As shown in Table 4 on page 9, the QFX10002-72Q and QFX10002-60C can operate with a single
DC input power supply or a single AC input power supply for 220VAC operaon. A minimum of two
AC power supplies are required to operate the QFX10002-72Q and QFX10002-60C at 110VAC. The
QFX1002-36Q can operate with a single DC input power supply or it can operate with a single AC
power supply at 110VAC and 220VAC.
CAUTION: When running the switch in non-redundant mode, install a power supply
cover (QFX10002-PWR-BLNK) in any unused power bays for safety, cooling, and
emissions control.
8

The recommended conguraon is to run the switch with twice as much power as needed, also
called 2N , for full power redundancy. To provide addional power for switch redundancy or feed-
redundancy, see Table 4 on page 9.

• Cooling system—All models of the QFX10002 have three fan modules. Each fan module is a
redundant unit containing two fans. If a fan module fails and is unable to keep the QFX10002 within
the desired temperature thresholds, chassis alarms occur and the QFX10002 device might shut
down.
10

QFX10002 Field-Replaceable Units
Field-replaceable units (FRUs) are components that you can replace at your site. The QFX10002 FRUs
are hot-removable and hot-insertable: you can remove and replace them without powering o the
switch or disrupng the switching funcon.
CAUTION: Replace a failed fan module with a new fan module within one minute of
removal to prevent chassis overheang.
Table 5 on page 11 lists the FRUs for the QFX10002-72Q and acons to take before removing them.
