BenefitsoftheQFX10002Switch

•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 platform that can be positioned in multiples roles –data center, data center interconnect, or data center edge, as well as campus and routing use cases 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.

QFX10002Models

TheQFX10002lineofswitchesaredeep-bufferfixed-chassisswitchesina2Uformfactorforfixedcore 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 airflowout(AFO) or front-to-backcooling. 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).

SystemArchitecture

The system architecture cleanly separates control operations from packet forwarding operations. This designeliminatesprocessingandtrafficbottlenecks,permittingtheQFX10002toachievehighperformance.

•Control operations are performed by the Routing Engine, which runs the Juniper Networks Junos operating system (Junos OS). The Routing Engine handles routing protocols, traffic engineering, policy, policing, monitoring, and configuration management. Junos OS is installed on the QFX10002 internal solid-state drives (SSDs). QFX10002-36Q and QFX10002-72Q have 2 x 32-GB SSD and the QFX10002-60C has 2 x 64-GB SSDs. The Routing 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 operations 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-efficiency memory modules provide packet buffering, virtual output queue (VOQ) memory, and improved logical system scale.

CoolingandPower

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-rotating fans. These fan modules can be hot-swapped and hot-inserted, meaning that– you do not need to power off the switch or disrupt the switching function 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 field-replaceable unit (FRU) panel. This type of airflow is known as airflowout or port-to-FRU airflow.

The four AC or DC 1600-W power supplies are installed by the factory in the QFX10002-72Q and QFX10002-60C;twopowersuppliesareinstalledintheQFX10002-36Q. See Figure4onpage22 foran 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.

SystemSoftware

QFX Series devices use the Junos operating system (OS), which provides Layer 2 and Layer 3 switching, routing, and security services. Junos OS is installed on a QFX10002 switch’s 25-gigabyte (GB) internal NAND solid state flash 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 information about which features are supported on QFX Series devices, see Feature Tracker.

QFX10002ComponentRedundancy

The following hardware components provide redundancy on QFX10002 models:

•Power supplies

As shown in Table 6 on page 24, the QFX10002-72Q and QFX10002-60C can operate with a single DCinputpowersupplyorasingleACinputpowersupplyfor220VACoperation. AminimumoftwoAC power supplies are required to operate the QFX10002-72Q and QFX10002-60C at 110VAC. The QFX1002-36QcanoperatewithasingleDCinputpowersupplyoritcanoperatewithasingleACpower supply at 110VAC and 220VAC.

CAUTION: Whenrunningtheswitchinnon-redundantmode,installapowersupply cover (QFX10002-PWR-BLNK) in any unused power bays for safety, cooling, and emissions control.

The recommended configuration is to run the switch with twice as much power as needed, also called 2N,forfullpowerredundancy.Toprovideadditionalpowerforswitchredundancyorfeed-redundancy, see Table 6 on page 24.

•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.

QFX10002Field-ReplaceableUnits

Field-replaceableunits(FRUs)arecomponentsthatyoucanreplaceatyoursite.TheQFX10002FRUsare hot-removable and hot-insertable: you can remove and replace them without powering off the switch or disrupting the switching function.

CAUTION: Replace a failed fan module with a new fan module within one minute of removal to prevent chassis overheating.

Table 7 on page 26 lists the FRUs for the QFX10002-72Q and actions to take before removing them.

Overview

Any of the 36 ports 0 through 35 can be configured as either uplink or network ports. See Figure 6 on page 28.

2—Port panel with QSFP+ network interface or uplink ports (36)

The default configuration is independent 40-Gigabit Ethernet for all 36 ports. For 100-Gbps or 10-Gbps channelization operation, the ports operate within port groups. Every three ports compose a port group. See Table 8 on page 29 and Figure 7 on page 30 through Figure 10 on page 31.

Table8:QFX10002-36QPortCapacities
Per Port Group	Per Switch
1 x100 Gbps	12 x 100 Gbps
3 x 40 Gbps	36 x 40 Gbps
12 x 10 Gbps	144 x 10 Gbps

The second and sixth port in each 6XQSFP+ socket can be configured to support:

•100-Gigabit Ethernet using 28-Gbps QSFP28 optical transceivers and 100-Gbps active optical cables (AOCs). WhenaQSFP28transceiverisinsertedintotheportsmarkedwithafineblacklineunderneath thesocketandtheportisconfiguredfor100-GigabitEthernet,thetwoadjacentportsaredisabledand the QSFP28 is enabled for 100-Gigabit Ethernet.

•40-Gigabit Ethernet using QSFP+ optical transceivers or 40-Gbps direct attach copper (DAC) cables.

•10-GigabitEthernetusingDACbreakoutcables(DACBO).Whenconfiguredforchannelization,abreakout cable converts the 40-Gigabit Ethernet port into 4 independent 10-Gigabit Ethernet ports. The two adjacent QSFP+ ports in the port group are also configured for channelization at the same time. You cannot configure a single port for channelization.

NetworkPorts

Each of the 12 QSFP28 ports support:

•100-Gigabit Ethernet QSFP28 transceivers

•100-Gigabit Ethernet active optical cables (AOCs)

•40-Gigabit Ethernet QSFP+ transceivers

•40-Gigabit Ethernet QSFP+ DAC cables

•40-GigabitEthernetQSFP+to10-GigabitEthernetSFP+directattachcopperbreakout(DACBO)cables

The remaining ports support:

•40-Gigabit Ethernet QSFP+ transceivers

•40-Gigabit Ethernet QSFP+ DAC cables

•40-Gigabit Ethernet QSFP+ to 10-Gigabit Ethernet SFP+ DACBO cables

•10-Gigabit Ethernet SFP+ transceivers

•10-Gigabit Ethernet DAC cables

100-GbpsOperationandConfiguration

Every second and sixth port in a 6XQSFP cage on a QFX10002 supports 100-Gigabit Ethernet using QSFP28 transceivers. These 100-Gigabit Ethernet ports work either as 100-Gigabit Ethernet or as 40-Gigabit Ethernet, but are recognized as 40-Gigabit Ethernet by default. See Figure 7 on page 30 for a closeupviewofa6XQSFP+cage.The100-GigabitEthernetaredesignatedbyafineblacklineunderneath the port. See Figure 8 on page 30. When a 40-Gigabit Ethernet transceiver is inserted into a 100-Gigabit Ethernet port, the port recognizes the 40-Gigabit Ethernet port speed. However, when an 100-Gigabit Ethernet transceiver is inserted into the port, the transceiver is not automatically recognized and is not seenintheoutputoftheshowchassishardwarecommand.Toenable100-GigabitEthernetonthemarked ports, use the setchassisfpc command. For example, to enable port 11 for 100 Gbps speeds:

setchassisfpc0pic0port11speed100g

The port then recognizes the 100-Gigabit Ethernet speed and disables two adjacent 40-Gigabit Ethernet ports. See Figure 9 on page 31.
