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 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;

}

} }

xii

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]

xiii

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.

The QFX5100 line of 10/40GbE switches delivers low latency, flexible deployment options, and rich automation features. QFX5100 Switches build a strong underlay foundation for flexible, high-performance, standards-based fabrics and routing that improve network reliability and agility.

QFX5100 Hardware

QFX5100 line of switches offer two compact 1 U models and a 2 U model that provide wire-speed packet performance, very low latency, and rich set of Layer 2 and Layer 3 features. In addition to a high-throughput Packet Forwarding Engine, the performance of the control plane running on all the QFX5100 switches is enhanced by the 1.5 Ghz dual-core Intel CPU with 8 GB of memory and 32 GB of solid-state drive (SSD) storage.

The QFX5100-24Q-AA switch has a 2.5 GHz 4-core Intel CPU with 32 GB of memory and 128 GB of SSD storage.

The QFX5100 line of switches include both 10GE and 40GE fixed-configurations:

QFX5100-48S

•

As shown in Figure 1 on page 20, the QFX5100-48S is a 10-Gigabit Ethernet Enhanced Small Form-Factor Pluggable (SFP+) top-of-rack switch with 48 SFP+ ports and 6 Quad SFP+ (QSFP+) ports. Each SFP+ port can operate as a native 10 Gigabit port, when 10 Gbps optics are used. The SFP+ ports can also run at 1 Gbps, or at 100 Mbps speeds when 1_Gigabit optics are inserted. Each QSFP+ port (48 through

53) can operate as uplink ports or four QSFP+ port (50 through 53) can operate at native 40-Gigabit speed or as 4 independent 10-Gigabit port speeds. The 6 QSFP+ ports can be used as either access ports or as uplinks. The QFX5100-48S provides full duplex throughput of 1.44 Tbps. The QFX5100-48S 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 DC power supplies.

•

Pluggable (SFP+) or four 1-Gigabit Ethernet ports. See Figure 7 on page 25.

CAUTION: Use only the top four ports or the bottom four ports for SFP

transceivers. Because SFP transceivers are larger than SFP+ transceivers, attempting to stack SFP transceivers can cause internal damage to the module.

Figure 7: EX4600-EM-8F Expansion Module

NOTE: The EX4600-EM-8F is not supported on the QFX5100-24Q running in QFabric

systems.

The QFX5100-24Q is configured for the QFX-EM-4Q by default, but any combination of the two modules is supported. Expansion modules can be hot-inserted or hot-removed. However, when an EX4600-EM-8F is inserted instead of the default QFX-EM-4Q, the new configuration causes the interfaces to temporarily go down. Likewise, when an EX4600-EM-8F is running on the QFX5100-24Q and it is swapped with a QFX-EM-4Q, the interfaces temporarily go down, which can cause a short disruption in traffic.

QFX5100-24Q-AA

•

As shown in Figure 8 on page 26, the QFX5100-24Q-AA is a 1 U, top-of-rack, 40-Gigabit Ethernet QSFP+ switch with 24 high-density QSFP+ ports. Each QSFP+ port can be configured to support 40-Gigabit Ethernet or as a set of 4 independent 10-Gigabit Ethernet ports. The QFX5100-24Q-AA can also be configured to support twenty-four 40-Gigabit Ethernet interfaces or ninety-six 10-Gigabit Ethernet interfaces using breakout cables (channelization mode) with 1280 Gbps output. The switch can be ordered with either ports-to-FRUs or FRUs-to-ports airflow and with AC or DC power supplies. The QFX5100-24Q switch provides full duplex throughput of 2.56 Tbps.

The QFX5100-24Q-AA module bay can accommodate a single Packet Flow Accelerator (PFA) double-wide expansion module (QFX-PFA-4Q) or two single-wide optional expansion modules (two or one each of QFX-EM-4Q and EX4600-EM-8F). The QFX-PFA-4Q, which features a high-performance field-programmable gate array (FPGA), provides four additional QSFP+ ports to the chassis. Each QFX-EM-4Q adds four QSFP+ ports to the chassis and each EX4600-EM-8F adds eight 10-Gigabit SFP+ ports to the chassis. The QFX-EM-4Q ports can also be configured as either access ports or uplink ports, but only ports 0 and 2 can be channelized using port mode. For full details on the different port channelization modes, see “Port Panel of a QFX5100-24Q Device” on page 34. All ports on the QFX5100-24Q and QFX-EM-4Q can be configured as either access ports or uplink ports.

This switch provides the hardware support to enable PTP boundary clocks by using the QFX-PFA-4Q module. The QFX5100-24Q-AA also supports GPS in and out signals when QFX-PFA-4Q is installed.

The CPU subsystem of this switch includes a 2-port 10-Gigabit Ethernet network interface card (NIC) to provide a high bandwidth path or to alternate traffic path to guest VMs directly from the Packet Forwarding Engine.

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 QFX5100 switch’s 32-gigabyte (GB) internal solid state flash drive. The same Junos OS code base that runs on QFX5100 switches also runs on all Juniper Networks EX Series switches, M Series, MX Series, and T Series routers.

Participation in a QFX5110 Virtual Chassis or a QFX5110 VCF requires the same Junos OS image on all devices in the Virtual Chassis or VCF. Junos OS 17.3R1 or later is the minimum software release for QFX5110 Virtual Chassis or QFX5110 VCF.

For more information 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.

Understanding Hardware Redundancy of QFX5100 Device Components and Functionality

The following hardware components provide redundancy on a QFX5100 switch:

Power supplies—The QFX5100 switch has 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 1 U models of QFX5100 line of switches have five fan modules; the 2 U

•

QFX5100-96S has three fan modules. If a fan module fails and is unable to keep the QFX5100 switch within the desired temperature thresholds, chassis alarms occur and the QFX5100 switch can shut down.

SEE ALSO

QFX5100 Power System | 64 QFX5100 Cooling System | 75

Field-Replaceable Units in a QFX5100 Device

Field-replaceable units (FRUs) are components that you can replace at your site. The QFX5100 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 blank panel or 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 32 lists the FRUs for the QFX5100 device and actions to take before removing them.

Switch Ports

The QFX5100-24Q device ports, (0 through 23) support:

40 Gbps QSFP+ transceivers

•

QSFP+ to QSFP+ direct attach copper (DAC) cables

•

QSFP+ to SFP+ direct attach copper break out (DACBO) cables

•

QSFP+ to QSFP+ active optical cables (AOC)

•

QSFP+ to SFP+ active optical breakout cable (AOCBO)

•

Access ports

•

You can use 40-Gigabit Ethernet QSFP+ transceivers and QSFP+ direct attach copper cables in any downstream port. See “Determining Interface Support for the QFX5100 Device” on page 98.

Uplink ports

•

You can configure up to 4 of the 40 GbE ports as uplinks. Each additional QFX-EM-4Q, Expansion Module adds the switch uplink capacity by 2 for a total of 8 uplinks.

To connect a QFX5100-24Q switch as a Node device in a QFabric system, you need:

Four QSFP+ uplink ports on each QFX5100-24Q Node device to connect to the data plane network

•

through the QFX3008-I or QFX5100-24Q Interconnect devices.

Two additional QSFP+ uplink ports on each QFX5100-24Q Node device connect to the data plane

•

network through the QFX3008-I or QFX5100-24Q Interconnect devices. .

QFabric Systems

The QFX5100-24Q operates as a Node device in both the QFX3000-G and QFX3000-M QFabric systems. Additionally, the QFX5100-24Q can be configured as an Interconnect Device in QFX3000-M QFabric systems allowing a maximum of 16 Node devices. The QFX5100-24Q may not be mixed with QFX3600-I Interconnect devices in the same QFabric system.

When operating as a Node device, ports 0 through 7 are default FTE ports; ports 8 through 15 can be configured as either uplink (FTE) or access ports (XLE). In the port range 8 through 23, only 12 ports can be channelized when the 2 QFX-EM-4Q are installed.

NOTE: The EX4600-EM-8S expansion module is not supported on the QFX5100-24Q device

in a QFabric system.

Channelizing Interfaces (Non-QFabric)

When fully populated with 2 QFX-EM-4Q Expansion Modules, the QFX5100-24Q device has 128 physical ports. However, only 104 logical ports can be used for port channelization. Depending on the system mode you configure for channelization, different ports are restricted. If you attempt to channelize a restricted port, the configuration is ignored. The following system modes are available on the QFX5100-24Q device:

Default mode

•

All 24 QSFP+ ports on the switch (PIC 0) are channelized by default (96 ports). With QFX-EM-4Q Expansion Modules (PIC 1) and (PIC 2), the QSFP+ ports are supported for access or uplink ports, but cannot be channelized. Ports are over-subscribed In this mode and could be subject to packet-loss. You can have one of two port combinations: 32 40-Gbps QSFP+ ports, or 96 10-Gigabit Ethernet ports plus 8 40-Gbps QSFP+ ports.

104 port mode

•

All 24 QSFP+ ports on the switch (PIC 0) are channelized (96 ports). Two ports on QFX-EM-4Q Expansion Module (PIC 1) are also channelized (8 additional). In this mode, ports 0 and 2 are channelized by default and ports 1 and 3 are disabled. If additional QSFP+ ports are detected in an expansion module (PIC 2), those ports are ignored.

Flexi-pic mode

•

Ports 0 through 3 of the switch cannot be channelized; ports 4 through 24 are channelized by default (80 ports). With QFX-EM-4Q Expansion Modules (PIC 1) and (PIC 2), the QSFP+ ports are supported for access or uplink ports, but cannot be channelized. With EX4600-EM-8F Expansion Modules installed (PIC 1) and (PIC 2), the 16 SFP+ ports of SFP are recognized for a total of 96 logical ports.

Non-oversubscribed mode

•

All 24 QSFP+ ports on the switch (PIC 0) are channelized (96 ports). Expansion modules on PIC 1 and PIC 2 are not supported and cannot be channelized. There is no packet loss for packets of any size in this mode.

Virtual Chassis and Virtual Chassis Fabric

The QFX5100-24Q device operates as a standalone switch, a member of a QFX Virtual Chassis, or as a spine or leaf device in a QFX5100 Virtual Chassis Fabric (VCF). QFX Virtual Chassis support up to 10 members. QFX5100 VCF supports 20 QFX5100 and EX4300 devices, of which 4 QFX5100 devices can be configured as spines.

To connect a QFX5100-24Q device as a member in a QFX Virtual Chassis, you need to cable a pair of ports to link each member in the Virtual Chassis into a ring topology. Each member in the ring has at least one direct Virtual Chassis port (VCP) connection to each directly connected member. QFX5100-24Q devices are recommended in the primary, backup, or line card role. When mixed with QFX3500 or QFX3600 devices, configure the QFX5100-24Q device in the primary and backup roles. See “Connecting QFX Series

and EX Series Switches in a QFX Virtual Chassis” on page 127 for cabling diagrams. The Virtual Chassis

feature is not applicable to QFX devices in a QFabric.

To connect a QFX5100-24Q device as a spine or leaf device in a QFX5100 VCF, you need to cable a set of ports as VCP connections that link each spine device and leaf device. All spine devices have at least one direct VCP connection to each leaf device in the VCF. Non-channelized DAC cables can be configured as VCP connections. See “Connecting a QFX5100 Device in a Virtual Chassis Fabric” on page 134 for a cabling diagram.

BEST PRACTICE: Whenever possible use the QFX5100-24Q device as a spine device. By using

the QFX5100-24Q device in a maximum configuration of 20 total devices, four QFX5100-24Q devices may be used as spine devices. All members can be connected to the spine using QSFP+ ports.

As of Junos OS release 17.3R1, you can also connect a QFX5100-24Q as a leaf device in a QFX5110 VCF or as a member in a QFX5110 Virtual Chassis.

Port Panel of a QFX5100-24Q-AA Device

The port panel of the QFX5100-24Q-AA switch consists of 24 quad small-form factor pluggable plus (QSFP+) 40-Gigabit Ethernet ports. Each QSFP+ socket can be configured to support 40-Gigabit Ethernet or as a set of four independent 10-Gigabit Ethernet ports using breakout cables (channelization mode). The QFX5100-24Q-AA can also be configured to support 96 10-Gigabit Ethernet ports using breakout cables (channelization mode) with 1280 Gbps output. Any of the 24 ports can be configured as either an uplink port or an access port.

The expansion module bay of the QFX5100-24Q switch is located on the port panel. In the expansion module bay, you can install a single double-wide expansion module (QFX-PFA-4Q) or two single-wide optional expansion modules (QFX-EM-4Q and EX4600-EM-8F, in any combination). When you install two single-wide expansion modules, the slot on your left hand side is slot 1 (QIC0), and the slot on your right hand side is slot 2 (QIC1).

The QFX-PFA-4Q module adds four QSFP+ ports to the chassis. The QFX-EM-4Q module adds four QSFP+ ports to the chassis and the EX4600-EM-8F module adds eight 10-Gigabit SFP+ ports to the chassis. The QFX-EM-4Q ports can be configured as either access ports or as uplinks ports, but only ports 0 and 2 can be channelized by using port mode. The QFX-EM-4Q ports can also be configured as either access ports or uplink ports, but only ports 0 and 2 can be channelized by using port mode. Figure 13 on page 39 shows the port panel of the QFX5100-24Q-AA device.

Port Panel of QFX5100-48S and QFX5100-48SH Devices

The port panel of the QFX5100-48S and QFX5100-48SH switches supports up to a maximum of 72 logical 10 GbE ports when operating as a standalone switch. Forty-eight physical ports(0 through 47) support 10 Gigabit Ethernet small form-factor pluggable plus (SFP+) transceivers. These ports can also support 1 Gigabit SFP transceivers and can be configured at either 1 Gbps or 1 Gbps speeds using the set interface speed

command. All 48 of these ports can be used for SFP+ transceivers or SFP+ direct attach copper (DAC) cables. You can use 1-Gigabit Ethernet SFP+, 10-Gigabit Ethernet SFP+ transceivers and SFP+ DAC cables in any access port.

The remaining 24 logical ports are the six 40 GbE physical ports (48 through 53) that support up to 6 quad small-form factor pluggable plus (QSFP+) transceivers . Each QSFP+ socket can operate either as a single 40 Gbps port or as a set of 4 independent 10 Gbps ports using QSFP+ breakout cables. The 40 GbE ports can be configured as either access ports or as uplinks.

CAUTION: Do not install 1GbE copper transceivers (such as QFX-SFP-1GE-T) directly

above or below another 1GbE copper transceiver. Use only the top row or bottom row to avoid damage to the device caused by some types of copper transceivers when the transceivers are installed above or below each other. However, if you are using copper transceivers with the OEM part number FCLF8521P2BTL-J1 printed on the transceiver label, you can install the transceivers in any port with no restrictions. For devices that support 10GbE copper transceivers, there is no similar restriction.

To connect a QFX5100-48S switch as a node device in a QFabric system, you need:

Four QSFP+ uplink ports on each QFX5100-48S Node device to connect to the data plane network

•

through the QFX3008-I or QFX5100-24Q Interconnect devices.

The two remaining QSFP+ uplink ports on each QFX5100-48S Node device connect to the data plane

Support for the QFX5100 Device” on page 98.

To connect a QFX5100-48S switch as a member in a QFX Virtual Chassis, you need a pair of dedicated ports and cables that link each member in the Virtual Chassis into a ring topology. Each member in the ring has at least one direct Virtual Chassis port (VCP) connection to a upstream and downstream member. QFX5100-48S switches are recommended in the primary, backup, or line card role. When mixed with QFX3500 or QFX3600 devices, configure the QFX5100-48S in the primary and backup roles. See

“Connecting QFX Series and EX Series Switches in a QFX Virtual Chassis” on page 127 for cabling diagrams.

To connect a QFX5100-48S switch as a spine or leaf device in a QFX5100 Virtual Chassis Fabric (VCF), you need a pair of dedicated ports and cables that link each spine device and leaf device in the VCF. All spine devices have at least one direct VCP connection to each leaf device in the VCF. See “Connecting a

QFX5100 Device in a Virtual Chassis Fabric” on page 134 for a cabling diagram.

BEST PRACTICE: In a mixed QFX5100 VCF environment with multiple models of QFX5100 and

the EX4300, use QFX5100-24Q as spine devices. In the maximum configuration of 20 total devices, up to four QFX5100-24Q devices may be used as spine devices. All members can be connected to the spine using QSFP+ ports. You can configure the QFX5100-96S as a spine in an all QFX5100-96S VCF or in a mixed VCF comprised of EX4300 and QFX5100-96S.

CAUTION: Do not install 1GbE copper transceivers (such as QFX-SFP-1GE-T) directly

Channelizing Interfaces

The port panel of the QFX5100-96S switch supports up to a maximum of 104 logical 10 GbE ports that can be distributed over 96 small form-factor pluggable plus (SFP+) and 8 quad small-form factor pluggable plus (QSFP+) transceivers . Because of an 104 port restriction, only two of the eight QSFP+ can be channelized. Depending on how you set the system mode for channelization, the behavior of channelization for the QSFP+ changes. The following system modes are available for the QFX5100-96S switch:

Non-oversubscribed

•

All 96 SFP+ ports on the switch (PIC 0) are supported. In this mode, the eight QSFP+ ports are not supported and cannot be channelized. There is no packet loss for packets of any size in this mode.

Default mode

•

All 96 SFP+ ports on the switch (PIC 0) are supported. QSFP+ ports 96 and 100 can be channelized. If ports 96 and 100 are channelized, the interfaces on ports 97, 98, 99, 101, 102, and 103 are disabled.

Virtual Chassis and Virtual Chassis Fabric Support

The QFX5100-96S switch operates as a standalone switch, as a member in a QFX Virtual Chassis, as a member in a QFX5110 Virtual Chassis, as a spine or leaf device in a QFX5100 Virtual Chassis Fabric (VCF), or as a leaf device in a QFX5110 VCF. QFX Virtual Chassis support up to 10 members; QFX5100 VCF supports a total of 20 devices, of which 4 QFX5100 devices can be configured as spines. A QFX Virtual Chassis is cabled in a ring topology, where a VCF is cabled in a spine and leaf topology.

Virtual Chassis

In a QFX Virtual Chassis, you can connect up to 10 standalone QFX5100-96S switches into a QFX Series Virtual Chassis and manage the interconnected switches as a single chassis. The advantages of connecting multiple switches into a Virtual Chassis include better-managed bandwidth at a network layer, simplified configuration and maintenance because multiple devices can be managed as a single device, increased fault tolerance and high availability (HA) because a Virtual Chassis can remain active and network traffic can be redirected to other member switches when a single member switch fails, and a flatter, simplified Layer 2 network topology that minimizes or eliminates the need for loop prevention protocols such as Spanning Tree Protocol (STP).

As of Junos OS release 17.3R1, you can also connect a QFX5100-96S as a member in a QFX5110 Virtual Chassis.

Virtual Chassis Fabric

The VCF provides a low-latency, high-performance fabric architecture that can be managed as a single device. VCF is an evolution of the Virtual Chassis feature, which allows you to interconnect multiple devices into a single logical device, inside of a fabric architecture. The VCF architecture is optimized to support small and medium-sized data centers that contain a mix of 1-Gpbs, 10-Gpbs, and 40-Gbps Ethernet interfaces.

A VCF is constructed using a spine-and-leaf architecture and topology. In the spine-and-leaf architecture, each spine device is interconnected to each leaf device. A VCF supports up to 20 devices, of which 4 QFX5100 devices can be configured into spine devices. In a mixed environment with QFX5100-24Q, QFX5100-98S and EX4300, use the QFX5100-24Q as the spine device and the QFX5100-96S and EX4300 as a leaf devices. You may use the QFX5100-96S as a spine in an all QFX5100-96S VCF or in a VCF that has a mixture of QFX5100-96S and EX4300.

As of Junos OS release 17.3R1, you can also connect a QFX5100-24Q as a leaf device in a QFX5110 VCF.

Expansion Modules for QFX5100 Devices

IN THIS SECTION

EX4600-EM-8F | 47

QFX-EM-4Q | 49

QFX-PFA-4Q | 50

The QFX5100-24Q and QFX5100-24Q-AA devices have two bays on the port panel for optional expansion modules. These expansion modules can be hot-inserted or hot-removed. Expansion modules and transceivers are not shipped with the switch and must be ordered separately.

The QFX5100-24Q and QFX5100-24Q-AA support these expansion modules up to the 104-port limitation:

Two EX4600-EM-8F, which provides a total of 16 additional 10-Gigabit Ethernet Enhanced Small

•

Form-Factor Pluggable (SFP+) ports or 8 additional 1-Gigabit SFP ports. When both bays (PIC 1 and PIC 2) are populated with EX4600-EM-8F modules, you must configure the system mode as Flexi-pic. In this mode, port 0 to 3 of PIC 0 are disabled, which allows the devices to operate within the 104-port limitation.

Two QFX-EM-4Q, which provides a total of 8 additional 40-Gigabit Quad SFP+ (QSFP+) ports.

•

One EX4600-EM-8F and one QFX-EM-4Q, which provides 8 additional 10-Gigabit Ethernet SFP+ (or

•

8 additional 1-Gigabit SFP ports) and 4 additional 40-Gigabit (QSFP+) ports. This combination requires the system mode to be configured as Flexi-pic. See Configuring the System Mode.

Additionally, the QFX5100-24Q-AA supports the QFX-PFA-4Q expansion module, which provides 4 additional QSFP+ ports.

NOTE: In order to run the orchestration diagnostics, Precision Time Protocol (PTP) and

synchronization diagnostics, and utilities contained in the Packet Flow Accelerator Diagnostics software, you must have Junos OS Release 14.1X53-D27 or later software with enhanced automation installed on your QFX5100-24Q-AA.

EX4600-EM-8F

The EX4600-EM-8F is a MACsec-capable expansion module that inserts into one of the device bays of a QFX5100-24Q, QFX5100-24Q-AA, or an EX4600 switch. It provides 8 additional 10-Gigabit Ethernet

SFP+ ports or 8 additional 1-Gigabit SFP ports to each bay. Figure 17 on page 48 shows the ports and LEDs on the expansion module.

CAUTION: Copper SFP transceivers (1000BASE-T) are restricted to the top four ports

or the bottom four ports; fiber SFP transceivers (1000BASE-X) can be used in any of the eight ports. Attempting to stack copper SFP transceivers causes internal damage to the module.

Figure 17: EX4600-EM-8F Faceplate and LEDs

2—1— SFP+ port LEDsExpansion module status LED

When the expansion module is inserted into the expansion bay, the chassis detects the additional ports, recognizes them as 10GbE ports, and lights the Status LED. The QFX5100-24Q device is configured for the QFX-EM-4Q by default, but any combination of the two modules is supported. Expansion modules can be hot-inserted or hot-removed. However, when an EX4600-EM-4Q is inserted instead of the default QFX-EM-4Q, the Packet Forwarding Engine reboots that can cause some temporary disruption in traffic. See Configuring the System Mode.

NOTE: MACsec is supported on the 10-Gigabit Ethernet ports with the EX-QFX-MACSEC-AGG

license.

AC Power Supply for a QFX5100 Device

The two power supplies in QFX5100 switches are hot-removable and hot-insertable field-replaceable units (FRUs). The power supplies are installed in the switch at the factory. You can install replacement power supplies from the management panel without powering off the switch or disrupting the switching function.

The AC power supply in 1 U QFX5100 switches is 650 W; the AC power supply in the 2 U, QFX5100-96S switch, is 850 W. Both power supplies look identical. Be sure to use the correct power supply for your chassis product SKU (see Table 15 on page 66).

CAUTION: Do not mix power supplies with different airflow or different wattage. The

system raises an alarm when a power supply having a different airflow or wattage is inserted into the chassis.

See Figure 26 on page 65 for an example of the 1 U design and Figure 27 on page 65 for an example of the 2 U power supply.

4—2— Ejector leverSecurity latch

Figure 27: 2 U AC Power Supply in a QFX5100-96S Switch

The power supply provides FRU-to-port or port-to-FRU airflow depending on the product SKU you purchase. On legacy switches, or switches with an LCD, this airflow is called back-to-front and front-to-back. The power supplies have color-coded handles with a fan icon. See Figure 28 on page 66 for an example of the power supply. A power supply with a blue handle denotes FRU-to-port airflow; a power supply with a gold-colored handle denotes port-to-FRU airflow.

Figure 28: Power Supply Handle Detail

1—Fan icon on handle

CAUTION: Verify that the airflow direction on the power supply handle matches the

direction of airflow in the chassis. Ensure that each power supply you install in the chassis has the same airflow direction. If you install power supplies with two different airflow directions, Junos OS raises an alarm. If you need to convert the airflow pattern on a chassis, you must change out all the fans and power supplies at one time to use the new direction.

Table 15 on page 66 shows the different power supplies and their direction of airflow.

Fan Module Status | 81

The cooling system in an QFX5100 device consists of fan modules and a single fan in each power supply. The number of fan modules vary depending whether the size of the switch is 1 U or 2 U high. All switches can be set up to work in one of two airflow directions:

Airflow In–Air comes into the switch through the vents in the field-replaceable units (FRUs)

•

Airflow Out–Air comes into the switch through the vents in the port panel.

•

CAUTION: Airflow In and Airflow Out fans and power supplies cannot be mixed in

the same chassis.

Fan Modules

The fan modules in QFX5100 devices are hot-insertable and hot-removable field-replaceable units (FRUs). These fan modules are designed for one of the two available airflow directions (Airflow In or Airflow Out). Some fan modules are also color-coded for the airflow direction as well. The fan modules are installed in the fan module slots on the management panel of the switch next to the power supplies.

Both the 1 U and 2 U versions of QFX5100 fan modules have a similar design with different dimensions. The 1 U QFX5100 devices have 5 fan modules numbered 0 through 4 from left to right, where the 2 U, QFX5100-96S device, has 3 fan modules numbered 0 through 2. On all QFX5100 devices, each fan module slot has a fan icon next to it.

Figure 35 on page 76 shows the 1 U fan module and Figure 36 on page 77 shows the 2 U fan module.

Figure 35: 1 U Fan Module Used in QFX5100 Switches

Figure 36: 2 U Fan Module Used in QFX5100-96S Switches

g050311

You remove and replace a fan module from the FRU end of the chassis. The switch continues to operate for a limited period of time (30 seconds) during the replacement of the fan module without thermal shutdown.

NOTE: All fan modules must be installed for optimal operation of the switch.

The fan modules are available in two product SKUs that have different airflow directions—FRU-to-port airflow, indicated on some units by the azure blue color or a label. FRU-to-port airflow versions of the fan module that have labels are marked AIR IN . Likewise, port-to-FRU airflow is indicated by either a gold color or the label AIR OUT . On legacy switches or switches with LCDs, this airflow is also called front-to-back and back-to-front. Table 21 on page 78 lists the available fan module product SKUs and the direction of airflow in them:

Do not mix power supplies with different airflow. If the power supplies are color-coded, ensure they are either all azure blue for airflow in models or all gold for airflow out models. If the power supplies are not color-coded but have a label, ensure that the chassis is either using all airflow in ( AFI ) or all airflow out (AFO). Likewise, ensure that all fan modules have the same airflow and match the airflow of the power supplies. Fan modules are also either color-coded azure blue for airflow in or gold for airflow out. If the fan module has a label instead of being color-coded, ensure that labels (AIR IN and AIR OUT ) are not mixed. If the fan modules have AIR IN labels, the power supplies must also have AIR IN labels; if the fan modules have AIR OUT labels, the power supplies must also have AIR OUT labels.

Mixing components with different airflows in the same chassis hampers the performance of the cooling system of the switch and leads to overheating of the chassis.

CAUTION: The system raises an alarm if a fan module fails or if the ambient

temperature inside the chassis rises above the acceptable range. If the temperature inside the chassis rises above the threshold temperature, the system shuts down automatically.

Do not mix fan modules with different wattage. Only use the replacement fan modules that are designed for use with your product number. See Table 21 on page 78 for the correct part number for your QFX5100 device.

CAUTION: Do not mix AC and DC power supplies in the same chassis.

However if you need to convert a QFX5100 device to have a different airflow, you can change the airflow pattern. To convert an AIR IN product SKU to an AIR OUT product SKU or an AIR OUT product SKU to a AIR IN product SKU, you must replace all of the fans and power supplies at one time to use the new direction. The system raises an alarm when the system is converted, which is normal.

Fan Module Status

You can check the status of fan modules through the show system alarms command or by looking at the LEDs next to each fan module.

Each switch has a Status LED (labeled ST) for each fan module on the left side of the corresponding fan module slot. It indicates the status of all the fan modules. Table 22 on page 81 describes the Status LED on the fan module in a QFX5100 device.

Table 22: Fan Module LED

DescriptionLED State

Solid Green

The individual fan module is present. After the hardware senses the fan module, software ensures the airflow is consistent with the other fan modules and that it is functioning correctly.

Blinking Amber

Indicates one of the following:

The fan module is not present.

•

The fan module is not functioning normally.

•

Under normal operating conditions, the fan modules operate at a moderate speed. Temperature sensors

in the chassis monitor the temperature within the chassis.

The system raises an alarm if a fan module fails or if the ambient temperature inside the chassis rises above the acceptable range. If the temperature inside the chassis rises above the threshold temperature, the system shuts down automatically.

An error has been detected in the fan module. Replace the fan module as soon as possible. Either the fan has failed or it is seated incorrectly. To maintain proper airflow through the chassis, leave the fan module installed in the chassis until you are ready to replace it.

Clearance Requirements for Airflow and Hardware Maintenance for a QFX5100 Device

When planning the site for installing a QFX5100 device, you must allow sufficient clearance around the installed chassis (see Figure 42 on page 83).

Figure 42: Clearance Requirements for Airflow and Hardware Maintenance for a QFX5100 Device

For the cooling system to function properly, the airflow around the chassis must be unrestricted. See

•

“Cooling System and Airflow in a QFX5100 Device” on page 75 for more information about the airflow

through the chassis.

If you are mounting a QFX5100 device in a rack or cabinet with other equipment, ensure that the exhaust

•

from other equipment does not blow into the intake vents of the chassis.

Leave at least 24 in. (61 cm) both in front of and behind the QFX5100 device. For service personnel to

•

remove and install hardware components, you must leave adequate space at the front and back of the switch. NEBS GR-63 recommends that you allow at least 30 in. (76.2 cm) in front of the rack or cabinet and 24 in. (61 cm) behind the rack or cabinet.

To reduce or eliminate RFI from your site wiring, do the following:

Use a twisted-pair cable with a good distribution of grounding conductors.

•

If you must exceed the recommended distances, use a high-quality twisted-pair cable with one

•

ground conductor for each data signal when applicable.

If your site is susceptible to problems with electromagnetic compatibility (EMC), particularly from lightning or radio transmitters, seek expert advice.

Some of the problems caused by strong sources of electromagnetic interference (EMI) are:

Destruction of the signal drivers and receivers in the device

•

Electrical hazards as a result of power surges conducted over the lines into the equipment

•

Grounding Cable and Lug Specifications for a QFX5100 Device

For installations that require a separate grounding conductor to the chassis, the switch must be adequately grounded before power is connected to ensure proper operation and to meet safety and electromagnetic interference (EMI) requirements. To ground a QFX5100 device, connect a grounding cable to earth ground and then attach it to the chassis grounding points.

WARNING: The switch is pluggable type A equipment installed in a restricted-access

location. It has a separate protective earthing terminal provided on the chassis in addition to the grounding pin of the power supply cord. This separate protective earthing terminal must be permanently connected to earth ground for installations that require a separate grounding conductor to the chassis.

WARNING: To comply with GR-1089 requirements, all intra-building copper cabling

used for SFP+ and QSFP+ ports must be shielded and grounded at both ends.

CAUTION: Before switch installation begins, a licensed electrician must attach a cable

lug to the grounding cables that you supply. See “Connecting Earth Ground to a

QFX5100 Device” on page 138. A cable with an incorrectly attached lug can damage

the switch.

Before connecting the switch to earth ground, review the following information:

A protective earthing terminal bracket is provided in the accessory kit for connecting the switch to earth

•

ground. This L-shaped bracket attaches to the side of the QFX5100 chassis through the mounting bracket, providing a protective earthing terminal for the switch.

The grounding lug required is a Panduit LCD10-10A-L or equivalent (not provided).. The grounding lug

•

should accommodates 14–10 AWG (2–5.3 mm²) stranded wire.

The grounding cable that you provide for a QFX5100 device must be 14 AWG (2 mm²), minimum 60°

•

C wire, or as permitted by the local code.

Ensure you have two SAE 10-32 washers and screws to attach the cable and bracket (not provided).

•

Mounting bracket hole spacing

•

Rack size and strength

•

Table 27 on page 93 provides the rack requirements and specifications for the QFX5100 device.

Table 27: Rack Requirements for the QFX5100 Device

GuidelinesRack Requirement

Rack type (all product SKUs)

Rack type (QFX5100-96S only)

Mounting bracket hole spacing (all product SKUs)

Rack size and strength (all product SKUs)

Use a four-post rack that provides bracket holes or hole patterns spaced at 1 U (1.75 in. or 4.45 cm) increments and that meets the size and strength requirements to support the weight.

A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310–D) published by the Electronics Industry Association.

Use a two-post or four-post rack that provides bracket holes or hole patterns spaced at 1 U (1.75 in. or 4.45 cm) increments and that meets the size and strength requirements to support the weight.

The holes in the mounting brackets are spaced at 1 U (1.75 in. or 4.45 cm), so that the switch can be mounted in any rack that provides holes spaced at that distance.

Ensure that the rack complies with the standards for a 19-in. or 23-in. rack as defined

•

in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310–D) published by the Electronics Industry Association.

A 600-mm rack as defined in the four-part Equipment Engineering (EE); European

•

telecommunications standard for equipment practice (document numbers ETS 300 119-1 through 119-4) published by the European Telecommunications Standards Institute.

The horizontal spacing between the rails in a rack that complies with this standard is usually wider than the device's mounting brackets, which measure 19 in. (48.26 cm) from outer edge to outer edge. Use approved wing devices to narrow the opening between the rails as required.

Ensure that the rack rails are spaced widely enough to accommodate the switch chassis’

•

external dimensions. The outer edges of the front-mounting brackets extend the width to 28.5 in. (72.4 cm) to 31.5 in. (80 cm).

For four-post installations, the front and rear rack rails must be spaced between 28.5

•

in. (72.4 cm) to 31.5 in. (80 cm) front-to-back.

The rack must be strong enough to support the weight of the switch.

•

Ensure that the spacing of rails and adjacent racks allows for proper clearance around

•

the switch and rack.

Table 28: Cabinet Requirements for the QFX5100 Device

GuidelinesCabinet Requirement

Cabinet size and clearance

The minimum cabinet size for accommodating a QFX5100 device is 36 in. (91.4 cm) deep. Large cabinets improve airflow and reduce the chance of overheating.

Table 28: Cabinet Requirements for the QFX5100 Device (continued)

GuidelinesCabinet Requirement

Cabinet airflow requirements

When you mount the switch in a cabinet, ensure that ventilation through the cabinet is sufficient to prevent overheating.

Ensure that the cool air supply you provide through the cabinet adequately

•

dissipates the thermal output of the switch (or switches).

Ensure that the cabinet allows the chassis hot exhaust air to exit the cabinet

•

without recirculating into the switch. An open cabinet (without a top or doors) that employs hot air exhaust extraction from the top allows the best airflow through the chassis. If the cabinet contains a top or doors, perforations in these elements assist with removing the hot air exhaust.

The QFX5100 device fans exhaust hot air either through the vents on the

•

port panel or through the fans and power supplies. Install the switch in the cabinet in a way that maximizes the open space on the FRU side of the chassis. This maximizes the clearance for critical airflow.

Route and dress all cables to minimize the blockage of airflow to and from

•

the chassis.

Ensure that the spacing of rails and adjacent cabinets allows for the proper

•

clearance around the switch and cabinet.

Plan a Virtual Chassis Fabric Deployment

A Virtual Chassis Fabric (VCF) architecture supports up to 20 interconnected devices that are managed as a logical single device. Supported platforms vary depending on the QFX Series switch chosen for the spine. See Understanding Virtual Chassis Fabric Components and Virtual Chassis Fabric Hardware Overview for supported configurations. Although the architecture has a powerful auto-provisioning option, which allows you to plug and play the devices, careful planning of the deployment can avoid unexpected results.

For example, if you perform any configuration level commands on one of the devices (including assigning IP addresses or host names) you no longer can use auto-provisioning.

Use the following checklist to plan your deployment:
