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;
}
}
}
}
xiv
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]
xv
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.

Benefits of QFX10000 Modular Chassis Switches
System throughput—The Juniper Networks®QFX10008 line of modular switches delivers up to 96 Tbps
of system throughput to meet the rapid and ongoing traffic growth in data center, campus, and routing
environments. Industry-leading scale and density on the QFX10008 modular switches redefine per-slot
economics, enabling you to do more with less while simplifying network design and reducing operating
expenditures.
Logical scale—The QFX10008 modular switches deliver the highest Layer 2 / Layer 3 scale with up to 1
million MAC addresses, 2 million host routes, and 2 million FIB. The system also supports deep buffers
with up to 100ms packet buffering per port. Virtual output Queue (VoQ) based architecture prevents
head-of-line blocking.
22
Network architectures—The QFX10008 line can be deployed in a number of different network designs,
including IP fabrics, EVPN-VXLAN overlays for Layer 2 and Layer 3 networks, along with support for
DC edge and DCI use cases, giving customers complete architectural flexibility. Additionally, the open
architecture ensures that customers can innovate on top of Juniper Networks Junos®operating system
to accelerate the pace of innovation.
Chassis Description
The QFX10008 is 13 U tall. Up to 3 QFX10008 chassis can fit in a standard 42 U rack with adequate

Routing and Control Board
The Routing and Control Board (RCB) contains a routing engine and Control Board that is responsible for
system management and system control in the QFX10008 switch. See Figure 4 on page 26. RCBs are field
replaceable and installed in the front of the chassis in the slots labeled CB0and CB1. The base configuration
has a single RCB; the fully-redundant configuration has two RCBs. The RCB also contains Precision Time
Protocol (PTP) ports and four Media Access Control Security (MACsec) capable ports. See “QFX10000
Routing and Control Board Description” on page 92.
Figure 4: QFX10000 Routing and Control Board (QFX10000-RE)
Line Cards
The QFX10008 features eight horizontal line card slots and supports line rate for each line card. The line
cards combine a Packet Forwarding Engine (PFE) and Ethernet interfaces enclosed in a single assembly.
The QFX10008 line-card architecture is based on number of identical, independent PFE slices each with
500 Gbps full-duplex throughput. Line cards are FRUs that can be installed in the line-card slots labeled
0 through 7 (top to bottom) on the front of the switch chassis. All line cards are hot-removable and
hot-insertable.
26
The QFX10008 supports the following line cards:
QFX10000-36Q–provides 36 ports of 40-gigabit QSFP+. Twelve ports are designed to be 100-Gigabit
•
capable using QSFP28. Each of the 40-Gigabit QSFP+ can be configured as either a native 40-Gigabit
port or four 10-Gigabit ports using a breakout cable. With breakout cables, the line card supports a
maximum of 144 logical 10-Gigabit Ethernet ports.
QFX10000-30C–provides 30 ports of either 100-gigabit or 40-gigabit QSFP28. The ports autodetect
•
the type of transceiver installed and set the configuration to the appropriate speed. Each of the 40-gigabit
ports can be configured as either a native 40-gigabit port or four 10-gigabit ports using a breakout cable.
With breakout cables, the line card supports a maximum of 96 logical 10-Gigabit Ethernet ports.
QFX10000-30C-M–provides 30 ports of either 100-gigabit or 40-gigabit QSFP28 that support MACsec
•
security features.
QFX10000-60S-6Q–provides 60 SFP+ ports that can be configured for either 1-gigabit or 10-gigabit
•
speeds. The card also provides six flexible configuration ports for 100-gigabit and 40-gigabit speeds. Of
the six flexible configuration ports, two ports have QSFP28 sockets that support either 100-gigabit or
40-gigabit speeds. The remaining four ports have QSFP+ sockets that can be configured as either a
native 40-gigabit port or four 10-gigabit ports using a breakout cable. With breakout cables, the line
card supports a maximum of 84 logical 10-Gigabit Ethernet ports.
QFX10K-12C-DWDM-provides 6 coherent dense wavelength-division multiplexing (DWDM) ports with
•
built-in optics. The card supports MACsec security features and provides a flexible rate modulation at
100 Gbps, 150 Gbps, and 200 Gbps speeds.
See Figure 5 on page 27 for an example of a QFX10008 line card.

Switch Fabric
Five Switch Interface Boards (SIBs) provide the necessary switching functionality to a base configuration
QFX10008. A sixth SIB is available in the redundant configuration to provide n+1 redundancy. SIBs are
installed between the line cards and the fan trays inside of the chassis (see Figure 6 on page 27). Each
QFX10008 SIB has eight connectors that match to a line-card slot, eliminating the need for a backplane.
When all six SIBs are installed, the QFX10008 has a net switching capacity of 42 Tbps. See QFX10008
Switch Interface Board.

Cooling System
The cooling system in a QFX10008 consists of two hot-removable and hot-insertable field-replaceable
fan trays (see Figure 7 on page 28) and two fan tray controllers (see Figure 8 on page 28). The fan trays
install vertically on the rear of the chassis and provides front-to-back chassis cooling. See “QFX10008
Cooling System” on page 47.

Power Supplies
The QFX10008 switches support AC, DC, high voltage alternating current (HVAC) and high voltage direct
current (HVDC) by offering the following power supplies:
QFX10000-PWR-AC
•
JNP10K-PWR-AC2
•
QFX10000-PWR-DC
•
JNP10K-PWR-DC2
•
All of the power supplies are fully redundant, load-sharing, and hot-removable and hot-insertable
field-replaceable units (FRUs). Each QFX10008 base configuration has three QFX10000-PWR-AC or
QFX10000-PWR-DC power supplies; redundant configurations hold the maximum of six
QFX10000-PWR-AC or QFX10000-PWR-DC power supplies. There are also high-voltage alternating
current (HVAC), DC and high-voltage direct current (HVDC) base and redundant configurations. See
“QFX10008 Configurations and Upgrade Options” on page 31. Each power supply has an internal fan for
cooling. You can install the power supplies in any slot. See Table 3 on page 29 and Figure 9 on page 30
through Figure 12 on page 31. See QFX10000 Status Panel. Table 3 on page 29 provides the specifications
for these different power supplies.

CAUTION: Do not mix power supply models in the same chassis in a running
environment. DC and HVDC power supplies can coexist in the same chassis when you
hot swap of DC for an HVDC model. The system provides 2n source redundancy and
n+1 power supply redundancy. If one power source fails, the power supply switches
to the alternate source.
