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;
}
}
}
}
xiii
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]
xiv
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 the PTX10016 Router
System capacity—The PTX10016 packet transport router has a 21 RU form factor and supports 48 Tbps
•
per chassis or 3 Tbps per slot, with support for up to 480 100-Gigabit Ethernet interfaces, 576 40-Gigabit
Ethernet ports, or 2304 10-Gigabit Ethernet ports in a single chassis.
Full-scale IP and MPLS routing—PTX10016 delivers the distributed peering scale of 2.9 million forwarding
•
information bases (FIBs) and 30 million routing information bases (RIBs) (also known as forwarding tables,
and routing tables, respectively), 3000 OSPF adjacencies, and 4000 BGP sessions that are required to
match expanding traffic demands.
Source Packet Routing in Networking (SPRING)—SPRING on PTX10016 provides additional flexibility
•
per packet source. SPRING provides network path and node protection to support MPLS fast reroute

Chassis Description
The PTX10016 is 21 U tall. Two PTX10016 chassis can fit in a standard 42-U rack with adequate cooling
and power. All key PTX10016 components are field-replaceable units (FRUs). Figure 1 on page 23 illustrates
the components visible from the front of the chassis, Figure 2 on page 24 illustrates the components that
are visible from the rear of the chassis, and Figure 3 on page 25 illustrates the components that are internal
to the chassis.

Some chassis ship with an enhanced power bus to support future-proof the chassis beyond the current
generation of line cards. You can determine which chassis you have by markings on the status panel, (see
“PTX10016 Status Panel” on page 38).

Routing and Control Board
The Routing and Control Board (RCB) (see Figure 4 on page 26) contains a Routing Engine and is responsible
for the system management and system control in the PTX10016. See “PTX10016 Routing and Control
Board Description” on page 74. RCBs are FRUs that are installed in the front of the chassis in the slots
labeled CB0 and CB1. The base configuration has a single RCB. The fully redundant configuration has two
RCBs. RCB contains Precision Time Protocol (PTP) ports and four Media Access Control Security (MACsec)
capable ports. See “PTX10016 Components and Configurations” on page 32.

Line Cards
26
The PTX10016 features 16 horizontal line card slots and supports line rate for each line card. The line
cards combine a Packet Forwarding Engine and Ethernet interfaces enclosed in a single assembly. The line
card architecture for PTX10016 routers is based on a 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 15 (top to bottom) on the front of the router chassis. All line cards are hot-removable
and hot-insertable.
The PTX10016 supports the following line card models:
PTX10K-LC1101, a 30-port 100-Gigabit or 40-Gigabit Ethernet quad small form-factor 28 (QSFP28)
•
line card. By default, the interfaces are created with 100-Gbps port speed. Using the CLI, you can set
the speed to 40-Gbps that can be used as either a native 40-gigabit interface or four independent
10-gigabit interfaces using a breakout cable. With breakout cables, the line card supports a maximum
of 96 logical 10-Gigabit Ethernet interfaces.
PTX10K-LC1102, a 36-port 40-Gigabit Ethernet line card that supports quad small form-factor plus
•
(QSFP+) transceivers. Twelve out of the 36 ports on this line card also support the 100-Gigabit Ethernet
QSFP28 transceivers. You can configure each of the QSFP+ ports as either a native 40-Gigabit Ethernet
interface or channelize the port as four 10-Gigabit Ethernet interfaces by using a breakout cable. When
the 40 Gigabit Ethernet port is channelized, the line card supports a maximum of 144 logical 10-Gigabit
Ethernet ports.
PTX10K-LC1104, a 6-port coherent dense wavelength-division multiplexing (DWDM) line card with
•
Media Access Control Security (MACsec). The line card features built-in optics that support flexible rate
modulation at 100-Gbps, 150-Gbps, and 200-Gbps speeds.
PTX10K-LC1105, a 30-port flexible configuration line card that supports QSFP+, QSFP28, QSFP28-DD,
•
QSFP56, and QSFP-DD transceivers. You can configure either as 100-Gigabit Ethernet interfaces or
as40-Gigabit Ethernet interfaces. The PTX10K-LC1105 line card supports MACsec security features.
See Figure 5 on page 27 for an example of a PTX10016 line card.

Switch Interface Boards
Five Switch Interface Boards (SIBs) provide the necessary switch fabric to a base configuration PTX10016
(see Figure 6 on page 28). 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 the chassis. Each PTX10016 SIB has 16
connectors that match to a line card slot, eliminating the need for a backplane. When all six SIBs are
installed, the PTX10016 has a net switching capacity of 96 Tbps. See “PTX10016 Switch Interface Board
Description” on page 82.

Cooling System
The cooling system in a PTX10016 consists of two hot-removable and hot-insertable FRU fan trays (see
Figure 7 on page 29) and two fan tray controllers (see Figure 8 on page 29). Each fan tray contains 21
fans. The fan trays install vertically on the rear of the chassis and provide front-to-back chassis cooling.
See “PTX10016 Cooling System and Airflow” on page 43.

Power Supplies
PTX10016 routers support AC, DC, high-voltage alternating current (HVAC) and high-voltage direct current
(HVDC) by offering the following power supplies:
JNP10K-PWR-AC
•
JNP10K-PWR-AC2
•
JNP10K–PWR-DC
•
JNP10K-PWR-DC2
•
Power supplies for the PTX10016 router are fully redundant, load-sharing, and hot-removable and
hot-insertable FRUs Each PTX10016 base configuration has five power supplies; redundant configurations
hold the maximum of ten AC, HVAC, DC, or HVDC power supplies. Each power supply has an internal fan
for cooling. You can install the power supplies in any slot. See Table 4 on page 30 and Figure 9 on page 30
through Figure 12 on page 31.
Table 4 on page 30 provides an overview of the differences among the 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.
