PTX1000 Packet Transport Router Description
The Juniper Networks PTX1000 Packet Transport Router is a fixed-configuration router
that supports 10-Gbps, 40-Gbps, and 100-Gbps port speeds in a compact 2U form factor,
enabling service providers to organically distribute peering points throughout the network.
The system architecture cleanly separates control operations from packet forwarding
operations. This design eliminates processing and traffic bottlenecks, permitting the
PTX1000 to achieve high performance.
•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 PTX1000 router’s internal 2 x 64-gigabyte
(GB) M.2 SATA solid-state drives (SSDs). The 64-GB SSDs have 50 GB of usable
space—the remaining space is reserved. The Routing Engine is enhanced by a 2.5-GHz
quad core Intel CPU and 32 GB of SDRAM.
17Copyright © 2018, Juniper Networks, Inc.

NOTE: The 2 x 64-GB SSDs installed in the PTX1000 support the request
vmhost snapshot command, which creates a recovery snapshot of the
currently running and active file system partitions, and request vmhost
snapshot recovery command, which recovers the primary disk from the
snapshot content stored in the backup disk. In addition, the 64-GB SSDs
support enhanced hardware resiliency through storage partitioning and
redundancy.
Earlier versions of the PTX1000 have 2 x 32-GB M.2 SATA SSDs. PTX1000
routers with 32-GB SSDs do not support the request vmhost snapshot and
request vmhost snapshot recovery commands, and do not support enhanced
hardware resiliency. To determine the size of the SSDs installed in your
device, issue the show vmhost hardware CLI command. The capacity of
Disk1 and Disk2 is displayed in the output as 32.0 GB if 32-GB SSDs are
installed, and the capacity is displayed as 50.0 GB if 64-GB SSDs are
installed. See the Installation and Upgrade Guide for more information.
•Forwarding operations are performed by the Packet Forwarding Engines, which include
ASICs designed by Juniper Networks. The custom ExpressPlus ASICs enable the
PTX1000 to provide up to 2.88 terabits per second (Tbps) of forwarding capacity. The
ExpressPlus 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.
TIP: For information about features supported on PTX Series routers, see
Feature Explorer.

Benefits of the PTX1000 Router
•Increased scalability—The PTX1000 scales to 3 Tbps in a single chassis, supporting
up to 288 10-Gigabit Ethernet interfaces, 72 40-Gigabit Ethernet interfaces, and
24 100-Gigabit Ethernet interfaces, giving service providers the performance and
scalability needed as networks grow. The purpose-built ASICs in the PTX1000 provide
enhanced packet processing for both full IP functionality and MPLS transport,
accommodating scale as traffic continues to increase and optimizing IP/MPLS transit
functionality.
•Space efficiency—Providing high capacity in a compact 2U form-factor, the PTX1000
meets installation needs for peering Internet exchange points, peering collocations,
central offices, and regional networks, especially in emerging markets.

PTX1000 Packet Transport Router Hardware Guide

•Always-on infrastructure base—The PTX1000 is engineered with full hardware
redundancy for cooling, power supplies, and forwarding, allowing service providers to
meet stringent service-level agreements across the core.
Port Panel and Management Panel
The port panel of the PTX1000 contains 72 network ports and port LEDs. The management
panel of the PTX1000 contains console and management ports, a reset button, system
status LEDs, clocking ports, and a USB port. Figure 1 on page 19 shows the PTX1000 port
panel and management panel.
Figure 1: PTX1000 Port Panel and Management Panel
2—1— Management panelPort panel
Each of the 72 network ports on the port panel supports quad small form-factor pluggable
plus (QSFP+) transceivers, and is configured as a channelized 4 x 10-Gigabit Ethernet
interface by default (for a maximum of 288 10-Gigabit Ethernet ports). You can configure
each of the 72 ports as a 40-Gigabit Ethernet interface. You can also configure 24 of the
72 network ports as 100-Gigabit Ethernet interfaces. Table 3 on page 19 describes the
maximum number of ports for each interface type supported by the PTX1000.
Table 3: Maximum Supported Ports at Each Interface Speed
Maximum Supported PortsInterface Type
28810-Gigabit Ethernet
7240-Gigabit Ethernet
24100-Gigabit Ethernet
NOTE: You can purchase a licensed model of the PTX1000 that allows you
to use 18 of the 72 network ports. You can use 18 ports in any combination,
for a maximum of 72 10-Gigabit Ethernet interfaces, 18 40-Gigabit Ethernet
interfaces, or 6 100-Gigabit Ethernet interfaces. You can purchase additional
licenses to enable the remaining network ports. Each license enables an
additional 18 of the 72 total network ports.

Chapter 1: Overview

You manage the PTX1000 by using the Junos OS CLI, which is accessible through the
console and out-of-band management ports on the management panel. In addition, the
management panel has system status LEDs that alert you to minor or major alarms or
other issues with the router, external clock synchronization ports, and a USB port to
support software installation and recovery.
For more information about the port and management panels, see “PTX1000 Port Panel”
on page 23 and “PTX1000 Management Panel” on page 30.
FRU Panel
The field-replaceable unit (FRU) panel of the PTX1000 contains the fan modules and
power supplies for the PTX1000. Figure 2 on page 20 shows the PTX1000 FRU panel.
Figure 2: PTX1000 FRU Panel
3—1— ESD pointPower supplies (4)
2—Fan modules (3)
The cooling system in a PTX1000 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 module has dual counter-rotating fans. These fan modules can be
hot-swapped—you do not need to power off the router or disrupt routing function to
replace a fan module.
In the PTX1000 cooling system, cool air enters through the vents in the port panel and
hot air exhausts through the FRU panel. This type of airflow is known as airflow out or
port-to-FRU airflow.
The PTX1000 has four 1600-W power supplies, either AC or DC depending on your
configuration. Each power supply provides 12-VDC output with a standby voltage of
12 VDC. The power supplies can be hot-swapped—you do not need to power off the
router or disrupt routing function to replace a power supply
For more information about the components on the FRU panel, see “PTX1000 Cooling
System Description” on page 34,“PTX1000 AC Power Supply Description” on page 36,
and “PTX1000 DC Power Supply Description” on page 38.
