PTX10001 System Overview

 

PTX10001 Packet Transport Router Description

Juniper Networks PTX10001 Packet Transport Router is a fixed-configuration MacSec enabled LSR core router. It features a compact 1U form factor that is easily deployed in space-constrained Internet exchange locations, remote central offices, and embedded peering points throughout the network.

Benefits of the PTX10001 Router

  • Scalability—The PTX10001 scales to 3.6 Tbps in a single chassis, supporting up to 144 10-Gigabit Ethernet interfaces, 36 40-Gigabit Ethernet interfaces, and 36 100-Gigabit Ethernet interfaces, giving cloud and service providers the performance and scalability needed as networks grow.

  • Performance—The PTX10001’s exceptional packet processing capabilities help alleviate the challenge of scaling the network as traffic levels increase while optimizing IP/MPLS transit functionality around superior performance. PTX10001 is tailored for LSR core router with support for 128K LSPs.

  • High availability hardware—The PTX10001 is engineered with hardware redundancy for cooling, power supplies, and forwarding. With the PTX1001’s high availability, service providers can maintain an always-on infrastructure base and to meet stringent SLAs across the core.

  • Space efficiency—The PTX10001’s ultra-compact 1U form factor efficiency is a critical requirement for peering internet exchange points, peering collocations, central offices, and regional networks. The PTX10001 is the first 1RU LSR router with MacSec support built in.

System Overview

The PTX10001 is a fixed-configuration router that supports 10-Gbps, 40-Gbps, and 100-Gbps port speeds in a single 1U stackable platform.

  • 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 PTX10001 router’s internal 2 x 50-gigabyte (GB) M.2 SATA solid-state drives (SSDs). The Routing Engine is enhanced by a 1.6-GHz 4 core Intel CPU and 24 GB of SDRAM.

  • Forwarding operations are performed by the Packet Forwarding Engine, which uses Juniper Networks Express-based silicon. The custom ASICs enable the PTX10001 to provide up to 3.6 Tbps of throughput and 2 Bpps of forwarding capacity.

Port Panel

The port panel of the PTX10001 contains 20 network ports, port LEDs, one bay for an optional expansion module, console and management ports, and system status LEDs. Figure 1 shows the PTX10001 port panel.

You manage the PTX10001 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.

Management Panel

The management panel of the PTX10001 is located on the FRU side of the device. It contains management ports, the fan modules, and power supplies for the PTX10001. Figure 2 shows the PTX10001 management panel.

PTX10001 Component Redundancy

The following hardware components provide redundancy on a PTX10001:

  • Power supplies—The PTX10001 has two power supplies. Each power supply provides power to all components in the device. 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 PTX10001 has five fan modules. If a fan module fails and the remaining fan modules are unable to keep the PTX10001 within the desired temperature thresholds, chassis alarms occur and the PTX10001 can shut down.

PTX10001 Field-Replaceable Units

Field-replaceable units (FRUs) are components that you can replace at your site.

Caution

Replace a failed fan module with a new fan module within 30 seconds of removal to prevent chassis overheating.

Table 3 lists the FRUs for the PTX10001 and actions to take before removing them.

Note

If you have a Juniper Care service contract, register any addition, change, or upgrade of hardware components at https://www.juniper.net/customers/support/tools/updateinstallbase/ . Failure to do so can result in significant delays if you need replacement parts. This note does not apply if you replace existing components with the same type of component.
