PTX10002-36QDD System Overview

Juniper Networks® PTX10002-36QDD is a fixed-configuration router featuring 36 network ports that provide high-density and cost-efficient 800-Gigabit Ethernet (GbE) ports in a 2-U form factor. With a throughput of 28.8 Tbps, the PTX10002-36QDD is optimally designed for peering, core routing, and infrastructure edge routing roles in cloud provider, service provider, and content provider networks.

The PTX10002-36QDD port panel has 36 high-density ports and port LEDs.

The router operates in the normal power mode when 3000-W power supply units (PSUs) are installed in the router. The router operates in the power-optimized mode when 2200-W PSUs are installed in it. The ports support 800 Gbps speed in the normal power mode and provides a throughput of 28.8 Tbps. The ports support 400 Gbps speed in the power-optimized mode and provides a throughput of 14.4 Tbps.

The links on the ports come up at 400 Gbps speed by default, irrespective of the power mode. You can change the port speed to 800 Gbps by using the set interfaces <interface-name> speed <speed> command.

When the router is operating in the power-optimized mode, the ports support SFP+, QSFP+, QSFP28, QSFP56-DD, or high-power 400G-ZR transceivers. When the router is operating in the normal power mode, the ports support 800 Gbps transceivers additionally.

The management panel in the router is on the far right side of the front panel, above the port LEDs.

The rear panel houses the PSUs, fan modules, BITS port, the 10-MHz ports, pulse per second (PPS) ports, and a protective earthing terminal.

The router supports the following PSUs:

• 2200-W HVAC/HVDC

• 2200-W DC

• 3000-W HVAC/HVDC

• 3000-W DC

The cooling system in the router consists of three fan modules for the chassis and a single built-in fan in each PSU. The router supports front-to-back airflow.

• High availability hardware—The PTX10002-36QDD is engineered with hardware redundancy for cooling and power supply. With the router’s high availability, service providers can maintain an always-on infrastructure base that helps meet stringent service-level agreements (SLAs) across the core.

• Space and power efficiency—The router's ultra-compact 2-U form factor makes it space saving and critical in space-constrained and power-restricted internet exchange locations, remote central offices, and embedded peering points throughout the network. In 36x800 Gbps mode, with no optical transceivers installed, the router delivers a power efficiency of less than 0.055 watts/Gbps.

• Support for QSFP-DD800 transceivers—The PTX10002-36QDD supports universal multi-rate QSFP-DD800 optical transceivers, multiplying aggregate switch bandwidth while maintaining the port density. QSFP-DD800 transceivers support continuing growth in network bandwidth demand and data-center traffic.

• Support for channelization—You can channelize the ports on the PTX10002-36QDD and increase the number of interfaces.

• Junos OS^® Evolved—The PTX10002-36QDD operates on Junos OS Evolved, Juniper Networks next-generation Junos OS. Junos OS Evolved has the same CLI user interface, the same code base for applications and features, and the same management and automation tools as Junos OS. However, the Junos OS Evolved infrastructure is entirely modernized, delivering the high availability, portability, faster innovation, and simplified upgrades you need.

• Interoperability—The PTX10002-36QDD provides seamless interoperability with existing Juniper routing deployments.

The PTX10002-36QDD runs Junos OS Evolved, which provides Layer 2 and Layer 3 switching, routing, and security services. Junos OS Evolved runs natively on Linux, giving the OS direct access to all the Linux utilities and operations. Junos OS Evolved has a modular design, which allows for upgrades to be performed on a component-by-component basis without a system reboot. Only the components that are changed are restarted. Junos OS Evolved is easily portable and works on any platform, with minimal requirements. Junos OS Evolved and Junos OS have the same CLI, the same code base for applications and features, and the same management and automation tools. However, the Junos OS Evolved infrastructure is entirely modernized, giving you the high availability, portability, faster innovation, and simplified upgrades you need.

For information about which features are supported on PTX Series devices, see Feature Explorer.

You can channelize the ports to operate in the following speeds:

• 2x400 Gbps

• 8x100 Gbps

• 4x100 Gbps

• 3x100 Gbps

• 2x100 Gbps

• 2x50 Gbps

• 4x25 Gbps

• 4x10 Gbps

Table 1 lists the physical specifications for the PTX10002-36QDD chassis.
