PTX10004 System Overview

PTX10004 Hardware Overview

The Juniper Networks PTX10004 Packet Transport Router addresses the business challenges of carriers and content providers to deliver more traffic at lower costs. For more information, read the following topics.

System Overview

The PTX10004 is the most compact, high-density, and power-efficient modular chassis in the PTX10000 line of modular packet-routing transport routers. At only 7 U in height, the PTX10004 is designed for today’s space-constrained facilities. Like the larger PTX10008 router, the PTX10004 supports Juniper’s 400GbE architecture with inline Media Access Control Security (MACsec) on all ports for point-to-point security on Ethernet links. Each PTX10K-LC1201-36CD line card has a throughput of up to 14.4 Tbps, giving the chassis an effective switching capacity of 57.6 Tbps. That throughput means a fully equipped PTX10004 can support 576 10GbE, 576 25GbE, 144 40GbE, 576 100GbE, or 144 400GbE interfaces in a single chassis. The PTX10004 supports the same feature set and runs the same Junos OS Evolved operating system as the PTX10008.

Benefits

The PTX10004 Packet Transport Router is the small-footprint complement to the larger PTX10008 modular chassis with these benefits:

  • Ease of deployment—The PTX10004 features a compact 7-U modular chassis for sites with limited space or power.

  • Modular, flexible design—The PTX10004 uses the custom silicon line-cards (14.4 Tbps and 9.6 Tbps throughput) and power supplies found in the larger PTX10008 modular chassis.

  • Proven fabric and chassis design—The PTX10004 has the same updated fabric and chassis design features found on the PTX10008 router.

Chassis Description

The PTX10004 router is 7-U tall. You can fix up to six PTX10004 routers in a standard 42-U rack with adequate cooling and power. All key PTX10004 router components are field-replaceable units (FRUs). Figure 1 illustrates the key components visible from the front of the chassis, Figure 2 illustrates the components that are visible from the rear of the chassis, and Figure 3 illustrates the components that are internal to the chassis.

Switch Fabric

Switch Interface Boards (SIBs) create the switch fabric for the PTX10004. Each SIB has a set of connectors to mate the line cards and the Routing and Control Board (RCB) to the switch fabric. See Figure 4 for an example of the JNP10004-SF3.

For the JNP10004 switch fabric, three SIBs provide the minimum switching functionality to a PTX10004 router; six SIBs provide full throughput. SIBs are installed between the line cards and the fan trays inside the chassis. Each PTX10004 SIB has four connectors that match to a line-card slot, eliminating the need for a backplane. See PTX10004 Switch Interface Board Description.

You can order the PTX10004 with different SIB configurations that allow you to grow your system as needed. See Table 1. For full 400 Gbps deployments, we recommend the PTX10004-PREM3 configuration. See PTX10004 Components and Configurations for a full description of these configuration options.

Routing and Control Board

The Routing and Control Board (RCB) contains a Routing Engine and is responsible for system management and system control in the PTX10004. See PTX10004 Routing and Control Board Components and Descriptions. RCBs are field-replaceable units (FRUs) that are installed in the front of the chassis in the slots labeled CB0 and CB1.

The supported models of RCB for JNP10008-SF3 fabric systems are:

  • JNP10K-RE1-E, 64 gigabytes of memory

  • JNP10K-RE1-E128, 128 gigabytes of memory

These RCBs runs Junos OS Evolved. See Figure 5.

Figure 5: JNP10K-RE1-E, and JNP10K-RE1-E128JNP10K-RE1-E, and JNP10K-RE1-E128

The base configuration has a single RCB. The fully redundant configurations have two RCBs. The RCB also contains Precision Time Protocol (PTP) ports and four Media Access Control Security (MACsec) capable ports. See PTX10004 Components and Configurations.

Line Cards

The PTX10004 has four horizontal line-card slots. The line cards combine a Packet Forwarding Engine and Ethernet interfaces enclosed in a single assembly. The PTX10004 line-card architecture is based on a number of identical, independent Packet Forwarding Engine slices. Line cards are FRUs that can be installed in the line-card slots labeled 0 through 3 (top to bottom) on the front of the chassis. All line cards are hot-removable and hot-insertable. After the hot insertion, you need to bring the card online (see Take a PTX10004 Line Card Online or Offline).

The PTX10004 supports:

  • PTX10K-LC1201-36CD—a 36-port multiple-speed line card that can be configured as 400GbE, 200GbE, 100GbE, 50GbE, 25GbE, or 10GbE Ethernet ports.

  • PTX10K-LC1202-36MR—A 36-port line card (thirty-two 100GbE ports and four 400GbE ports). The 400-Gigabit Ethernet ports can be configured as either 400-Gigabit uplinks or channelized to 4 independent 100-Gigabit downstream ports.

See Figure 6 for an example of a PTX10004 line card.

Cooling System

The cooling system in a PTX10004 consists of two fan trays (see Figure 7) and two fan tray controllers (see Figure 8).

The JNP10004-FAN2 fan tray contains an array of six fans and operates as a single hot-removable and hot-insertable field-replaceable unit (FRU). The fan trays install vertically on the rear of the chassis and provide front-to-back chassis cooling. See PTX10004 Cooling System and Airflow.

Figure 7: Fan Tray JNP10004-FAN2Fan Tray JNP10004-FAN2

There is a corresponding fan tray controller, JNP10004-FTC2, for each JNP10004-FAN2 fan tray. See Figure 8.

Figure 8: Fan Tray Controller JNP10004-FTC2Fan Tray Controller JNP10004-FTC2

Power Supplies

The PTX10004 router support AC, DC, high-voltage alternating current (HVAC), and high-voltage direct current (HVDC), by offering the following power supplies:

  • JNP10K-PWR-AC2

  • JNP10K-PWR-DC2

Power supplies for the PTX10004 are load-sharing hot-removable and hot-insertable FRUs. The router operates with three power supplies. Each power supply has an internal fan for cooling. You can install the power supplies in any slot. See Figure 9 and Figure 10.

CAUTION:

Do not mix power supply models in the same chassis in a running environment.

The PTX10004 supports four PTX10K-LC1201-36CD line cards in non-redundant mode. If you populate all four slots with this line card, a power alarm is raised, which is expected behavior.

Software

The Juniper Networks PTX10004 packet transport router runs on the Junos OS Evolved operating system, which provides Layer 3 routing services. Junos OS Evolved is the next-generation Junos OS. It has the same CLI, the same features, and, in some cases, even the same processes as in the previous versions of Junos OS. However, its infrastructure is entirely modernized.

Note:

If you want to purchase additional power supplies (AC, DC, HVAC, or HVDC), SIBs, or RCBs for your router configuration, you must order them separately.

PTX10004 Component Redundancy

The PTX10004 router is designed so that no single point of failure can cause the entire system to fail. The following major hardware components in the redundant configuration provide redundancy:

  • Routing and Control Board (RCB)—The RCB consolidates the Routing Engine function with the control plane function in a single unit. The PTX10004 router can have one or two RCBs. When two RCBs are installed, one functions as the primary and the other functions as the backup. If the primary RCB (or either of its components) fails, the backup can take over as the primary. See PTX10004 Routing and Control Board Description.

  • Switch Interface Boards (SIBs)—The PTX10004 has six SIB slots for the JNP10004-SF3 SIBs. The switch fabric requires a minimum of three SIBs (BASE3 configuration) to provide the minimum switching functionality to a PTX10004 router. You can install up to six SIBs (PREM3 configuration), which is required for 14.4 Tbps line card support. However, a fully-loaded PTX10004 chassis with PTX10K-LC1201-36CD line cards is not a redundant configuration. See the PTX10004 Switch Interface Board Description.

  • Power supplies—The system requires three power supplies for minimum operation (two RCBs, two fan trays, three SIBs, and no line cards). The three power supplies provide n+1 redundancy for systems running 4.8-Tbps line cards and can tolerate a failure of a single power supply without system interruption. If one power supply fails in a fully redundant system, the other power supplies can provide full power to the PTX10004 router indefinitely. However, configurations that run 14.4-Tbps line cards in all four line-card slots don’t have redundant power. You can populate and run the 14.4-Tbps line cards but a power alarm is raised, which is expected behavior.

    The PTX10004 router also supports power source redundancy. Four sets of lugs are provided for the JNP10K-PWR-DC2 cables, and two AC power cords are provided for each JNP10K-PWR-AC2 power supply.

  • Cooling system—The PTX10004 has two fan trays, which are controlled by the fan tray controller. Each fan tray has a corresponding fan tray controller. If one of the fans in a JNP10004-FAN2 fan tray fails, under most conditions the fan tray rebalances the remaining fans to continue. The fan tray continues to operate indefinitely and provide sufficient cooling even when a single rotor fails in a fan, provided the room temperature is within the operating range. See PTX10004 Cooling System and Airflow.
