PTX10008 Hardware Overview

The Juniper Networks PTX10008 Packet Transport Router helps network operators achieve their business goals while effectively handling current and future traffic demands. For more information, read the following topics:



System Overview

The Juniper Networks PTX10008 Packet Transport Router enables cloud and data center operators to smoothly transition from 10-Gigabit and 40-Gigabit Ethernet networks to 100-Gigabit and 400-Gigabit Ethernet high-performance networks. This flexible, 13 rack unit (13-U) modular chassis has eight line card slots that can support a maximum of 288 400-Gigabit Ethernet ports that can also be configured as 576 200-Gigabit Ethernet ports, 1152 100-Gigabit Ethernet ports, 288 50-Gigabit Ethernet ports, 288 40-Gigabit Ethernet ports, 288 25-Gigabit Ethernet ports, or 1152 10-Gigabit Ethernet ports.

The switch fabric consists of six Switch Interface Boards (SIBs). There are two models of SIBs that correspond to the two types of switch fabric that support two different types of line cards. The JNP10008-SF SIB supports five standard line cards and operates in standard Junos OS. The JNP10008-SF switch fabric has a 42 Tbps of forwarding capacity. The JNP10008-SF3 SIB supports the 14.4 Tbps line card and operates in Junos OS Evolved systems. In the JNP10008-SF3 switch fabric the forwarding plane can provide 115 Tbps of forwarding capacity.

The PTX10008 (IP core) router is available in both base and redundant configurations for both AC and DC operation. All systems feature front-to-back airflow.

Benefits of the PTX10008 Router

  • System capacity—The PTX10008 Packet Transport Router has a 13-U form factor and supports 115.2 Tbps per chassis or 345.6 Tbps per standard 19-in. telecommunications rack, with support for up to 240 100-Gigabit Ethernet ports, 288 40-Gigabit Ethernet ports, or 1152 10-Gigabit Ethernet ports in a single chassis.

  • Full-scale IP and MPLS routing—PTX10008 software scales to thousands of BGP peers, tens of millions of routes in the routing tables,and supports high forwarding table scale suitable for internet peering deployments.

  • Source Packet Routing in Networking (SPRING)—SPRING on PTX10008 supports the latest SPRING innovations such as path provisioning via BGP SR-TE, and PCED protocols. It also supports many more features such as Topology independent loop free alternates (TI-LFA) and Operation, Administration, and Maintenance (OAM).

  • Always-on infrastructure base—The PTX10008 is engineered with full hardware redundancy for cooling, power, switch fabric, and control plane.

  • Nondisruptive software upgrades—The Junos operating system (Junos OS) on the PTX10008 supports high availability (HA) features such as graceful Routing Engine switchover (GRES), and nonstop active routing (NSR), providing software upgrades and changes without disrupting network traffic.

Chassis Description

The PTX10008 router is 13 U tall. Up to three PTX10008 routers can fit in a standard 42-U rack with adequate cooling and power. All key PTX10008 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.

Some chassis ship with an enhanced power bus to future-proof the chassis beyond the current generation of line cards. If you are using any of the JNP10008-SF3 compatible line cards, the standard chassis is sufficient for your operation. You can determine which chassis you have by markings on the status panel (see PTX10008 Status Panel).

Switch Fabric

Switch Interface Boards (SIBs) create the switch fabric for the PTX10008. There are two SIB models: JNP10008-SF and JNP10008-SF3. Each SIB model has a set of unique connectors to mate the line cards and the RCB to the switch fabric. Some system components are also designed to operate with a specific switch fabric. See Table 1 for the components that each switch fabric supports. Also see Figure 4 for an example of the JNP10008-SF SIB and see Figure 5 for an example of JNP10008-SF3.

For the JNP10008-SF switch fabric, five SIBs provide the necessary switching functionality to a PTX10008 router (see Figure 4). Up to six SIBs can be installed to provide n+1 redundancy. For the JNP10008-SF3 switch fabric, all six SIBs are required for operation. In both switch fabric configurations, SIBs are installed between the line cards and the fan trays inside the chassis. Each PTX10008 SIB has eight connectors that match to a line-card slot, eliminating the need for a backplane. See PTX10008 Switch Interface Board Description.

Each switch fabric has designated components.

Routing and Control Board

The Routing and Control Board (RCB) (see Figure 6) contains a Routing Engine and is responsible for system management and system control in the PTX10008. See PTX10008 Routing and Control Board Components and Descriptions. 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. The RCB also contains Precision Time Protocol (PTP) ports and four Media Access Control Security (MACsec) capable ports. See PTX10008 Configurations and Upgrade Options.

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

  • JNP10K-RE0

  • JNP10K-RE1

  • JNP10K-RE1-LT

  • JNP10K-RE1-128G

For JNP10008-SF3 fabric systems, the supported RCB is JNP10K-RE1-E or JNP10K-RE1-E128. This RCB runs Junos OS Evolved and supports 14.4 Tbps line cards.



Line Cards

The PTX10008 has eight horizontal line card slots. The line cards combine a Packet Forwarding Engine and Ethernet interfaces enclosed in a single assembly. PTX10008 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 7 (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 Taking a Line Card Online or Offline).

There are two types of line cards for the PTX10008, those line cards that are compatible with the JNP10008-SF switch fabric and those that are compatible with the JNP10008-SF3 switch fabric. The line cards that operate with the JNP10008-SF switch fabric are:

  • 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.

  • QFX10000-60S-6Q, a 66-port multiple speed line card that provides 60 small form-factor pluggable plus (SFP+) ports that support 10-Gbps or 1-Gbps port speeds. The line card also has 2 dual-speed QSFP28 ports that support either 40-Gbps or 100-Gbps port speed, and 4 QSFP+ ports that support 40-Gbps speed.

The line card that operates with the JNP10008-SF3 switch fabric is:

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

See Figure 7 for an example of a PTX10008 line card.

Cooling System

The cooling system in a PTX10008 router consists of two fan trays (see Figure 8) and two fan tray controllers (see Figure 9).

Two fan tray models and their associated fan tray controllers are available. The JNP10008-FAN fan tray contains an array of 11 fans and operates in systems with the JNP10008-SF switch fabric. The JNP10008-FAN2 fan tray contains an array of 22 fans and operates in either the JNP10008-SF switch fabric or in the JNP10008-SF3 switch fabric. These fan arrays operate as a single hot-removable and hot-insertable field-replaceable unit. The fan trays install vertically on the rear of the chassis and provide front-to-back chassis cooling. For model differences, see PTX10008 Cooling System and Airflow.

Figure 8: Fan Tray JNP10008-FAN
Fan Tray JNP10008-FAN

The two fan tray controllers also have two models that correspond to the two fan tray models. JNP10008-FAN-CTRL is the fan controller for the JNP10008-FAN and the JNP10008-FTC2 is the fan tray controller for the JNP10008-FAN2.

Power Supplies

PTX10008 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 PTX10008 router are fully redundant, load-sharing, and hot-removable and hot-insertable FRUs. Each PTX10008 router operates with a minimum of three AC power supplies to a maximum of six AC, high-voltage alternating current (HVAC), DC, or high-voltage direct current (HVDC) power supplies. Each power supply has an internal fan for cooling. You can install the power supplies in any slot. See Figure 10 through Figure 13.

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.

Note

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

Upgrade Kits

If you would like to be using newer technologies, such as 14.4 Tbps line cards, you can upgrade your existing PTX10008 router, MX10008 router, or QFX10008 switch hardware configurations to become one of the newer PTX10008 hardware offerings. You can convert your existing chassis to a PTX10008 router using an upgrade kit. Upgrading requires JNP10008-FAN2 and 5500 W power supplies. Depending on whether you already have the newer fan trays and power supplies will determine your upgrade kit. You can use Table 4 to find the right upgrade kit.

PTX10008 Component Redundancy

The PTX10008 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 control plane function in a single unit. The PTX10008 router can have one or two RCBs. When two RCBs are installed, one functions as the master and the other functions as the backup. If the master RCB (or either of its components) fails, the backup can take over as the master. See PTX10008 Routing and Control Board Components and Descriptions.

  • Switch Interface Boards (SIBs)—The PTX10008 routers have six SIB slots for either the JNP10008-SF or the JNP10008-SF3. You can’t mix the two types of SIBs in the same running chassis. For the JNP10008-SF switch fabric, five SIBs provide the necessary switching functionality to a PTX10008 router. Up to six SIBs can be installed to provide n+1 redundancy. For the JNP10008-SF3 switch fabric, all six SIBs are required for operation. All six SIBs are active and can sustain full throughput rate. See the PTX10008 Switch Interface Board Description.

  • Power supplies—On systems with the JNP10008-SF fabric configuration, the system requires three JNP10K-PWR-AC power supplies for minimum operation (two RCBs, two fan trays, six SIBs, and no line cards). Additional power supplies provide n+1 redundancy for the system. DC, HVAC, and HVDC systems require six 5.5KW power supplies 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 PTX10008 router indefinitely. In JNP10008-SF3 fabric configurations, six JNP10K-PWR-AC2 or JNP10K-PWR-DC2 power supplies are required for operation.

    The PTX10008 router also supports power source redundancy. Two sets of lugs are provided for the JNP10K-PWR-DC cables, four sets of lugs are provided for the JNP10K-PWR-DC2 cables, and two AC power cords are provided for each JNP10K-PWR-AC and JNP10K-PWR-AC2 power supply.

  • Cooling system—The PTX10008 has two fan trays with redundant fans, which are controlled by the fan tray controller. There are two models of fans, JNP10008-FAN and JNP10008-FAN2; each fan model has a corresponding fan tray controller (JNP10008-FAN-CTRL and JNP10008-FAN-FTC2). If one of the fans in a JNP10008-FAN fan tray fails, the host subsystem increases the speed of the remaining fans to provide sufficient cooling for the router indefinitely. If one of the fans in a JNP10008-FAN2 fan tray fails, under most conditions the fan tray will rebalance the remaining fans to continue. See PTX10008 Cooling System and Airflow.
