PTX10004 System Overview

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. Each PTX10K-LC1202-36MR line card has a throughput of up to 4.8 Tbps. 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.

See PTX10004 Chassis Physical Specifications and PTX10004 Field-Replaceable Units.

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.

Table 1: Switch Fabric Configuration Overview

Configuration	Number of SIBs	Forwarding Capacity
PTX10004-BASE3	3	28.8 Tbps
PTX10004–PREM2	4	38.4 Tbps
PTX10004-PREM3	6	57.6 Tbps

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 JNP10004-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.

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.

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

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-AC3

• 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, Figure 10, and Figure 11.

CAUTION:

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

Table 2 provides an overview of the differences between the power supplies.

Table 2: Power Supply Overview

Power Supply Model	Input Type	Wattage
JNP10K-PWR-AC3	AC	7800 W (20-A input) with three or four active feeds 6000 W (20-A input) with two active feeds 3000 W (20-A input) with single active feed 7800 W (15-A input) with four active feeds 7500 W (15-A input) with three active feeds 5000 W (15-A input) with two active feeds 2500 W (15-A input) with single active feed
JNP10K-PWR-AC2	AC, HVAC, or HVDC	5000 W, single feed; 5500 W, dual feed
JNP10K-PWR-DC2	DC only	2750 W, single feed; 5500 W, dual feed

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.
