MX10016 System Overview

Benefits of the MX10016 Router

• System capacity— MX10016 scales to 38.4 Tbps (76.8 Tbps half- duplex) in a single chassis, with support for up to 1536 10-Gigabit Ethernet, 384 40-Gigabit Ethernet, and 384 100-Gigabit Ethernet interfaces.

• Full-scale IP and MPLS routing—The MX10016 delivers a distributed peering scale of 8.6 million entries in the forwarding information bases (FIBs, also known as forwarding tables) and 80 million entries in the routing information bases (RIBs also known as routing tables).

• Source Packet Routing in Networking (SPRING)—SPRING on the MX10016 provides additional flexibility per packet source. SPRING provides features such as network path and node protection to support MPLS fast reroute (FRR) mechanisms, enhanced network programmability, OAM functionality, simplified network signaling, load balancing, and traffic engineering functions.

• Always-on infrastructure base—The MX10016 is engineered with full hardware redundancy for cooling, switch fabric, and host subsystems—Routing and Control Boards (RCBs)—allowing service providers to meet stringent service-level agreements across the core.

• Nondisruptive software upgrades—The Junos operating system on MX10016 supports high availability (HA) features such as graceful Routing Engine switchover (GRES), nonstop active routing (NSR), and unified in-service software upgrade (unified ISSU), providing software upgrades and changes without disrupting network traffic.

Chassis Description

The MX10016 is 21 U tall. Two MX10016 chassis can fit in a standard 42 U rack when there is adequate cooling and power. All key MX10016 components are field-replaceable units (FRUs).

Figure 1 illustrates the components visible from the front of the chassis.

Some chassis ship with an enhanced power bus to support the power needs of higher wattage line cards. Chassis with the enhanced power bus have a modified Status Panel (see MX10016 Status Panel LEDs).

Figure 2 illustrates the components that are visible from the rear of the chassis.

Figure 3 illustrates the components that are internal to the chassis.

See MX10016 Chassis Physical Specifications.

Routing and Control Board

The Routing and Control Board (RCB) (see Figure 4) contains a Routing Engine and is responsible for the system management and control in the MX10016. See MX10016 Routing and Control Board. 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 while the fully redundant configuration has two RCBs. The RCB also contains Precision Time Protocol ports and two Media Access Control Security (MACsec) capable ports (see MX10016 Components and Configurations).

Line Cards

The MX10016 has 16 horizontal line card slots and supports line rates for each line card. The line cards include a Packet Forwarding Engine and Ethernet interfaces enclosed in a single assembly. Line cards are FRUs that can be installed in the line card slots labeled 0 through 15 (top to bottom) on the front of the chassis. All line cards are hot-removable and hot-insertable. After the hot insertion, the line card comes online automatically.

The MX10016 router supports the following line cards:

• MX10K-LC2101—This line card provides a maximum bandwidth of 2.4Tbps and has six Packet Forwarding Engines, each providing a maximum bandwidth of up to 400 Gbps. The MX10K-LC2101 line card can support 24 100-Gigabit Ethernet ports with a 28-Gbps quad smallform-factor pluggable (QSFP28) transceiver, or 24 40-Gigabit Ethernet ports with a QSFP transceiver. The MX10K-LC2101 line cards also support 10-Gigabit Ethernet interfaces. For 10-Gigabit Ethernet, you must configure the port using the channelization command. Because there is no port-groups option for the 100-Gigabit Ethernet line card, you must use individual port channelization commands.

  Figure 5 shows the MX10K-LC2101 line card.

• MX10K-LC480—The MX10K-LC480 line card is a fixed configuration MPC with 48 ports. Each port supports a speed of 10 Gbps or 1 Gbps, providing the line card a maximum bandwidth of 480 Gbps. The MX10K-LC480 has two Packet Forwarding Engines, each providing a maximum bandwidth of up to 240 Gbps.

Switch Fabric Boards

Five Switch Fabric Boards (SFBs) provide the necessary switching functionality to an MX10016 router. A sixth SFB is available in the redundant configuration to provide n+1 redundancy. SFBs are installed between the line cards and the fan trays inside the chassis (see Figure 8). Each MX10016 SFB has sixteen connectors that match to a line card slot, eliminating the need for a backplane. When all the SFBs are installed, the MX10016 router has a net switching capacity of 2.4 terabytes per second (bidirectional). See MX10016 Switch Fabric Board.

Cooling System

The cooling system in the MX10016 consists of two hot-removable and hot-insertable FRU fan trays and two fan tray controllers.

Two fan tray models (JNP10016-FAN and JNP10016-FAN2) and their associated fan tray controllers (JNP10016-FAN-CTRL and JNP10016-FTC2) are available. The fan trays install vertically on the rear of the chassis and provide front to back chassis cooling. For model differences, see MX10016 Cooling System and Airflow.

Power Supplies

Power supplies for the MX10016 router are fully redundant, load-sharing, and hot-removable and hot-insertable FRUs. Each MX10016 router with a base configuration has five power supplies; redundant configurations hold a maximum of ten AC or DC power supplies. Each power supply has an internal fan for cooling. See Figure 11 through Figure 14.

CAUTION:

Do not mix AC and DC power supplies in the same chassis.

Table 1 provides an overview of the differences among the power supplies.

Software on MX10016

The MX10016 router runs Junos OS, which provides Layer 3 routing services. The same Junos OS code base that runs on the MX10016 router also runs on all Juniper Networks M Series, MX Series, and T Series routers and SRX Series Services Gateways.
