MX10016 System Overview
The MX10000 line of 5G Universal Routing Platforms—including the MX10008 and MX10016 give cloud and service providers the performance and scalability needed to outpace increased traffic demands. MX10016 router provides 10-Gigabit Ethernet, 40-Gigabit Ethernet, and 100-Gigabit Ethernet modular solutions that support up to 2.4 Tbps per slot. The MX10016 router provides redundancy and resiliency. All major hardware components including the power system, the cooling system, the control board and the switch fabrics are fully redundant.
MX10016 Hardware Overview
Juniper Networks MX10016 Universal Routing Platform enables cloud and data center operators to transition from 10-Gigabit Ethernet and 40-Gigabit Ethernet networks to 100-Gigabit Ethernet high-performance networks. The 21 rack unit (21 U) modular chassis can provide 38.4 Tbps of throughput. The MX10016 router has 16 slots for the line cards that can support a maximum of 1536 10-Gigabit Ethernet ports, 384 40-Gigabit Ethernet ports, or 384 100-Gigabit Ethernet ports.
The MX10016 universal router provides 2.4 Tbps per slot fabric capacity for the service providers and cloud operators. You can deploy the MX10016 router in an IP edge network using an MX10K-LC2101 line card (ordering model number is JNP10K-LC2101).
You can deploy MX10016 in the edge of the network for the following functions:
Layer 3 peering
Data center gateway
Layer 3 aggregation
The MX10016 router is available in both base and redundant configurations for both AC and DC operation. MX10016 features front-to-back airflow (also known as airflow out or AFO).
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.
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.

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
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 Card (MX10K-LC2101)
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. The
MX10016 line card architecture is based on a number of identical,
independent Packet Forwarding Engine slices, each with 400 Gbps full-duplex
throughput. Line cards are FRUs that can be installed in the line
card slots labeled
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 MX10K-LC2101 line card is available for the MX10016. 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.
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 6). 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.
Two fan tray models and their associated fan tray controllers are available. Both models of fan tray contain 11 fans. 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 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 9 through Figure 12.
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.

You can install up to sixteen line cards in the router.
Line cards and the cable management system are not part of the base or redundant configurations. You must order them separately.
If you want to purchase additional power supplies (AC or DC), SFBs, or RCBs for your router configuration, you must order them separately.
MX10016 Component Redundancy
The MX10016 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 MX10016 router can have one RCB in a base configuration or two RCBs in a redundant configuration. 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 RCB. See MX10016 Routing and Control Board .
Switch Fabric Boards (SFBs)—The MX10016 router has six SFB slots. Five SFBs are required for base operation and the sixth SFB provides n+1 redundancy. All six SFBs are active and can sustain full throughput rate. The fabric plane can tolerate one SFB failure without any loss of performance. See MX10016 Switch Fabric Board.
Power supplies—The MX10016 router requires three power supplies for minimum operation. Additional power supplies, provide n+1 redundancy for the system. AC, DC, HVAC, and HVDC systems tolerate a single power supply to fail without system interruption. If one power supply fails in a fully redundant system, the other power supplies can provide full power to the MX10016 router indefinitely.
The MX10016 router also supports source redundancy. Two sets of lugs are provided for the JNP10K-PWR-AC cables, 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 fan trays have redundant fans, which are controlled by the fan tray controller. If one of the fans fails, the host subsystem increases the speed of the remaining fans to provide sufficient cooling for the router indefinitely. See MX10016 Cooling System .
