ACX7100-32C System Overview
ACX7100-32C Router Description
The Juniper Networks ACX7100-32C Cloud Metro Routers are high-performance routers with deep buffer capabilities and are designed to address the 100-Gigabit Ethernet to 400-Gigabit Ethernet service migration. With high port density and MACsec-ready ports, ACX7100-32C routers are ideal for secure and high-end service aggregation, large enterprise, and top-of-rack, spine-leaf data center applications.
The ACX7100-32C provides several capabilities that include a comprehensive set of features, advanced programmability, and seamless integration with emerging distributed edge compute architectures and spine-and-leaf data center applications.
You can configure and monitor ACX7100-32C routers using Junos OS Evolved CLI. You can also onboard, monitor, and manage these routers using Juniper Paragon Automation.
ACX7100-32C System Overview
The ACX7100-32C router is a 1-U, fixed-configuration router that has a high-throughput Packet Forwarding Engine, which provides a throughput of 4.8 Tbps. The Routing Engine and control plane are driven by the 2.9-Ghz six-core Intel CPU with 64-GB of memory and two 100-GB enterprise-grade solid-state drives (SSDs) for storage.
We ship the ACX7100-32C routers with redundant power supply modules (PSMs). You can order the routers with front-to-back airflow (airflow out or AO) and with AC or DC PSMs.

Benefits of ACX7100-32C Routers
Multiservice Solution—The ACX7100-32C is a highly versatile router that provides several capabilities, use-case specific features, and MACsec support on all ports. As an integral part of the cloud metro solution, these capabilities and features enable you to create converged, virtualized, and automated architectures to address the rapid growth of 5G, IoT, and cloud.
Advanced Timing features—Supports Class C timing and the major ITU-T timing profiles making it ideally suited for low latency service delivery.
MACsec capabilities—The ACX7100-32C router supports data plane security with inline MACsec on all ports.
Power-efficient footprint—Provides industry-leading power efficiency in a compact form factor to support ever-expanding bandwidth needs.
Zero-touch provisioning—Supports zero-touch provisioning (ZTP), which enables you to automate provisioning and deployment with minimal manual intervention. This helps save time and accelerate deployments.
ACX7100-32C Router Models
The ACX7100-32C routers are available with either AC or DC power supply modules (PSMs) and with airflow-out (AO) cooling. AO is also known as front-to-back or port-to-FRU cooling.

Field-Replaceable Units in ACX7100-32C Routers
Field-replaceable units (FRUs) are components that you can replace at your site. The following are the ACX7100-32C FRUs:
Power supply modules (PSMs)
Fan modules
Transceivers
Replace a failed PSM with a new PSM within three minutes of removal to maintain power redundancy. The router continues to operate with only one PSM running. Replace a failed fan module with a new fan module within one minute of removal to prevent chassis overheating.
If you have a Juniper J-Care service contract, register any addition, change, or upgrade of hardware components at https://www.juniper.net/customers/csc/management/updateinstallbase.jsp. Failure to do so can result in significant delays if you need replacement parts. This note does not apply if you replace existing components with the same type of component.
Before removing the optical transceivers, we recommend that you disable the interface using the set interfaces interface-name disable command.
Hardware Redundancy of ACX7100-32C Router Components and Functionality
The following hardware components provide redundancy on ACX7100-32C routers:
Power supply modules (PSMs)—The ACX7100-32C routers have two PSMs. Each PSM provides power to all components in the router. If two PSMs are installed, they provide full power redundancy to the device. If one PSM fails, or if you remove one PSM, the second PSM balances the electrical load without interruption.
To provide power redundancy to the system, both PSMs must be installed. Connect the first power source feed to one PSM, and connect the other power source feed to the second PSM.
CAUTION:Do not connect both the power source feeds to the same power supply input terminal.
Cooling system—The ACX7100-32C routers have six fan modules. If a fan rotor within a fan module fails, a chassis alarm is raised. The router continues to operate with one failed rotor as per GR-63 specifications. If more than one fan rotor fails, or if a fan module is removed, a chassis alarm is raised, and the system shuts down in 240 seconds. If more than one fan module is removed, a chassis alarm is raised, and the system shuts down immediately. Therefore, if any fan module fails, you must replace the fan module immediately.

ACX7100-32C System Software Overview
The ACX7100-32C runs Junos OS Evolved, which provides Layer 2 and Layer 3 switching, routing, and security services. Junos OS Evolved runs natively on Linux, giving it direct access to all Linux utilities and operations. It is designed to be modular, allowing for upgrades to be done on a component-by-component basis without a system reboot. Only those components that are changed are restarted. Junos OS Evolved is easily portable, and only minimal work is required to make it work on any platform. The Junos OS Evolved infrastructure is entirely modernized, giving you the high availability, portability, faster innovation, and simplified upgrades you need.
