ACX7348 System Overview

The Juniper Networks® ACX7348 Cloud Metro Router is a multiservice platform from the ACX7300 series that addresses the growing demands of metro applications. With a compact 3-U semi-fixed form factor, this industrial-rated router offers an aggregation solution that gives cloud providers and service providers the performance and scalability needed as networks grow.

The ACX7348 router provides 1-Gigabit Ethernet (GbE) through 400GbE port flexibility and a throughput of 2.4 Tbps. It has a fixed Flexible PIC Concentrator (FPC), dual Routing Engines, three bays for pluggable interface modules, redundant power supply modules (AC or DC), and four fan trays (two fans per tray). The ACX7348 router supports the following pluggable FPCs:

• ACX7K3-FPC-2CD4C—Two 400GbE and four 100GbE ports

• ACX7K3-FPC-16Y—Sixteen 50GbE ports

The ACX7348 router runs the Junos OS Evolved cloud-optimized operating system. It provides several capabilities that include support for the latest protocol and traffic engineering technologies, enhanced security, and precision timing for mobile backhaul applications. You can use these capabilities and features to create converged, virtualized, and automated architectures to address the rapid growth of 5G, IoT, and the cloud.

You can configure and monitor ACX7348 routers using Junos OS Evolved CLI. You can also onboard, manage, and monitor these routers using Juniper Paragon Automation.

• Compact and hardened cloud-era platform—Has a temperature-hardened and compact 3-U form factor that enables you to address a broad range of industrial applications.

• Always-on infrastructure—Provides full hardware redundancy for the Routing Engines and power supply modules (PSMs) to enable you to meet stringent service-level agreements (SLAs).

• Ease of deployment—Features a toolless setup and telescopic rails for a user-friendly installation, operation, and maintenance of the chassis.

• Next-generation capabilities—Supports next-generation protocols including segment routing, segment routing for IPv6 (SRv6), MPLS, and Ethernet VPN--Virtual Extensible LAN (EVPN-VXLAN).

• Media Access Control Security (MACsec) capabilities—Provides data plane security with inline MACsec support. MACsec is supported on all ports except the eight QSFP28 ports on the fixed FPC.

• High-power ZR/ZR+ transceiver support—Leverages an efficient thermal design to enable you to use unrestricted high-power ZR/ZR+ transceivers across all supporting ports.

Field-replaceable units (FRUs) are router components you can replace at the customer site. Replacing most FRUs requires minimal router downtime. The ACX7348 router uses the following types of FRUs:

• Hot-insertable and hot-removable—You can remove and replace these components without powering off the router or disrupting the routing function.

• Hot-pluggable—You can remove and replace these components without powering off the router, but the routing function is interrupted until you replace the component.

The following hardware components provide redundancy on ACX7348 routers:

• Routing Engines—A redundant system on an ACX7348 consists of two Routing Engines that are available as field-replaceable units (FRUs). One Routing Engine functions as the primary and the other functions as the backup.

• Power supply modules (PSMs)—You can install up to two PSMs on ACX7348 routers to provide full power, 1+1 redundancy to the device. Each PSM provides power to all components in the router. If one PSM fails, or if you remove one PSM, the second PSM balances the electrical load without interruption.

The ACX7348 router runs Junos OS Evolved, which provides Layer 2 and Layer 3 switching, routing, and security services. Junos OS Evolved runs natively on Linux and has direct access to all Linux utilities and operations. It has a modular design that supports upgrades 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 it requires minimal effort to make it work on any platform. Junos OS Evolved has a modernized infrastructure, which ensures high availability, portability, faster innovation, and simplified upgrades.
