ACX6160 System Overview

ACX6160 Description

The Juniper Networks ACX6160 Universal Metro Router is a standalone optical transponder that has 12 network ports, of which 8 are client ports, and 4 are line ports. It has removable DC power supplies and cooling fans. It supports the Open ROADM Multi-Source Agreements (MSA) (Version 2.2.1).

The ACX6160 is a transparent transponder that supports:

  • Eight 100-Gigabit Ethernet/OTU4 client interfaces that support QSFP28 LR4 optics.

    Note:

    Only four client interfaces are currently supported.

  • Four 100-Gbps coherent dense wavelength division multiplexing (DWDM) line interfaces that support CFP2-DCO optics. These interfaces utilize quadrature phase shift keying (QPSK) modulation with Open ROADM (reconfigurable optical add/drop multiplexer)-compliant high-gain forward error correction(HG-FEC).

Table 1 describes the model.

Description

ACX6160-T-DC

This model includes the chassis, five fan modules, and two DC power supplies.

Benefits of the ACX6160

  • The ACX6160 provides full Open ROADM compatible transponder support for metro packet optical transport applications in a 1 U platform. Open ROADM-compatible APIs provide fully compliant third-party controller support along with HG-FEC-compliant interfaces, enabling true interoperable transponder functionality.

  • The ACX6160 supports a zero touch deployment (ZTD) feature that significantly reduces the time required to install and provision new equipment, resulting in lower OpEx, lower TCO, and greater operational efficiency. ZTD also reduces the complexity of deploying MPLS in the access layer.

  • Disaggregated and open-line system—The ACX6160 optimizes open-line system performance when combined with disaggregated control design. This enables flexible updates with service continuity and the freedom to deploy best transponder solutions.

Front Panel

The front panel of the ACX6160 contains 12 network ports, comprising eight client ports and four line ports, LEDs, console and management ports, and system status LEDs. Figure 1 shows the ACX6160 front panel.

ACX6160 Component Redundancy

The following hardware components provide redundancy on an ACX6160:

  • Power supplies—The ACX6160 has two power supplies. Each power supply provides power to all components in the device. The two power supplies provide full power redundancy to the device. If one power supply fails or is removed, the second power supply balances the electrical load without interruption. To provide power redundancy to the system, you must install both power supplies. Connect power source feed A to one power supply and power source feed B to the second power supply.

    CAUTION:

    Do not connect feed A and feed B to the same power supply input terminal.

  • Cooling system—The ACX6160 has five fan modules. If a fan module fails and the remaining fan modules are unable to keep the ACX6160 within the acceptable temperature thresholds, chassis alarms occur and the ACX6160 can shut down.

    CAUTION:

    Replace a failed fan module with a new fan module within 4 minutes of removal to prevent chassis overheating.

ACX6160 Field-Replaceable Units

Field-replaceable units (FRUs) are components that you can replace at your site. The ACX6160 FRUs are hot-removable and hot-insertable. You can remove and replace them without powering off the ACX6160 or disrupting the routing function.

The ACX6160 allows for two 50 GB serial advanced technology attachment (SATA) solid state drives (SSD) as a secondary boot drive or for log storage. The SATA SSD is a hot-insertable and hot-removable field-replaceable unit (FRU). The SSD cover plate is located on the top of the chassis.

Table 3 lists the FRUs for the ACX6160 and actions to take before removing them.

Note:

If you have a Juniper Care service contract, register any addition, change, or upgrade of hardware components at https://www.juniper.net/customers/support/tools/updateinstallbase/ . 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.
