Cisco ASR 9000 1-Port 40-Gigabit Ethernet Modular Port Adapter

The Cisco ASR 9000 Series modular port adapters are engineered to deliver scalable, carrier-grade performance for the most demanding networks. This 1-port 40-Gigabit Ethernet modular port adapter is designed to slot into the Cisco ASR 9000 Series Aggregation Services Routers, providing a single, high-speed uplink that can be paired with QSFP optics to fit your distance and media needs. Built for reliability, low latency, and predictable performance, this adapter enables service providers and large enterprises to extend their core and edge networks with a compact, flexible, and hot-swappable solution. By integrating this module into the ASR 9000 platform, you gain the ability to scale bandwidth without replacing chassis or rearchitecting your network, all while maintaining Cisco’s renowned management, security, and operational simplicity.

• High-density 40-Gigabit uplink: A single 40G Ethernet port designed to maximize throughput on backbone links, data center interconnects, and high-performance uplinks between aggregation and core layers.
• Modular flexibility within the ASR 9000 ecosystem: Part of Cisco’s modular line cards, allowing you to tailor interface densities and port configurations in a single slot to match current and future traffic growth.
• QSFP optics required (sold separately): This adapter relies on compatible QSFP optics to establish the 40G link. Choose the appropriate transceiver based on distance, fiber type (single-mode or multi-mode), and your network topology.
• Hot-swappable design for minimal downtime: Designed to be inserted or removed without powering down the system in supported ASR 9000 chassis, enabling proactive maintenance and rapid upgrades with limited service impact.
• Carrier-grade performance and manageability: Engineered to deliver consistent, line-rate forwarding and robust reliability within large-scale networks, with Cisco IOS XR software support for advanced routing, QoS, and policy-based automation.

Technical Details of Cisco ASR 9000 1-Port 40-Gigabit Ethernet Modular Port Adapter

• Interface: 1 x 40-Gigabit Ethernet port (QSFP) slot-capable; requires compatible QSFP optics to enable the 40G link.
• Port type: 40G Ethernet; supports 40GBASE standards when paired with the appropriate transceiver and fiber.
• Compatibility: Designed for use with the Cisco ASR 9000 Series Aggregation Services Routers and compatible modular slots; must be installed in a supported chassis configuration.
• Form factor: Modular Port Adapter for Cisco ASR 9000 series line cards; designed for hot-swapping within the chassis according to Cisco maintenance procedures.
• Power and thermal characteristics: Depend on the chassis, slot, and transceiver choice; follow Cisco guidance for power budgeting, cooling, and airflow in the deployment environment.

how to install Cisco ASR 9000 1-Port 40-Gigabit Ethernet Modular Port Adapter

• Prepare the system: Verify the chassis power state, review the service window, and perform ESD precautions before handling any modular components.
• Identify the correct slot: Locate the appropriate modular slot on the Cisco ASR 9000 series router that supports the new port adapter and compatible line card configuration.
• Power-down as required: If your model supports hot-swapping, you may proceed without powering down the entire device; otherwise power down the system following Cisco’s recommended procedures.
• Install the adapter: Remove any protective covers, align the module with the chassis midplane, and slide it firmly into the slot until it is seated and latched.
• Attach QSFP optics: Insert the compatible QSFP transceiver into the adapter’s QSFP port and connect the optical fiber or copper cabling according to your network design and link length requirements.
• Secure and verify: Ensure the module is locked in place, cables are secured, and the system recognizes the new hardware. Power on if required and use the command-line interface to verify link status and transceiver detection (for example, show controllers and show interfaces commands).
• Initial health check: Confirm that environmental conditions meet minimum cooling and temperature guidelines and that there are no fault indications in the chassis management module or supervisor engine.
• Baseline configuration: Configure the 40G interface for the desired routing or switching role, applying any QoS, ACLs, or security policies as part of your standard network template.

Frequently asked questions

• What exactly is the Cisco ASR 9000 1-Port 40-Gigabit Ethernet Modular Port Adapter? It is a modular port adapter designed for Cisco ASR 9000 Series routers that provides a single 40-Gigabit Ethernet uplink. The module is intended to be used with QSFP optics to establish a 40G link and is part of Cisco’s scalable, modular architecture for high-capacity networks.
• Do I receive QSFP optics with this module? No. The QSFP optics and transceivers are sold separately. You must select the appropriate QSFP optics to match your distance, fiber type, and interface requirements.
• Can I install this in any ASR 9000 model? This module is compatible with supported modular slots within the Cisco ASR 9000 Series routers. Always verify model and slot compatibility with Cisco’s hardware matrix and your IOS XR version before installation.
• What deployment scenarios benefit from a 40G uplink? Ideal for backbone links, data center interconnects, high-speed interconnections between aggregation and core routers, and service-provider edge deployments requiring scalable, reliable bandwidth with predictable latency and throughput.
• What maintenance considerations should I keep in mind? Because the module is hot-swappable on compatible chassis, plan maintenance windows to minimize impact, ensure proper cooling, and verify optics are correctly seated. Regularly monitor interface status and link health using Cisco management tools.
