Telecom and cable operators deploy the Cisco ASR 9000 with the A9K-40GE-E 40-Port GE Extended Line Card (requires SFPs) at the metro edge to aggregate hundreds of 1 GbE customer circuits onto a resilient backbone. Leveraging 40×1 GbE ports, SFP-based optics and built-in MPLS, providers achieve pay-as-you-grow scalability, simplified optical reach planning and carrier-grade uptime. Outcome: Up to 80% reduction in port-churn CAPEX, sub-microsecond MPLS convergence and streamlined operations across multi-service networks.
Mobile network operators integrate the A9K-40GE-E line card into ASR 9000 platforms to terminate and aggregate 5G RAN streams over 40×1 GbE interfaces using SFPs. With native IEEE 1588v2 and SyncE support, the solution delivers low-latency transport, precise timing and SLA assurance for voice, data and IoT services. Outcome: Guaranteed sub-50 µs latency, zero-packet loss during failover and tangible OPEX savings through consolidated backhaul infrastructure.
Large enterprises leverage the Cisco ASR 9000 chassis with the A9K-40GE-E card to connect campus buildings, branch offices and data closets via 40×1 GbE SFP links. Integrated MPLS/VPN and advanced QoS enable secure multi-tenant segmentation, end-to-end traffic engineering and real-time voice/video prioritization. Outcome: Dramatic footprint reduction, simplified SFP inventory management and the ability to scale port density by 60% without forklift upgrades.

The Cisco A9K-40GE-E is a 40-port Gigabit Ethernet Extended line card for the ASR 9000 Series, providing high-density 1GE connectivity and requiring SFP modules for optical or copper links.
The A9K-40GE-E supports 40 independent Gigabit Ethernet ports per card, enabling up to 40 simultaneous 1Gbps links.
The card is compatible with Cisco SFP-1000BASE-SX, SFP-1000BASE-LX, SFP-1000BASE-ZX and SFP-GE-T modules for multimode, single-mode or copper connections.
The A9K-40GE-E requires Cisco IOS XR Release 5.3.3 or later to enable full feature support, including advanced QoS, multicast and MPLS.
Each A9K-40GE-E delivers up to 40 Gbps aggregate throughput with 80 Gbps slot-switching capacity when paired in a dual-slot configuration.
The A9K-40GE-E is supported in Cisco ASR 9001, 9006, 9010 and 9922 chassis with an eight-slot or greater line card shelf.
The A9K-40GE-E consumes up to 90W per card under full load and requires redundant AC or DC power supplies in the ASR 9000 chassis.
The card operates at 0°C to 40°C (32°F to 104°F) with relative humidity of 5% to 85% non-condensing and meets NEBS Level 3 compliance.
To install, power down the chassis, slot the card into an available line card bay, secure the captive screws and then power up the system to begin software recognition.
Yes, the A9K-40GE-E can coexist with other ASR 9000 line cards in the same chassis, subject to power and cooling capacity guidelines.
After installation, use the IOS XR CLI to assign interfaces, apply VLANs, configure QoS policies and verify link status with the `show interfaces` command.
Cisco provides a limited lifetime warranty on the A9K-40GE-E, including return-to-factory hardware replacement and 90-day technical support.
Ideal use cases include large-scale aggregation, data center leaf-spine interconnects and service provider edge deployments requiring high port density and carrier-grade features.
