Cisco A9K-MPA-1X40GE ASR 9000 1-Port 40GE QSFP+ Modular Port Adapter RefurbishedProduct DetailsCisco A9K-MPA-1X40GE – ASR 9000 1-Port 40-Gigabit Ethernet Modular Port Adapter

The Cisco A9K-MPA-1X40GE is a 1-port 40-Gigabit Ethernet Modular Port Adapter (MPA) engineered for Cisco ASR 9000 Series Aggregation Services Routers. Designed for service provider core, edge, and aggregation networks, this MPA delivers line-rate 40Gbps throughput, ultra-low latency, and the investment protection that the ASR 9000 modular architecture is known for. It installs into MPA-capable line cards such as the A9K-MOD80 and A9K-MOD160, providing full Layer 2 and Layer 3 forwarding at wire speed. Running Cisco IOS XR, it supports a comprehensive set of carrier-grade features ideal for Metro Ethernet, data center interconnect (DCI), backbone, and IP/MPLS edge deployments.

Key Features & Benefits

• - 1 x 40GbE QSFP+ Port: Single high-speed 40-Gigabit Ethernet port using industry-standard QSFP+ interface. Supports Cisco-qualified transceivers including 40GBASE-SR4 (short-reach) and 40GBASE-LR4 (long-reach), as well as 4x10G breakout configurations for added flexibility.
• - Compatible with A9K-MOD80 and A9K-MOD160 Line Cards: Installs directly into either bay (bay 0 or bay 1) of ASR 9000 Series 80G and 160G modular line cards, enabling flexible port density expansion within existing ASR 9000 chassis infrastructure.
• - Line-Rate 40Gbps Forwarding: Delivers wire-speed performance with no throughput degradation even under full traffic load — critical for service provider environments running real-time video, IPTV, cloud services, and high-volume business traffic.
• - Hot-Swappable Design: Supports online insertion and removal (OIR) without requiring chassis shutdown or service interruption, minimizing downtime during upgrades and maintenance windows in carrier-grade environments.
• - Cisco IOS XR — Full SP Feature Set: Runs on Cisco IOS XR Software, supporting IPv4/IPv6 routing, MPLS, L2VPN, L3VPN, BGP, IS-IS, OSPF, traffic engineering, Hierarchical QoS (H-QoS), NetFlow, and offerirectional Forwarding Detection (BFD).
• - Jumbo Frame Support: Supports jumbo frames up to 9216 bytes, essential for data center interconnect, storage traffic, and high-performance enterprise backbone applications.
• - Carrier-Grade Reliability: Built to Cisco ASR 9000 carrier-class standards with hardware redundancy support, comprehensive system monitoring, and compatibility with Cisco IOS XR nonstop forwarding (NSF) and graceful restart capabilities.
• - Investment Protection: Part of the Cisco ASR 9000 MPA portfolio designed for long-term compatibility across the ASR 9000 modular chassis family — allows capacity upgrades without replacing existing line cards or Specifications
