The A9K-2T20GE-B is a modular line card for the Cisco ASR 9000 Series, offering 2×10 Gigabit Ethernet and 20×1 Gigabit Ethernet ports for high-density edge and core routing.
This line card delivers 2×10 Gigabit Ethernet ports and 20×1 Gigabit Ethernet ports, enabling mixed-speed connectivity in a single module.
No. The A9K-2T20GE-B requires separately purchased Cisco XFP transceivers for 10 GE and SFP/Gbit transceivers for 1 GE connectivity.
Compatible Cisco optics include XFP modules such as Cisco XFP-10G-SR and SFP modules like SFP-1G-SX, SFP-1G-LX, or equivalent Cisco-approved SFPs.
The A9K-2T20GE-B is fully supported in Cisco ASR 9010 and ASR 9904/9906/9912 chassis running Cisco IOS XR.
It delivers up to 40 Gbps of aggregate line-rate throughput (2×10 GE + 20×1 GE) with non-blocking performance per slot.
Yes. The line card supports IEEE-compliant hot-swap operations, allowing insertion or removal without system downtime.
It requires Cisco IOS XR Release 4.2.3 or later with the appropriate feature licenses for advanced routing protocols.
Typical power draw is approximately 85 W under full load; please verify chassis power-budget capacity before deployment.
The line card operates between 0 °C to 45 °C (32 °F to 113 °F) and 5 %–85 % non-condensing relative humidity.
No additional hardware license is needed; you simply enable advanced features via Cisco IOS XR software licensing.
Ideal for metro aggregation, edge routing, service provider peering, and mobile backhaul where mixed 10 GE and 1 GE ports are required.
