Questions & Answers
What is the Cisco ASR 9000 Line Card A9K-8T-E?
The Cisco ASR 9000 Line Card A9K-8T-E is an extended 8-port 10 Gigabit Ethernet module designed for ASR 9000 Series Routers. It delivers high-density packet forwarding and scalability, requiring external XFP transceivers for optical connectivity.
How many 10GE ports does the A9K-8T-E support?
The A9K-8T-E provides eight independent 10 Gigabit Ethernet ports, enabling high-density aggregation and uplink options for service providers and large enterprise networks.
Which XFP transceivers are compatible with A9K-8T-E?
The A9K-8T-E supports Cisco-branded XFP modules compliant with IEEE 802.3ae (10GBase-SR/LR) and vendor-neutral XFPs certified for 10 Gigabit Ethernet optical interfaces.
What forwarding capacity does the A9K-8T-E deliver?
This line card offers up to 160 Gbps of forwarding bandwidth (full-duplex) and supports up to 1.2 billion packets per second (bpps), ensuring low latency and high throughput for demanding applications.
Is the A9K-8T-E hot-swappable?
Yes. The A9K-8T-E is fully hot-swappable, allowing insertion and removal without powering down the ASR 9000 chassis, which minimizes service disruption and supports seamless maintenance.
What are the power requirements for A9K-8T-E?
The A9K-8T-E consumes approximately 60 Watts. Exact power draw depends on XFP transceivers and traffic load. Ensure adequate power supply capacity in the ASR 9000 chassis.
Which ASR 9000 chassis support the A9K-8T-E line card?
The A9K-8T-E is compatible with Cisco ASR 9001, 9006, 9010, 9922, and 9948 routers. Verify chassis firmware meets the minimum recommended release for optimal interoperability.
How do I install the Cisco A9K-8T-E line card?
Power off the ASR 9000 chassis (if required), slide the A9K-8T-E into an available slot until it latches, reconnect XFPs, then power on. Confirm installation via CLI with the "show platform" command.
Does Cisco provide warranty coverage for the A9K-8T-E?
Yes. The A9K-8T-E includes a limited lifetime warranty that covers defects in materials and workmanship. Cisco SMARTnet™ support contracts are available for extended hardware replacement and technical assistance.
Are software licenses required to enable all ports?
All eight ports are enabled by default, but advanced features (e.g., MPLS, QoS) require valid Cisco IOS XR software licenses. Verify feature entitlements in your service contract.
Can I mix A9K-8T-E with other line cards in the same chassis?
