The ASR5K-4OC3C-SM-K9 is an OLC2 4-port ATM STM-1c/OC-3c line card with integrated single-mode SFPs, designed for Cisco ASR 5000 Series gateways to deliver reliable multi-service connectivity.
This line card is fully compatible with Cisco ASR 5000 Series (ASR5K) service gateways, including ASR 5001, 5003, 5006, and 5010 chassis, ensuring seamless integration.
Each of the four ports supports ATM STM-1c and OC-3c rates up to 155 Mbps, delivering high-performance transport for voice, video, and data services.
The line card ships with Cisco single-mode SFP transceivers preinstalled, supporting up to 15 km reach over single-mode fiber for long-distance WAN connectivity.
Power down the ASR5K chassis, slide the line card into an available OLC2 slot, secure it with the captive screws, then power up the system and verify with the CLI ‘show card’ command.
No. The OLC2 line card requires a system reboot to initialize. Always perform a controlled shutdown and power-cycle the ASR5K chassis before replacement.
You need the Cisco IOS XE Data Plane and Control Plane licenses. For advanced ATM features, purchase the optional ATM feature license from Cisco.
Use Cisco IOS XE CLI: define the virtual path with ‘atm pvc’, assign VPI/VCI values, map to a POL or SDP interface, then activate with ‘no shutdown’ under the ATM subinterface.
The line card supports Cisco Embedded Event Manager (EEM), Cisco IOS XE performance monitoring, and the ‘show atm’ and ‘show optical-transceiver’ commands for real-time diagnostics.
Engineered for carrier-grade performance, the ASR5K-4OC3C-SM-K9 delivers five-nines (99.999%) availability with redundant supervisor engines and continuous in-service software upgrades.
Operating temperature: 0°C to 40°C; humidity: 5% to 85% non-condensing. Complies with NEBS Level 3 standards for telecom safety, EMC, and thermal performance.
Run ‘show interfaces atm’ to check line status, and ‘show transceiver detail’ to view optical RSSI, temperature, voltage, and laser bias diagnostics for each SFP port.
Typical Cisco ASR5K line card lead time is 2–4 weeks, subject to stock availability and regional distribution schedules. Contact your Cisco reseller for precise delivery estimates.
Cisco provides a 90-day limited warranty on Cisco-branded hardware. Extended warranties and Cisco Smart Net Total Care support are available for hardware replacement and technical assistance.
