Ciena 164-0305-901 CN2000 Main CPU Card

Ciena 164-0305-901 CN2000 Main CPU Card is the central processing module for the CN2000 transport platform. Identified by the part number 164-0305-901, this card provides the primary control processor responsible for running the CN2000 software stack and coordinating operations across the chassis. As the main CPU, it interfaces with the system backplane and other CN2000 cards to manage software boot, fault monitoring, and high-level control tasks that enable service delivery on the platform. The CN2000 Main CPU Card plays a key role in system orchestration, enabling carrier-grade features for multi-service transport, including management of line cards, timing, and network topology decisions within the CN2000 family. By serving as the brains of the CN2000 shelf, this card concentrates core processing resources in a compact module designed for reliable operation in demanding telecom environments. The exact performance characteristics and supported interfaces depend on the CN2000 configuration and software release, but the 164-0305-901 designation identifies this specific cpu card variant within Ciena's CN2000 ecosystem.
