Ciena NTK505DS WOPUAC9FAA DC Power Card ActivFlex 6500

The Ciena NTK505DS DC Power Card is a dedicated DC input module for the ActivFlex 6500 Packet-Optical Platform. It provides two independent 50 A DC power paths in a breakerless configuration to feed the ActivFlex 6500 chassis and its installed line cards and subsystems. The part is cataloged under the ActivFlex 6500 family as NTK505DS, with the HECI reference WOPUAC9FAA. As a DC power input card, it occupies the power distribution slot within supported 6500 shelves and is designed to support stable, continuous operation in high-capacity transport networks. This card is intended for use specifically with ActivFlex 6500 systems and is identified in reseller catalogs as the standard DC power input component for the 6500 series. In practice, it plays a critical role in enabling the platform's modular power architecture by providing dedicated DC power to the shelf's power distribution network, supporting reliable operation of the platform's modules in data-center or carrier environments.
