IBM 73Y9549 zEnterprise 114/196 DCA-CY DC/DC Converter module.

The IBM 73Y9549 is a DCA-CY DC/DC converter module designed for use within IBM zEnterprise 114 and zEnterprise 196 mainframe systems. This power conversion component transforms DC voltage levels to supply regulated power to specific subsystems within the mainframe infrastructure.

DC/DC converters are critical components in enterprise mainframe environments, ensuring stable and efficient power distribution across the complex internal architecture of zEnterprise systems. The DCA-CY designation indicates a specific power rail or subsystem configuration within the mainframe’s power management hierarchy.

The IBM zEnterprise 114 and zEnterprise 196 are legacy mainframe platforms, with the 196 announced in 2010 and the 114 in 2011. Both systems have been discontinued by IBM, though many remain in production environments. This makes spare power components such as the 73Y9549 valuable for maintaining operational continuity of existing installations.
