IBM 45D8681 server / storage / networking hardware Server Hardware / Parts

The IBM 45D8681 is a DCA-family power/converter module for the IBM zEnterprise 114 mainframe, machine type 2818, part of the same Distributed Converter Assembly line as the DCA-ZGM and DCA-SN modules documented for this frame elsewhere. It converts the frame’s bulk DC power feed into the regulated voltages individual zEnterprise 114 components require, fitted as one of several redundant units so a single module failure does not interrupt power distribution. zEnterprise 114 frames of this generation remain in active service in established mainframe estates, and a genuine spare DCA module is a routine requirement for restoring power redundancy after a fault. Specifiers should confirm the exact power zone and DCA variant before ordering, since modules are matched to specific frame positions. Tech-Star (UK-based, shipped worldwide) stocks IBM zEnterprise components to support ongoing mainframe maintenance projects.
