IBM 46K3995 server / storage / networking hardware Server Hardware / Parts

The IBM 46K3995 is a DCA, the distributed converter assembly used to power an individual drawer or book inside an IBM frame, listed with us as DCA-T24. Rather than one large supply, these machines regulate power in bulk at the frame and then convert it locally, which keeps the current paths short and lets a failed converter be replaced without taking the system down. Which DCA fits depends on the machine type and the drawer it serves.

IBM builds its large frame systems, the System z mainframes and the high end Power servers that share their packaging, around a bulk power subsystem rather than around individual power supplies. Mains comes in at the bulk power enclosure, is regulated and controlled there, and is distributed through the frame to converter assemblies at each book and drawer. Blowers, motor drive assemblies and, on the liquid cooled models, refrigeration or water cooling units hold the processor complex in its thermal envelope. Every one of those is a field replaceable unit.

Send us the machine type, or a photograph of the label on the part you are replacing, and we will confirm the match before anything ships. Tech-Star (UK-based, shipped worldwide) supplies IBM hardware for maintenance and expansion projects. Please contact our sales team for availability, condition and pricing.
