IBM 46K3783 server / storage / networking hardware Server Hardware / Parts

The IBM 46K3783 is an EPO switch assembly, listed as EPO_SWTCH. The emergency power off circuit lets a frame be shut down immediately from the machine room, either at the frame itself or through the room’s own EPO system, and IBM treats it as a serviceable assembly in its own right. Which switch assembly fits depends on the machine type and the frame generation, so tell us the system it is destined for and we will check what we hold.

Machines of this class are maintained at field replaceable unit level. A frame holds a central electronics complex of processor books and memory, I/O drawers carrying the channel and network adapters, a bulk power subsystem and its own cooling. Engineers replace the failing unit rather than the machine, which is why individual assemblies from the z9, z10, z196 and zEC12 generations and their equivalent Power frames still trade actively years after those systems shipped.

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.
