IBM 74Y9347 server / storage / networking hardware Server Hardware / Parts

The IBM 74Y9347 is a processor voltage regulator module (VRM), IBM feature code 30P, CCIN 2BF9, a genuine IBM component for 4-processor system configurations. It converts the system’s main supply voltage down to the lower, tightly-regulated voltage a processor module actually runs on, and is fitted close to the processor socket it serves so that voltage delivery stays within the processor’s tolerance under load. A VRM is a common failure point on Power-generation servers because it runs hot and switches continuously, and its failure symptoms (a processor that will not power on, or a system that reports a processor fault) can look like a CPU failure even though the processor card itself is fine. Genuine IBM VRMs of this kind are a routine requirement for restoring a faulted processor socket to service on an established 4-processor Power deployment. Specifiers should confirm their exact system model and processor configuration before ordering. Tech-Star (UK-based, shipped worldwide) supports ongoing server maintenance projects.
