42D3346 IBM 600W Storage Power Supply and Fan Unit

The 42D3346 is a hot-pluggable internal combination AC power supply and cooling fan assembly (PSU) engineered for high-availability IBM System Storage disk arrays. Delivering up to 600 Watts of continuous power output, this legacy module regulates incoming electrical lines to sustain consistent voltage channels across arrays of high-performance hard drives and dual controller canisters. Featuring integrated dual-cooling fans within its structural chassis, the unit simultaneously pulls ambient heat away from internal drive backplanes. It slides directly into the rear storage bays, supporting hot-swap replacements without interrupting live SAN data pathways when paired in a redundant configuration.
