300-1917 Sun Fire E25K 4700W Power Supply Unit
Sun Microsystems internal 4700-Watt high-capacity dual AC input hot-swappable server power supply module.
The 300-1917 is an internal system power supply unit engineered to deliver cost-effective energy transformation and enhanced system stability within multi-node server frameworks. Functioning as a high-efficiency electrical regulation module, this 4700W dual alternating current (AC) input adapter balances incoming utility metrics to maintain uniform 48V DC outputs across main logic routing boards and heavy enterprise-processor grids. Designed with hot-pluggable architecture, it slides securely into the rear chassis of massive enterprise mainframe server configurations to provide immediate electrical backup and N+1 current redundancy. Its fault-isolated layout manages internal bus communication cleanly, shielding core operational paths from power surges, current fluctuations, or single-point-of-failure thermal drops during continuous high-availability runtime operations.
