Three
When the server is configured with three power supplies, the user can hot swap a failed supply without affecting system functionality.
The midplane provides power distribution of the internal power system with minimal active cir- cuitry. The power distribution circuitry reports quantity and location of the installed power supplies
through I2C* server management.
Two
The Profusion carrier provides headers for two processor mezzanine boards, each providing four slots for Pentium III Xeon processors. Each mezzanine board has six integrated VRM 8.3 compatible voltage converters. The converter input is +12 Vdc from the power supply. Each Pentium
IIIXeon processor core has its own converter. One converter provides power for a pair of Pen- tium III Xeon processor L2 caches.
The total power requirement for the OPRF100 board set exceeds the 240 VA energy hazard limit that defines an operator accessible area. As a result, only qualified technical individuals should access the processor, memory, and
