8.6Processor expansion

Each Pentium III Xeon™ processor is packaged in a single edge contact (SEC) cartridge. The processor unit includes:

the processor core with an integrated 16 KB primary (L1) cache

the secondary cache (L2)

the thermal plate

the cover

The processor units are located on two processor carrier boards, which in turn are connected to the main processor carrier board. A processor carrier board can accommodate up to four processor units.

The server can accommodate up to eight Intel Pentium III Xeon™processors with a clock frequency of 550 MHz and/or 700 MHz and higher.

The 550 MHz processors are mounted on „Ocotillo mezzanine“ carrier boards, the 700 MHz and higher on „Palmetto mezzanine“ carrier boards.

VCAUTION!

In order to prevent a damage of the processors, pay attention that the processors are mounted on the corresponding carrier boards only.

Processor units from 1MB to 2MB are available. Any free slots must be equipped with a front side bus (FSB) terminator.
