Processor Upgrade - NEC PowerMate Professional 9000E Series User Manual

Processor Upgrade

The system can accommodate two Pentium II processors.
Each Pentium II processor is packaged in a Single Edge
Contact (S.E.C.) cartridge. The cartridge includes the
processor core with an integrated 16 KB primary (L1) cache;
the secondary (L2) cache; a thermal plate; and a back cover.
The system board has two S.E.C. cartridge Slot 1 242-pin
edge connectors. When the processor is inserted, the VID
pins program the voltage regulator on the system board to the
required voltage for the processor. The processor is secured
to the connector in a retention mechanism.
Incorrect installation of the processor can
damage the processor, system board, or both.
Follow the installation instructions carefully.
The system requires a heatsink on the
processor. Verify that you have the correct
heatsink for the processor being installed.
When upgrading the processor, first remove the processor
currently installed in the system, then install the upgrade
processor.
