System / Processor - Board Component Locations (Netfinity 5500 - Type 8660)


  Turn off the server, and disconnect the power cords before moving any jumpers


  Be sure the microprocessor bus-to-core fraction is set correctly.
For example, if you have a 350 MHz microprocessor installed and the system bus speed is 100 MHz (the default), be sure that the jumpers are set to a bus-to-core fraction of 3.5 (350/100).
Refer to jumpers J27-J30 in the Core/Bus Ratio  table below.


  If installing or changing to a different speed processor than the original processor, be sure to change the processor core-frequency selection jumpers on the processor board.
If the microprocessor bus-to-core fraction (see below Core/Bus Ratio  table ) is incorrect, system board components will overheat and component damage might occur..
