Sun Enterprise 6500/5500/4500 Systems Reference Manual

CPU Modules

  1. Each CPU/Memory+ board has two sets of CPU connectors, marked "PROC 0" and "PROC 1".

  2. Do not mix CPU speeds.

  3. Requirement-To run 250 MHz CPU modules: (1) use only clock+ board part number 501-4286 and (2) do not mix 250 MHz CPU modules with CPU modules of a different speed.

  4. The order in which CPU slots are filled is not critical. However, to optimize heat dissipation in the system:

Table D-1 shows slot locations for an example of five CPUs on three CPU/Memory+ boards.
