SBus Cards

1. Install double-wide SBus cards only on the SBus+ I/O board in SBus slots 1 and
2. The location of SBus slot 0 prevents its use with double-wide cards.
2. Double-wide SBus cards cannot be used with the Graphics+ I/O board. The
middle card connector does not fit SBus cards.

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. The order in which you fill CPU slots is not critical. However, to optimize heat
dissipation in the system:

Fill all PROC 0 locations on all CPU/Memory+ boards before filling any PROC
1 locations. To receive the maximum quantity of diagnostic information, fill
PROC 0 on board 3.
After all PROC 0 locations are filled, you can begin filling the PROC 1
locations, again starting from the lowest slot number to the highest.
