All system boards are essentially the same; no jumper changes are necessary.
System boards can be moved to any slot, especially during troubleshooting.
However, the system board in card cage slot 0 is considered the system bus
master. The minimum configuration for this board requires a SPARC® module
in location A. If a serial-interface console is used, it must be plugged into
RS232 connector A on the system master. If a color monitor is used, a color-
graphics interface card must be installed in SBus slot 1 on the system master.
Also, by convention, system boards are installed in the lowest card cage slot
numbers first. Fill all SuperSPARC module A slots before using the B slots. Fill
all group 0 SIMMs before installing any group 1 SIMMs.
For comprehensive slot assignment rules and configuration priorities, refer to
Appendix C, "General Rules for System Configuration."
