1.4.1 External Options
External options usually require SBus interface cards. Each system board
features three SBus slots for system expansion.
Note – An Ethernet controller is incorporated directly on the system board so
an SBus card is not needed for this function.
A monitor is not necessary for normal server operation and many servers lack
monitors. However, a TTY terminal or SPARCstation can be connected to the
server to display system messages and power-on self-test diagnostic results.
Once the server is running in auto-boot mode, the monitor can be removed.
1.4.2 Internal Options
The system contains a card cage with space for up to four system- or other type
boards. Table 1-2 summarizes the internal options for the SPARCserver 1000
system.
