E-2 SPARCserver 1000 System Service Manual—June 1996
E
The system board must be installed in card cage slot 0. If the system has an
TTY console, connect it to port A of the system master. A TTY console is not
normally required if the system is in auto-boot mode (see the OpenBoot
Command Reference for instructions on enabling and disabling auto-boot).
E.2.1 Identifying the System Master
To determine which board is the system master, observe the LEDs on the
system board rear panels during boot.
•
On the system master the lower eight LEDs (yellow) cycle on and off in a
repeated pattern.
•
On other system boards the lower eight LEDs are lit in a solid pattern until
boot completes.
•
After boot ends, all LEDs (on boards with SuperSPARC® modules) will
cycle.
The system master in slot 0 must meet a set of minimum hardware
requirements, as described next.
E.2.2 Minimum Requirements for the System Master
The system master must have
•
one or two SuperSPARC modules
Two green LEDs, marked PA and PB, denote the presence of functional
SuperSPARC modules in slots A and B when lit.
•
DSBE/S or DWIS/S interface card in SBus slot 0
The DSBE/S or DWIS/S card connects to the main network and to the root
disk drive.
•
FSBE/S interface card in SBus slot 3.
The FSBE/S card connects to the SCSI tray in the top of the cabinet.
