SPARCserver 1000 System Service Manual—June 1996

To identify the system master while the system is booting, look for the one
board back panel with flashing diagnostic LEDs. Figure 2-1 shows these LEDs
and the CPU LEDs. Diagnostic LEDs on all other system boards will be OFF.
After boot completes, the LED displays change:
•
all system boards with modules display the same cycling LED pattern
•
LEDs on system boards without SPARC modules are ON in a solid pattern

LEDs on System Board
The installer (or system administrator or service provider at a later time) can
change the selection of the system master, but to maintain consistency between
systems, the default selection should not be overridden.
To run POST, See Section 2.7, “Running OBP and POST.”
2.6 Connecting a Terminal to the System Master
Note – Halt the operating system before turning off system power or data may
be lost.
1. Connect a terminal to serial port A on the system master.
In UNIX, system master is identified by a cycling LED pattern 0-7 (yellow).
Note – Sun ships systems with the master board in slot 0. To be selected by
POST as master board, a system board must have at least one SuperSPARC
module, and must be the first such board located in the card cage. Install any
moduleless boards in slots 1 or higher.
