Power-up Diagnostics

The CoreBuilder system automatically runs
diagnostic software at power up. This software
verifies that every component in the system is
operating correctly.
If any component fails during power-up diagnostics,
the system either fails to power up or it keeps faulty
modules offline. When the system comes up, check
to see which modules, if any, have failed diagnostics
by looking at the system configuration in the
CoreBuilder Administration Console.
During power up, the system processor LEDs provide
information on components in your CoreBuilder
system. See the illustration on page 5-3 in the
section "System Processor
System Diagnostics — LED Activity
When you first power up the system, the system
processor Power LED and Run LED are green,
indicating that the system is running diagnostics.
When the system diagnostics are successfully
completed, the Run LED blinks, indicating that the
system is operating. If the Processor LED is yellow,
the system processor has failed at power up. See
Table 5-1.
You can view messages displayed during power-up
diagnostics if you connect a terminal, workstation,
or PC with terminal emulation to the system
processor's terminal serial port.

Module Diagnostics — LED Activity
When diagnostics are running on a module, its port
status Error LEDs are yellow. When the diagnostics
are successfully completed, the port status Active
LEDs for connected ports turn green. See
If any port status Error LEDs remain yellow, the port
is not operational. If the module's Board Error LED
is yellow, the module has failed a diagnostic test.
