6. Watch the terminal screen for error messages from the firmware diagnostic
program.
POST (power-on-self test) tests subassemblies and some interface paths
between subassemblies.
At the conclusion of testing, firmware automatically attempts to reconfigure
the system, omitting any parts of the system that have failed diagnostics.
If there are no faults, or if firmware completes a successful reconfiguration
in response to detected faults, the system boots.
Note – If faulty parts are detected and configured out of the working system,
you and the system manager must decide whether to operate the system until
replacement parts arrive, or to halt operation. Also, if a faulty component
cannot be replaced in the field, the entire subassembly (like the system board)
must be replaced.
7. To restart firmware, or if the system hangs, press the CPU reset switch on
the clock board. See Figure 3-7.
