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 3–3.
