About Power-On Self-Test (POST)
Diagnostics
The POST diagnostic code resides in flash PROM on the main logic board. It runs
whenever the system is turned on or when a system reset is issued. POST tests the
following system components:
■ CPU modules
■ Memory modules
■ NVRAM
■ Main logic board
POST reports its test results via LEDs located on the system keyboard and on the
system front panel. It also displays diagnostic and error messages on a console
terminal, if one is attached to the system. See “Error Indications” on page 393 for
more information about LEDs and error messages.
For information about running POST, see:
■ “How to Use POST Diagnostics” on page 373
