Occasionally, you may need to reset your system. The reset-all command resets the entire system and is similar to performing a power cycle.
If your system is set up to run the power-on self-test (POST) and initialization procedures on reset, these procedures begin executing once you initiate this command. (On some systems, POST is only executed after power-on.) Once POST completes, the system either boots automatically or enters the User Interface, just as it would have done after a power cycle.
