Pressing the reset button when the server is powered on causes a hard reset of the server.
This reset occurs after a 30-second delay, during which the server status LED flashes rapidly and the server attempts to shut down properly. Even with the delay, pressing the reset button does not guarantee a complete shutdown before rebooting. Only press the reset button when the server is powered on to recover a server which has become unresponsive. Pressing the reset button at this time may produce a dump automatically.
CAUTION:
If the server is non-responsive, see Restarting an unresponsive server. Do not pull the power cord. Pulling the power cord does not produce a dump.
