Graceful shutdown: Press and release the recessed Power button on the upper left-hand side of the front panel. This causes Advanced Configuration and Power Interface (ACPI)–enabled operating systems to perform an orderly shutdown of the operating system. Servers not running ACPI–enabled operating systems will shut down to standby power mode immediately.
Emergency shutdown: Press and hold the Power button for four seconds to force main power off and enter standby power mode.
When main power is off, the LED is not lit.
Caution - When you use the Power button to enter standby power mode, power is still directed to the service processor board and power supply fans, indicated when the Power/OK LED is flashing. To completely power off the server, you must disconnect the AC power cords from the back panel of the server.
The following illustration shows the recessed Power button on the upper left-hand side of the system front panel.
