2.2 Powering Off the Server
1. Choose a method for shutting down the server from main power mode to standby
power mode.
■ Graceful shutdown: Use a ballpoint pen or other stylus to press and release the
Power button on 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 Power/OK LED on the front panel will begin flashing,
indicating that the server is in standby power mode.
Caution – When you use the Power button to enter standby power mode, power is
still directed to the Graphics Redirect and Service Processor (GRASP) 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.
