2.2 Powering Off the Server
You can use one of the methods for shutting down the server from main power mode
to standby power mode.
1. Graceful shutdown : Use a non-conducting pointed object, such as a 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.
2. Emergency shutdown : Press and hold the Power button for four seconds to force
main power off and enter standby power mode.
3. ELOM or ILOM web interface : Log in to the web interface and use the Remote
Power Control screen to perform a graceful power off of the server.
4.
ELOM or ILOM command-line interface (CLI)
: Log in to the ELOM or ILOM CLI
and use the following command:
–>
stop /SYS
For more information about controlling server power from the web interface or
CLI, see the corresponding SP documentation collection.
5. To completely power off the server, you must eject it from the chassis power
connector or remove power from the chassis. See “To Remove the Server Module
From the Chassis” on page 3-13 or your chassis documentation for details.
Note – When you use the Power button to enter standby power mode, the system
continues to supply power to the SP and the power supply fans, and the Power/OK
LED blinks.
When main power is off, the Power/OK LED on the front panel blinks, indicating
that the server is in standby power mode.
