Powering up the server
The following procedure assumes that at least one power cord is connected to the server to supply power
to the server and that the server has been previously powered on.
1.
Verify that the power cord is connected to the server and that the LEDs on the power supply unit and
front control panel are lit. The LEDs turn on immediately indicating the server is connected to power
and that the server is in a standby power state. If the power LED is off, this indicates that the server is
not connected to power or has been powered off during standby mode.
2.
Power up the server
o
Powering on locally: Press and release the power button on the front control panel.
o
Powering on remotely (BMC web interface): Log in to the BMC web interface and select power on
from the power control action list box.
o
Powering on remotely (BMC CLI): Log in to the BMC CLI and execute an IPMI power up system
command.
Powering down the server
The following procedures demonstrate how to shut down the server and verify the power status.
Shutting down the server
Graceful shutdown
To perform a graceful shutdown: Save all open files, network service, and close all applications prior
to shutting down.
Stop or terminate all necessary system processes to bring down the operating system and power off
the compute node.
Press and release the power button on the front panel of ACPI-enabled (Advanced Configuration and
Power Interface) operating systems to perform an orderly shutdown of the operating system. Servers
not running ACPI-enabled operating systems will shutdown immediately.
Emergency shutdown
CAUTION:
All applications and files will be closed without saving changes, file system
corruption might occur.
To perform an emergency shutdown, press and hold down the power button on the front panel for at least
five seconds to perform a hard shut down. The server then enters standby power mode.
BMC CLI shutdown
Log in to the BMC and execute the IPMI command to shut down the server.
