Performing Power Control Operations by using the
LOM Port
Jan 31, 2011
Through the LOM port, you can remotely perform power control operations, such as graceful shutdown and restart, power
cycling the appliance, and restarting the BMC microcontroller. A cold restart takes longer than a warm restart. In a cold
restart, you switch off power to the appliance and then switch it back on.
To perform power control operations by using the GUI
1. In the Menu bar, click Remote Control.
2. Under Options, click Power Control, and then select one of the following options:
Reset System— Gracefully restart the appliance. All operations on the appliance are stopped, no new connections to
the client or server are accepted, and all existing connections are closed before the appliance restarts. This is similar to
a warm restart, such as by entering the reboot command. The BMC does not reboot itself during this operation.
Power Off System – Immediate— Disconnect power to the appliance immediately, without gracefully shutting
down the appliance. The BMC continues to operate normally in this mode to allow the user to remotely power on the
appliance. This is the same as pushing the power button until the unit powers off.
Power Off System – Orderly Shutdown— Gracefully shut down the appliance, and then disconnect power to the
appliance. Has the same effect as pressing the power button on the back panel of the appliance for less than four
seconds. All operations on the appliance are stopped, no new connections to the client or server are accepted, and all
existing connections are closed before the appliance shuts down. The BMC continues to operate normally in this
mode to allow the user to remotely power on the appliance. This is the same as entering the shutdown command in
the appliance shell.
Power On System— Turn on the appliance. The BMC does not reboot itself during this operation. This is the same as
pushing the power button.
Power Cycle System— Turn off the appliance, and then turn it back on. The BMC does not reboot itself during this
operation. This is the same as pushing the power button until the unit powers off, and then pushing the power
button to power on the unit.
3. Click Perform Action.
Performing a power cycle of the BMC
A warm restart, cold restart, or a power cycle of the appliance, using the power button, does not include power cycling the
BMC. The BMC runs on standby power directly from the power supply. Therefore, the BMC is not affected by any state of
the power button on the appliance. The only way to power cycle the BMC is to remove all power cords from the appliance
for 60 seconds.
Performing power control operations on the BMC by using the appliance shell
When performing either a warm or cold restart of the BMC microcontroller, you cannot communicate with the LOM port.
Both actions restart the BMC but not the main CPU. To perform a warm restart of LOM from the appliance, type:
ipmitool mc reset warm
To perform a warm restart remotely from another computer on the network, type:
ipmitool –U <bmc_gui_username> –P <bmc_gui_password> –H <bmc IP address> mc reset warm
