Clicking the IPM Device tab in the Viewing Window (shown in Figure 4-1) will display some information and functions of the system・s BMC firmware.
Device Information
This shows the revision levels of the BMC and IPMI firmware.
ACPI System Power State
This shows the managed system・s power state. If the managed system is in a power-off state, the green light will be off. This status will update automatically every five seconds.
Graceful Power Control (Administrator and Operator only)
Graceful power control will inform the OS running on the managed system to shutdown/reboot/power-cycle within a specified time (the default is 30 seconds). When the OS running on the managed system receives a graceful power control request, it will generate a pop-up window on the managed system・s monitor and start a count down. This pop-up notice window gives the user who is working on the system a chance to save any working files. However, remote login users or service users (for example Web site visitors) will not see this notice.
Graceful Shutdown: same as the shutdown function in Windows. The managed system will enter an S5 state.
Graceful Reboot: same as the reboot function in Windows.
Graceful Power Cycle: this function is a combination of the Graceful Shutdown and Power Up functions.
The Power Cycle function will shut down the managed system for a few seconds and then power up the system. Graceful power control will send an event to the System Event Log (next section). If no more memory space is left for the incoming event, graceful power control will not function.
Chassis Power Control (Administrator and Operator only)
This function is used to forcibly control the power state of the managed system・s chassis. When the BMC receives a chassis power control command, it will have direct control over the power button or reset button of a system.
Reset: this is the same as pressing the Reset button on a managed system・s chassis to reset the managed system.
Power Down: this is the same as pressing the Power button on a managed system・s chassis to remove power from the managed system.
Power Up: this is the same as pressing the Power button on a managed system・s chassis to turn on the power of the managed system.
Power Cycle: this function is a combination of the Power Down and Power Up functions.
The Power Cycle function will shutdown the managed system for a few seconds and then power up the system.
BMC Cold Reset (Administrator only)
Clicking the Cold Reset button allows you to reset the BMC. After confirming to reset the BMC, the session will break immediately. The user has to close this session manually. This function is rarely used, only in events such as when a malfunction is suspected.
