System power is off, and the BIOS has not initialized the chipset.
Mechanical is off, and the operating system has not saved any context
to the hard disk.
Mechanical is off. The operating system has saved context to the hard
disk.
DC power is still on. The operating system has saved context and
gone into a level of low-power state.
System and the operating system are up and running.
8.4.2 System ID Button and LED Support
Pressing the System ID Button will toggle both the ID LED on the front panel and the Blue ID
LED on the server board on and off. The System ID LED is used to identify the system for
maintenance when installed in a rack of similar server systems. The System ID LED can also be
toggled on and off remotely using the IPMI Chassis Identify command which will cause the LED
to blink for 15 seconds.
8.4.3 System Reset Button Support
When pressed, this button will reboot and re-initialize the system.
8.4.4 NMI Button Support
When the NMI button is pressed, it puts the server in a halt state and causes the BMC to issue
a non-maskable interrupt (NMI). This can be useful when performing diagnostics for a given
issue where a memory download is necessary to help determine the cause of the problem.
Once an NMI has been generated by the BMC, the BMC does not generate another NMI until
the system has been reset or powered down.
The following actions cause the BMC to generate an NMI pulse:
Receiving a Chassis Control command to pulse the diagnostic interrupt. This command
does not cause an event to be logged in the SEL.
Watchdog timer pre-timeout expiration with NMI/diagnostic interrupt pre-timeout action enabled.
The following table describes behavior regarding NMI signal generation and event logging by
the BMC.
