8.2.1.1 Power/Sleep Button and LED Support
Pressing the Power button will toggle the system power on and off. This button also functions
as a sleep button if enabled by an ACPI compliant operating system. Pressing this button will
send a signal to the integrated BMC, which will power on or power off the system. The power
LED is a single color and is capable of supporting different indicator states as defined in the
following table.
State Power Mode
Power-off Non-ACPI
Power-on Non-ACPI
S5 ACPI
S4 ACPI
S3-S1 ACPI
S0 ACPI
8.2.1.2 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.
8.2.1.3 System Reset Button Support
When pressed, this button will reboot and re-initialize the system
8.2.1.4 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.
