Combined system BIOS and the Integrated BMC support provide the functionality of the various<br />
supported control panel buttons and LEDs. The following sections describe the supported<br />
functionality of each control panel feature.<br />
Note: Control panel features are also routed through the bridge board connector at location<br />
J1C1 as is implemented in <strong>Intel</strong> ® <strong>Server</strong> Systems configured using a bridge board and a hotswap<br />
backplane.<br />
7.4.1 Power Button<br />
The BIOS supports a front control panel power button. Pressing the power button initiates a<br />
request that the Integrated BMC forwards to the ACPI power state machines in the chipset. It is<br />
monitored by the Integrated BMC and does not directly control power on the power supply.<br />
• Power Button — Off to On<br />
The Integrated BMC monitors the power button and the wake-up event signals from the<br />
chipset. A transition from either source results in the Integrated BMC starting the powerup<br />
sequence. Since the processor are not executing, the BIOS does not participate in<br />
this sequence. The hardware receives the power good and reset signals from the<br />
Integrated BMC and then transitions to an ON state.<br />
• Power Button — On to Off (Operating system absent)<br />
The System Control Interrupt (SCI) is masked. The BIOS sets up the power button event<br />
to generate an SMI and checks the power button status bit in the ACPI hardware<br />
registers when an SMI occurs. If the status bit is set, the BIOS sets the ACPI power<br />
state of the machine in the chipset to the OFF state. The Integrated BMC monitors<br />
power state signals from the chipset and de-asserts PS_PWR_ON to the power supply.<br />
As a safety mechanism, if the BIOS fails to service the request, the Integrated BMC<br />
automatically powers off the system in 4 to 5 seconds.<br />
• Power Button — On to Off (Operating system present)<br />
If an ACPI operating system is running, pressing the power button switch generates a<br />
request using SCI to the operating system to shut down the system. The operating<br />
system retains control of the system and the operating system policy determines the<br />
sleep state into which the system transitions, if any. Otherwise, the BIOS turns off<br />
the system.<br />
