For example, if the chassis ID LED is blinking and thechassis ID button is pressed, then the chassis ID LED changes to solid on. If the button ispressed again, then the chassis ID LED turns off.3.5.4 LCD Panel: Intel ® Local Control PanelIntel ® Local Control Panel (LCP) is not supported on this platform.3.5.5 Front Panel / Chassis InputsThe BMC monitors the front panel buttons and other chassis signals. The front panel inputbuttons are momentary contact switches that are de-bounced by the BMC’s integrated hardware.The de-bounce time is 8 ms. BMC debouncing does not affect the operation of the power orreset button, since the power and reset buttons are connected to the chipset. The debouncing isonly for BMC monitoring.3.5.5.1 Chassis IntrusionEmerald Ridge Support a chassis intrusion sensor.. The BMC monitors the state of the Chassis Intrusion signal and makes the status of the signalavailable via the Get Chassis Status command and the Physical Security sensor state. Achassis intrusion state change causes the BMC to generate a Physical Security sensor eventmessage with a General Chassis Intrusion offset (00h).The BMC detects chassis intrusion and logs a SEL event when the system is in the on, sleep, orstandby state. Chassis intrusion is not detected when the system is in an AC power-off (AC lost)state.The BMC hardware cannot differentiate between a missing Chassis Intrusion cable or connector,and a true security violation. If the Chassis Intrusion cable or connector is removed or damaged,the BMC will treat it as if the chassis cover is open, and take the appropriate actions.System fans can be set to boost to maintain proper system cooling when a chassis intrusion isdetected. Please see the fan speed control sensor data records in Table 82 for more information.3.5.5.2 Power ButtonSee Section 3.1.5.3.5.5.3 Reset ButtonAn assertion of the Front Panel Reset signal to the BMC causes the system to start the resetand reboot process, as long as the BMC has not locked-out this input. This assertion isimmediate and without the cooperation of software or the operating system.See Section 3.3.3 for more information.3.5.5.4 Diagnostic Interrupt (Front Panel NMI)A diagnostic interrupt is a non-maskable interrupt or signal for generating diagnostic traces andcore dumps from the operating system. The diagnostic interrupt button is connected to the BMCRevision 1.1Intel ® Confidential 17
