Chassis sis ManagementIntel® Server System "Emerald Ridge” Integrated Baseboard Management ControllerThis section provides a description of chassis management support for chassis used withServer Boards that use the Intel ® Chipset.14.1 BMC Chassis ManagementThese elements are common to the Server Chassis used for Server Boards that use the Intel ®Chipset:Power on / off button: Also serves as system shut-down to soft-power off mode (S5)request button under ACPI.System reset button.System identify button: Pressing this button toggles the state of the Chassis ID LED.Chassis ID LED: Provides a way to identify a system to be serviced, or that is in theprocess of being serviced. The LED state toggles when the system identification buttonhas been pressed. It can also be turned on and off by sending commands to the BMC.Diagnostic interrupt: Also known as the control panel NMI. It is a button with hiddenaccess.Power on LED: Also used to indicate system sleep state.System status LED: Indicates normal, degraded, non-critical, and critical conditionsdetected by the system management sub-system.Consolidated drive status LED: Located on the control panel, this LED serves twopurposes. It indicates drive activity and provides an indication when one or more fixeddrives or drives on the hot-swap backplane have a fault condition asserted.Fan Fault LED: Indicates a fan failure. It is associated with each fan. A fan fault LEDlights if the associated fan tach sensor has a lower critical threshold event statusasserted. Fan tach sensors are manual rearm sensors. Once the lower critical thresholdis crossed, the LED remains lit until the sensor is rearmed. These sensors are rearmedat system DC power-on and system reset.Global Fan Fault LED: Located on the control panel, it lights up when one or moresystem fan fault asserted.154Intel ConfidentialRevision 1.1
