Intel® Server System "Emerald Ridge” Integrated Baseboard Management Controller EPSNode Management (NM)destination and string in the BMC LAN configuration using standard IPMI commands, thenprovide the associated selectors to the BMC using the Set Node Manager Alert DestinationOEM command.9.2.3 System Information Passed to ME and POST Complete NotificationBIOS will send the BMC the following information during POST. Number of supported P-statesNumber of supported T-statesPlatform Info (data from processor MSR 0CEh)TDP value per CPUWhen the BMC detects that POST has completed, the BMC passes on the BIOS-providedsystem information to the ME. As part of this command transaction to the ME, the BMC alsoprovides the total number of installed CPUs, the Icc_TDC value for each CPU (retrieved by theBMC via PECI), and a notification that POST has completed.At system startup the ME may query the BMC for the following information using IPMI OEMcommands: Inlet air temperature reading9.2.4 ACPI Mode NotificationThe BIOS notifies the BMC when the system enters and exits ACPI mode. The BMC, in turn,notifies the ME. The NM power-limiting functionality is only available when the system isoperating in ACPI mode (an ACPI-compliant OS is running).9.2.5 Persistence across BootsData passed to the ME will persist across boots, but will not persist across AC power loss.9.3 Management Engine (ME)9.3.1 OverviewIntel ® Server Platform Services (SPS) is a set of manageability services provided by thefirmware executing on an embedded ARC controller within the IOH. This management controlleris also commonly referred to as the Management Engine (ME). The functionality provided by theSPS firmware is different from Intel ® Active Management Technology (Intel ® AMT) provided bythe ME on client platforms.Server Platform Services are value-add platform management options that enhance the value ofIntel platforms and their component ingredients (CPUs, chipsets and I/O components). Eachservice is designed to function independently wherever possible, or grouped together with oneor more features in flexible combinations to allow OEMs to differentiate platforms.9.3.2 ME Firmware UpdateThe ME FW provides a set of IPMI OEM commands for performing the FW update. An updateutility running on the host uses IPMI bridging functionality to send these commands to the MEthrough the BMC over the BMC/IPMB link.Revision 1.1Intel ® Confidential 83
