Platform Description Server Management The Baseboard Management Controller (BMC) monitors system platform management events and logs their occurrences in the non-volatile System Event Log (SEL). This includes events such as over-temperature and over-voltage conditions, and fan failures. The BMC can also provide the interface to the monitored information so system management software can poll and retrieve the present status of the platform. The BMC also provides the interface to the non-volatile Sensor Data Record (SDR) Repository. Sensor Data Records provide a set of information that system management software can use to automatically configure itself for the number and type of IPMI sensors (such as temperature and voltage sensors) in the system. The following is a list of the major functions of the BMC: System power control (including providing Sleep/Wake push-button interfaces for ACPI Platform Event Paging (PEP) / Platform Event Filtering (PEF) Monitoring: - Power distribution board monitoring - Temperature and voltage monitoring - Fan failure monitoring - Processor presence monitoring (no processors installed) and processor temperature monitoring - Interlock monitoring Processor core ratio speed setting Speaker beep capability on standby and when system is powered up Hot-plug PCI slot status reporting Chassis control: - General fault light control - Chassis cooling failure light control - Chassis power fault light control - Chassis power light control - Chassis ID LEDs control System Event Log (SEL) interface Sensor Data Record (SDR) repository interface SDR/SEL timestamp clock Board set FRU information interface Fault resilient booting System management watchdog timer Front panel system diagnostic-interrupt handling Platform Management Interruption (PMI) / System Diagnostic Interrupt (SDI) status monitor Event receiver System interface to the IPMB (via system interface ports) IPMI Management Controller Initialization Agent (MCIA) Emergency Management Port (EMP) interface Serial/modem and LAN alerting 54 Intel® Server Platforms SR4850HW4 & SR4850HW4/M Product Guide
