occurrence in the non-volatile System Event Log (SEL). These events include over-
temperature and over-voltage conditions as well as fan failures.
The following is a list of the major functions of the BMC:
• Access to the monitored information so system management software can poll
and retrieve the present status of the platform.
• Functions for the front-side system controls and indicators. These functions
include control of system power, hard-resets, Power LED displays, cooling fault
detection, general fault detection, and power fault LED displays. The BMC
provides this control both when the system is powered down and is functioning
on standby power only, and when the system is powered up.
• Access to the non-volatile Sensor Data Record (SDR) Repository. SDRs provide
information that the system management software uses to automatically
configure itself for the number and type of Intelligent Platform Management
Interface (IPMI) sensors in the system (e.g. temperature and voltage sensors).
• System power control
• Platform Event Paging (PEP) / Platform Event Filtering (PEF)
• Power distribution board monitoring
• Temperature and voltage monitoring
• Fan failure monitoring
• Processor presence monitoring
• Speaker 'Beep' capability on standby and when system is powered up
• Intel Itanium processor SEEPROM interface
• Processor temperature monitoring
• Hot plug PCI slot status monitoring
• Processor bus speed setting
• Chassis fan failure light control
• Chassis power fault light control
• Chassis power light control
• SDR/SEL timestamp clock
• Boardset FRU information interface
• Fault Resilient Booting (FRB)
• System management watchdog timer
• Front control panel diagnostic interrupt handling (labeled as the Init button)
• Diagnostic interrupt (Init status monitor)
• Event receiver
• System interface to the IPMB
• Secure mode control, including video blank option monitoring and control and
front control panel lock/unlock initiation.
• IPMI Management Controller Initialization Agent
• Magic Packet† and Wake on LAN† / Power on LAN support
• Emergency Management Port (EMP) interface
