38 Board Set Description
39MAXDATA PLATINUM 90004R Server System
Server Management
The server management features are implemented using two micro controllers: the Baseboard
Management Controller (BMC) on the I/O board and the QLogic GEM359 SCSI hot-swap controller
on the SCSI backplane board. The ICMB controller is integrated in the BMC and provides an interface
to the external ICMB via the ICMB board.
The rmware for the BMC of each micro controller is eld-upgradeable using the Firmware Update
utility. For information on the Firmware Update Utility, refer to “Running the Firmware Update Utility”
The GEM359 rmware can be updated using a separate utility.
Baseboard Management Controller (BMC)
The Baseboard Management Controller (BMC) and its associated circuitry reside on the I/O riser card.
The BMC autonomously 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 pole 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 congure 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
• Platform Event Paging (PEP) / Platform Event Filtering (PEF)
• Power distribution board monitoring
• Temperature and voltage monitoring
• Fan failure monitoring
• Processor presence monitoring (no processors installed)
• Interlock monitoring
• Speaker ‘Beep’ capability on standby and when system is powered up
• Intel
