Server Management
During normal operation, server management receives information about server status and monitors power supply voltages and operating temperature. If server management software determines that the server is not operating within specified limits, the software attempts to notify a supervisor or an administrator of the server’s condition. Server management features are implemented with the following system board microcontrollers.
Baseboard Management Controller (BMC) does the following:
∙Monitors the processor power supply voltage levels
∙Monitors then processor thermal trip and internal error signals
∙Monitors the fan sensors
∙Manages two I2C thermal sensors located near each processor
∙Manages fault resilient booting (FRB) that controls the ability to boot the server using either processor in the event of a catastrophic processor failure
Front Panel Processor (FPP) on the system board does the following:
∙Manages power, reset, and front panel NMI buttons
∙Monitors all power control sources on the front panel, server manager module, PIIX4, and RTC power control signals
An EEROM associated with the system board temperature sensor contains the following:
∙Chassis ID
∙System board ID
∙Power state
∙System board temperature
∙Intrusion detection during both power on and off conditions
