If twoconsecutive failures are detected, the service processor displays an error code andplaces an outgoing call to notify an external party if the user has enabled this option.v Dial OutThe service processor can dial a preprogrammed telephone number in the event ofan IPL failure. The service processor issues an error report with the last reported IPLstatus indicated and any other available error information.v Update Operator PanelThe service processor displays operator panel data on the ASCII terminal if aterminal is connected either locally or remotely.v Environmental MonitoringThe service processor provides expanded error recording and reporting.v System Firmware Surveillance (Heartbeat Monitoring)The service processor monitors and times the interval between system firmwareheartbeats.v Responding to system processor commandsThe service processor responds to any command issued by the system processor.Run-time PhaseThis phase includes the tasks that the service processor performs during steady-stateexecution of the operating system.v Environmental MonitoringThe service processor monitors voltages, temperatures, and fan speeds (on someservers).v Responding to System Processor CommandsThe service processor responds to any command issued by the system processor.v Run-Time Surveillance (Heartbeat Monitoring)Chapter 7.
