Using the Service Processor
• Menus
The Service Processor menus are password–protected. Before you can access them,
you need either the General User password or the Privileged User password.
Bring–Up Phase
This phase is entered upon power–on, and exited upon loading of the operating system.
The bring–up phase components are as follows:
• Retry Request Check
The Service Processor checks to see if the previous boot attempt failed. If the specified
number of failures are detected, the Service Processor displays an error code and
places an outgoing call to notify an external party if the user has enabled this option.
• Dial Out
The Service Processor can dial a preprogrammed telephone number in the event of an
boot failure. The Service Processor issues an error report with the last–reported boot
status indicated and any other available error information.
• Update Operator Panel
The Service Processor displays Operator Panel data on the ASCII terminal if a remote
connection is active.
• Environmental Monitoring
The Service Processor provides expanded error recording and reporting.
• System Firmware Surveillance (Heartbeat Monitoring)
The SP monitors and times the interval between system firmware heartbeats.
• Responding to System Processor Commands
The SP responds to any command issued by the system processor.
Runtime Phase
This phase includes the tasks that the Service Processor performs during steady–state
execution of the operating system.
• Environmental Monitoring
The Service Processor monitors voltages, temperatures, and fan speeds.
• Responding to System Processor Commands
The Service Processor responds to any command issued by the system processor.
• Run–Time Surveillance (Heartbeat Monitoring)
If the device driver is installed and surveillance enabled, the Service Processor monitors
the system heartbeat. If the heartbeat times out, the Service Processor places an
outgoing call. This is different from the bring–up phase scenario, where the specified
number of reboot attempts are made before placing an outgoing call.
