Run-Time Phase
This phase includes the tasks that the service processor performs during steady-state execution of the
operating system.
v Environmental monitoring
The service processor monitors voltages, temperatures, and fan speeds.
v Responding to system processor commands
The service processor responds to any command issued by the system processor.
v 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 is made before placing an
outgoing call.
