The SP monitors and times the interval between system firmware heartbeats.

The SP responds to any command issued by the system processor.
Runtime Phase: This phase includes the tasks that the SP performs during
steady-state execution of the operating system.

The SP 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.
