be received or outgoing calls can be placed.
v
Dial In
Monitor incoming phone line to answer calls, prompt for a password, verify the
password, and remotely display the standby menu. The remote session can be
mirrored on the local ASCII console if the server is so equipped and the user enables
this function.

The service processor can dial a preprogrammed telephone number in the event of
an IPL failure. The service processor issues an error report with the last reported IPL
status indicated and any other available error information.

Update Operator Panel
The service processor displays operator panel data on the ASCII terminal if a
terminal is connected either locally or remotely.
v
Environmental Monitoring
The service processor provides expanded error recording and reporting.
v
System Firmware Surveillance (Heartbeat Monitoring)
The service processor monitors and times the interval between system firmware
heartbeats.
v
Responding to system processor commands
The service processor responds to any command issued by the system processor.
Run-time Phase
This phase includes the tasks that the service processor performs during steady-state
execution of the operating system.
v

The service processor monitors voltages, temperatures, and fan speeds (on some
servers).
v
