Service Processor Operational Phases
This section provides a high–level flow of the phases of the Service Processor (SP).
SP Power Applied
Pre–Standby Phase
Standby Phase SP Menus Available
Bring–Up Phase SMS Menus Available
Runtime Phase AIX Login Prompt Available
Pre–Standby Phase
This phase is entered when the server is first connected to a power source. This phase is
exited when the Power–On Self–Tests (POSTs) and configurations tasks are completed.
The Pre–Standby phase components are:
• Service Processor Initialization – Service Processor performs any necessary hardware
and software initializations.
• Service Processor POST – Service Processor conducts Power–On Self–Tests on its
various work and code areas.
• Service Processor Unattended Start Mode Checks – To assist fault recovery. If
unattended start mode is set, the Service Processor automatically reboots the server.
Service Processor does not wait for user input or power–on command, but moves
through the phase and into the Bring–Up Phase. Access SMS menus or Service
Processor menus to reset the unattended start mode.
Standby Phase
The standby phase can be reached in either of two ways:
• With the server off and power connected (the normal path), recognized by OK in the LCD
display.
OR
• With the server on after an operating system fault, recognized by an 8–digit code in the
LCD display.
In the Standby phase, the Service Processor takes care of some automatic duties and is
available for menus operation. The Service Processor remains in the standby phase until a
power–on request is detected.
The Standby phase components are as follows:
• Modem Configuration
The Service Processor configures the modem (if installed) so that incoming calls can be
received, or outgoing calls can be placed.
• 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.
