Service Processor Operational Phases
This section provides a high-level flow of the phases of the service processor.
Pre-Standby Phase
This phase is entered when the server is connected to a power source. The server may
or may not be fully powered on. This phase is exited when the power-on self-tests
(POST) and configuration tasks are completed.
The pre-standby phase components are:
v
Service processor initialization - Performs any necessary hardware and software
initializations.
v
Service processor POST - Conducts power-on self-tests on its various work and
code areas.
v
Service processor unattended start mode checks - To assist fault recovery. If
unattended start mode is set, the service processor automatically reboots the server.
The 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:
v

LCD display.
v
OR
v
With the server on after an operating system fault, recognized by
STBY
or an 8-digit

available for menu operation. The service processor remains in the standby phase until
a power-on request is detected.
