Service Processor 189
7.4.1 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 configurations tasks are completed. The
Pre-Standby phase components are:
• SP Initialization
SP performs any necessary hardware and software initializations.
• SP POST
SP conducts Power-On Self Tests on its various work and code areas.
• SP Unattended Start Mode Checks
To assist fault recovery, if unattended start mode is set, the SP
automatically reboots the server. SP does not wait for a user-input or
power-on command, but moves straight through the phase and into the
Bring-up Phase. The unattended start mode can be reset by accessing
SMS menus, or SP menus.
7.4.2 Standby Phase
The standby phase can be reached in two ways:
1. With the server OFF and power connected (the normal path), recognized
by OK in the LED display.
2. With the server ON after an operating system fault, recognized by STBY
or an 8-digit code in the LED display.
In the Standby phase, the SP takes care of some automatic duties and is
available for menus operation. The SP remains in the standby phase until a
power-on request is detected.
The Standby phase components are:
• Modem Configuration
SP will configure the modem (if installed) so that incoming calls may be
received, or outgoing calls may 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.
