Call-out Test Menu
Tests the configuration after the modem is installed and configured. In order for this test to execute
successfully, at least one of the following numbers must be assigned:
v
Service center telephone number
v Customer administration center telephone number
v
Digital pager telephone number
Service Processor Parameters in Service Mode
When the system is in service mode, the following service-processor parameters are suspended:
v Unattended Start Mode
v Reboot/Restart Policy
v Call-Out
v Surveillance
When service mode is exited, the service processor functions are reactivated.
System Power-On Methods
This section discusses the following system power-on methods:
v
Power-on Switch
v Service Processor Menus
Privileged users can power on the system by selecting the System Control Power Menu option from
the main menu and then selecting the Power-on System option from the System Power Control Menu.
General users should select Power-on System on the General User Menu.
v Remote Power-on via Ring-Indicate Signal
The system automatically powers on when it detects a
″
ring indicate
″
signal from a modem attached to
serial port 1 (S1) or serial port 2 (S2).
A remote user can call the system to activate ring detection by the modem. Listen for a few more rings
than the threshold number for starting the system. The system powers on without answering the call.
v Unattended start mode - refer to Enable/Disable Unattended Start Mode on page 235.
The service processor can be enabled to recover from the loss of ac power (see Enable/Disable
Unattended Power-On Mode in the SYSTEM POWER CONTROL MENU). When ac power is restored,
the system returns to the power state at the time ac loss occurred. For example, if the system was
powered on when ac loss occurred, it reboots/restarts when power is restored. If the system was
powered off when ac loss occurred, it remains off when power is restored.
v Timed power-on - refer to the shutdown -t command on servers using AIX.
Working in conjunction with AIX, the service processor in your system can operate a timer, much like
the wake-up timer on your clock radio. You can set the timer so that your system powers on at a certain
time after shutting down. The timer is battery-operated, so power interruptions that occur while the
system is off do not affect its accuracy. Refer to the AIX shutdown -t command for details on setting
the timer.
Note: If an ac power loss is in progress when the timed power-on attempt occurs, the system cannot
power on when ac power is restored.
v Follow-up to a Failed Boot Attempt
The service processor initiates a power-on sequence if a failed boot attempt is detected (due to a
hardware or software failure).
v Fast or Slow Boot (IPL)
Using the service processor menus, you can select the IPL type, mode, and speed of your system.
