System Power-On Methods
Power-on Switch - see 'Starting the System Unit' in &ugtitle..
SP Menu power-on request
You can request a power-on via the Service Processor menus from either a local
or remote terminal.
If a remote terminal is to be used, the modem must be connected to serial port
1, and the operating system set up to enable a TTY login session on that port.
Refer to “Seamless Transfer of a Modem Session” on page D-6 for information
on transferring modem sessions from Service Processor to the operating system.
Unattended start mode - refer to Enable/Disable Unattended Start Mode on
page B-12.
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 then
current 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.
Timed power-on - refer to the
shutdown -t
command on servers using AIX.
Working in conjunction with AIX, the Service Processor in your server can
operate a timer, much like the wake-up timer on your clock radio. You can set
the timer so that your server powers on at a certain time after shutting down.
The timer is battery operated, so power interruptions occurring while the server is
off do not affect its accuracy. Refer to the shutdown -t command of AIX for
details on setting the timer.
Because of the potential for AC power loss, the Timed Power-On function of AIX
can only be assured when Unattended Power-On Mode is enabled. If a Timed
Power-On event occurs during an AC power loss, and if Unattended Power-On
Mode is enabled, the system starts when AC power is restored.
If Unattended Start Mode is disabled (the default), the system power state
remains off when AC power is restored, regardless of the power state of the
system when AC loss occurred.
Ring Indicate Power-On
Enabling ring indicate power-on disables remote call-in. If ring indicate power-on
is enabled, the server will power on at a predetermined number of rings. If the
server is already on, no action is taken. In either case, the telephone call is not
answered. The caller receives no feedback that the server powered on.
