System Power-On Methods
This section discusses the following system power-on methods:
Power-on Switch
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.
Remote Power-on via Ring-Indicate Signal
The server 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 server 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.
Unattended start mode - refer to Enable/Disable Unattended Start Mode on
page 39.
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.
