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.
v Unattended start mode - refer to Enable/Disable Unattended Start Mode on page
25.
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.
