The Normal position ( OK ):
The Normal position is used for attended operation, which is the usual or normal
placement of the key mode switch when an operator is present and in control of the
operation at the system unit. The Reset/Scroll button is active when the switch is in the
Normal position. The IPL proceeds according to the Normal Mode Bootlist.
Note: If an operating system (software) is not installed, use the Service position for initial
installation.
Attention: Pressing the Reset button when performing a reset via the remote reset port
or when the key mode switch is in the Normal position can cause data to be damaged or
lost if the operating system is running. See “Using the Reset/Scroll Button” on page 2-8
for a description of the Reset button operation.
The system unit can automatically restart if the key mode switch is in the Normal
position. When primary power is restored after a loss of power, the system unit
automatically starts again.
