Using The Reset/Scroll Button - IBM R30 Operator's Manual

Using the Reset/Scroll Button

Attention: When the key mode switch is in the Normal or Service position, pressing the
Reset/Scroll button causes the unit to reset and do an initial program load (IPL). Pressing
the Reset/Scroll button while the operating system is running can result in damaged or lost
data.
The Reset/Scroll button is used to:
Reset the system unit and cause an IPL when the mode switch is set to Normal or
Service.
Read out messages (scroll) after a flashing 888 is displayed.
Start the dump program when a manual dump is needed.
Sequentially read system configuration in Stand-By Mode and with the key mode switch
in Service position.
Pushing the Reset button once causes an incomplete reset and the system may not restart.
Therefore it is recommended that you push it twice for a complete reset.
When the mode switch is in the Secure position, the Reset/Scroll button is disabled, and you
cannot perform an IPL by pushing the Reset/Scroll button.
