5.14 Changing OS operation mode
5.14.1 What is the OS operation mode?
You must change the OS operation mode depending on whether you perform normal operation or maintenance work.
(1) Normal mode
This mode allows you to start the OS and then operate user programs such as application programs. The factory
default of the unit is normal mode.
To change maintenance mode to normal mode, specify
normal mode
for the next startup mode, and then restart the
unit.
(2) Maintenance mode
This mode allows the OS to start without starting user programs such as application programs. To change normal
mode to maintenance mode, specify
maintenance mode
for the next startup mode, and then restart the unit.
In all places marked with
maintenance mode
in this manual, you need to change the operation mode to maintenance
mode before performing the relevant operation.
5.14.2 How to change the OS operation mode
Use the OS startup mode change command (
ecmodeset
) to change the OS operation mode. The following describes
how to change the OS operation mode.
