3.1.3 Power Off with Windows
If a power supply is turned off without shutdown of Windows, the data in a hard disk is
destroyed and it may be unable to reboot.
Model 2000 is supporting the automatic shutdown of Windows, and the power supply
off-sequence. If the power supply module of exclusive use is used, the shutdown of
Windows can be performed without carrying out operation of a mouse and a keyboard.
Important
• In order to use an automatic shutdown function, the RAS support software installed
in C2 as standard is required.
