3.1.3Power 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.
