V
CAUTION!
There is a risk that data may be lost.
– iRMC S4
iRMC S4 offers various options for switching the server on and off, e.g. via
the Power On Off page of the iRMC S4 Web interface.
V
CAUTION when turning the power off
(Windows Server 2012 or Windows Server 2008)!
The operation of the power switch can be specified as "Do Nothing",
"Stand by", "Hibernate", and "Shutdown" depending on the OS settings.
The default is "Shutdown".
On this server, functions corresponding to "Stand by" and "Hibernate" are
supported as BIOS and hardware functions. However, some drivers and
software installed in the server do not support these functions. For this
reason, functions corresponding to "Stand by" and "Hibernate" are
unavailable on this server. When the operating mode is set to "Stand by"
or "Hibernate", the system may operate improperly or hard disk data may
be corrupted.
For details about operating mode settings, refer to the manual supplied
with the OS.
