V CAUTION!
● Before switching the system unit on using the On/Off button, the
PRIMERGY BX900 S1 system unit must be connected to the power
supply for at least a minute.
● If you switch on the system unit and the connected monitor only

fully disconnect it from the mains, you must unplug the plugs from the
sockets.

environment, refer to "Safety Precautions". When operating the
device outside of this operating environment, the server may operate

responsible for any related damage, malfunction, or loss of data, etc.
