4.6 Emergency Switch-Off
In emergency situations (such as smoke or flames are coming from the server), you need to
immediately stop the use and turn off the power supply.
Caution – If smoke or flames are coming from the server, switch off all main line switches
immediately, or use the customer's distribution panel to immediately stop the power supply.
Regardless of the job at hand, remember to give top priority to fire prevention.
4.7 Cable Routing of the M8000 Server
