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 SPARC Enterprise
M8000 Server
In the rack space for the SPARC Enterprise M8000 server, when a 19-inch unit such
as the external I/O expansion unit mounted besides the rack-mountable dual power
feed, the cables connected to the unit must be properly routed.
This section provides an example of the cable routing when the external I/O
expansion unit mounted. Perform the cable routing properly with reference to this
section while following the precautions.
To do maintenance on the I/O Unit or the FAN unit, you need the cable routing in
the same manner. See Chapter 7 and Chapter 8.

for the SPARC Enterprise M8000 server. Follow the precautions below when routing
the cables.
