Note
The UltraPort fan-out cables need to be secured or supported in case of
sudden contact or excessive weight on the cables. Please ensure that
adequate caution is taken to avoid possible damage to the UltraPort card or
Host system. This can be accomplished by securing the cables to a rack or to
the back of the server.
