Figure 17 Connected and Isolated 10Mbps Segments (Logical View)
100Mbps segment connected to Cascade Allows you to connect
or isolate the 100Mbps segment from the 100Mbps cascaded
segment that is connected to other units in the stack. Figure 17
shows an example of connected and isolated 10Mbps segments.
Isolating the segment (unchecking the checkbox) means that
100Mbps traffic received by the unit is not passed on to other units
in the stack (unless it is passed on by the 10Mbps segment, if that
segment is not isolated and the unit's segment switch is operational).
Set Switch Mode To AutoConfigure / Off
Specifies whether you want the unit's internal switch to be
automatically configured by the stack or disabled. If set to
'AutoConfigure', the switch may be active or inactive depending on
the configuration of other units in the stack.
There can only be one active switch linked to the stack's cascaded
segments, in order to avoid a network loop.
