SmartView XPro Installation and Use Page 32
Creating entries for computers connected to cascaded SmartViews
You can cascade SmartView 4XPro units using one, two, three or four KVM links
and SmartView 2XPro units using one or two KVM links. Section 2.5 explains the
rules that you must follow when installing a SmartView cascade. The number of
cascade links that you install determines the number of simultaneous users that can
access computers on the cascaded SmartViews. Ideally if you are cascading 4XPro
units then you should use four cascade links as this will cause no blocking and will
allow all four users simultaneous access to all computers.
Each computer name that you add to the on-screen menu has an associated port
number that tells the SmartView where to find the computer. Port numbers for
computers attached to a single SmartView are simply the port number that the
computer is attached to. Port numbers for computers connected to cascaded
SmartViews are constructed by defining the port routing that is required to get from
the user's KVM to the computer.
Figure 7 illustrates how port numbers are constructed and how the physical
configuration of a cascaded system relates to entries in the on-screen menu. The
illustrated configuration is an unlikely configuration in practice but has been chosen
for explanation purposes. If you make multiple cascade links then they must be
connected to the groups of ports defined in figure 8. These ports have associated
group port numbers. The SmartView uses this group port number to connect to the
first available port in that group. For example, group port number 21 comprises of
ports 1 and 2. If these ports are linked to a cascaded SmartView and users try to
connect to computers that are attached to the cascaded SmartView, the system will
allocate the cascade links to the first two users on a first come first served basis.
Further users that try to connect to computers on the cascaded SmartView will get a
message saying that no cascade links are available and they will not be able to
connect to the cascaded SmartView until one of the previous users has finished with
one of the cascade links.
