Switch Installation – Multiple units – “RING” topology
A “RING” configuration is usually used when a user needs access to all
computers from different KVM stations. In a “RING” configuration, a
user on any KVM station in the ring can access all the computers in the
system. Connect conflicts can occur with multiple users unless model
UC2-1X16U/E is used for unit #2 or #3. (See Appendix F)
Figure 4. Ring configuration
The Units in Figure 4 can be any UltraConsole model
The “RING” installation procedure is very similar to installing a “BUS”
configuration with the exception of removing jumper JP1 on the
expansion cards on two Units and adding an expansion cable from the
first Unit to the last Unit. This additional expansion cable from the first
Unit to the last Unit creates the “RING”.
A KVM station on
any Unit can
access all
computers.

In the example used in Figure 4, removing jumper JP1 on Unit #1
and #3 divides the total ring cable length approximately in half.
Unit #3 (IN) to Unit #1 (OUT) = 20’
Unit #3(OUT) to Unit #2 (IN), Unit #2 (OUT) to Unit #1 (IN) = 20’.
