INSTALLATION

Switch Installation – Multiple units – “RING” topology
A “RING” configuration is usually used when the users are connected to
different ServSwitch Console Plus switches and need access to all computers.
In a “RING” configuration, users on any KVM station in the ring can access all
the computers in the system on a first-come-first-serve basis.
Connect conflicts can occur with multiple users (See Appendix F)
Figure 4. Ring configuration
The Units in Figure 4 can be any ServSwitch Console Plus 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(s) from the first Unit to the
last Unit. This additional expansion cable(s) from the first Unit to the last Unit
creates the “RING”.
All Units must be equipped with an expansion card(s).
A KVM station on
Unit #3 can access
all computers.
A KVM station on
Unit #2 can access
all computers.
A KVM station on
Unit #1 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’.
