KM0216 / KM0432 User Manual
Cascading
Another way to expand your KVM installation is to cascade additional KVM switches from the KVM ports of the KM0216 / KM0432. Up to 16 (KM0216) or 32 (KM0432) additional KVM switches can be cascaded. As many as 128 (KM0216) or 256 (KM0432) computers can be controlled in a cascaded installation. Unlike daisy chaining, however, cascading does not increase the number of consoles that can be used to control the computers.
Note: 1. While you can daisy chain multiple KM0216 / KM0432 Matrix KVM Switches, you cannot cascade them.
2.The KM0216 / KM0432 cannot cascade KVM switches beyond the second level.
In a cascaded installation, the KM0216 / KM0432 is considered the First Stage unit; cascaded KVM switches are considered Second Stage units.
Compatible KVM switches that use the same data transfer protocol as the first stage KM0216 / KM0432 allow all of the separate switch OSDs to be integrated so that when the KM0216 / KM0432 consoles bring up the OSD, it lists all of the computers connected to all of the units. In a full cascade, 128 or 256 computers can be controlled from a single KM0216 / KM0432.
Note: The KVM switch shown in the installation diagram is the KH88. See Supported KVM Switches, page 68, for a list of KVM switches that can be cascaded from the KM0216 / KM0432.
To set up a cascaded installation, refer to the installation diagram on page 23 and do the following:
1.Power down the target device(s) that will be part of your matrix KVM switch installation.
2.Use Cat 5 cable to connect any available KVM port on the First Stage unit (the KM0216 / KM0432) to a PS/2 style KVM adapter cable (see Cables, page 5); plug the adapter cable's KVM connectors to the keyboard, video, and mouse console ports of the Second Stage unit.
Note: The distance between the Second Stage unit and the KM0216 / KM0432 must not exceed 150m (500').
