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
, 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 25
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
page 4); 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 150 m (500 feet).
