Two Stage Installation
To control even more computers, up to eight additional switches can be
cascaded from the KVM ports of the CS-228. The cascaded switches that
connect back to the First Stage unit (the CS-228), are considered Second Stage
units. As many as 64 computers can be controlled in a complete two stage
installation. A table showing the relation between the number of computers and
the number of switches needed to control them is provided in the Appendix.
Note: 1. Only Master View CS-138A, CS-9138, CS-128A, or CS-124A
switches can be used with the CS-228;
2. The CS-228 does not support cascading beyond the second stage.
To set up a two stage installation, refer to the diagram on the next page and do
the following:
1. Make sure that power to all the devices you will be connecting up has been
turned off (unplug the power cords of any computers that have the
Keyboard Power On function).
2. Follow steps 1 and 2 under Single Stage Installation (see page 9).
3. Use a PS/2 KVM cable (described in the Cables section, page 4) to
connect any available KVM port on the CS-228 to the console port on the
Second Stage unit.
Repeat steps 1 - 3 for any other Second Stage units you wish to connect.
4. Use PS/2 KVM cables (described in the Cables section, page 4) to connect
any available KVM port(s) on the Second Stage unit(s) to the monitor,
keyboard and mouse ports of the computer(s) you are installing.
5. Plug in the power adapter cables for all switches on the installation.
6. Power on the First Stage CS-228.
7. Power on all Second Stage units
8. Plug in the power cords and power On all the computers.
Note: You must follow the sequence in steps 5 - 8 when powering up.
