2-Level Installation (Cascading)
To control even more computers, additional GCS1108 units can be cascaded from the KVM
ports of the First Stage unit. The cascaded GCS1108s that connect back to the First Stage
unit are considered Second Stage units. As many as 64 computers can be controlled in a
complete two stage installation.
Note: Plug the USB Type A connector into the upper USB port in the Console section
(they are both marked with a similar icon to remind you of the correct USB port).
To set up a two stage installation, refer to the Two Stage Installation diagram on the next
page as you do the following:
1. Make sure that power to all the devices you will be connecting up, including all preexisting
devices on the installation, have been turned off.
2. Use a custom USB DVI-I (G2L7D02UI) KVM cable set (see Cables, page 4), to connect any
available KVM Port on the First Stage unit to the Console ports of the Second Stage unit.
3. Using another custom USB DVI KVM cable set (provided with this package), plug the
DVI connector into any available DVI socket in the KVM port section of the switch, then
plug the accompanying USB Type A, microphone and speaker connectors into their
corresponding USB, microphone, and speaker sockets.
Note: Verify that all the plugs are in the same KVM Port sockets (all in Port 1, all in Port 2,
etc.), and that each socket is marked with an appropriate icon to indicate itself.
4. At the other end of the cable, plug the USB Type B, video, microphone, and speaker
cables into their respective ports on the computer.
5. Repeat steps 3 and 4 for any other computers you are connecting up.
6. For each Second Stage unit, plug the power adapter cable into its Power Jack, then plug
the power adapter into an AC source.
7. Plug the First Stage unit's power adapter cable into its Power Jack, then plug the power
adapter into an AC source.
8. Turn on the power to all the computers.
Note: The Power On sequence requires that all Second Stage units be powered on first.
After all the Second Stage units have been powered on, then the First Stage unit must
be powered on next. After the Second and First stage units have been powered on, the
computers can be powered on
.
