Single Level Installation
1. Plug your USB keyboard and USB mouse into the USB console ports located on the
unit’s rear panel.
2. Depending on your console monitor’s interface, connect your monitor using one of the
following methods (see Console Monitor Connection Options, page 8), and power
on:
Note: The GCS1108 supports DVI, VGA, and dual interface monitors, but only one video
signal (DVI or VGA) can be displayed at a time – the signal will display on either the DVI
monitor or the VGA monitor, depending on the OSD settings.
See Set Computer Viedo Input, page 26 for details about setting the correct video
input and output for your video requirements.
a. One DVI monitor (DVI-I) – plug your DVI console monitor into thhe DVI console
port located on the unit’s rear panel;
b. One DVI (DVI-D + VGA) monitor – plug your dual-interface console monitor into
both the DVI and VGA console ports;
c. Two Monitors (1 x DVI; 1 x VGA) – plug your DVI monitor into the DVI console
port, and plug your VGA monitor into the VGA console port.
3. Plug your main microphone and speakers into the console microphone and speaker jacks
located on the unit’s front panel. The microphone and speakers plugged into this panel
have priority over those in the rear panel.

4. Plug your secondary microphone and speakers into the console audio ports located on
the unit’s rear panel.
5. Using the 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 and audio connectors into their corresponding USB, microphone,
and speaker sockets.
6. At the other end of the cable, plug the USB, video, microphone, and speaker cables into
their respective ports on the computer.
7. Plug your USB peripherals into the type A sockets in the USB hub section.
8. Plug the power adapter that came with your switch into an AC power source, then plug
power adapter cable into the switch’s Power Jack.
Note: Verify that all the plugs
are in the same KVM Port
sockets (all in Port 1, all in
Port 2, etc.).
9. Turn on the power to the computers.

11
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rst.
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.

12
3-Level Installation (Cascading)
The procedures for setting up a three stage installation are essentially the same as for a two
stage installation. With a three stage setup, as many as 512 computers can be controlled in
a complete installation.
Note: Switches cannot be cascaded beyond the third level.
Onceyouhavenishedcablingup(seeTwoStageInstallation,page11ifnecessary),power
up according to the following sequence:
1. For each Third Stage unit, plug the power adapter cable into the switch's Power Jack;
plug the power adapter into an AC source
2. For each Second Stage unit, plug the power adapter cable into the switch's Power Jack;
plug the power adapter into an AC source.
3. Plug the First Stage unit's power adapter cable into its Power Jack, then plug the power
adapter into an AC source.
4. Turn on the power to all the computers.
Note:ThePowerOnsequencerequiresthatallThirdStageunitsbepoweredonrst.After
they are all on, the Second Stage units must be powered on next. After all the Second
Stage units are on, the First Stage unit must be powered on. Only after all the switches
have been powered on in this sequence, can the computers be powered on.

4. If there is a next to the monitor icon,
which means that port is attached to
another KVM (Cascading). Click on a
switch number, or move the highlight
bar to it then press the right arrow key
to expand the list. Similarly, to collapse
