Product Overview
The GCS1716 KVM switch allows access and control up to 256 computers from a single console (keyboard,
mouse, and monitor). As many as 16 additional switches can be cascaded bringing the total number of
connected computers to 256 computers that can be controlled from a single keyboard-monitor-mouse
console. Additionally, the GCS1716 features high density SPHD 15-pin instead of the usual 25-pin connectors
thus allowing for a compact design and installation in a 1U system rack.
The GCS1716 includes one USB port located on the front panel for easy access and sharing of any USB
peripherals. Setup is fast and easy; plugging cables into their appropriate ports is all that is needed. The
switch supports both USB and PS/2 connections for the console and computers. The GCS1716 intercepts
keyboard input directly, thus eliminating the need for any software conguration. Switching between computers
can be easily accomplished either by manually pressing the front panel push button port LEDs, entering
hotkey combinations from the keyboard, or via a menu driven multilingual on-screen display (OSD) system. A
convenient auto-scan feature permits automatic scanning and monitoring of activities on all connected. Lastly,
the GCS1716 offers benets such as: a) managing multiple computers from a single console, b) eliminating
the expense of having to purchase a separate keyboard, monitor, and mouse for each computer, c) space
and energy costs savings, and d) helping create a greener environment by reducing amount of waste.

Overview
The GCS1716 is a combo switch designed to work with USB and PS/2 interfaces. It utilizes custom
KVM cables that serve as intermediaries between the switch and the connected computers. A separate
custom KVM cable is required for each computer connection. Custom cables of various lengths are listed
in the Cables section on page 5. Consult your dealer to nd out which one t your needs best.
Before You Begin
Make sure that the power to any device that you connect has been turned off. You must unplug the
power cords of any computers that have the Keyboard Power On function.
Stacking and Rack Mounting
The GCS1716 can be stacked on a desktop or rack mounted by a variety of different methods in 1U of
rack space. The procedures for each method are described in the following sections.
Note:
Allow at least 2 in (5.1 cm) on each side for adequate ventilation and 5 in (12.7 cm) at the rear for1.

otherwise interfere with the switch normal operation. Peel the protective lm off of the foot pads, and afx
the pads to the bottom panel at the corners, as shown in the diagram below.
