Chapter 1
Introduction
Overview
The CL5208 / CL5216 LCD KVM Switches are control units that allow access
tomultiplecomputersfromasinglekeyboard,video,andmouse(KVM) console.
A single CL5208 or CL5216 can control up to 8 or 16 computers. As many as 31
additional KVM switches can be daisy chained to the CL5208 / CL5216, so that
up to 512 computers can be controlled from a single KVM console.
The CL5208 / CL5216 offer a space-saving, streamlined approach to KVM
switch technology by integrating a keyboard, 15" or 17" LCD monitor, and
touchpad in a 1U rack-mountable sliding housing. The LCD display is built
into the cover; the keyboard and touchpad are built into the base. Slide the
KVM module section out; flip the cover up; and you are ready to go to work.
When finished, flip the cover down and slide the KVM module away.
There are eight models in the series as shown in the following table:
The CL5208 / CL5216 is built on a modular design. The KVM section can be
detached from the switch section for convenient maintenance and repair. A
special feature of the CL5208 / CL5216 Cand Dmodels is their use of DC
power instead of the AC power used by most switch products.

Your CL5208 / CL5216 investment is protected by an included Firmware
Upgrade Utility. You can stay current with the latest improvements to the
Switch by downloading firmware update files from our website as they become
available, and using the utility to quickly and conveniently perform the
upgrade.
Setup is fast and easy; plugging cables into their appropriate ports is all that is
entailed. Because the CL5208 / CL5216 intercepts keyboard input directly,
there is no software to configure; no need to get involved in complex
installation routines; nor any need to be concerned with incompatibility
problems.
Access to any computer connected to the installation is easily accomplished
either by entering Hotkey combinations from the keyboard, or by means of a
powerful, mouse driven, on-screen display (OSD) menu system. A convenient
Auto Scan feature also permits automatic scanning and monitoring of the
activities of all computers running on the installation one by one.
There is no better way to save time and money than with a CL5208 / CL5216
installation. By using the CL5208 / CL5216 with its sliding LCD console to
manage your installation, you: (1) eliminate the expense of having to purchase
a separate keyboard, monitor, and mouse for each computer; (2) save all the
space those extra components would take up; (3) save the space that a
keyboard, monitor, and mouse would take with a standard KVM switch; (4)
save on energy costs; and (5) eliminate the inconvenience and wasted effort
involved in constantly moving from one computer to another.
