Chapter 1
Introduction
Overview
The KVM over IP Switch (CN9000/CN9600/CN9900/CN9950) is a cost-
efficient over-IP device, which allows remote access of digital video, audio and
virtual media of a PC or workstation. It enables over-IP capability by
connecting with compatible ATEN KVM switch and/or LCD console, such as
the CS1768 (8-Port USB DVI/Audio KVM Switch) or CL3800 (DVI LCD
Console).
The CN9000, CN9600, CN9900 and CN9950 respectively supports 1 VGA, 1
DVI, 1 DisplayPort and 1 4K DisplayPort video transmission, and is equipped
with a FPGA graphics processor that offers better image and video quality to
enhance user experience, while also meeting the RS-232 DTE/DCE standards
of serial control for its CPU COM and Local Console COM ports.
For user-friendly operation, an USB Mini-B port on the front panel is designed
as a Laptop USB Console (LUC) port. By simply connecting a laptop to the
LUC port, users can access any computer connected to the switch for easy on-
site management. That means no additional monitor, keyboard and mouse is
required for routine, local maintenance. Additionally, the CN9000/CN9600/
CN9900/CN9950’s Virtual Media function allows users to perform diagnostic
testing, file transfers, or apply OS/application updates and patches from a
remote console.
To ensure seamless connectivity, the CN9000/CN9600/CN9900/CN9950 is
equipped with dual LAN and dual power functionality to keep operation in the
server room smooth and efficient. The switch also supports microphone and
speakers on the local and remote console.
For ease of remote management, the CN9000/CN9600/CN9900/CN9950
supports web-friendly KVM-over-IP access with its Web Client Viewer
functionality, which is compatible with major web browsers and runs directly
off the browser without Java or browser plug-in installations. Like its Java or
Windows plug-in counterparts, it allows users to remotely access the server /
PC connected to the device, but benefiting from a more direct and simple
access option for management and operation.

Note: 1. For the list of compatible KVM switch models, please refer to the
Compatible Products section on the product web page.
2. Since there are a large number of keyboards/mouses with
functions specifically designed for OS other than Windows, they
may not be adapted and may have compatibility issue.
3. Some of the CN9000/CN9600/CN9900/CN9950’s features may
not be supported, depending on the functionality of the cascaded
KVM switch. (For example, some switches do not support virtual
media.)
