About This Manual
1 About This Manual
1.1 Scope
This manual describes how to install your KVM Extender, how to operate it
and how to perform trouble shooting.
1.2 Validity
This manual is valid for all devices listed on the front page. The product
code is printed on the base of the devices.
1.3 Cautions and Notes
The following symbols are used in this manual:
This symbol indicates an important operating instruction that should be
followed to avoid any potential damage to hardware or property, loss of
data, or personal injury.
This symbol indicates important information to help you make the best use
of this product.
This symbol indicates best practice information to show recommended
and optimal ways to use this product in an efficient way.
To ensure reliable and safe long-term operation of your KVM Extender
please note the following guidelines:
Installation
Only use in dry, indoor environments.
The KVM Extender and the power supply units can get warm. Do not
situate them in an enclosed space without any airflow.
Do not place the power supply directly on top of the device.
Do not obscure ventilation holes.
Only use power supplies originally supplied with the product or
manufacturer-approved replacements. Do not use a power supply if it
appears to be defective or has a damaged chassis.
Connect all power supplies to grounded outlets. In each case, ensure
that the ground connection is maintained from the outlet socket
through to the power supply's AC power input.
Do not connect the link interface to any other equipment, particularly
network or telecommunications equipment.
Take any required ESD precautions.
In order to disconnect the device completely from the electric circuit, all
power cables have to be removed.
Repair
Do not attempt to open or repair a power supply unit.
Do not attempt to open or repair the KVM Extender. There are no
user serviceable parts inside.
Please contact your dealer or manufacturer if there is a fault.
The KVM Extender is used to increase the distance between a source
(computer, CPU) and its console (keyboard, mouse, and other peripheral
devices).
The KVM Extender is designed for use with Cat X (Twisted Pair)
interconnect cables or fiber interconnect cables.
The KVM Extender with Cat X interconnect cables is unsuitable for
connection between buildings where a fiber optic based product should be
used instead.
The KVM Extender with fiber interconnect cables can also be used with
applications in environments which are difficult in electromagnetical
aspects. Electromagnetical interference can limit the maximum distance
und reliability.
The KVM Extender consists of at least one CPU module and one
CON module. The various modules are summarized respectively in a
vario chassis (2-fold, 4-fold or 6-fold) at CPU site and CON site (CPU and
CON unit).
The CPU module is connected directly to the source (computer, CPU)
using the supplied cables.
The CON module is connected to the console (monitor, keyboard and
mouse).
The CPU Unit and the CON modules communicate with each other
through the interconnect cables.

Description
The KVM Extenders and the provided power supply units can get warm,
for this reason an installation in closed rooms without air circulation is not
allowed. Please note that you will need at least 0.5 U (height unit) for the
ventilation above the extenders, if you mount them into racks.

The 2-fold vario chassis with an internal power supply is not equipped with
a fuse on primary side. Therefore the protection against excessive
currents has to be provided by the electrical installation of the building.

For operation with three KVM Extender CON modules and a USB 2.0
CON module in a 4-fold vario chassis, an external power supply unit at the
second 5VDC connector is explicitly necessary. In this case, redundancy
is inapplicable.
