Introduction
Overview
The KM0832 Matrix KVM Switch gives IT administrators advanced control of
multiple computers. Operators working at up to 8 keyboard, monitor, and
mouse (KVM) consoles can independently and simultaneously take direct
control of up to 32 computers. Using ATEN’s advanced video routing
technology, users can separately access up to 8,000 KVM ports in cascaded
KM0832 at the same time.
The 8 KVM consoles belonging to the first-level KM0832 are able to access all
the computers on the installation – those that are directly connected as well as
those that are daisy-chainedand cascaded. The 4 or 2 KVM consolesbelonging
to each daisy-chained KM0432 or KM0216 Matrix KVM Switch can access
the computers that are connected to them on the same daisy-chain level.
The KM0832 allows both PS/2 and USB KVM consoles to control PS/2, USB,
Sun, Mac, and serial devices. The KM0832 uses Cat 5 cables to send and
receive signals up to 300 meters between console modules and KVM adapter
cables, while Auto Signal Compensation (ASC) helps maintain high video
resolution. In addition, use of RJ-45 connectors saves precious IT real estate by
allowing a full 8 user ports and 32 KVM ports to reside in a single 1U housing.
Setup is fast and easy—plugging cables into their appropriate ports is all that
isentailed.Because theKM0832intercepts keyboardandmouse inputdirectly,
there is no software to configure, so there is no need to get involved in complex
installation routines or be concerned with incompatibility problems.
The Web-based KM0832 Administrator Utility allows users to configure the
KVM installation, account settings, and user access from anywhere, anytime.
Access to any computer is easily accomplished either by means of a powerful
menu-driven On Screen Display (OSD) system, or by entering Hotkey
combinations from the keyboard. A convenient Auto Scan feature also permits
automatic scanning and monitoring of the activities of all computers running
on the installation one-by-one.

4 Reset Button Pressing in this button performs a system reset. When the
system is reset, the KM0832 beeps, and then the KVM port
LEDs flash in succession until the reset is completed. After
the reset is completed you can login again.
Note: This button is semi-recessed and must be pushed with
a thin object — such as the end of a paper clip or a ballpoint
pen.
5UserPort1
Switch This switch selects which USER PORT 1 is active-the one on the front panel or the rear panel. Set it to FRONT to
activate USER PORT 1 on the front panel; set it to REAR to
activate USER PORT 1 on the rear panel.
6 USER PORT 1
(Maintenance
Port)
This user port is provided for convenient and easy access for
system maintenance. It shares the same function with USER
PORT 1 on the rear panel. By switching the USER PORT 1
switch to FRONT, USER PORT 1 on the rear panel is
deactivated and USER PORT 1 on the front panel is
activated. Use it just as you would any other user port. (You
must return the USER PORT 1 switch to the REAR position
to reactivate USER PORT 1 on the rear panel.)

Hardware Setup
Overview
For convenience and flexibility that allows mixing the PS/2 and USB
interfaces, the KM0832's design utilizes console modules that act as signal
translation intermediaries between the KVM consoles and the KVM switch,
andKVMadaptercables,that serveasintermediaries betweentheKVM switch
and the computers:
A separate console module is required for each KVM console; likewise, a
separate KVM adapter cable is required for each computer. The console
modules and KVM adapter cables are listed in the Cables section on page 5.
Consult your dealer to find out which console modules and KVM adapter
cables best fit your needs.

Stacking and Rack Mounting
The KM0832 can be stacked on the 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: 1. The rack mounting kit does not include screws or cage nuts for
attaching the KM0832 to a rack. If you need additional screws or cage
nuts, contact your rack dealer.
2. Allow at least 5.1 cm on each side for adequate ventilation and 12.7
cm at the rear for power cord and cable clearance.
Stacking
The KM0832 can be placed on any level surface that can safely support its
weight and the weight of the attached cables. Ensure that the surface is clean
and free of materials that can block the exhaust vents or otherwise interfere
with normal operation of the KVM switch. A foot pad set is included with the
unit. Peel the protective backing off of the foot pads, and then affix the foot
padstothebottompaneloftheKM0832atthe corners, asshowninthe diagram
