1. INTRODUCTION
Thank you for purchasing the INTELLINET NETWORK SOLUTIONS™ Rackmount
Console KVM Switch, Model 521796 (15” LCD, 8-port); Model 521871 (15” LCD,
16-port); Model 523561 (17” LCD, 8-port); or Model 523578 (19” LCD, 8-port).
With a keyboard mouse, LCD panel and KVM switch module housed in an industry-
standard 19” 1U- or 2U-height rack drawer, the console saves you as much as a
third of the space needed for a rack cabinet. And when the console is cascaded
with other INTELLINET NETWORK SOLUTIONS KVM switch modules to increase
server management capacity, you save even more space.
Flip-open 15,” 17” or 19” LCD panels support VGA resolution up to 1280 x 1024
without any degradation. The advanced VGA circuit design guarantees smooth and
flicker-free switching from one computer to another with cable lengths up to 100 ft.
/ 30 m (tested with high-quality UL2919-rated, low-loss and shielded cables).
With the on-screen display (OSD) menu, you can name your computers, switch
to a computer from a list, easily configure settings and view the name of the
selected computer on-screen with a programmable time interval. Plus, the OSD
menu shows the system status throughout operation.
All KVM switch modules come with a universal CEN36 connector for connection
between the console drawer and a KVM switch module. This modularized design
offers maximum flexibility, as you can choose and swap the modules to fit your
needs. A KVM switch module can also be used as an independent KVM switch.
This user manual shows you how to set up and operate the KVM switch. (For

INTRODUCTION

Configurations
KVM switch modules are available with four, eight (Models 521796, 523561 and
523578) and 16 ports (Model 521871) with various interfaces. In applications
that require a larger number of computers, the KVM switch modules can be
cascaded in a master/slave configuration. NOTE: Throughout this user manual,
“master” refers to the KVM switch module that connects directly to the console
drawer; “slave” refers to a KVM switch module that has its console port connected
to a master’s “PC-x” port. Slaves only exist in cascade configuration.
Single KVM Switch Module Configuration:
Combined with a console, the KVM switch module
can be connected to multiple computers with
keyboard, mouse and monitor cables
as shown at right.
KVM Switch Module in Cascade
(Master/Slave) Configuration:
You can connect a second level
of one or more KVM switches
modules to a master unit.
Cascade configuration expands
system ability, allowing you to select computers connected to the master or
slaves. There is only one master that connects to the console directly operated
by a user. Once connected, the KVM switch modules automatically configure
themselves to either master or slave.
Slaves of different KVM switch
modules can be mixed in cascade
configuration as shown
here.

INTRODUCTION

2. INSTALLATION
Device Connection
Standard Models (Model 521871):
Determine the port
number of each
computer. For
computers using
a PS/2 mouse,
connect the
computer’s mouse
and keyboard
cables to the
connectors marked
with a mouse and
keyboard, respectively, as shown. Repeat this step for PC-1 through PC-8.
For computers using a serial mouse, connect the DB9-to-mini-DIN6 adapter
(included with the
switch) to the computer
mouse port, then use
PS/2 cables to connect
the mouse to the KVM
switch module.
Connect the computer’s
monitor cable to the
HD-DB-15 VGA connector.
NOTE: This function is only available for PC-7 and PC-8 marked with two mice.
Hybrid (PS/2 + USB) Models:
With a hybrid, you can connect to a computer using either a PS/2 or USB port.
To a USB computer: Use a USB A-B cable to connect from one of the PC ports
to the USB port of a computer (A connector, flat connector), as shown below.
The computer can be a USB-ready PC, Sun, HP server or Mac.
7
INSTALLATION

To a PS/2 computer: Connect a PS/2 “Y” adapter, which comes with the unit,
to the PS/2 port on the PC side, then use two mini-DIN6 male-to-male cables
for the keyboard and mouse, as shown below. There are two mini-DIN6 female
connectors on the PS/2 “Y” adapter marked for the keyboard and mouse.
NOTE: Be sure not to swap the connections.
To a laptop computer: In most cases, all you need is one PS/2 male-to-male
cable connecting the KVM switch module and your laptop, as shown below;
the “Y” adapter is not necessary. However, as some laptop computers do not
follow the industry standard, check your laptop’s user manual for details.
Slim Models (Models 521796, 523561 and 523578):
Use only the cables shown
at right. Connection from a
slim KVM module to a PS/2
computer or a USB computer
is shown below.
8
INSTALLATION
For PS/2 computers connected to
IMM and IUM models (Models
521796, 523561, 523578).
For USB computers connected to IUM
models (Models 523561, 523578).

A Module as a Slave or a Stand-Alone KVM Switch
A slave KVM switch module can be mounted to the inside of the rear uprights
of a rack cabinet using the rear
brackets (which come with all
units except IKM001), with
computer connectors facing to the
rear, as well. NOTE: The connectors
(keyboard and mouse) at the local port on the
rear of the KVM module are not applicable when
the module is connected to the TFT LCD drawer by the
CEN36 connector. When the CEN36 connector is not
connected to the TFT LCD drawer, the KVM switch module acts as a rear-mount
stand-alone KVM switch module. The VGA ports (local and remote) can be
connected to external VGA monitors at any time.
Initial Power-Up
Make sure all computers and KVM switch modules are powered down during
installation. You must power up the master before turning on any other devices.
For a single KVM switch module:
1. Connect a power adapter (output power = 12 V DC) to the master.
2. Turn on the computers.
For cascaded KVM switch modules:
1. Connect a power adapter (O/P = 12 V DC) to the master.
2. Connect power adapters (O/P = 9 – 12V DC) to all slaves.
3. Turn on the computers.
NOTE: After the initial power-up, you can hot-plug additional powered-down
computers or a slave KVM switch module without turning off already-connected
computers.
3. OPERATION
Push Buttons
A computer can be selected by pressing the push button directly, by issuing
hotkey commands or by activating the OSD (on-screen display) window. The
indicator changes to reflect the computer port selected (red). The indicator
flashes red when it is in either Auto Scan or Manual Scan mode.
NOTE: For 16-port modules (Model 521871), “1” – ”8” are for the lower row of
eight ports and “A” – ”H” are for the higher/upper row of eight ports. Port 1 and
Port A share the same button: If Port 1 is already selected, tap its button to select
9
OPERATION

Port A. If Port 1 is not selected, press and hold the “1” button on the console
panel for two seconds to select Port A. The OSD menu and hotkeys are also
available for computer selection.
K/M Reset:
K/M Reset solves most problems developed by the keyboard, the mouse,
device replacement or a change of configuration. Press both the front-panel
“1” and “2” buttons for two seconds to re-configure the whole system without
turning off either the switch module or any computer.
Auto Scan:
The KVM switch module has an easy-to-use feature to start auto-scanning. Press
both the front-panel “7” and “8” buttons for two seconds to start Auto Scan.
(For 4-port models, press “3” and “4” instead.)
On-Screen Display (OSD) Operation
By hitting the left Control key
twice within two seconds,
you’ll see the hotkey menu
if it is enabled (an OSD
option). Or, by hitting the
left Control key three times
within two seconds, you’ll
see a KVM menu showing
a list of the computers with
corresponding port numbers,
names and status.
The port number of the
selected computer is
displayed in red (as on the
console panel) at the right
corner of the OSD menu.
A device name is green if
it has power and is ready
for operation. It’s white if it
has no power. The OSD
menu updates the color
when it is activated.
Press the Page Up or Page Down keys to view another eight computers.
Use the up/down arrow keys, “1“ – “8“ or “A“ – “H“ to highlight a computer,
and the Enter key to select it. Or, press the Escape (ESC) key to exit the OSD and
remove the OSD menu from the display; the status window returns to the display
10
OPERATION

11
and indicates the currently selected computer or operating status.
A triangle mark (
4) to the right of a name indicates the port is cascaded to a
slave. The number to the left of the triangle mark shows the number of ports the
slave has; e.g., 84 for an 8-port switch. The Enter key brings you one level
down, and another screen pops up listing the names of the computers on that
slave. The name of the slave will be shown at the upper-right corner of the OSD
menu. It is useful to group computers and still be able to see the group name.
An eye icon (N) to the right of a name indicates the computer is selected to be
monitored in Scan mode. On the OSD, this icon can be switched on or off by
using the F2 function key.
Press the ESC key to exit the OSD and return to the selected computer; the computer
name is also shown on the screen.
Function Keys:
Function keys are used to access/activate a number of popular features.
F1 is used to edit the name (up to 14 characters) entered for a computer or a slave.
First, highlight a port, then press F1 followed by a name entry. Valid characters
are “A” – “Z,” “0” – “9” and the hyphen (dash) character. (Lowercase letters
are converted to uppercase.) Press the Delete (Backspace) key to delete one
character at a time. Non-volatile memory stores all name entries until you change
them, even if the unit is powered down.
F2 is used to switch the N of a computer on or off. First, use the up/down arrow
keys to highlight the computer, then press F2 to switch its eye icon on or off. If
Scan Type is “Ready PC +N,” only the active and N-selected computers will
be displayed sequentially in Scan mode.
F3 is used to lock a computer to prevent unauthorized access. To lock a device,
highlight it, then press F3. Next, enter up to four characters (as defined above)
followed by Enter as new password. A security-enabled device is marked with
a lock (œ) following its port number. To permanently disable the security function
from a locked device, highlight it, press F3, then enter the password.
To temporarily access a locked device, highlight it and press Enter. The OSD will
prompt you for the password. After entering the correct password, you are
allowed access to the device. The device is automatically re-locked once you
switch to another port. During Scan mode, the OSD skips password-protected
devices.
F4 is used to display a pop-up screen presenting additional function options,
most of which are marked with a 4 indicating there are even more options
available. Using the up/down arrow keys, select the functions and press
Enter. Available options will be shown in the middle of the screen, and can be
selected using the same procedure. Press the Escape key to exit at any time.
• Auto Scan: In this mode, the KVM switch module automatically switches from
one active computer to the next (sequentially) at a fixed interval. During Auto
OPERATION

Scan, the OSD displays the name of the selected computer. When Auto Scan
detects any keyboard or mouse activity, it suspends the scanning until the
activity stops, then resumes with the next computer in sequence. To abort
Auto Scan, press the left Control key twice, or press any front-panel button.
Scan Type and Scan Rate set the scan pattern. Scan Type (F4:More\Scan
Type) determines if scanned computers must also be N-selected. Scan Rate
(F4:More\Scan Rate) sets the display interval when a computer is selected
before selecting the next one.
• Manual Scan: This mode lets you scan through active (powered-on) computers
one by one using keyboard control. Scan Type (F4:More\Scan Type)
determines if scanned computers must also be N-selected. Press the up arrow
key to select the previous computer; press the down arrow key to select the
next computer. Press any other key to abort the Manual Scan mode.
• Audio Stick: An optional multimedia module can be linked to the back of
each KVM switch module for selecting microphone and stereo speaker
signals. There are two options for Audio Stick: “On” and “Off.” When set to
“On,” audio selection follows computer selection. When set to “Off,” audio
selection stops following computer selection. It is useful if you want to listen
to a particular computer’s audio signal while operating other computers. The
non-volatile memory stores the Audio Stick setting.
• Scan Type: This presents three further options.
“Ready PC +N” lets you scan through active and N-selected computers in
Scan mode.
“Ready PC” lets you scan through active computers in Scan mode.
“N Only” lets you scan (in Scan mode) through any N-selected computer
regardless of computer power status.
The non-volatile memory stores the Scan Type setting.
• Scan Rate: This sets the duration of a computer displayed in Auto Scan mode.
The options range from three to eight seconds. The non-volatile memory stores
the Scan Rate setting.
• Keyboard Speed: This offers a keyboard typematic setting that overrides the
similar settings in BIOS and Windows. Available speed options are “Low,”
“Middle,” “Fast” and “Faster” (10, 15, 20 and 30 characters/second,
respectively). The non-volatile memory stores the Keyboard Speed setting.
• Hotkey Menu: When you hit the left Control key twice within two seconds,
the hotkey menu appears, displaying a list of hotkey commands if the option
is on. The hotkey menu can be turned off if you prefer not to see it when the
left Control key is hit twice. The non-volatile memory stores the Hotkey Menu
setting.
• CH Display: This presents two further options.
“Auto Off” means that, after you select a computer, the port number and the
name of the computer will appear on the screen for three seconds, then
disappear automatically.
12
OPERATION

13
“Always On” means that the port number and the name of a selected computer
and/or OSD status is displayed on the screen all the time.
The non-volatile memory stores the CH Display setting.
• Position: The position of the selected computer name and/or OSD status is
displayed on screen during the operation. The choices are “Upper Left,”
“Upper Right,” “Lower Left,” “Lower Right” and “Middle.” The exact display
position varies with different VGA resolutions: The higher the resolution, the
higher the display position. The non-volatile memory stores the Position setting.
• Country Code for Sun (for Slim USB + PS/2 and Hybrid USB + PS/2 models
only: Models 523561 and 523578): Sun keyboards of different languages
have different layouts. The Rackmount Console KVM Switch is able to emulate
a Sun keyboard for a specific language type or country; e.g., Arabic, Belgian,
U.S. Select the proper country code that matches all of your Sun computers.
• Max. Resolution (for Slim USB + PS/2 and Hybrid USB + PS/2 models only:
Models 523561 and 523578): You can adjust the monitor resolution under
this sub-menu. Options are “1024 x 768,” “1280 x 1024,” “1600 x 1200,”
“1920 x 1440” and “DDC2B Disable.”
F5 (for Slim USB + PS/2 and Hybrid
USB + PS/2 models only: Models
523561 and 523578): This is to
switch the Sun mark of a port on
or off, indicating the computer is
a Sun server. Sun servers have
more keys on the keyboard than
a PC. When a Sun-marked port
is selected, the KVM switch starts
to translate the keys from a PS/2
keyboard to a Sun keyboard. See
Sun Keyboard Mapping (Section 6) for details.
ESC, or the Escape key, is pressed to exit the OSD.
Hotkey Commands
Hotkey commands are a short keyboard sequence to select a computer, to
activate a computer scan and so forth. The KVM switch module interprets
keystrokes for hotkeys all the time. A hotkey sequence starts by pressing the left
Control key twice followed by one or two keystrokes. A built-in buzzer generates
a high-pitch beep for a correct hotkey command and one low-pitch beep for an
error. A bad key sequence will not forward a command to the selected computer.
NOTE: When entering numbers, do not use the numeric keypad on the right
side of the keyboard.
The short-form hotkey command menu can be set as an OSD function (F4:more\
Hotkey Menu) to appear every time the left Control key is pressed twice.
OPERATION
PACIFIC

To select a computer by hotkey command, you need to know its port number,
which is determined by the KVM switch module connection. For a computer
connected to a master, its port is represented by the PC port label (1 – 8 or A
– H). For a computer connected to a slave, two characters represent its port.
The first character is the port number of the master unit (1 – 8); the second is
the port number of the slave (1 – 8 or A – H). Note that only a master’s PC-1
through PC-8 ports can be connected to a slave.
For example, pressing (left) Control/Control/7 selects a computer connected
to Port 7 of the master. Pressing (left) Control/Control/6/C selects a computer
connected to Port C of a slave connected to Port 6 of the master.
To start Auto Scan, which automatically scans active (powered-on) computers
one by one at a fixed interval, press (left) Control/Control/F1. When Auto Scan
detects any keyboard or mouse activity, it suspends scanning until the activity
stops, then resumes with the next computer in the sequence. The length of the
Auto Scan interval (Scan Rate) is adjustable (as explained below). To abort Auto
Scan, press the left Control key twice. NOTE: Scan Type determines whether
N-marked computers are to be displayed during Auto Scan.
Manual Scan — (left) Control/Control/F2 — enables you to manually switch
between active computers. Press the up/down arrows to select the previous or
the next computer in sequence; press any other key to abort Manual Scan.
To adjust Scan Rate — (left) Control/Control/F3 — set the duration before
switching to the next computer in Auto Scan. The KVM switch module sounds
one to four beeps to indicate the scan interval: 3, 8, 15 or 30 seconds.
To adjust the keyboard typematic rate (characters/second), press (left) Control/
Control/F4. This setting overrides that of BIOS and other operating systems.
The KVM switch module generates one to four beeps corresponding to 10, 15,
20 and 30 characters/second, respectively.
Audio Stick — (left) Control/Control/F5 — is an optional multimedia module
that can be linked to the back of each KVM switch module for selecting
microphone and stereo speaker signals. There are two options for Audio Stick:
“On” and “Off.” When set to “On,” audio selection follows computer selection.
When set to “Off,” audio selection stops following computer selection. It’s useful
if you want to listen to a particular computer’s audio signal while operating other
computers. The KVM switch module generates one (on) or two (off) beeps.
4. CASCADE CONFIGURATION
Connection
Before connecting a device (a computer or a slave KVM switch module) to the
master KVM switch module under power, you must turn off the device.
14
CASCADE CONFIGURATION

NOTE: The master must have at least as many PC-x ports as the slave; e.g.,
if an IKM108D is the master, another IKM108D can be a slave, but not an
IKM116D (see the reference on Page 5).
The ports PC-1
through PC-8
can be
connected
to either a
computer
or a slave’s
local (or console)
port, as shown at right.
The ports PC-A through PC-H can
only be connected to computers.
NOTE: Only a master’s PS/2 PC ports (not USB ports) can be connected to a
slave’s local (or console) port for cascade application.
The maximum number of computers that can
be controlled by a master/slave configuration
with all 8-port units is 64: eight
slaves, each connected to
eight computers.
OSD Menu:
After the cascade connections are complete, you should re-activate the OSD
menu to check if the master recognizes the slaves. A triangle mark (4) is placed
to the right of the channel name, indicating the port is connected to a slave and
not a computer. A number to the left of the 4 represents the slave model; e.g.,
“84” for an 8-port switch module.
Change Configuration while Running
A device (a computer or a KVM switch module) at any PC-x port can be changed
at any time after initial power-up. If you change any of the PC-1 to PC-8 ports’
connections from a computer to a slave or vice versa, or replace the devices
of a port, the OSD will update this change the next time it is activated. NOTE:
Any new device must be turned off before it is connected to the master.
15
CASCADE CONFIGURATION

5. MULTI-ACCESS MODEL
A multi-access console KVM switch (IKM2108D, IKM2116D) features a pair of
console ports, facilitating access to multiple computers from both a local and a
remote location. An example of the practicality of this feature is the ability to
access all computers in a configuration from inside a server room when you need
to physically access the computers — as when performing a software upgrade
— while being able to manage the computers outside the server room for daily
use. NOTE: The four Rackmount Console KVM Switches covered by this user
manual (INTELLINET NETWORK SOLUTIONS Models 521796, 521871,
523561 and 523578) are not multi-access models.
Connection
Connected to a TFT LCD Drawer:
The remote console is available for a second set of keyboard, mouse and
monitor.
Stand-Alone:
Both the remote and the local consoles are available for a keyboard, mouse
and monitor connection.
Operation
At power-up, the multi-access KVM switch module is in idle mode, broadcasting a
VGA signal and detecting for keyboard and mouse activity. User LEDs (A and B)
are both red, indicating the KVM switch module is not in use. When keyboard
or mouse activity is detected at one console (remote or local), the KVM switch
module immediately blocks the other console from accessing the computer. Only
one LED (remote or local), at the left side of the panel, remains lit, indicating
the KVM switch module is under user operation.
In the meantime, keyboard LEDs (Num/Caps/Scroll Lock) of the other console
start to flash as its access is denied and the monitor is blocked from a VGA signal
for security reasons. After the user has finished his operation for a period of
time (i.e., User Timeout), the multi-access KVM switch module returns to idle mode.
User Timeout has four options: “5 sec,” “30 sec,” “60 sec” and “HOLD.” Select
“HOLD” when you plan to access the KVM switch module for a long time.
Pressing Scroll Lock twice forces the KVM switch module to return to idle mode
immediately.
User Timeout is available in the OSD menu by pressing function key F4 under
the sub-menu More. NOTE: The Keyboard Speed option is not available for
multi-access models.
16
MULTI-ACCESS MODEL

6. SUN/MAC KEYBOARD MAPPING
IGM108D and IGM116D models emulate a Sun keyboard and mouse when
a computer is marked with a Sun in the OSD menu by function key F5. A Sun
keyboard has more keys than a standard PS/2 keyboard. These extra keys are
simulated by pressing the right Control key followed by one of the function keys
on the PS/2 keyboard. For example, press the right Control key, then press
function key F7 to activate Open for a Sun computer.
NOTE: For Sun, the switch module does not support the Low Power option
under Power Off Select after the command (right) Control 4.

7. TROUBLESHOOTING
Before troubleshooting any problem, ensure that all cables are properly connected
and well seated. Check that keyboard and mouse cables are not swapped. Label
and bundle the cables for each computer to avoid confusion when they’re
connected to the KVM switch module.
18
TROUBLESHOOTING
Problem
Nothing works.
VGA monitor
works fine, but
the keyboard and
touchpad don’t
work.
No screen image,
or no OSD menu.
Remedial Actions
Push the assembled drawer and the
