INTRODUCTION
The RACKMUX-V15-8USB is a KVM Drawer with USB KVM Switch (RACKMUX) that combines a rackmount 15" TFT/ LCD
monitor, keyboard, touch pad, and USB KVM switch (UNIMUX) in a space-saving 1RU industrial strength drawer with wrist pads.
The RACKMUX is equipped with a built-in switch function, which allows control of up to eight USB-enabled computers with a
single keyboard, touchpad and monitor. When access to a server rack is needed, the drawer can be pulled out and the display
lifted up like a notebook computer, revealing the keyboard and touchpad. When the drawer is not in use, the display can be folded
forward and down so the 1RU drawer can be pushed into the cabinet easily and smoothly, helping to organize and streamline
busy server rooms.
The onboard USB KVM switch allows access to any Windows, MAC, or SUN USB CPUs from one monitor, USB keyboard and
USB mouse (up to 8 CPUs). Internal microprocessor circuitry allows all USB CPUs to be booted simultaneously without keyboard
error. Port selection is accomplished through On Screen Display (OSD) menus provided for switch control and security
administration.

INSTALLATION
Rack Mounting Instructions
The RACKMUX was designed to be mounted to a rack and includes mounting flanges to make attachment easy.
1. Determine the mounting height in the rack for the drawer. It should be a height comfortable to use the keyboard and see the
LCD display. Mark holes in each of the 4 corner cabinet rails at points all level with each other.
2. Secure the rear brackets to the rear rack cabinet rails. Apply the top screws (supplied) for each bracket to the holes marked in
step 1.
3. Lift the keyboard into position and line the studs on the left and right sides up with the slotted openings in the rear bracket.
Apply the nuts (supplied) to the studs but do not tighten the nuts yet.
FYI: There are 4 mounting studs provided on each side of the RACKMUX. Depending on the depth of the rack and
distance apart of the cabinet rails, the position of the rear bracket may make all 4 studs available for use. In this case,
apply the 2 nuts to the studs furthest apart from each other on each side.
4.Slide the drawer in until the top holes in the front bracket flanges line up with the holes marked in step 1. Secure the front
brackets on the drawer to the front cabinet rails with two screws per bracket. Be sure to tighten the screws securely. Then
tighten the nuts applied in step 3.
5.Apply one more screw to each of the rear brackets to finish.

USING THE UNIMUX
Once the RACKMUX is properly connected, the UNIMUX switch will enable a connection to be made between the attached CPUs
and the monitor, keyboard, and mouse.
The UNIMUX switch can be controlled by two methods:
•keyboard control through Command Mode
•mouse clicks from within some menus of Command Mode
Keyboard Control
Keyboard control of the UNIMUX switch is achieved using Command Mode - operated using the keyboard and mouse in
conjunction with OSD menus superimposed onto the monitor.
By pressing <Ctrl> + < ` > (accent key), the user can enter Command Mode. Once in Command Mode, typing a series of
commands will cause the UNIMUX switch to connect the user to any one CPU connected to the switch. Pressing the <Esc> key
will exit Command Mode. The following instruction describes how to use the menus to operate the UNIMUX switch.
OSD CONTROL
OSD superimposes a menu system on the user’s video screen with a list of all connected CPUs. OSD allows CPUs to be named
(with up to 12-character names). OSD then allows selection of CPUs by that name. Connected CPUs can be listed by name or
by port number. OSD Search Mode enables the user to type in the first few characters of the CPU's name and the OSD will locate
it. Help screens assist with all OSD functions.
Security Option
The security option of the OSD Control enables an administrator to control access to CPU ports for each user. Up to 63 users
can be created. These users have controlled access to any CPU. Only the administrator can activate or deactivate the security
features. Security can be activated from the Maintenance Mode menu (page 17) with a successful administrator login for
verification purposes. Furthermore, the administrator can set a maximum idle time value after which the current user will be
logged out and the login screen displayed. This time out does not function while the OSD is active. The current security status,
idle time out, and scan dwell time are all saved and will be restored whenever power to the switch is cycled OFF, then ON.
If the security option is enabled, when the RACKMUX is powered up the user will be prompted for a username and password to
continue. If the security option is not enabled the monitor will display the desktop image for the connected CPU and the user
can continue with normal operation of the connected CPU.
Enabling the Security Feature
To enable the security feature the administrator must first enter Command Mode from the keyboard using the sequence
<Ctrl> + <`> (accent key). The OSD menu will automatically appear on the monitor. This provides a visual way to control the
UNIMUX switch using the keyboard and mouse.
The administrator , when setting the UNIMUX switch up for the first time, may want to proceed directly to the
ADMINISTRATION Mode by typing <CTRL> +<M> , then <A>, and then <Y>.
The factory settings are:
•user name = ADMINISTRATOR
•password = ADMINISTRATOR
Note: The user name for the administrator cannot be changed from "ADMINISTRATOR".

Once logged-in, follow the instructions on pages 8 and 9 for setting up
users and changing the password. Within the Administration Mode the
administrator can setup each of the users and the limitations of their
use of the individual CPUs attached to the switch.
Figure 4- Administrator Login screen
When a standard user powers up the system a security screen will appear if security has been enabled by the
administrator. The user will need to login to the switch by following the instructions below for the USER LOGIN. If the user
does not know the appropriate user name and password (setup by the administrator), contact the switch administrator for this
information. Once logged-in a user can follow the Command Mode functions described on page 10 to control the switch within
the limitations as determined by the administrator.
User Login Mode
User login mode requires a user to login with a user name and password from the list created by the administrator. This mode will
also disable use of the front panel until the user logs in.
Function: Keystroke:
Adds a character to the
user name/password
Removes previous character
from the user name/password
Submit user name/password
Exit USER LOGIN and return
to previous mode. This function
is only available if security is
not currently active.

Broadcast Mode
To activate Broadcast Mode press <Ctrl> + <B> from the Command Mode menu.
Broadcast Mode enables the user to type characters to more computers simultaneously. From the Change Settings menu (see
page 13) the user can edit the list of ports that receive data in Broadcast Mode. A port doesn’t receive broadcast data if one of the
following conditions is true:
- the port is not in the Broadcast Mode list
- Security Mode is enabled and the user does not have access rights to the port
NOTE: The user must type somewhat slowly when in Broadcast Mode (less than 20 wpm) and cannot use the
<Backspace> key.
Scan Mode
To activate Scan Mode press <Ctrl> + <S> from the Command Mode menu.
When in Scan Mode the switch scans to each port with a CPU powered-ON. The port with the CPU powered-ON remains active
while in use until it becomes idle for the configured dwell time (default time-out period is 5 seconds) before switching to the next
powered-ON CPU port. See Command Mode section above for configuring the scan dwell time.
Note: The keyboard and mouse must remain idle for the full scan dwell time before the switch selects the next active
port.
Note: The scan dwell time set by the user only effects that user and has no effect on other switch users.
Normal Mode
When the UNIMUX switch is not in Command or Scan mode, the user is in Normal Mode, controlling the CPU to which the user is
connected through the UNIMUX switch.

Language Selection
NOTE: The LANGUAGE SELECTION option will only be accessible if the administrator is logged in.
To enter the Select Language menu press <L> from the Change
Settings menu described on page 14.
The Language Selection menu enables the user to manually
configure the UNIMUX to emulate a specific international Sun
keyboard regardless of what actual keyboard is connected. This
is recommended when the CPU needs the layout code (i.e. a
SUN CPU) and the keyboard doesn't have an explicit layout code
(i.e. Windows keyboards).
To choose a language, scroll through the menu (using either the
mouse or up/down arrows) and when the desired language is
highlighted press <Enter> on the main keyboard. The selected
language will be highlighted in red. Press <Esc> to return to the
Change Settings menu.

For more on International Sun keyboards, see page 24.
MAC Ports Configuration
NOTE: The CONFIGURE MAC PORTS option will only be accessible if the administrator is logged in.
MAC Ports Configuration menu enables the administrator to select specific ports to be connected to MAC CPUs for passing
mouse information to the MAC CPUs. This is useful when the user wants to use mouse drivers provided by the mouse vendor,
which allows the use of programmable functions for each button. Ports should be configured at installation time or whenever
necessary. After setting, the configuration is stored in non-volatile memory and will be retrieved whenever the switch is power
ON. When the port is connected to a Windows or SUN CPU, this configuration SHOULD BE DISABLED. By default, all ports are
configured as non-MAC CPUs (Windows and SUN).
NOTE: If a port is configured as connected to a non-MAC CPU, but is in fact connected to a MAC CPU, the mouse will
still work as a generic mouse. No special functions provided by software drivers will be available.
To enter the MAC Ports Configuration menu, the administrator must press <M> from the Change Settings menu, described on
page 14.
A check list with all the ports numbers preceded by a check-box will be displayed in the window.
•unchecked box = the corresponding port is set as
connected to a non-MAC CPU
•checked box = the corresponding port is set as
connected to a MAC CPU
In order to change the status of a port, the administrator has to first
select the port. The selected port is highlighted with a green bar.
To select another port, the administrator can use the arrow keys or
mouse movement. The name of the selected port is displayed at the
bottom left of the menu, right above the yellow bar.
The administrator can toggle the state of the selected check box by
pressing the <Spacebar> or clicking the left mouse button.
•Press <S> to check all the ports
•Press <C> to uncheck all the ports
