NTI RACKMUX-4K17 RACKMOUNT 4K LCD MONITOR WITH KEYBOARD AND MOUSE
INTRODUCTION
The RACKMUX-4K17-N Drawer (RACKMUX®) consists of a Keyboard, Touchpad, and 4K LCD monitor integrated into a
1RU rack-mountable drawer with wrist pads. 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 mouse. 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 NTI RACKMUX product line offers a range of KVM Drawer solutions ideal for rack and server
management applications, which will ensure reliability and serviceability.
The keyboard and mouse interface is compatible with Windows platform CPUs. This multiple interface capability reduces
equipment costs by ensuring that a single console is compatible with various PC/server input devices.

INSTALLATION
Rack Mounting Instructions
If you would like to see a video of this installation, see the “single-person-installation”video .
1. Locate and unpack the hardware bag. Your hardware bag will include all items necessary to install the specific RACKMUX
model (see the manual that accompanied your RACKMUX drawer), including the following hardware unique to the Single-Person
hardware installation:
10- #10-32 cage nut
2- #10-32 x 1/2” flat-head machine screw
8- #10-32 x 3/4” pan-head machine screw
To install the rails you will need only a tape measure and Phillips screwdriver.
2. Unpack the left and right rail assemblies. Each are labeled “Right Front” and “Left Front” to indicate their intended position and
orientation. Extend each rail assembly to the dimension required for your rack. Rail assemblies are adjustable to fit within a rack
between 24” and 40” in depth.
Rail assemblies are adjustable in length from 24” to 40”.

4. Install the right rail assembly. The end with the label “Right Front” mounts to the front rack support. Install only the center
screw through the rail flange to the rack support and cage nut using the #10-32 x 1/2” flat head machine screw provided. (See
image below.) Do not tighten at this time. Install the left rail assembly in the same fashion. The end with the label “Left Front”
mounts to the front rack support.
5. Install two #10-32 x 3/4” pan-head screws in the rear of each rail assembly as shown below. Do not tighten at the time.

Note: To provide sufficient room for the LCD monitor to be opened to a proper viewing angle (a minimum 90 degree
position from the keyboard), ensure that all devices mounted above the RACKMUX extend no more than 1.75” from the
rack frame. (See Figure 7)

Optional Telco 2-Post Mounting
If the Telco 2-post mounting bracket kit (NTI# RL-T15-TEL)is to be used, secure the short and long brackets to each side of the
drawer as shown in Figure 8. Apply 2 nuts (supplied) per bracket to secure the brackets to the drawer. Apply two #10-32x3/4”
screws (supplied) per bracket to the post at the desired height. Slots are provided in the brackets to make minor depth
adjustments easy. Be sure to properly tighten all nuts and screws before using the drawer.

Connect to a CPU
Connect the RACKMUX to a USB CPU with either an HDMI or Display Port type video port. For connection to a USB CPU with
HDMI video port, use the HD-6-MM and USB2-AB-2M-5T cables supplied as shown in Figure 9. Longer cables are available
(see page 1).
Figure 9- Connect a CPU
Connect Extra Device
On the front of the RACKMUX is an additional USB Type A port to be used, if desired, for an extra accessory. Any low or full
speed USB device may be connected to this port to be used. This port is fully compliant with USB standard 2.0 and earlier.
Note: In order for the optional USB device port to be usable, the USB port on the rear of the RACKMUX must be
connected to a USB enabled CPU (a 2 meter USB cable is supplied).
Note: If a USB keyboard or mouse is connected, operation of the RACKMUX keyboard or mouse may cause
unpredictable results. Do not try to use both mice or both keyboards at the same time.

DISPLAY FUNCTIONS
An NTI RACKMUX with a 17” monitor supports resolutions up to 3840 x 2160 @ 30Hz (1080p @ 60Hz). The quality of the image
on the LCD monitor is adjustable using an On Screen Display (OSD) menu using the control buttons on the RACKMUX.
Standard Controls
The RACKMUX has 5 standard control buttons and a power LED. The 5 standard control buttons operate as follows:
The Power button turns the RACKMUX LCD Monitor and backlight ON and OFF as desired.
The Power LED located immediately to the left of the Power button is a dual color LED. It will illuminate with a green color
when the RACKMUX is powered ON and has video sync. It will illuminate with a red color if the RACKMUX is powered ON
but there is no input signal detected.
The Menu/Select button is used to bring up the OSD menu where the various settings of the LCD display can be adjusted.
Once the OSD screen is displayed, the Menu/Select button is used to make selections within the menus. See "OSD
Control Menu" (below) for more on LCD display settings.
The Up and Down Arrow buttons are used to navigate through the menus. Move the cursor up or down as desired to
highlight an item for selection. Once an item is highlighted, pressing the Menu button will select it.
The Exit button will exit the OSD menu when visible.
OSD Control Menu- 17.3 Inch Hi-Definition 4K Monitor
The OSD (On Screen Display) Menu enables the user to select the desired characteristics of the LCD display. To activate the
OSD Menu, press the Menu button (below). To turn the Menu back OFF, either press the Exit button or just wait
approximately 10 seconds (timing is adjustable) and it will automatically be cleared from the screen. Any changes made before
exiting the menu will be saved.

OSD Main Menu
The Main Menu is broken into eight sections, Input Source, Brightness/Contrast, Color, Picture Quality, Display, Audio, Multi-
Window and Other (Misc). Press one of the arrow buttons to move between them. To select a menu and move to
characteristics within them (i.e. VGA, DP or HDMI2.0 under the Input Source menu), press the Select button while the desired
menu is displayed.
Note: If only one input connector is used, the input source will automatically switch to the active connector. No user
selection will be necessary.
If both input connectors are used, as of this publication, to use a DisplayPort source select "HDMI2.0", and to use
an HDMI source select "DP".
Images of the other menus are provided on the following pages for your reference.
Press the Exit button or select “Exit” to exit the OSD menu.
