1 PRODUCT OVERVIEW
The Vertiv™ Cybex™ SCM Secure Desktop Matrix switch allows you to securely connect to and switch between multiple
computers at varying classification levels and allows user to simultaneously view two active computers and seamlessly
switch between computers by moving the mouse across displays called Cursor Navigation Switching (CNS). The switch
utilizes several security features to prevent the transfer of data between connected computers while allowing you to control
connected computers via a single set of peripherals. The switch supports up to eight connected computers as well as a
Dedicated Peripheral Port (DPP) for secure connection to USB peripherals including two-factor authentication devices such
as CAC smart card readers, fingerprint readers and facial recognition.
WARNING! This product is equipped with active intrusion protection and tamper-evident seals. Tampering
with the switch or breaking/removing the seals will permanently disable it and void the warranty. If the
enclosure appears to be tampered with or if all the computer selection LEDs flash sequentially, contact
Technical Support.

2.1 Control Options
LEDindicators on the front and back panels of the switch allow you to view the status of the switch and its connected
computers, monitors and peripherals. After all computers and peripherals are connected to the switch, the keyboard, mouse
and audio are mapped to computer one.
NOTE: When power is turned on to the switch, the selected channel is computer one and it appears on both the
primary and secondary monitors.
To reorder connected computers:
1. Turn off power to the switch and then to the connected computers.
2. Reconnect the computers in the desired configuration.
3. The switch should be powered off for more than one minute, then turn on power to the switch and computers.
From the front panel, you can select a channel and the monitor to display the channel. The left panel controls the display
source on the primary display and the right panel controls the display source on the secondary display.
The front panel also has keyboard LEDindicators that show the status of the device. The Caps Lock, Num Lock and Scroll
Lock indicators on the keyboard are disabled for security reasons. The symbolLEDs are illuminated to indicate that Caps
Lock, Scroll Lock and Num Lock are activated.
NOTE: When the switch is restored to factory default settings, all user-defined configurations are erased and the
keyboard and mouse are mapped to computer one. The front panel LEDs blink in unison to indicate a successful
factory reset.
2.2 Channel Selection
The numbered LED buttons are each mapped to a corresponding channel port on the back panel. For example, the LEDone
button is mapped to channel port one and the computer that is connected to channel port one. Pressing LEDbuttons 1
through 8 on the left side of the front panel shows channels 1 through 8 on primary monitor. The LEDbuttons 1 through 8 on
the right side of the front panel shows channels 1 through 8 on the secondary monitor.
When a channel is selected, its LEDbutton illuminates and the mouse cursor of the selected computer appears in the center
of the display. If the computer is connected to multiple displays, the mouse cursor appears in the center of the primary
display.
To select a channel to be displayed:
On the front panel, press the channel LEDbutton that corresponds to the computer to be displayed and the desired monitor.
To duplicate a channel on both monitors:
Press the corresponding LEDbutton of the computer to be displayed on both the primary and secondary monitors.
To lock audio functionality on a specific channel:
1. On the front panel, select the primary and secondary channels by pressing the corresponding LED buttons.
2. Select the left side of the audio lock button to lock the primary display and the right side to lock the secondary
display.
You can lock audio on a specific channel. After you lock audio functionality, you can switch channels and the audio on the
locked channel remains active.

2.3 DPP functionality
The DPP port allows secure connection to USB peripherals including two-factor authentication devices such as CAC smart
card readers, fingerprint readers and facial recognition. When a qualified USBdevice is connected to the switch, the DPP
LED is illuminated and the device is ready for use. If the USB device is compatible but not authorized for use with the
switch, the DPP status LED flashes and the device is inoperable until the device is authorized with the DPP configuration
utility. If the USB device is not compatible with the switch, the status DPP LED does not illuminate and the device is
inoperable. If no device is detected, the DPPstatus LED does not illuminate and the device is inoperable.
NOTE: When using an authentication device such as a smart card reader, do not connect any device to the switch that
requires an external power source.
When you switch channels, the USB device connected to the DPP is connected to the selected channel unless
DPPfunctionality is locked on a specific channel. When you switch to a channel that is not connected to a USBdevice, the
previous active USBconnection is terminated and no new connection is established.
You can also lock the DPP on a specific channel. When you lock the DPP, switching channels does not affect the processes
performed by the USBdevice connected to the selected channel.
To lock DPPfunctionality on a specific channel:
1. On the front panel, select the primary and secondary channels by pressing the corresponding LED buttons.
2. Select the left side of the DPP lock button to lock the DPP device to the computer selected on the primary
display.
-or-
3. Select the right side to lock to the computer selected on the secondary display.
NOTE: If the switch is restored to factory settings with DPP enabled, the DPP feature will be disabled by default after
the reboot.
See the Vertiv Cybex™ SC/SCMSwitching System AdditionalOperations and Configuration Technical Bulletin for detailed
DPP configuration procedures.
2.4 Mouse, Cursor and Monitor Settings
The mouse, cursor and monitor settings can be customized from the device's original configuration. You can reset
customized settings by executing a system reset which clears mouse and monitor characteristics and presets by pressing a
keyboard shortcut on the connected keyboard.
2.4.1 Mouse settings
Using keyboard shortcuts, you can freeze or unfreeze the mouse on a selected channel, increase or decrease the speed of
the mouse and enable or disable CNS.
To freeze the mouse on a selected channel:
Press L CTRL |L CTRL |F11 |f.
To unfreeze the mouse on a selected channel:
Press L CTRL |L CTRL |F11 |u.
To increase mouse speed:
Press L CTRL |L CTRL |F11, then press +.
2 Basic Operation 5
To decrease mouse speed:
Press L CTRL |L CTRL |F11, then press -.
2.4.2 Cursor Navigation Switching
By default, the switch is configured to use the relative mouse setting, which confines mouse cursor movement to the monitor
of the selected computer. With this setting, you must use the front panel channel selection buttons to switch between
computers.
Alternatively, the switch can be configured to use the absolute mouse setting, which allows you to move between isolated
computer systems by moving the mouse cursor across monitor borders. When the mouse cursor moves beyond the monitor
border from one computer to another, the mapping for the keyboard, mouse, audio and DPP device also changes. The
relative and absolute settings are enabled using a shortcut on the connected keyboard.
To enable the relative mouse setting:
Press L CTRL |L CTRL |F11 |b.
To enable the absolute mouse setting:
Press L CTRL |L CTRL |F11 |c.
2.4.3 Factory Reset
To clear all settings and return to the factory defaults:
Press L CTRL |L CTRL |F11 |r.
2.5 Presets
The switch includes predefined monitor layouts that you can access via keyboard shortcuts. The presets enable cursor
navigation switching (CNS) and define the layouts for two, three or four connected monitors and the location of the screen
borders.
2.5.1 Important Notes
•Always use the left control key (CTRL) unless otherwise specified.
•Keyboard shortcut keys are to be pressed sequentially.
•Do not use the numeric keypad for toggling shortcuts unless otherwise specified.
•All keyboard shortcuts refer to QWERTY keyboards. In case a non-qwerty keyboard is in use, keep using the
QWERTY layout.
•Before using any preset with a dual-head Windows computer where one video head is directly connected to a
monitor, you must download and install the KM Multi-monitor driver from the Software Downloads section of
the Vertiv website.
•To enable absolute-mouse prior to working with presets, enter: L CTRL | L CTRL | F11 | c.
NOTE: Any externally connected display should have the same native resolution of the primary display connected
directly to the switch.
To switch between the presets:
