2.1.1 Switching between computers
After turning on the switch, the default channel is channel one. You can select which computer to operate
using the front panel push-buttons. The LED number illuminates to indicate which computer is currently
selected. Allow approximately one second for the video signal to sync after switching computers.
After selecting a new channel, the mouse cursor is positioned in the center of the selected computer
display. When you select a new channel, the mapping for the keyboard, mouse, audio and USB device also
changes to the specified channel.
Vertiv™ | Cybex™ SC Switching System Installer/User Guide
14
To switch between computers:
Select the computer by pressing the corresponding front panel push-button on the front of the switch.
2.1.2 Dedicated Peripheral Port (DPP)
The DPPfeature allows secure use of authentication devices such as a CAC or smartcard reader. See the
Vertiv Cybex™ SC/SCMSwitching System AdditionalOperations and Configuration Technical Bulletin for
detailed DPP configuration procedures.
The host detection function of the DPP enables you to switch between ports without disconnecting the
user authentication session, known as DPP freeze. When locked, switching channels does not affect
processes performed by the USB device connected to the locked channel. If only one computer is using
the DPP function, ensure that it is connected to channel 1.
The DPP status LED is illuminated after a qualified USBdevice is connected to the switch and ready for
use. If the USB device is not qualified or is rejected from the switch's DPPport, the DPPstatus LED flashes
and the USB device is inoperable. If the USB device is not detected by the port, the DPPstatus LED does
not illuminate and the USBdevice is inoperable.
NOTE: Do not connect a cable to the DPP if an authentication device is not needed. The switch will
automatically detect a cable and attempt to program the DPP selection logic. If you are connecting to
the DPP, your device must be fully compliant with a standard USB 1.1 or USB 2.0 and turned on.
Using DPP freeze
If you need to retain authentication information on one channel after switching to another, you can freeze
the DPP of the first channel.
To freeze the DPP channel:
1. Select the DPP channel you want to freeze.
2. On the front panel, enable the DPP freeze button and verify the channel indicator illuminates
on the selected channel and on the freeze button.
NOTE: If you are on a channel that has a DPP enabled and you switch to a channel that is not using a
DPP, then you will lose the connection and the ability to freeze the information. You must switch back
to a DPP-enabled channel to reactivate the feature.
2.1.3 KM multi-monitor support
The switches are configured to support one monitor per channel. The switch configuration must match
the physical positioning of the display units. When configuring the switch, you can select from the setup
presets or you can create a custom configuration file. To create a configuration file, see KM Configuration
on page 22.
When Virtual Display Technology (VDT)switching is enabled, you can set up a multiple monitor
configuration and seamlessly switch between displays by moving the mouse cursor to the desired display.
2 Basic Operation 15
To use the multiple monitor feature, you must download and install the KM Multi-Monitor Driver from the
Software Downloads section on the Vertiv website on each of the applicable computers.
VDTswitching
By default, the switch is configured to use the relative mouse setting, which confines mouse cursor
movement to the screen 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 display borders. When the mouse
cursor scrolls beyond the screen border from one computer to another, the keyboard, mouse, audio and
USB device mapping switch accordingly. You can enable the absolute or relative mouse settings by
pressing a keyboard shortcut on the connected keyboard. See Keyboard Shortcuts on page 19 for a list of
the keystroke combinations.
You can use the preset keys to configure the KM to support more than one monitor per channel. The
following images detail the different preset monitor configurations.
NOTE: In the configurations, gray indicates a single computer and black indicates a multi-monitor
display. P indicates the primary display and S indicates the secondary display in a multi-monitor display
configuration.

2.2 Keyboard and Mouse Settings
2.2.1 Keyboard settings
All secure switches block communication from the computers to the keyboard to prevent potential data
leaks. You can enable Caps Lock, Scroll Lock or Num Lock from a connected keyboard; however, the
connected keyboard status indicators do not illuminate to indicate the settings are enabled. The Caps
lock, Scroll lock and Num lock LEDs on the switch illuminate to indicate the settings are enabled on a
specific channel. Switching channels changes the status of the LEDs if different settings are enabled on
each computer.
Vertiv™ | Cybex™ SC Switching System Installer/User Guide
18
2.2.2 Mouse settings
When VDTis enabled, you can freeze mouse functionality on a selected channel to prevent inadvertently
switching channels if the mouse approaches the screen border. The prevent transition feature allows you
to use the mouse to move objects such as windows and icons on a screen without unintentionally
dragging the object to another display. When the prevent transition feature is enabled and the left mouse
button is depressed, you can move objects only within the active display.
Using keyboard shortcuts, you can freeze or unfreeze the mouse on a selected channel, or increase or
decrease the speed of the mouse. See Keyboard Shortcuts on page 19 for a list of the keystroke
combinations.
NOTE: The default mouse speed is set to 5 on a 1 to 10 speed scale.
2.2.3 Filtered USB port (fUSB)
Some models are equipped with a filtered USBport that only accepts authorized USB devices. When an
authorized USB device is connected to the fUSB port, the status LED on the front panel illuminates green.
When an un-authorized USB device is connected to the fUSB console port, the status LED on the front
panel illuminates red. When switching between channels, the USB device connected to the fUSB port
automatically switches. When switching to a channel that has no fUSB connection, the port remains
mapped to the last channel that had a fUSB channel. To assign the fUSB port to a specific computer,
press the freeze USB button. Freeze USB prevents the fUSB from switching even when the keyboard,
video, mouse and audio peripherals switch between computers.
2.2.4 Interchangeable KVM to KM functionality
In KVM mode one display, keyboard, mouse, USB and audio peripheral set is shared between all
computers. In KM mode, each computer is connected to a separate display while the keyboard and mouse
are shared.
To change from KVM to KM mode:
1. Disconnect the display from the KVM console port.
2. Connect each computer directly to a separate display while keeping the keyboard, mouse, USB
and audio peripherals connected to the KVM.
3. Change the mouse mode by typing L Ctrl |L Ctrl |F11 |c.
To change from KM to KVM mode:
1. Connect the display to the KVM console port.
2. Connect each computer to the corresponding KVM computer video port.
3. Change the mouse mode by typing L Ctrl |L Ctrl |F11 |b.
2.3 Keyboard Shortcuts
Keyboard shortcuts can be used to execute switch commands, load monitor presets and adjust mouse
settings. Keyboard shortcut functionality varies depending on the firmware version and the switch model.
2 Basic Operation 19
The style for sequential or concurrent keyboard shortcuts is typically Ctrl +Ctrl +F11. The following table
deviates from the style by eliminating the plus symbol between keystrokes. Unless otherwise noted, the
key combinations should be pressed concurrently and an L preceding Ctrl indicates the left control key
while an R preceding Ctrl indicates the right control key.
The following table details keyboard shortcut options.

Configuration examples
Each monitor is labeled with its computer number and monitor number in the KM configuration utility.
The monitors can be touching or separated by distance based on the geometry settings required.
After the monitors are placed into a layout, a bridge between the two monitors is shown in yellow to
indicate the mouse cursor area for switching monitors. Clicking the yellow area removes it from the
configuration and you will not be able to switch between the monitors using the mouse cursor.
Example 1
The monitor configuration in example 1 establishes a mouse cursor bridge between the bottom left corner
of display 1 and the top right corner of display 2. The mouse cursor bridge is indicated by the yellow area
and it is the only area where the mouse switching between the two monitors is enabled. When the mouse
cursor switches from display 1 to display 2, the active computer switches from computer 1 to computer 2,
respectively. The red lines indicate areas where mouse cursor switching is disabled.
Figure 2.16 Example 1 Physical Layout
2 Basic Operation 25
Example 2
Both monitor configurations in example two enable you to switch between display 1 on the left and display
2 on the right. Using the mouse cursor to switch from display 1 to display 2 also switches you from
computer 1 to computer 2.
Figure 2.17 Example 2 Physical Layout
Example 3
Example 3 depicts a multiple monitor configuration with the monitors connected at the corners. Example
3A is an invalid configuration because display 1 and display 2 do not share an overlapping area where the
mouse cursor can cross. Example 3B is valid since the two monitors overlap to create an area where the
mouse cursor can cross.

Example 4
In example 4, the physical placement of the monitors can be configured multiple ways. In the first layout,
computer 2 has two connected monitors and mouse cursor switching is enabled between computer 1 and
both computer 2 monitors. In the second layout, mouse cursor switching is enabled only between
computer 1 and display 1 for computer 2.

3 TROUBLESHOOTING
When power is turned on to the switch, it performs a self-test to verify normal operation. If the switch fails
the self-test procedure, all channel LEDbuttons flash on and off once and a combination of
LEDsilluminate. The various combinations of illuminated LEDs indicate the fault with the switch. After a
failed self-test, the switch becomes inoperable until the fault is resolved.
3.1 General
The following table lists general faults, the fault indicators and the actions to resolve each fault.
