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.
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 DPP feature allows secure use of authentication devices such as a CAC or smartcard reader. Vertiv Cybex™ SC/SCM Switching System Additional Operations and Configuration Technical Bulletin for detailed DPP configuration procedures.
The host detection function of the DPP enables you to switch between ports without disconnecting 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 the DPP function, ensure that it is connected to channel 1.
The DPP status LED is illuminated after a qualified USB device is connected to the switch and r use. If the USB device is not qualified or is rejected from the switch's DPP port, the DPP status and the USB device is inoperable. If the USB device is not detected by the port, the DPP status not illuminate and the USB device is inoperable.
NOTE: Do not connect a cable to the DPP if an authentication device is not needed. The s automatically detect a cable and attempt to program the DPP selection logic. If you are conn the DPP, your device must be fully compliant with a standard USB 1.1 or USB 2.0 and turn
Using DPP freeze
If you need to retain authentication information on one channel after switching to another, you can the DPP of the first channel.
To freeze the DPP channel:
- Select the DPP channel you want to freeze.
- On the front panel, enable the DPP freeze button and verify the channel indicator illumin 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 DPP, then you will lose the connection and the ability to freeze the information. You must s 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 m the physical positioning of the display units. When configuring the switch, you can select from the presets or you can create a custom configuration file. To create a configuration file, see KM Configuration on page 15.
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 user.
To use the multiple monitor feature, you must download and install the KM Multi-Monitor Driver f Software Downloads section on the Vertiv website on each of the applicable computers.
VDT switching
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 par selection buttons to switch between computers.
Alternatively, the switch can be configured to use the absolute mouse setting, which allows you to between isolated computer systems by moving the mouse cursor across display borders. When the cursor scrolls beyond the screen border from one computer to another, the keyboard, mouse, audio 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 13 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 following images detail the different preset monitor configurations.
NOTE: In the configurations, gray indicates a single computer and black indicates a multi-monit display. P indicates the primary display and S indicates the secondary display in a multi-monit 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 leaks. You can enable Caps Lock, Scroll Lock or Num Lock from a connected keyboard; however, connected keyboard status indicators do not illuminate to indicate the settings are enabled. The C: lock, Scroll lock and Num lock LEDs on the switch illuminate to indicate the settings are enabled specific channel. Switching channels changes the status of the LEDs if different settings are enabled each computer.
2.2.2 Mouse settings
When VDT is enabled, you can freeze mouse functionality on a selected channel to prevent inadve switching channels if the mouse approaches the screen border. The prevent transition feature allows to use the mouse to move objects such as windows and icons on a screen without unintentional dragging the object to another display. When the prevent transition feature is enabled and the left 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 decrease the speed of the mouse. See Keyboard Shortcuts on page 13 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 USB port that only accepts authorized USB devices. When authorized USB device is connected to the fUSB port, the status LED on the front panel illuminates when an un-authorized USB device is connected to the fUSB console port, the status LED on the 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 are shared.
To change from KVM to KM mode:
- Disconnect the display from the KVM console port.
- Connect each computer directly to a separate display while keeping the keyboard, mouse, and audio peripherals connected to the KVM.
- Change the mouse mode by typing L Ctrl | L Ctrl | F11 | c.
To change from KM to KVM mode:
- Connect the display to the KVM console port.
- Connect each computer to the corresponding KVM computer video port.

The KM configuration utility is a web-based tool that allows system administrators to define custom monitor setups in a KM configuration file. The file is saved with the .kmc extension. When configuring a KM switch using a KM configuration file, you must be logged in to the switch as administrator.
The KM configuration utility allows administrators to define the number of monitors connected to each computer. Monitors can vary in size and resolution, and can be arranged in multiple layouts. You must download and install the KM configuration utility from the Software Downloads section on the Vertiv web site.
The KM configuration utility operates only with Microsoft® Windows®. Before downloading and installing the KM configuration utility, ensure at least Microsoft® Windows® XP is installed on the computers to be connected. The following browsers support the KM configuration utility:
• Google Chrome 20.0 or higher
• Microsoft® Internet Explorer®
- Mozilla® Firefox®
Before creating a KM configuration file, verify the number of computers and monitors to be connected to the KM switch and the monitors' sizes and resolutions.
2.4.1 Creating a KM configuration file
A KM configuration file is referred to in the KM configuration utility interface as a KM configuration project. Each customized setup requires its own project. You can create projects using the KM configuration utility project wizard. After completing the steps in the wizard, the KM configuration file is generated and downloaded to the computer.
The following table lists guidelines for entering project file information.
| CONFIGURATION FIELD | DESCRIPTION |
| Project Name | Name of the custom monitor configuration. |

Configuration examples
Each monitor is labeled with its computer number and monitor number in the KM configuration u. 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 yel 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 of display 1 and the top right corner of display 2. The mouse cursor bridge is indicated by the and it is the only area where the mouse switching between the two monitors is enabled. When cursor switches from display 1 to display 2, the active computer switches from computer 1 to co respectively. The red lines indicate areas where mouse cursor switching is disabled.
