1 PRODUCT OVERVIEW
Cybex™ SC switches are field-proven, secure, KVM and KM switching solutions with special support for
government agencies. This switching system allows users to switch safely between computers operating
at different classification levels from a single set of peripherals, providing continuous access to critical
data. With multiple security features, the secure design prevents the transfer of data between the
connected computers, ensuring data security is not compromised.
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 have been tampered with or if all the port LEDs flash
continuously, please contact Technical Support.

1.1 Features and Benefits
The SC switching system offers the following options, depending on the model:
•Support for HDMI, DVI-I, VGAand/or DisplayPort video
•Support for Common Access Card (CAC), USB biometric device and USB authentication token
•Certification to Evaluation Assurance Level (EAL) 4+
•Support for USB and PS/2 keyboard and mouse
NOTE: Supports most keyboards and mice. For more information, contact Technical Support.
The SC switching system is also designed to provide additional layers of security, preventing unintended
data leaks between computers and providing additional USB port protection.
FEATURE DESCRIPTION
Complete
network
segmentation
Data flow is controlled and insulated from peripheral devices using optical data diodes. EDID emulators and
internal firewalls protect shared displays and prevent external memory leaks.
Protection from
shared
resources
The switches are designed to securely operate, even when peripheraldevices are vulnerable to signaling attacks.
They do not allow computer access to any shared resource and do not share controllable power sources.
Non-
reprogrammable
firmware
Custom firmware is not reprogrammable preventing the ability to remotely attack switch controllers.
Audio
protection Microphone switching is not supported to prevent data leaks through audio ports.
CONSOLE USB
port protection
CONSOLE USB ports protect from the use of unsafe USBstorage devices. Unqualified devices are rejected when
connected through the switch even though keyboard and mouse data is passed through.

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 DPPfeature allows secure use of authentication devices such as a CAC or smartcard reader. See the
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 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 USBdevice is connected to the switch and ready for
use. If the USB device is not qualified or is rejected from the switch's DPPport, the DPPstatus LED flashes
and the USB device is inoperable. If the USB device is not detected by the port, the DPPstatus LED does
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 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.
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 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.
