Security Features

The product is designed, manufactured and delivered in security-controlled environments. Below is a summary of the main advanced features incorporated in product:

Advanced isolation between computers and shared peripherals

The emulations of keyboard, mouse and display EDID, prevent direct contact between computers and shared peripherals. Product design achieves maximal security by keeping the video path separate with keyboard and mouse switched together, purging the keyboard buffer when switching channels. All these features contribute to strong isolation between computer interfaces, maintained even when product is powered off.

Unidirectional data flow: USB, audio and video

Unique hardware architecture components prevent unauthorized data flow, including:

Optical unidirectional data flow diodes in the USB data path that filtrate and reject unqualified USB devices;

Secure analog audio diodes that prevent audio eavesdropping with no support for microphone or any other audio-input device;

Video path is kept separate from all other traffic, enforcing unidirectional native video flow. EDID emulation is done at power up and blocks all EDID/MCCS writes. For DisplayPort video, filtration of AUX channel exists to reject unauthorized transactions.

Isolation of power domains

Complete isolation of power domains prevents signaling attacks.

Secure administrator access & log functions

The product incorporates secure administrator access and log functions to provide auditable trail for all product security events, including battery backup life for anti-tampering and log functions. Non-reprogrammable firmware prevents the ability to tamper with product logic. Configuration of front panel LEDs and CAC (if equipped) are covered in the PP4.0 Admin manual.

Always-on, active anti-tamper system

Active anti-tampering system prevents malicious insertion of hardware implant such as wireless key-logger inside product enclosure. Any anti-tampering attempt causes isolation of all computers and peripheral devices rendering product inoperable and showing clear indications of a tampering event to the user.

Holographic security tamper-evident labels are placed on the enclosure to provide a clear visual indication if product has been opened or compromised.

Selecting a Computer Using Port Selectors

Now that you have connected your console and computers to the Switch, it is ready for use. You can select which computer you wish to control by pressing the corresponding port selector on the front of the Switch. The LED number will illuminate to indicate which computer (or port) is currently selected. Keyboard and mouse inputs can only be sent to the selected computer, and video outputs can only be received from the selected computer. The Switch also prevents any data transfer between connected computers, ensuring the security of your computers.

Please note that the default port at power-up is port 1. In case of a power failure or if the power is cycled, the Switch will default to port 1.

CAC/DPP connection to the computer requires a separate USB cable connection and allows the user to specify whether there is a connected device required for that computer or not. This allows the CAC/DPP port to be connected and controlled separately to the keyboard, mouse, video, and audio.

In addition the CAC/DPP port can be programmed to allow a specific series or specific USB device(s). Contact your system administrator for details on how to program the CAC/DPP port.

Step 1 - Installation

1.1 Using the appropriate USB cable, connect one end of the cable to the computer that requires CAC, and the other end to the CAC port on the KVM Switch that corresponds to the computer. Important Note: Do not connect the USB cable if CAC functionality is not needed for that computer.
1.2 If only some of the computers use CAC functionality, make sure that computer #1 is connected to the CAC device. If needed, switch channels/computer mapping to create this configuration.
1.3 If CAC is connected it is automatically enabled.

Note: Make sure that the CAC switch is disabled (left) for all other non-connected CAC systems.

1.4 Once configured, the CAC connection will be switched only when required by the connected computer. When switching from a CAC enabled port to a non-CAC enabled port, the CAC connection can be frozen to the CAC enabled port by pressing the CAC enabled channel button 3 times in rapid succession. The CAC freeze light will illuminate. To disable CAC freeze, press the channel button three times in rapid succession to remove the freeze.

General

My computer does not boot when connected to the switch but works fine when I connect my keyboard, video, and mouse directly to my computer.

Make sure that the DP-HDMI/USB KVM Cable Kit is connected tightly between the Switch and the computer.

The Switch does not turn on.

Ensure that the AC power cord is securely connected to both the AC inlet and to the wall outlet.

Check that the power switch is in the ON position.

The Switch makes rapid clicking noises and the port LEDs flash continuously when turned on.

If the clicking noises continue, the unit may have been tampered with or experienced severe impact.

NOTE: This Switch is equipped with active anti-tamper triggers. Any attempt to open the enclosure will activate the anti-tamper triggers and render the unit inoperable. If the unit's enclosure appears disrupted or if all the port LEDs flash continuously, please call Belkin Technical Support at [phone].

Keyboard

The computer does not detect my keyboard, or my keyboard does not work when I switch computers or reboot.

Check that the keyboard you are using is connected properly to the Switch, in the USB port labeled "Keyboard."

Check that the USB cable between the Switch and the computer is completely connected.
