SECURITY FEATURES

ANTI-TAMPER SWITCHES
Each model is equipped with internal Anti-Tamper switches, which sense attempts to open the device enclosure. Once the system identifies such an attempt, all the front panel LED’s will flash rapidly and the unit will become useless by shutting off connection with all attached PCs and peripherals disabling any functionality.

TAMPER-EVIDENT SEAL
The enclosure of the unit is protected with a tamper-evident seal to provide a visual evidence if the unit has been opened.

PROTECTED FIRMWARE
The controller of the unit has a special protection feature that prevents reprogramming or reading the firmware.

HIGH ISOLATION ON USB CHANNELS
Opto-isolators are used in the unit to keep USB data paths electrically isolated from each other, providing high isolation and preventing data leakage between ports.

SECURE EDID EMULATION
The unit prevents unwanted and unsecure data to be transmitted through the DDC lines by means of secure EDID learning and emulation.

SELF-TEST
A self-test is performed each times the KVM is powered on as part of its boot- up sequence. If the KVM starts up correctly and is functional, the self-test has passed. However, if all Front Panel LED’s are on and not flashing, the power up self-test has failed and all functions are disabled. Check if any of the front panel port selection buttons are jammed. In this case, release the jammed button and recycle the power.

INSTALLATION

Power up the PC and the Secure KVM Switch.
Download the Administration and Security Management Tool to your PC from this link:|https://www.blackbox.com/NIAP3/documentation
Run the Administration and Security Management Tool executable file.

Initiate the session using the following steps in the Administration and Security Management Tool:

Type “alt alt c n f g” on your keyboard
The mouse connected to the Secure KVM Switch will stop functioning and you will be prompted to “Enter credential id”
Login in as the administrator by entering the default username “admin”, and pressing Enter.
Enter the default password “1 2 3 4 5” and press Enter.
Seven options will appear in a numerical menu: select option 6 and press Enter.

CAC (COMMON ACCESS CARD, SMART CARD READER) INSTALLATION

INSTALLATION

The following steps are intended for the system administrator or IT manager only. If you have the optional CAC ports there will be 2 ports on a 2 host ports Secure KVM Switch and 4 ports on a 4 host ports Secure KVM Switch. CAC connection to the computer requires a USB cable connection separate from the keyboard and mouse. This allows the CAC to be connected independently from the keyboard and mouse. It also allows the user to select whether CAC for a certain computer is supported or not.

Ensure that power is turned off or disconnected from the unit and the computer.
Use a USB cable (Type-A to Type-B) to connect a USB port on a computer to its respective CAC USB ports on the Secure KVM Switch. Do not connect the USB cable if CAC functionality is not needed for that computer.
Connect a CAC (smart card reader) to the CAC port in the user console interface.
Power on the Secure KVM Switch by connecting a 12VDC power supply to the power connector, and then turn on all the computers.
To disable CAC for any channel (all CAC ports are enabled as default), use the front panel buttons to switch the Secure KVM Switch to the channel whose CAC mode you wish to change. Once the channel is selected, the button LED for this specific channel should be on (CAC port enabled). Press and hold the button for 3 seconds until the button LED turns off. The CAC port is now disabled for this channel. To enable CAC for any channel, use the front panel buttons to switch the Secure KVM Switch to the channel whose CAC mode you wish to change. Once the channel is selected, the button LED for this specific channel should be off (CAC port disabled). Press and hold the button for 3 seconds until the button LED turns on. The CAC port is now enabled for this channel. An active session on a computer is terminated upon removal of the CAC device.
Note : The open session will be immediately terminated upon the removal of the registered CAC device.

CAC PORT CONFIGURATION

The following steps are intended for the system administrator and operators (users).
Note : Only one computer connected to port 1 is required for this operation.

CAC port Configuration is an optional feature, allowing registration of any USB peripheral to operate with the Secure KVM Switch. Only one peripheral can be registered and only the registered peripheral will operate with the Secure KVM Switch. By default, when no peripheral is registered, the Secure KVM Switch will operate with any Smart Card Reader.

Configure the CAC Port via User Menu Options

Open the Administration and Security Management Program.
Using the keyboard, press the Alt key twice and type “cnfg”.
At this stage the mouse connected to the Secure KVM Switch will stop functioning.
Enter the default username “user” and press Enter.

Select option 2 from the menu on your screen and press Enter.
Connect the peripheral device to be registered to the CAC USB port in the console side of the Secure KVM Switch and wait until the Secure KVM Switch is reading the new peripheral information.
The Secure KVM Switch will list the information of the connected peripheral on the screen and buzz 3 times when registration is completed

AUDITING: Dumping the Event Log via User Menu Options

The following steps are intended for the system administrator.
