WHAT’S IN THE BOX?

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 LEDs 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.

SELF-TEST
A self-test is performed each times the KM is powered on as part of its boot- up sequence. If the KM starts up correctly and is functional, the self-test has passed. However, if all Front Panel LEDs 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.
