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 identies such an attempt, all the front panel LED’s will ash 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 rmware.
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 LED’s are on and not ashing, the power up self-test has failed and
all functions are disabled. Check if the button is jammed. In this case, release the jammed button and recycle the power.
