User Guidance & Precautions
Please read the following User Guidance & Precautions carefully before
using the product:
1. As product powers-up it performs a self-test procedure. In case
of self- test failure for any reason, including jammed buttons, the
product will be Inoperable. Self-test failure will be indicated by the
following abnormal LED behavior:
a. All channel-select LEDs will be turned ON and then OFF;
b. A specific, predefined LED combination will be turned ON;
c. The predefined LED combination will indicate the problem type
(jammed buttons, firmware integrity).
Try to power cycle product. If problem persists please contact your
system administrator or technical support.
2. By default, after product power-up, the active channel is #1.
3. The appropriate usage of peripherals (e.g. keyboard, mouse,
display, authentication device) is described in detail in this User
Manual's appropriate sections. Do not connect any authentication
device with an external power source to product.
4. For security reasons products do not support wireless keyboards
and mice. In any case do not connect wireless keyboard/mouse to
product.
5. For security reasons products do not support microphone/line-in
audio input. In any case do not connect a microphone to product
audio output port, including headsets.
6. Product is equipped with an always-on active anti-tampering
system. Any attempt to open product enclosure will activate the
anti-tamper system indicated by all channel-select LEDs flashing
continuously. In this case, product will be inoperable and warranty
void. If product enclosure appears disrupted or if all channel- select
LEDs flash continuously, please remove product from service
immediately and contact technical support.
7. Connecting external USB devices to product CAC port:
a. When connecting a USB device that is not qualified or rejected
for security reasons to product's CAC port, the CAC LED will
flash green and USB device will be inoperable.
b. When connecting a USB device that is undetectable for
any reason (e.g. failed device, non-standard device etc.) to
product's CAC port, the CAC LED will not illuminate at all and
device will be inoperable.
8. Do not connect product to computing devices:
a. That include telecommunication equipment;
b. That include frame grabber video cards;
c. That include special audio processing cards.
9. Product has a remote control port in the back panel labeled DCU.

User Guidance & Precautions (Con.)
10. Important! Before re-allocating computers to channels, it is
mandatory to power cycle product, keeping it powered OFF for
more than 1 minute.
11. Product log access and administrator configuration options are
described in product Administrator Guide.
12. If you are aware of any potential security vulnerability while
installing or operating product, please remove product from service
immediately and contact us in one of the ways listed in this manual.
Support for TEMPEST Devices
The Belkin Advanced Secure KVM products are compatible with
TEMPEST devices. However, we RECOMMEND against connecting the
Belkin KVM products to TEMPEST devices.
The reason is that these Belkin devices are designed with Common
Criteria Peripheral Sharing Switch (PSS) PP3.0 standards, not
TEMPEST. The TEMPEST certification mandates specific measures to
prevent electrical leakage and the PSS standards DO NOT include such
measures. Thus, connecting a switch to a TEMPEST devices could
potentially render the complete system non-TEMPEST-secure.
NOTE: Currently, there are no KVM devices available (from any
manufacturer) that are both compliant with PP3.0 and TEMPEST-
secure.

Security Features
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 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
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.
Always-on, active anti-tamper system
Active anti-tampering system prevents hardware implants and wireless
key-loggers. Any anti-tampering attempt causes isolation of all
computers and peripheral devices rendering product inoperable and
showing clear indications of tampering event to user.
Holographic security tamper-evident labels are placed on the enclosure
to provide a clear visual indication if product has been opened or
compromised.
Metal enclosure is designed to resist mechanical tampering with all
microcontrollers protected against firmware-read, modification and
rewrite.
Secure Packaging
“Tear away” packaging ensures secure delivery of the Switch as it is
routed to the end user.
