DPP Installation (Optional, K304E only)
Notice: The DPP functionality was not certified by Common
Criteria. Currently, Common Criteria does not offer any guidelines
for DPP peripheral support in the Peripheral Sharing Protection
Profile. The inclusion of this functionality does not affect the
Common Criteria certification applied to the rest of the product.
The following process can be performed before or after power up.
If computer and KM Switch supports user authentication device,
•
connect another USB cable CPN0444 for the DPP function. DPP
USB cable can be connected to any free USB port in the
computer.
Note: Do not connect DPP USB cable if user authentication device is
not needed. Secure KM Switch automatically detects this cable to
program DPP port selection logic accordingly.
If not all of the channels are having DPP function (some computers
not connected through DPP cable) – make sure that channel #1 is
using DPP – switch channels if needed.
When KM is powered on - once the connected device is qualified
and ready for use – the DPP status LED should illuminate green.
If connected device cannot be detected by the Secure KM Switch
then DPP status LED will not illuminate at all. Device must be fully
compliant with USB 1.1 or USB 2.0 standard.
Possible reasons:
Non standard USB device
•
Device only operating in USB 3 mode
•
Device not operating
•
