Dpp Operation (Optional) - HighSecLabs K304 User Manual

DPP Operation (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.
In the following examples we would use the K304E for
demonstration with DPP USB cables connected in channels 1, 3 and
4 and assume that all four connected computers completed the
boot.
If the device connected to the DPP console port is not qualified –
the DPP status LED would illuminate steady red color.
In such case the device must be replaced with a qualified device.
If the device connected to the DPP console port is not standard or
undetectable – the DPP status LED would not be illuminated at all.
DPP is unusable.

Section 4 - Operation
Once the device connected to the DPP console port is qualified –
the DPP status LED should illuminate steady green.
If switch just completed power up it will be switched to channel #1
(default computer) and channel select LED #1 will be illuminated.
Once the user completed logon to computer #1 and wants to keep
the authentication device coupled to computer #1 the freeze mode
should be activated by pressing the freeze push-button. The DPP
status LED will start blinking green color. From now on the DPP
channel selection will remain on channel #1 unrelated to the KM
Switch channel selection.
If the user switches the KM Switch to channel #2, DPP channel
select #1 will remain illuminated while KVM channel select LED will
indicated channel #2.
The user may further select channel #3 and the DPP channel select
LED #1 will remain illuminated while KM Switch will indicate that
channel #3 has been selected.
