Secure Large KVM Switches User Manual
DPP Operation
The product is equipped with DPP port enabling connectivity to
external USB-devices such as smartcard reader.
Summary of rules that apply to DPP switching
:
It is assumed that a "connected channel" is when:
1.
Product is powered ON
2.
The USB device connected to product console is qualified
and ready for use, as indicated by the DPP status LED
illuminating steady green.
3.
The channel DPP port on product is connected via USB cable
to a USB port on computer.
When the USB device connected to the DPP console port is
qualified, the DPP status LED on the front panel would
illuminate steady green.
o
When connecting a USB device that is rejected for
security reasons to the product's DPP port, the DPP
LED will illuminate steady red and USB device will be
inoperable. In such case the USB device must be
replaced with a qualified device, either USB smart
card or CAC reader.
Since channel #1 is the default active channel after power up
and in case only some of the channels operate with a USB
device, it is recommended to make sure computer #1 is
connected to USB device.
Once the user switches channels, for example to channel #3,
DPP functionality will move to computer #3 and be indicated
by channel #3 DPP LED turning steady green.
In case user switches to a channel that is not connected to a
USB device, the DPP function will remain with the last
channel that had DPP connection.
