6.6.4 Unit Reset
Figure 6-35 Unit Reset
This section allows you to reset specific parts of the device. This involves the both keyboard and
mouse, the video engine and the DKVM-IP8 itself. Resetting the card itself is mainly needed
to activate a newly updated firmware. It will close all current connections to the administration
console and to the Remote Console.
The whole process will take about half a minute. Resetting sub devices (e.g. video engine)
will take some seconds only and does not result in closing connections. To reset a certain
DKVM-IP8 functionality click on the button Reset as displayed in Figure 6-35.
Note: Only the super user is allowed to reset the DKVM-IP8.
