(see Figure 6-29). Each of those events belongs to an event group, which can be activated separately. The common way to log events is to use the internal log list of the KVM-0850/1650. To show the log list, click on “Event Log” on the “Maintenance” page. In the Event Log Settings you can choose how many log entries are shown on each page. - Page 72 To receive this SNMP traps, any SNMP trap listener may be used. In contrast to the internal log file on the KVM-0850/1650, the size of the NFS log file is not limited. Every log event will be appended to the end of the file so it grows continuously and you may have to delete it or move it away from time to time.

This section allows you to reset specific parts of the device. Currently this involves the video engine and the KVM-0850/1650 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. -
Page 75: Update Firmware
Updating the firmware is a three-stage process: • Firstly, the new firmware file is uploaded onto the KVM-0850/1650. In order to do that you need to select the file on your local system using the button “ Browse ” of the Upload Firmware panel. -
