KVM Adapter Cable types that are not required to be upgraded. After you
have made your selection(s), click Next to perform the upgrade.
Check Firmware Version - when selected the utility compares the Main
Board firmware level with the upgrade files MAIN. If the device
versions are higher than the upgrade versions a dialog box informs you
and gives you the option to continue or cancel.
If you didn't enable Check Firmware Version, the utility installs the
upgrade files without checking whether they are a higher level, or not.
As the upgrade proceeds status messages appear in the Status
Messages panel, and the progress toward completion is shown on the
Progress bar.
To abort the upgrade procedure before it completes, click Cancel.
If you cancel before completion, a dialog box warns you that the
upgrade will not finish and shows the options to proceed or abort the
cancel operation. The Mainboard and OSD firmware may be missing or
corrupted upon rebooting the switch.
To recover from missing or corrupt firmware, see Firmware Upgrade Recovery
