The Firmware Upgrade Utility The Windows-based Firmware Upgrade Utility (FWUpgrade.exe) provides a smooth, automated process for upgrading the KVM switch’s firmware. To run the firmware, you will need to use a windows based PC with an available serial port. The Utility comes as part of a Firmware Upgrade Package that is specific for each device. New firmware upgrade packages are posted on our web site as new firmware revisions become available.
The Firmware Upgrade Utility 4. Shut down the computers on your MiniView™ Extreme installation and make sure you have set the KVM in firmware upgrade mode as instructed under section Hotkey operation → Firmware upgrade mode 5. Make sure the power is plugged into the KVM. Once the power is plugged in and the switch is set to upgrade, all of the amber lights on the KVM will flash once per second. Now you are ready to run the firmware upgrade utility.
The Firmware Upgrade Utility Starting the Upgrade To upgrade your firmware: 1. Run the downloaded Firmware Upgrade Package file - either by double-clicking the file icon, or by opening a command line and entering the full path to it. 2. The Firmware Upgrade Utility Welcome screen appears: Read and Agree to the License Agreement (enable the I Agree radio button).
The Firmware Upgrade Utility 3. Click Next to continue. The Firmware Upgrade Utility main screen appears: The Utility inspects your installation. All the devices capable of being upgraded by the package are listed in the Device List panel.
The Firmware Upgrade Utility 4. As you select a device in the list, its description appears in the Device Description panel.
The Firmware Upgrade Utility 5. After you have made your device selection(s), Click Next to perform the upgrade. If you enabled Check Firmware Version, the Utility compares the device’s firmware level with that of the upgrade files. If it finds that the device’s version is higher than the upgrade version, it brings up a dialog box informing you of the situation and gives you the option to continue or cancel.
The Firmware Upgrade Utility As the Upgrade proceeds status messages appear in the Status Messages panel, and the progress toward completion is shown on the Progress bar. After the upgrade has completed, a screen appears to inform you that the procedure was successful: Click Finish to close the Firmware Upgrade Utility.
The Firmware Upgrade Utility If the upgrade failed to complete successfully a dialog box appears asking if you want to retry. Click Yes to retry. If you click No, the Upgrade Failed screen appears: Firmware Upgrade Recovery There are basically three conditions that call for firmware upgrade recovery: • When you begin a firmware upgrade, but decide not to proceed with it. • When the Mainboard firmware upgrade fails. • When the I/O firmware upgrade fails.
