9. On the Choose Firmware File window, double-click on the new firmware file to open it. The Choose Firmware File window closes, and the path to the selected firmware file is displayed in the “Select a firmware file” field on the firmware file selection screen.

10. Click the Upload button. A status bar, which shows the progress of the upload, appears in the Firmware Loader window. The firmware upload to the switcher may take several minutes. Once the status bar has progressed fully from left to right, the firmware loader resets the switcher.

In addition, messages appear on the firmware loader window, indicating when the unit is uploading the firmware, then resetting itself.

CDo not interrupt the firmware upload before it is 100% complete. Interrupting the upload corrupts the firmware and the switcher will not operate properly afterwards.
