Usage guidelines
You can upgrade the PSE firmware in service in either of the following modes:
• Refresh mode—Updates the PSE firmware without deleting it. You can use the refresh mode
in most cases.
• Full mode—Deletes the current PSE firmware and reloads a new one. Use the full mode if the
PSE firmware is damaged and you cannot execute any PoE commands.
