Chapter 35 Firmware and Configuration File Maintenance 35.5.7 Uploading Via Console Port FTP or TFTP are the preferred methods for uploading firmware to your P-792H v2. However, in the event of your network being down, uploading files is only possible with a direct connection to your P-792H v2 via the console port. Uploading files via the console port under normal conditions is not recommended since FTP or TFTP is faster. Any serial communications program should work fine; however, you must use the Xmodem protocol to perform the download/upload. 35.5.8 Uploading Firmware File Via Console Port 1 Select 1 from Menu 24.7 - System Maintenance - Upload Firmware to display Menu 24.7.1 - System Maintenance - Upload System Firmware, and then follow the instructions as shown in the following screen.
