Place the downloaded Huawei firmware file (e.g., S5700-V200R010C00SPC600.cc ) into the designated root directory of your FTP server.
Export the configuration file ( vrpcfg.zip or vrpcfg.cfg ) to your local machine using FTP, SFTP, or TFTP. Phase 2: Obtaining the Firmware and Release Notes
Ensure the output displays the new VRP version string and target release number. 2. Check Device Status display device display interface brief Use code with caution.
Set the downloaded .cc file as the startup image for the next boot cycle.
