NOTE:

1. Attention should be paid to the following issues when loading images through TFTP servers :
   • Ensure that you are properly configured as a TFTP server;
   • Ensure that Switch routes to TFTP servers are accessible. If there is no router for routing communication between subnetworks, switches and TFTP servers must be in the same network;
   • Make sure that the configuration files you want to download are in the correct directory on the TFTP server;
   • Download operation to ensure that the file’s permissions are set correctly.

2. After successfully entering the system, it is still necessary to download the upgrade package from the TFTP server to the switch system folder according to the routine process. And specify the upgrade package as the next load project for the system to start. For more information, please refer to the S5850-24S2Q Switch FSOS Software Upgrade Guide.
