II. TFTP/FTP download
To use TFTP or FTP:
Run a TFTP or FTP server program on the file server or the console terminal.
Copy the upgrade file to the file server.
Correctly set the working directory on the TFTP or FTP server.
Make sure that the file server and the switch can reach each other.
III. Verifying that sufficient storage space is available
IMPORTANT:
For the switch to start up correctly, do not delete the main startup software images when you free storage space
before upgrading Boot ROM. On the Boot menu, the main startup software images are marked with an asterisk
(*).
When you upgrade software, make sure each member switch has sufficient free storage
space for the upgrade file.
Upgrade images Minimum free storage space requirements
Two times the size of the Comware upgrade package file.
If no sufficient space is available, delete unused files.
IV. Scheduling the upgrade time
You must make sure the upgrade has a minimal impact on the network services. During the
upgrade, the switch cannot provide any services.
