I try to upgrade the system to 1.4.0.88 and it fails with error
Status: Copy failed Error Message: Copy: SW code file is over sized
I am using HTTP for the upgrade. Any suggestions?
Switch to TFTP (you will need to install and run a TFTP server probably on your workstation)
Select Boot Install file sx300_boot-13506.rfb
After rebooting it should work. You can also upgrade to 1.4.1.03
