What can I do if the available storage space is insufficient when I want to upgrade an S series switch
If the available storage space is insufficient when you want to upgrade an S series switch (except the S1700), perform the following operations: Run the dir command to check the remaining storage space. If the remaining storage space is insufficient for saving new system software, run the delete /unreserved XXX command in the user view to delete unnecessary files. All files displayed in the output of the dir command can be deleted as long as the deletion does not affect running of the switch. You can delete the system software package of the earlier version because system software packages generally occupy relatively large spaces. Do not restart the switch after deleting the package because it cannot start without a system software package. Restart the switch after the new system software package is uploaded and specified as the package for the next startup.
