If you have the 720G Fabric (3C17539), download the application software image files directly to the Fabric’s onboard flash.

Troubleshooting These types of problems may occur during software upgrade:

Software Upgrade

No response from fabric serial interface

Check if the serial interface cable is in good condition and if its attributes are set correctly.

Uploading configuration file or host program using FTP fails

Please check

If the configuration is correct and if the FTP server is started.

If the Flash has enough space for the target files.

If the TFTP flag is selected (TFTP is not supported).

No configuration saving during I/O module reboot

Before saving the configuration, you must check the operating status of the I/O module. Do not save the configuration during the I/O module reboot. Otherwise, the configuration you want to save may be lost.

I/O module program loading fails or you cannot register for a long period

Check I/O module type to see if this type is supported on the current host program.

Check if the I/O module Boot ROM program matches the host program before upgrade.

Check if I/O modules are well seated.

Insert an I/O module to different slots to check if it is OK.

Check if the host program exists and if the current host program is the running one.

Insufficient Flash memory

Empty the recycle bin when the I/O module starts.

Delete the unused files in the Flash.

Password Loss

If the Super password or Boot ROM password of the Switch is lost, please contact

 

your local support representative.
