If you have the 720G Fabric (3C17539), download the application software image
files directly to the Fabric’s onboard flash.
Troubleshooting
Software Upgrade
These types of problems may occur during 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.
