6.3.5 Troubleshooting Software Upgrade

These types of problems may occur during software upgrade:
I. No response from SRPU serial interface
Check if the serial interface cable is in good condition and if its attributes are set
correctly.
II. 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).
III. No configuration saving during LPU reboot
Before saving the configuration, you must check the operating status of the LPU. Do
not save the configuration during the LPU reboot. Otherwise, the configuration you
want to save may be lost.
IV. LPU program loading fails or you cannot register for a long period
Check LPU type to see if this type is supported on the current host program.
Check if the LPU Boot ROM program matches the host program before upgrade.
Check if LPUs are well seated.
Insert an LPU 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.
V. Insufficient Flash memory
Empty the recycle bin when the LPU starts.
Delete the unused files in the Flash.
