this case, the switch can only be used as a TFTP client to download the software to its
Flash memory from the TFTP server. The remaining steps after downloading are the
same as those of remote loading using FTP.
6.3.4 Service Processor Card Program Upgrade
The S9500 series only provide a Flash memory of 16M, but the host program (including
L3PLUS) is over 15M. If no CF card is inserted, therefore, the Flash memory is
insufficient for the loaded files. You must use the update l3plus command to download
the host program (the APP file) with L3PLUS program included to the SDRAM memory
and then complete upgrade. For details about this command, refer to H3C S9500
Series Routing Switches Command Manual.
Note:
If your switch has a CF card or 32M Flash memory, you can download the host program
(the APP file) with L3PLUS program included following the common upgrade
procedure, and then both LPU and service processor card program will be upgraded.
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
z If the configuration is correct and if the FTP server is started.
z If the Flash has enough space for the target files.
z 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
z Check LPU type to see if this type is supported on the current host program.
z Check if the LPU Boot ROM program matches the host program before upgrade.
