94CHAPTER 6: SWITCH MONITORING AND MAINTENANCE
c CAUTION:
■You must reboot the switch using the reboot command to validate the host program. If Flash memory space is not enough, you can delete some of the program files in Flash after completing the Boot ROM loading. (3Com recommends that you delete the host program that is no longer in use.) Then upload the host program to the switch using FTP.
■Make sure that you have saved other the configuration before rebooting.
■Do not power the switch off during the loading process.
The Boot ROM and host program loading process is now complete.
Using TFTP
Using the CLI to upgrade using TFTP is similar to using FTP. The only difference is that you use the tftp get command to download software to the switch. In this case, the switch can only be used as a TFTP client to download the software to its Flash memory from the TFTP server. Once the download is complete all remaining steps are the same.
Upgrading the If you have the 360G Fabric (3C17508), download the application software image Application Module files to the compact flash (CF) and then boot from the CF.
Program
If you have the 720G Fabric (3C17539), download the application software image files directly to the Fabric’s onboard flash.
Troubleshooting the This section describes the problems may occur during the software upgrade.
Software Upgrade
No response from the fabric serial interface
Make sure the serial interface cable is in good condition and that its attributes are set correctly.
Uploading the configuration file or host program using FTP fails
Check that the:
■Configuration is correct and that the FTP server is started.
■Flash has enough space for the target files.
■TFTP flag is selected (TFTP is not supported).
The configuration did not save during the 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 that the I/O module type is supported on the current host program.
■Check that the I/O module Boot ROM program matches the host program.
■Check that the I/O modules are well seated.
■Insert an I/O module to other slots to make sure it is not defective.
