  • The Pronto switch
  • A computer with software that can communicate via a serial port.
  • A serial port cable to connect the switch and computer. See Serial Ports on Quanta and Pronto for more information.
  • A computer (could be the same one as above) running a TFTP server (see the Appendix on the page Up and Running on the 3290)
  • A cable to connect the Pronto switch and the TFTP server. (Or connect them to a switch or network. The They must be on the same subnet.)
  • The Indigo binary images you want to load on the switch. These must be placed in the TFTP server's TFTP directory (usually /tftpboot or /var/tftpboot).
  • An IP address for the switch on the same subnet as your TFTP server.
  • The configuration information of the switch in case the configuration has been corrupted or lost. This usually includes
    • The IP address of the switch
    • The IP address and TCP port number you will use to connect to the controller
    • The IP address of a router if the controller is not on the same subnet as the switch
    • The dathpath ID to be assigned to the switch
    • A name for the switch (optional)

Pay special attention to the placement of the single quotes ' ' and do not extend this across more than one line. (It's okay if the command is longer than one line, but don't hit the return key or use the \ key in the middle of the line.)  After entering changes, make sure you type 'saveenv' to save your changes.

...

The other files you may need to load are the Linux kernel, uImage, and the device description file, LB9A.dtb. Repeat the 'tftp -r' and md5sum commands for these files if required.

Configure and Reboot

If you are not sure if the current configuration is a problem, you can clear out the current one and place a minimal sysenv file in its place. The configuration is stored in the file /cf_card/local/sysenv. Older versions of the configuration are in /cf_card/local/cfg_history.

...

This assumes that you want to configure the system with the IP address 192.168.2.88. If it exists, you can save the existing sysenv file, in this case to a file named sysenv.old.

You can now reboot your system by typing "reboot".  Without intervention, the system should come up and run the firmware you just loaded.  You can now either use the CLI or the web interface to complete the process of configuring the switch.  To do this using the CLI, see the section Setting the System Configuration on the page Reflashing a Pronto Switch.
