Software Upgrade Procedure

The application software is field upgradable. The upgrade procedure and the required equipment is described in the following section.

Note that once the system is up, it is controlled by an executing application image residing in the flash memory. No software upgrade is possible during this mode. The upgrade can only be done when the system is resetting. To initiate this sequence, the user must set the "boot mode" configuration parameter to "Boot from Net" during normal operation, and then perform a "reset". When the Boot-from-NET option is set, Bootstrap can start the system with an image residing on a TFTP server on the network. Be sure that the TFTP server residing on the network is accessible by the WGSW-800.

(Note: It is Highly recommended, though not necessary, to use a RS-232 serial port connection to the switch during the software upgrading procedure. When using a Telnet Session or web interface alone, your connection to the switch will not be available until the switch has entered forwarding mode. This takes approximately three minutes. Once completed, the software version should be verified in the Software Download page. If the older version of the software has not been replaced, the unit was unable to reach the new software and booted from the old "flash" version)

The upgrade procedure is as follow:

  1. Go to System Manager/General/Software Download (in the Web or Console Interface).
  2. Set "Boot from Net" option during the normal operation.
  3. Verify information such as the IP address for the TFTP Server, Gateway IP address, and the file name and its path of the new image, then perform "Submit" in the Web or "Ctrl-W" in the console interface. The bootstrap process allows for those items to be changed via the console.
  4. Restart the system with "Boot from Net" set.
  5. Bootstrap will retrieve the new image then pass control to it.
  6. The system executes the new image.
  7. (Note that the previous image in the flash will not be replaced by the new image using this option. The image in the flash will be over-written if "Boot from Net and Saved" option is selected.)
  8. If you decide to upgrade to the new image, go to Software Download again. Set "Boot from Net & Save" option, and perform "Submit" in the Web or "Ctrl-W" in the console interface.
  9. Restart the system with "Boot from Net & Save" set.
  10. The new image should over-write the old image in the Flash memory. Verify it by going to the Software Download screen and checking the Software Release information.

Note: It is recommended to perform the upgrade procedure from the Console Interface via RS-232 serial port.
