WGSW-800 8-Port Gigabit Ethernet SwitchChapter 5 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:
Note: It is recommended to perform the upgrade procedure from the Console Interface via RS-232 serial port.
