Getting Started with the Graphical User Interface (GUI)

When the switch has loaded the file into its RAM, it displays the message “File transfer successfully completed”. It then writes the file to FLASH memory, which takes approximately 30 seconds after the message. Once the file has been copied to FLASH, you can enter commands that refer to it.

3.Install the new file as the preferred GUI

If you are updating both the release and the resource file, set the preferred release and restart the switch before installing the GUI as described below.

To set the new GUI resource file as the preferred resource file, use the command:

SET INSTALL=preferred GUI=filename.rsc

You can use the GUI to load the new resource file onto the switch (Management > Software > Upgrade), but you need to use the CLI to install the new file.

If you disabled the GUI to delete the old resource file, enable it again, using the command:

ENABLE GUI

Check that the new GUI resource file is valid for your device, using the command:

SHOW GUI

If it is not, or if the file was corrupted during the download, disable the

GUI, delete the file and try again.

4.Point your web browser at the switch’s IP address

Your browser may have a local copy of the old GUI file stored. If so, you need to delete these temporary files (see “Deleting Temporary Files” on page 40).

Troubleshooting

The GUI resource file has an 8-digit name, with the file extension rsc (for example, d450se01.rsc). To check which resource files are present on the switch use the command:

SHOW FILE

To see which GUI resource file the switch is currently using, and which it will use on bootup, use the command:

SHOW INSTALL

To display information about the GUI resource file that is currently installed, use the command:

SHOW GUI

In particular, this command lets you check the file’s validity. If the file is invalid or damaged, download a new file.

To display information about the switch’s HTTP server, use the commands:

SHOW HTTP SERVER

SHOW HTTP SERVER SESSION
