Field Panel Web Server User Interface Upgrade Fails
Issue: A Field Panel Web Server User Interface upgrade fails.
Solution: A User Interface upgrade requires approximately 2.7 MB. Before performing
the upgrade, verify that Drive A has enough space. If necessary, delete the
siemensviewer.swf and fpweb.swf files from the A:\wsroot folder.

Also, FTP can be used to add and remove files from the RAM drive.
Browser Will Not Connect to the Panel
Issue: The browser window displays an error message, or the browser connects to the
Web Server, but only one panel in the navigation pane is active (the rest are grayed
out).
Solution: The browser must be configured to ignore the proxy settings for the panel
names and/or IP addresses. This can be done in most browsers via the Options dialog
box. For example:
In Internet Explorer: In the Tools menu, select Internet Options. On the
Connections tab, click the Settings button. In the Proxy Server area, select the Use
a proxy server check box and the Bypass proxy server checkbox. Click the
Advanced button. In the Exceptions area, add the panel names and/or IP
addresses being used. Separate entries with semicolons. Click OK.
In Firefox: In the Tools menu, select Options. On the Advanced tab, click the
Network tab, and then the Settings button. Select the Manual Proxy Configuration
option, and add the panel names and/or IP addresses being used. Separate
entries with commas. Click OK.
Be sure to verify with IT personnel, if necessary, before making this change.
