Why can't I log into my Hirschmann Switch?
Web access to a Hirschmann managed switch requires the PC to have the Java Runtime Environment (JRE) installed. This is common now for a range of functions, and a copy may be found on the installation CD provided with the switch. Alternatively, the current version is available for download from java.com, where you can also verify whether the version you have installed is the latest version.
Some early model switches may experience problems with some combinations of browser and JRE, though in terms of access to some functions rather than preventing login altogether. In this event, it is best to flash the switch to a later firmware release, or Version 5 at least.
