Do you also have to set up Hirschmann swtiches for the first time ?!? Well yes, they dont come with default IP address and if you, like me, dont have a serial cable to configure them, yes you are also F*** !!!
Well good news, you could use Hirschmann Discovery tool, HiDiscovery to set up the IP and configure the settings. It's very well explained in this video ...
OBS: you have to set a static IP on your ethernet adapter, if not the HiDiscovery will go NUTS !!!
