4-Port Hardened Industrial Gigabit 2+ Managed DIN-Rail Switch, 4x10/100/1000 Base-TX +2x1000Base-FX SFP 6X, Network Ethernet Gigabit Not with PoE+ Switch

It shouldn't be too difficult, but sadly, there is NO English documentation provided. That wouldn't be a problem EXCEPT that the device only has 1 set of DIP switches but the Chinese documentation says they do 2 different things! See the attached image.I tried to find their website, but it also did not have any documentation (even Chinese) available for download. I guess I'll use trial and error to set the DIPs?Also, this item SAYS it has a web management interface, but the Chinese documentation does NOT include any screenshots or default IP address information, so I am starting to think that is incorrect. I'll do some scans and find out, but it's probably a mistake or a misleading claim.It PROBABLY doesn't matter - all I want is an OT switch that can be put into port isolation mode to demonstrate the microsegmentation of BlastWave.
