Hello, I recently reverted to the standalone mode (mostly because I found the Nebula interface waaaay too busy). In the Nebula mode, I was able to adjust the POE modes (af, at and BT) as well as monitor the power usages. Was it some thing that was ONLY available in the Nebula mode ? Also, how can I relaunch the wizard…

ZyXEL XGS19xx IPv6
We had some strange behaviour through VLAN's. It appeared that there was on 1 VLAN an IPv6 DNS Server on an old domain controller, and in default VLAN 1 the clients sometimes got this IPv6 DNS Server. But I also saw some IPv6 gateways. When I surfed to those gateways I expected to get the firewall, but it was the…

Advice on din-rail transformer to power GS1915-8EP switch

For that reason I’m looking to hook it up to a din-rail transformer, but I can’t seem to find any that has exactly the same specs as the standard adapter: 55V - 1.3A. And I can’t find…

Normal Temperatures for XS1930-10
Hello, are these normal temperatures for a XS1930-10? The bottom of the switch is so hot (just inside the boundaries of the label), you cannot touch it; measuring 49.4C. The fan is working and the air it's exhausting isn't all that warm, nor is the rest of the chassis. The CPU sits around 5% so it's not working very hard.…
