XMG1915-10EP: unable to adjust POE settings
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…

Can the 10Gb/SPF+ Ports Auto-Negotiate lower link speeds?
I am looking at getting the XGS1250-12 and three XMG-108's and my hope would be to use the 10Gb ports for up/downlinks. How IF my wiring distance is an issue will the port auto-negotiate down to 2.5Gb? or 1Gb?

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
I’m looking to install a GS1915 in a relatively small electrical enclosure. The standard AC-DC adapter is too bulky and with too much cable. 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…

Time Range scheduling for Switches - Problem #2
I want to set a schedule for a POE port to be active from 0631 to next day 0630, i.e. from Monday 0631 to Tuesday 0630 so that the port will shut down for just 1 min on Tuesday 0630. I can do it for all the days except for Sunday to Monday as the switch is saying Invalid Time Range. Monday 0631 to Tuesday 0630 - OK!…

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.…

Hi, I have an ES-2108-G switch. It was installed several years ago, and no one knows the password. I tried connecting with the console, but I still couldn't access it.
