If a port is not in a VLAN it is disabled, has always been that way and talked about many times.
A simple search reveals this post and several more.
viewtopic.php?f=17&t=1778&p=13423&hilit=+vlan+disables+port#p13423As far as disabling POE when a port is disabled I don't recall that but if it did that would be really OLD firmware and silly to be using?
The forum is better than a manual, simply search for your question and you will find posts on just about anything with the switch. If you can't find an answer simply ask and we respond fast but if you do not bother looking and I look for you and easily find it be prepared to get a little flack or even this icon
But as I said the UI is so "simple" I fail to see where a manual would be beneficial? We are a small company and feel our resources are better spent developing and supporting.
EXAMPLE OF HOW SIMPLE THE UI IS:Let's see, say I want to disable an Ethernet port, logic indicates I would do this on the Ports Tab so I click on the Ports Tab
Once there I would easily see a Column header that says "Enable" with check boxes under it for each port row so I uncheck the port I want to disable.
Done.
