Do the lighting node stripes have to be connected and linked in a closed cycle?

Hi,

 

ok so long story shirt I know absolutely nothing about building in hardware. Already erased some issues but the problem was that I had no free slot for the lighting node pro on my mainboard. I didnt build this PC myself so I found another lighting node in between a bunch of cables, one slot was already occupied the other one wasnt so I plugged the RGB stripes in.

 

I connected then all in a row and now the end obviously isnt plugged in and is dangling around a bit. Is that bad or normal? Or do I have to plug it in somewhere so that the cycle is fully closed?

 

Thanks in advance

[sorry for the long text for such a minor issue]

That's normal and fine. The last strip in the chain will have a dangling connector.
