I am currently the IT chair for my fraternity house. Recently our Adtran NetVanta 1234P went out. Luckily it has a lifetime warranty so I got a new one. I hooked it up exactly how it had been hooked up before. We have the Switch hooked up to a SonicWall NSA 250M. The new switch is not receiving internet from the SonicWall, however a small 4 port netgear that I also have hooked up to the SonicWall still works. I was wondering if there was some sort of initial configuration I have to do so the SonicWall will recognize the new switch. Also someone mentioned to me that PoE switches need to be looped. I have the ethernet looped backed to the SonicWall, so two ports need to be hooked from the SonicWall to the switch. Is that correct?
