I have 2 300 foot runs. Cat 5E. The switch attached to is a cisco POE fully managed Switch. The run in question currently supports 2 time clocks. I need to lay out solid, meshed WiFi. The units supplied by the coporate home are Ubiquiti AC Pros. They each require POE. To that end I have a inexpensive 8 port POE 802.3AF managed switch due in on Wednesday. The idea is simple. Take the run and place into switch thereby joining the Layer 2 network. Then we will have perfectly recondition the electronic signal as is consistent with Switching technology. The Switch being a Managed POE will also supply my further run out Access points with POE.
This is completely compliant with The OSI model in theory. The cheap switches, well, ive used them many times at other locations in other applications. Sure, the best thing would have been a fiber run to my distribution cabinet,, but no such luck.
Has anyone applied a POE switch at or near the 100 meter limit. For all practical purposes this will work. Further, in teory a layer 2network can be grown to any conceivable size. Limited only by the switching fabric and IP address.
