- Tutorial
There are situations when something needs to be done quickly, there is no time to buy, and there are all small things on hand. It is from this situation that the self-made PoE Injector is obtained. (Purchase costs around 300r).
For the manufacture we need:
Next, you need to read what PoE is, and what options are there, as a result, you can understand what suits us: the 802.3af standard, the PoE-B or Passive PoE option (they are identical in the connection scheme, but Passive PoE does not support the protocol part).
And then it’s just that we all switch, at the output we have:
Well, if you have a patch panel, and a powerful power source, then you can make a similar design, but for 16 or more customers (of course it’s not good to power everyone from one source, but this is another problem).
For the manufacture we need:
- 12V power connector (mom or dad) 2.1 * 5.5 * 10mm with terminal block, about 30p
- Wall socket RJ45 double, approximately 150 rub
