POE pinouts

Hi,

Could someone please advise the Bullet2 RJ45 pinouts for POE?

I assume the green and orange pairs are data, and blue and brown power?

Thanks, Grant.

Re: POE pinouts

Correct.

Pins 1 & 2 (wht/org & org/wht for 568B standard or wht/grn & grn/wht for 568A standard are one data pair.

Pins 3 & 6 (wht/grn & grn/wht for 568B standard or wht/org & org/wht for 568A standard are one data pair.

Pins 4 & 5 (blu/wht & wht/blu) are the positive power pairs.

Pins 7 & 8 (wht/brn & brn/wht) are the negative power pairs.

The power pairs are floating, i.e. the negative pair is not at earth ground potential

Re: POE pinouts

All I did was describe the pinouts of the PoE.

Now from there, it is up to you if you want to use a straight or crossover cable. Either one works, but there is no need to use a crossover cable. I'd say that 99.999% of the people use a standard straight through cable from the PoE injector's PoE port to the radio.

If you use a straight through cable, make sure you also use a straight through cable from the PoE injector's LAN port to the rest of your network.

Re: POE pinouts

It means all pins are used. I got one wire(orange) broken internally. Is there any way to use insted if any one wire is not used?

 

Thnx

Re: POE pinouts

All four wires (wht/org, org/wht, wht/grn, and grn/wht) are necessary for data if modular jacks are wired for 568A or 568B standard.

If push comes to shove and the break is unaccessable for splicing and cable less than 100 feet, you could redo jacks such that the org pair is used for power.
