PoE pin assignment in switches
What is PoE pin assignment (+/-) in PoE switches like a RG-ES218GC-P, RG-ES106D-P, RG-ES110D-P and other models?Regarding the PoE pin assignment for our PoE switches, such as the RG-ES218GC-P, RG-ES106D-P, and RG-ES110D-P, the standard PoE pin assignment is as follows:
[*]Pair 1 (pins 3 and 6): Used for data transmission (Ethernet).
[*]Pair 2 (pins 1 and 2): Used for power transmission (DC power).

Thanks! There is just one pair to transmit DC power? So what about other 2 pairs? And where are positive and negative pins?

Thank you for your follow-up question. In PoE (Power over Ethernet) implementations, there is typically one pair (Pair 2) used for power transmission. The other two pairs (Pair 1 and Pair 3) are primarily used for data transmission (Ethernet traffic). To clarify, in the context of PoE:
[*]Pair 1 (pins 3 and 6) is used for data transmission.
[*]Pair 2 (pins 1 and 2) is used for power transmission.
As for the polarity of the power transmission, the positive and negative pins can be represented as follows:
[*]Positive: Usually, this is transmitted over pin 1.
[*]Negative: Typically, this is transmitted over pin 2.
This polarity ensures that the device receiving power can identify the correct voltage orientation.
I hope this clarifies your question. If you have any further inquiries or need more details, please don't hesitate to ask. We're here to help.
