The Tp-link panel ap (TL-AP300I-POE) and the ceiling-top AP (Tl-ap300c-poe, Tl-ap450c-poe) support IEEE 802.3af/at, a standard Poe-supported device, while supporting Poe Mode A ( Power transmission and data transmission common twisted pair) and PoE mode B (power transmission and data transmission using separate twisted pair) of two power supply modes.
PoE Mode A has 1, 2, 3, 6 line pairs for power transmission and data transmission; PoE Mode B Power Transmission uses 4, 5, 7, 8 line pairs, data transmission using 1, 2, 3, 6 line pairs.
Power transmission and data transmission using the same twisted pair
Power transmission and data transmission using different twisted pair
Note: The POE switch currently supports only Poe mode A, but the AP product supports 2 modes of power supply and is perfectly compatible with all kinds of Poe power supply devices.
