After additional research, I wish to revise/refine my request for assistance.
Based on the signal names near P1 on the schematic on page 67 of 90000897_K.PDF, the RJ-45 pins 4 and 5 are shorted together as POE_RJ45_4/5, and the RJ-45 pins 7 and 8 are shorted together as POE_RJ45_7/8.
With that said, somewhere in the PoE circuit there should also be POE_TX_CT and POE_RX_CT signals.
Do the Digi Connect ME 9210's VETH+ and VETH- pins correspond to the POE_TX_CT and POE_RX_CT signals, do the VETH+ and VETH- pins correspond to the POE_RJ45_4/5 and POE_RJ45_7/8 signals, or do VETH+ and VETH- pins correspond to the outputs of the bridge rectifiers, PVIN+ and PVIN- on the page 67 schematic?
I would be pleasantly surprised if the bridge rectifiers are included in the Digi Connect ME 9210 module. Given the small size of the module, maybe this is over-optimistic.
On the other hand, if the bridge rectifiers are NOT included in the Digi Connect ME 9210 module, I'm not sure how one goes about implementing a 802.11af compliant PoE design using the Digi Connect ME 9210.
