    6565Most Gateworks products support what is typically referred to as 'Passive PoE' as power is applied to the same pins defined in 802.3af however the intelligent signalling/detection is not present.  We do this because 802.3af DC range is only 37-60V and our customers typically want lower ranges.

     67Consider testing with the following passive PoE Injectors:

    99101== GW16090 GigE 802.af/at to GigE passive PoE Adapter
    100 The Gateworks GW16090 ([http://shop.gateworks.com/index.php?route=product/product&product_id=129 Purchase Here]) allows boards that have no 802.3af/at support to be powered by an 802.3af/at switch or boards that only support 802.3af to be powered by an 802.3at switch. The GW16090 uses the Maxim MAX5969B PoE PD Interface Controller which provides both 802.3af and 802.3at signatures to the PSE device. For more info on the controler see: http://www.maximintegrated.com/en/products/power/switching-regulators/MAX5969B.html
     102The Gateworks GW16090 (Discontinued) allows boards that have no 802.3af/at support to be powered by an 802.3af/at switch or boards that only support 802.3af to be powered by an 802.3at switch. The GW16090 uses the Maxim MAX5969B PoE PD Interface Controller which provides both 802.3af and 802.3at signatures to the PSE device. For more info on the controler see: http://www.maximintegrated.com/en/products/power/switching-regulators/MAX5969B.html

    102104The GW16090 is only intended with purely passive PoE Ethernet ports and is not meant to be compatible with ports with half rectified 802.3af or ports with true 802.3af/at and using it on those ports would be invalid and may need to unexpected results due to signature resistor conflicts.
