The PCIe-NX156U3's specs say nothing about PoE either way, so I can't say whether it supports it.
In short, pick the PCIe-NX154PoE if you need several Ethernet ports or PoE-powered devices. Pick the PCIe-NX156U3 if you need many USB ports.
You can check the details in each product's datasheet: PCIe-NX154PoE and PCIe-NX156U3.
