I have not yet deployed an IAP-275, but we are installing one for a customer. In the installation guide, it states that "The WAN port supports 802.3at Power over Ethernet (PoE), accepting 48 VDC (nominal) as a standard defined Powered Device (PD) from a Power Sourcing Equipment (PSE) such as a PoE midspan injector." Does this mean that ONLY the WAN port will accept POE+ and, therefore, I should plug the ethernet cable from my switch into the WAN port instead of the LAN port?
