    What would be the disadvantages of running an AP-377 on a single 1 Gb/s link on E0 and POE+ (30W allocation from the switch) as apposed to a dual link? As I understand it, the AP-377 will only draw power on E0 to power the AP (even if dual connected with LACP enabled) and the additional link is to provide resiliency and capacity support if the AP has a large amount of clients connected passing a lot of data. Is this correct?

    That is correct. the second link is a 1000BASE-X SFP link, so no PoE+ delivered to that interface. I usually only see that being used when the cabling distance is to great, and a fiber network connection needs to be used. Power then gets supplied by an injector, or direct.

    If you don't have a good reason or requirement to run two cables to an AP, a single cable should be the standard (in my opinion).

    Note that the 2 Gbps of a 1 Gbps Ethernet port (duplex), is more than enough in practical cases. You need to go to specialized testing to reach the bottleneck of your Ethernet port. I see the 2 ports on the 377 more as flexibility, so you have the option to run a fiber to your AP, and PoE-power the AP over the other port.
