I have this exact Huawei as my failover internet connection, works perfectly except doesn't do PoE so I need to have a stupid wall-wart for it.
You can buy PoE splitters that will take ethernet in and give you ethernet + some power supply out. Looks like you need 12V/2A and a cursory search throws up a few options.
