I have a TrendNet TPE-P521ES PoE+ Passthrough Switch which is powered by PoE+ and splits that power to two downstream PoE ports. The switch has an 18W power budget for the two ports. I wanted to use it to power two PoE devices (an AP One Mini and a VOIP phone). The AP One Mini uses about 4 watts, and the VOIP phone uses about 5W. Should be no problem, right?
Unfortunately the 521ES has a limitation - it splits the 18W power budget based on the Advertised PoE class rather than actual draw.
The AP One mini advertises itself as a “Class 3” device, meaning it can use up to 15.4W. Unfortunately, this leads the 521ES switch to think that it doesn’t have any power left. End result: the swtich will only power 1 device.
Question: Since the AP One Mini (HW2) uses less than 5W, is there any way, in software, to tell it to advertise itself as a PoE class 2 device (max 7W)?
