Powering 2 devices from hAP ac3 PoE-out port

Tue Mar 30, 2021 4:41 am

Soon I'm going to have a hAP ac3 powered by 24v PoE in. Its PoE-out port could power both a SXT LTE6 and a mANTbox 12s. Together, those devices would take 18w maximum power which is 0.75A, more than the 0.5A supported by the 0.5A maximum. Is this safe? I had a similar question about a cAP ac and a similar setup, but this is different.

I wouldn't do it, there's real chance that either PoE out port gets damaged or that both PoE-powered devices will not be stable. If you really want daisy-chain both PoE-in devices and run them off single PoE cable, use RBGSP injector which has 2A limit.

I tried doing something smilar with my hap ac3, i tried to power QRT 2 and hap ac lite at the same time.
They worked. Kinda...
As long as they were idle everything was fine, but the moment there was some traffic (thus more power usage) they would randomly freeze/restart.

In summary, a big no-no. As suggested, it's better to get a nice PoE injector/s which is/are rated for the max current (sums).
