switch-chip in hAP ac^2

[DmitryAVET]

Hello Mikrotik!

I have question about block diagram for hAP ac^2

Here you write, that hAP use AR8327 integrated in IPQ-4018

If we looking on official datasheet:
https://www.qualcomm.com/media/documents/files/ipq40x8-ipq40x9-product-brief.pdf
ipq-4018 really have integrated switch engine

On the otherside in qualcomm datasheet we see QFE8075 5/2 ports GE PHY (5 eth + 2 lanes each 1 Gbps?)

So if we open hAP ac^2, we can see QCA8075 between IPQ-4018 and physical inerfaces.

Can you explain more detailed, it is error or what?

the device identifies itself as Atheros-8327.

the QFE8075/2 is just a PHY and it is not part of the SOC. the block diagram you pasted from the qualcomm datasheet also shows the QFE outside of the SOC as a possible add-on accessory. and it is also present on the photo of the hAP ac2, right on the bottom.
