For example, I will configure CAPsMAN v2 on MikroTik PowerBox Pro with MikroTik cAP ac access points (RBcAPGi-5acD2nD), instead of PowerBox Pro you can use, for example, MikroTik hEX PoE (RB960PGS), they have 4 POE Out ports, you can connect 2 access points to one POE port, the recommended cable length is up to 80 m, so POE can power 8 access points, but you need a more powerful power supply than the one included, for example, I remember in the PowerBox Pro manual it says that at 24V 1A on the POE port, at 48V 0.5A, so you need a 24V 6A or 8A power supply. If there is not enough current for the access points, then they will reboot when, for example, the CPU is more loaded. Thanks to CAPsMAN, by changing the configuration of wireless interfaces on the main device, such as password, frequencies, etc., they are changed on all access points automatically.

I will give an example of how I connected Lifepo4 batteries to the EPS30-4815AF power supply (it contains two 15A power modules).
For example, the first battery was US2000C Pylontech 50Ah 48V.

I ordered GPON ONT Huawei HS8346X6-C from China, the firmware has English and Chinese languages. There are only Chinese inscriptions on the indicators and ports, well, no one really pays attention to them. PON, as usual, blinks red when there is no signal, blinks green when registering, lights up green when everything is ok.
I will show a photo when the optics are not connected and when the ONT is registered.
