1. Depending on the hardware versions the remote reset would be located in front of the device where the Ethernet ports are or on the left side when facing the Ethernet ports, and the passive LED indicator is on top.

2. Here is a FAQ showing the various power specs for the SMB devices: https://www.tp-link.com/no/support/faq/906/ if the adapter is within spec it should work.

3. Non-RJ45 connectors?

4. Typically the power is interrupted similar to holding the reset on the device itself.

Many thanks for the reply.

The way the Poe adapter was mounted, the only side I could not see, had the reset hole.

All the browsing I did showed it to the left of the Ethernet connections.

Apologies for not looking further and not seeing that.

3. Non-RJ45 connectors?

Yes, in other words reliable screw terminals (clamp type)

I have already removed 3 Plug/Socket connections by using ScotchLok  connectors that have protective gel

that gets released after crimping.

I don't know if there are better quality  RJ45 crimping plugs, but one moment I have all 8 connections

and the next I don't. Also I am worried about long term salt air affecting them.
