Here is Florian Bomer’s recommendation and I think probably best for your use case. My use case is different where I require equipment and ethernet connection simultaneously in my home office. In my case my switch also provides POE to BomeBox as it is a POE enables switch.
For POE out, you should be able to hook that to any ethernet device as per the POE spec, it will only activate if the receiving device uses it. It is safe to use POE out on the BomeBox to Mac or CQ because neither of these devices need POE so the power negotiation will not happen on that connector and POE there will not be activated.
