Does POE injector needs ventilation?

[Vijay_network]

I have my access point powered by a POE injector. I am planning to install into my NetworkBox which is in my closet and has no ventilation. Should this be ok or should I take it outside and give proper ventilation for it?

PoE Injectors use very little current and rarely do they get hot.

Maybe if you have something really really really far away, like 150ft+ it may get warm, but if its a good quality injector like a ubiquiti, or a good PoE Switch, they can do fine inside a closet.
