Am a bit confused by these switches that do PoE

 

For example the TL-SF1009P

 

Installation guide says can support up to 65w.. Now I have a router and an AP point both PoE with combined power of 48w.

 

What I do not understand is the router needs 48v ant 0.5A and the AP point 24v at 1A

 

So can this switch do both and if so how does it know the voltages needed?

 

Thanks

You have to be careful when using the PoE devices - they have to support the same PoE standard.

Here are the voltage for standard PoE:

IEEE 802.3af 37-57 V 100 m
IEEE 802.3at 42.5-57 V 100 m

TL-SF1009P supports 802.3af/at PoE+ standard.

There's also a passive PoE which could be 24V, 48V and 54Va fixed output voltage is provided and there is no negotiation performed.

Some of the APs support a passive PoE which is a different standard.

  @Bogart99 My all sounds complicated think I will stick with each device using its own PoE psu.

That would be best in your case. The main rule when using PoE is that devices should support the same/compatible PoE standard (voltage) - otherwise you can cause a damage.
