Hello, I want to buy this switch (Mikrotik CSS610-8G-2S+IN) and I want to use some access points (MikroTik cAP ap, RBcAPGi-5acD2nD). I don’t know if the switch can charge the access points through PoE with energy.

Also, can I get a cable from Access Point 1 to Access Point 2 with Ethernet and power for that model of AP?
Thank you!

And if that switch doesn’t do what I need, can this model? MikroTik CRS112-8P-4SIN
Or help me by telling which switch I need to buy with at least 8 PoE ports. Thank you!

You need to do your homework a bit better.

1- determine how many devices you need which should be powered
2- determine for each of these devices the TYPE of PoE (it could be passive !) and the required power budget
3- sum it up to determine how much your switch should be able to provide
4- as for daisy-chaining multiple APs, it can be done but be aware of the power budget the first one is able to give to the next one, and the PoE type the 2nd one needs and what the first one can give. More then 2 is rarely possible.

  1. the CSS610 has no Poe out, so not suitable, but see below.
  2. the two Cap AC can be daisy chained, each one will be around 12W, so the source needs to be 802.3at i.e. max around 30 W
  3. the CRS112 seems suitable, it can deliver on a single Port active PoE 802.3at 450 mA, at 48v they are not enough, you will need to power It at the max voltage, 57v and It will barely be enough, 25,65 W (it needs to be checked the voltage drop that you will have that depends on the type and length of the cables).
    Be advised that this switch is also limited to 1.4 A total output, so it has to be seen what power you need on the other 7 ports.
    In your setup you cannot use the built-in Power supply and you need anyway and external Power supply, and the standard Mikrotik ones are not suitable, being at only 48v.
    If you don’t have an actual need for the AP’s to be powered through the switch the CSS610 is faster and cheaper.
    And a “plain” PoE Power supply will be not so “tight” with amount of power delivered.

The CSS610-8P-2S+IN https://mikrotik.com/product/css610_8p_2s_in would work wonderfully for you. Just remember it is the 8P not 8G variant.

And It has 625 mA on the PoE out, definitely no issue for the two daisy chained AP’s!

Wouldn’t be better to get newer cAP AX then older cAP AC?

II forgot to mention that I will use a total of 5 access points that I want to power through PoE, and from the switch I also need about 4-5 PoE slots for other devices. It would be very helpful if you could recommend a switch that meets my needs. The other devices do not need to be powered by PoE.

The CSS610-8P-2S+IN gabacho4 suggested has a total 140 W PoE output, it is more or less the max you can expect to find, it will have no issue with 8 PoE devices below 15 W each or a couple ports at 30 W and 4-5 at 15W.
