By default, NP-SM4 switch does not feed the ports P0, P1, P2. There is a need to install jumpers on a board of a switch to feed one or several ports. Two jumpers are responsible for each port. A location of jumpers is shown at the picture 7. - Page 10 Installing of a jumper J6 disables a function of auto determination, which is used by PSE devices to determine a presence of PoE consumers (PD devices). Thus PSE devices will feed NP-SM4, which has a jumper J6 installed. J6 jumper is not included into a shipping kit.
