barox Kommunikation 193.11.1. PoE ConfigurationEvery switch has a pre-defined performance capacity. This describes how much power can besupplied via the PoE ports. The crucial component here is the power supply installed in theswitch. In the above example using an RY-LGSP16-10 switch with 8 PoE+ ports, a maximumof 130 W can be supplied. This means that it is impossible to connect a 30 W terminal deviceto each of the 8 ports as this would require a total of 240 W. The integrated power unit cannotsupply this much power.This means that it is important to keep track of how much power is being supplied per port.POE appliances are divided into various categories depending on their respective consumption.Class Power available to the powered device Classification signature0 0.44 – 12.96 W 0 to 4 mA1 0.44 – 3.84 W 9 to 12 mA2 3.84 – 6.49 W 17 to 20 mA3 6.49 – 12.95 W 26 to 30 mA4 12.95 – 25.50 W (only 802.3at/Type 2)[4] 36 to 44 mAhttps://de.wikipedia.org/wiki/Power_over_EthernetReserved Power determined byOne can define how the maximum amount of power to be supplied is determined in the section“Reserved Power determined by”.- Class = corresponds to the class to which the terminal device says it belongs- Allocation = according to the value stated in the “Maximum Power (W)” column- LLDP-Med = ditto Class mode, pulls the information via LLDP (where possible)If the terminal device exceeds the predefined power limit, the port turns PoE off.
