RouterOS General

i have a strange problem with 3 of my mikrotik , when i power on the rb without connecting the POE Injector Splitter to the switch is ok, as soon as i connect the POE Injector Splitter to the switch the cable from “”“POE Injector Splitter to RB”“” warms up. like is melting… need help on this have tried with different POE Injector Splitter and lan cable , same results. it warms up as soon as i connect to a switch hub or router .

its perfectly possible a warm cable but not too hot to be melting.

be sure of using quality utp cable because cheap utp cable uses less diameter conductors and even not cooper conductors

be sure cable is not on short circuit
