I have got TP-Link TL-SG2210P. PoE switch with the specifications in the link below :
Permenantly 3 PoE Hikvision security cameras connected to it ,,,,,but once I connected 3 or 4 other ethernet cables for desktop computers the whole switch gets shut down ,,,,sometime working fine allof the sudden gets switched off !!!!
Can you please advise what should I do to troubelshoot the problem ?
