I have a HPE 1920S 48 port switch that is linked to a netgear unmanaged switch through a single ethernet cable which has 10 cameras connected through it and then on to a DVR through the HP switch. For some reason the port is dropping from 1000M to 100M and all the cameras drop out and everything stops working. If I reset either switch the port comes back up at 1000M and everythign works untill it happens again.
I have no idea why and cannot seem to find an answer so I'm asking here if someone can point me in the right direction as to why this is happening
How do I stop port 48 on the HP switch from doing this?
