remove the network connection of the NIU (port 4) end check if it stays stable. NIU is known to restart under high network traffic load (especially ARP storms and broadcasts)

My PBX is far away from the my City and if i remove the network connection of the NIU (PORT 4) i can`t have the acces from the system .
You can give me some addvice what i need to do ?

 

[b17liviu]

In the PORT 2-3 from NIU 2 board is connecting whit AAU 2 board Port 2-3
Remove the port 2-3 of the NIU2 ?

 

[whosrdaddy]

no only disconnect network port, ports 1-3 are V24 and should not be affected.

Hello,
you attempted to update the firmware niu?

 

[b17liviu]

I don't want to update .
I have removed the network connection from the NIU2 port 4 and I did't have any alarms in this time (24 h).
Can you tell me what reason could be?

 

[whosrdaddy]

see my first reply, the NIU board is very sensitive to high network traffic loads. usually we resolev this issue by placing a cheap router between the NIU and the rest of netwoek, assuring that only the traffic that is meant for the NIU (so broadcasts are blocked) will get through.
