sensor gateway offline

Hello,

some time ago, our company bought a SensorGateway with the purpose to test the device's features in relation to environmental monitoring using Nagios. We were not able to connect to the configuration web interface then. I was temporarilyassigned other duties, so 3 years later I'm back on the job and trying to get the thing to work as intended.



I still cannot connect to it on factory-set IP 192.168.11.160, whether it is powered through PoE or an AC adapter; when I reset it using the reset button, I sometime get ONE ping seemingly reaching the device (with outrageous time reading though).



Is this a known problem, is there a solution ?



Thanks in advance for your attention.

Here is a link that might help

https://www.serverscheck.com/sensors/nagios.asp

Thanks, it might help iff I can connect to the serverscheck gateway, which is not the case; presumably, if I am not able to ping the device, neither can the nagios server...



At this point, should I consider the thing defective ?

Can you have someone check on it physically for the lights and indicators?
