Comfort Automation/ Security System Forums

Hi,I have a Comfort II Ultra, 7160. UCM01, 7.119, has ETH03I have 2 ports assigned, one for Configurator and one that my HomeSeer system connects to.Everthing has been working fine for some time.Recenly I noticed that I was not getting a connection through either port. I have a static IP.If I load Comfort Srver Manager, if the ETH 03 is responsive I can see it in Server Manager.
I spent some time looking at the system, the only way I could rectify the problem was to disconnect ETH03 and then reconnect.Doing that cleared the fault for a couple of days but each time it has returned.
Any ideas?

Do you mean y0u disconnect the ethernet cable from the eth03 or dicsonect ETH03 from the UCM to recover?

I disconnect ETH03 from the UCM to recover.

I suspect that it is an intermittent fault in the ETH03qwhat is the serial number>?

There is a sticker on the ETH03 with P093397. Is that the serial?

Yes that is the serial number.
It is about 5 years old
It has probabaly developed a fault. I suggest you purchase the ETH03 submodukle from Laser

Thank you.

Ordered.

I ordered and installed a replacement ETH03. Initially things seemed to have resolved, but now they are back to being as they were with the old ETH03.
Any further troubleshooting tips gratefully received.

If a new ETH03 has the same prolen, then I think it is not a hardware problem with the ETH03There may be a problen with the switch or network cable, perhaps they have intermittent problemsI would do a thoeough check on these itemsConnect the ETH03 direct to a router or anothewr switch etc
