Dear Members,
I have a Cisco C90 which used to work flawlessly, It is running on TC4.2.3 firmware.
1. One sudden day the ethernet port start to fail. The ethernet cable is connected from Codec's ethernet port 1 to our wall ethernet port point. It shows "no LAN" and we are unable to communicate with the codec via IP.
2. However, if I connect my laptop directly to the codec's ethernet port, I am able to establish a successful connection.
3. Or if I connect the codec to a normal home router, I am able to communicate with the codec too.
4. I have performed xcom factoryreset.
The wall ethernet port point is 100% working because currently I deployed another C90 loaded with the exact config.db file without any problem.
Do I need to RMA this unit?
