I am see "No Lan Acitvity" message on the EX90 touch panel but the endpoint is connected to LAN and able to establish video calls.
Endpoint is registered to VCS SIP-H323
Firmware 7.3.3
Recent change in environment is, turned off and uninstalled the device for 2 days to reburish the furniture and install the device back.
Troubleshooting:
Reboot
Factory Reset
Network Ports swapped in switch side
Replaced cat5 patch cord
