Hi there
Are you able to get the console access for UC540?
If its stuck in initial configuration dialog say no. Then go enable mode and do a show run and see the running config is available. If you got an ip address then please try connecting to the ip using CAA.
If no config in the router please check the config file in the flash using CLI. Then copy the config to the startup config using
copy flash:UC540W-FXO-K9-factory-8.6.0.cfg start-config
Hope this helps!
Cheers
Rath!
