Cisco 6921 is plugged on PoE switch, patch cord & routing is tested with another phone. But one 6921 phone is stuck on start up process. All Receiver, mute, speaker, headset buttons lights are on but there is no led display.
May u please attach the output of show power inline from the switch to which this phone is connected? Since there is no LED display there can be two possibilites ... Either the phone led has gone bad or the switch port is not supplying the correct amount of power to the phone for boot up.
If other 6921 phone are registering using the same switch port then it seems to be a hardware problem. Moreover you can try to delete this phone from CUCM and try to recreate it using different protocol (using SIP if it was configured as sccp or vice versa) after that you recreate it using the protocol which you want.
Actually phone is not showing led display, and we have to enter cucm alternate ip address then phone will send registration request. Now we have sent the phone to cisco for claim. Thanks for your response.
