Cisco 3911-Keeps Rebooting when connected to POE switch
Cisco 3911 model ip phones,which when connected to an external adaptor is working properly and getting registered to CUCM and the it has latest firmware version as SIP3951.8-1-4a loaded in it.
But when the same is connected with the POE switch it is continuously rebooting.After downgrading the firmware version for the specific 3911 model to SIP3951.8-1-2SR1,when the same is connected to POE switch then the ip phone is properly booting and working as well as registered to CUCM as well.The Call Manager version is 188.8.131.5200-11.
Is there some caveats with regards to SIP3951.8-1-4a,if it is then how the same is booting and working properly when connected to external adaptor.Pl suggest.
