[cisco-voip] 8841 no power connecting to 4510/4748

[Hendrix, Bill W. - US]

CDP is enabled.  Below it the POE for the interface.  Most ports show as "off" until the phone is detected.  Like I said, 7962s working fine.

Bill,



Verify that CDP and power inline auto are enabled from the port configuration perspective then from the enable prompt, what is the available/used wattage output of "show power inline"?



Thanks,



Ryan

Hey guys,



  I am testing an 8841 on a switch we have, but the switch doesn't seem to be detecting the phone.



Phone info:

8841 - sip88xx.11-5-1SR1-1.loads



Switch info:



Switch WS-C4510R+E

Supervisor: WS-X45-SUP7-E (03.04.05.SG.151-2.SG5)

WS-X4748-RJ45V+E version 1



I also tested it in a WS-X4148-RJ45V slot, but it also doesn't work.  Phone powers up fine connecting to a 3560G running 15.0 IOS.





Thanks,



Bill Hendrix
