Although we do have 4148 line cards in the chassis as well, the line card we are using is a 4748.

I know that the 4148 is to old and will not support the new phones may look at the 4748 and see if it supports the new phone

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
