Swithc will not give inline power to AP

[pndennie93]

Have a 3560 switch with 2 AP's and several VOIP phones attached. When I add a new AP I do a sho power inline and the AP shows as "CiscoPD" I have done a debug ilpower event and debug ilpower port and it seems to get to the detection but never finds out what it is. Any ideas?

Appologies, please discard my point of using AC as power source I was looking at a similar error mesaage on the release note.

Is the AP powering up but the radios are down or it is not even powering up? If AP is up but radios are down then all you need is to login to the AP and add the command "no power inline negotiation prestandard source" that was suggested by Michel.

Hi Neel,

Probably you have to give the following command on the AP.

no power inline negotiation prestandard source

Otherwise you have test with some power inline commands.

We cannot even get to the AP's it does not show up in CDP and I cannot ping it from the Local LAN. When we plugged our spare into another port and configured the port for the AP we could see the lights on the AP but received the same condition as the AP attached to f0/48. Have a TAC case open. I am afraid to reload this switch at this time because there are a number of VOIP phones attached and a few other AP's that are working. My next step is to send a new switch have it replaced and get it back to our lab.... Appreciate all the input so far...

Hello,

The Aps are 802.3af compliant. The switch doesn't look like it is over subscribed with phones or devices that require inline power. This is now getting to a stage to be a hardware defection. When you plug the AP in port 48 you said you see lights on the AP. Can you connect a console to the AP and check what you get on the console?

Thanks,

Have had our gentleman out there again and no we do not see lights on the AP. We also sent him a non POE switch and a power injector and still no power to the AP. The logg from the POE switch does show that it see the power request but never detects what the device is. TAC case is going slow so I am configuring a new POE switch to be sent and we are having the cable to the AP tested and or replaced. Thanks for all the input.

Hello,

Did you try to use the power supply used by the AP? Could be damaged AP?

yes swapped multiple ports, power injectors and AP's same connection still comes up bad.....

Hi,

Have a look at this link -

http://www.cisco.com/en/US/docs/wireless/access_point/1240/installation/guide/124h_c3.html#wp1059924

Refer to Table 3-2.

Check if your switch supports Intelligent Power Management and then check the configuration on the AP and the switch according to table 3-2
