Access Points Low Power Issue

VineeshVijayan — Mon, 02 Aug 2021 06:12:03 GMT

Hi Experts,

I'm getting multiple alerts from Prime regarding the issues in Access points. below is the log message.

''Message: Access point 'XXXXXX' associated with controller 'XXXXX' draws low power from Ethernet. Failure reason: 'The AP draws 15.4 watts from Ethernet'. (6 times)''

The access points are working before without any issue, this issue is started recently.
Please provide any solution to this.
Thanks in Advance!

- Could be a controller-bug, for that check if the message is duplicated in the controller-logs (too).

Is this error message coming out of Cisco Prime Infrastructure?

What is the AP model and what POE standards does the switch support?

since your switch is POE+ capable, pls check your switch POE budget and it's consumption. If they are within limits then you may ignore this error messages.

Only time I have seen this messages were when a 3700 connected to a 3560 switch which was only delivering af.
