AP7522 POE issue

[Michael_Wright]

Please help, today i have being setting up and configuring 10 AP7522s i have got 7 all working correctly but for some reason 3 have POE issues they are constantly rebooting and do not say up. I have changed the cable, directly connected the AP tried different POE config on the switchports but nothing.

The switch is providing POE so all i get is the below:

*Oct 16 10:56:16.747: %ILPOWER-7-DETECT: Interface Fa2/0/23: Power Device detected: IEEE PD
*Oct 16 10:56:17.787: %ILPOWER-5-POWER_GRANTED: Interface Fa2/0/23: Power granted
*Oct 16 10:56:22.435: %LINK-3-UPDOWN: Interface FastEthernet2/0/23, changed state to up

*Oct 16 10:58:09.030: %LINK-3-UPDOWN: Interface FastEthernet2/0/23, changed state to up

it just repeats over and over

Please help thanks

Hi Michael,

could you also test only those three affected APs all alone?
Not necessarily this is a PoE issue. Might be DoA AP...

Any chance to get console connection for affected APs?
See description in article here

I tried what you suggested Edmundo but it seems its just reloads again. it's a Cisco switch and there is plently of power available to power the APs, This is happening on two different switch located on the network

Hi,

do you check the power budget?

show power inline

Is it a Cisco or HP switch? Sometimes the negotiation between AP and Switch failed. In this case the AP get full power.

[Edmundo]

You can try to connect through the console port to the
Ap7522 and press the Enter key before loading the system to discard that it is Firmware problem and try to start with the second partition.

If in this mode the AP restarts I would tell you that it is HW problem and I would request an RMA

Tried both commands but I cannot connect to either device to see status they power up long enough before they reboot for example Show adoption history on xxxxxx Error: querying device If I just try show adoption status or adoption history I see aps listed but they show adopted unadopted one after the other. Any other suggestions? Thank you for the help so far!
