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

Can you check, how many watt the APs use and what class the APs report?

Please see attached a video of the console boot you can play this back on tera term, let me know your thoughts

Michael,

if these APs are not stable enough to check configuration there is no way to try i.e. factory reset.

I'd personally recommend to RMA those affected.

I believe the first time they booted they spoke spoke to the NX6500 as its reports the switchports they are connected too, but they seem to no longer do that.

I have tried different switch ports/switches and still getting the same problem.

I believe it could be hardware as well, but i just thought it seems to much of a coincidence that three all have the same issue.

Michael,

I do see important event "NSM-4-IFDOWN" which basically means that port is shutdown and that is why AP goes into reboot.

There is good minute and half gap between first and second PD signature in above log, which means AP boots and operates for certain amount of time.

I do wonder if there is any configuration present on affected APs.
Are those getting adopted when booting or are those standalone?
Also, are every time same APs showing the problem? Different ports on switch?

I do smell hardware issue here...

Regards,
Ondrej
