AP goes offline and requires switch reboot to come online.

[Thomas_Randolph]

We have all AP3605. Current firmware 09.12.01.0067. This has been happening with prior versions as well. They are connected to Enterasys B-Series switches (FW 06.81.01.0027) and occasionally, the AP will go offline with no lights, and I'm assuming no power. I try to turn power off to the port and then back on, but it does not come online. I have also tried in the past moving it to another port on the switch with no fix. What ends up getting it back online is rebooting the switch. Based on that it seems like a switch issue. This is not a regularly occurring issues, but when it does happen it is an issue because I have to bring down the whole switch to fix 1 AP. Any suggestion on where to look or settings to check?

Check with show inlinepower the poe consumption, maybe the power budget of 375W is exceeded sporadically.

Just an idea...

At most there could be up to 20-30 APs. It does not seem to follow any specific AP. Once I reboot the switch, it may never go back offline. It is very very sporadic and just a few devices so far. The install has been in place for about a year with over 500 APs and 2 controllers.

How many access points do you have attached to the B Switch that provides power and is it the same AP every time?
