AP restarting in a single room of the building

AP restarting in a single room of the building

Good afternoon!
I'm serious problems in my ruckus wi -fi environment.
I have a ZD 1106 with 23 APs ZF7372 .
What happens is that two APs from just one locality are restarting and consequently disconnecting users.
Already tested network, energy and until we make the exchange of a healthy AP by one of these APs with the problem and to my surprise the AP healthy this same locality began to have the same problem of APs that were before in this same location .

Viewing the Logs noticed that after restarting the controller shows the Feedback .

AP [ JAC - Floor North ] warm boot successfully , last reboot reason [ power cycle ] .

I ask for help Ruckus community because I'm about to lose my job because of not solving this problem

I am grateful for everyone's help .

att,
Rodrigo Soares

Are you absolutely sure this isn't a POE issue? Sure sounds like a switch that's having trouble powering the AP under load.

A "power cycle" is the restart reason I get if I simply unplug my AP and plug it back in. This seems strongly indicative that you either have an ethernet cable integrity issue, a PoE switch that's flaky (either always or under load), etc etc etc.

Hello people.

in my environment the APS are connected directly to the power supply . We do not use POEs here. on the cable even redid the ethernet cable and also put the antennas this same floor in the same environment of antennas that are not giving problem, in my case is the first direct network switch where also the parent company is located .
Really do not know what to do and what tests we run .
My idea is that energy is something to do , however I have no idea how can I test .

Are you saying you use a power supply that feeds the DC input jack on the AP, or are you using a POE injector? In either case, you DID try a new power supply, right?

Not to mention ruling out that AC power in that room is unstable. The power supply could very well be good too.

The most common problem is the power supply.
I think that changing the power adapter (to a 100% stable from another AP) and using the UPS will help.

This sounds indeed like a power supply, or most probably the cable or jack plug on the end of the cable. I have had this issue once with a power supply. Exactly the same symptoms as you have noticed, changed AP's and the problem persisted, Then I checked the power supply and it turned out to be the 90 degree plug that was not making good contact, by merely touching the wire where it joined the plug I could cause a power cycle.

Finally found the problem. After several tests had the brilliant idea of changing the voltage of the electrical distribution. We have been before placing the AP in an electrical network 110v which in my opnion was absolutely unstable . The diagnosis I had is that when we were all active classrooms ( the environment is a college ), the energy began to fail.

To this end , we decided to increase the voltage on AP plugged to 220V ( the antenna is bi- volt ) , and I did not have more falls .
The antenna had more than 140 simultaneous connections without any fall or restart.

Thank you for personal help , you guys have been very important for solving the problem
