Have a 532 2.9.35 with sr2 and sr5 and a 48v poe was stable for a week no issue upgraded to 2.9.35 on sunday and on tuesday box began to reboot any ideas to fix this or has any one seen this issue we have over 20 aps on 2.9.35 no issue except this box

you can try to check weather your confguration is some how changed or check hardware (statical discharge)

Yes. A 532 without radio cards.

Couple of months old and started rebooting every few minutes. It's RMAd at the moment. I'm waiting for a replacement but lead times in the UK are stretching to weeks.

This whole delivery time thing is becoming a real problem. I could use a lot more of these boards but at the moment I can't get my hands on them within a sensible time frame.

I have two RB532 units that reboot constantly. I have used two different wall wart power supplies but the same problem. I hope there is not a batch of faulty units.

Can you get to a console port? (or is it on a tower)
If yes is there any output before reboot?

Have you tried 2.9.38 ?

Just some ideas....

Yes, I can get to a console port, but nothing is outputted before the system shuts off. In the logs after reboot I see:

system,error,critical router rebooted without proper shutdown, probably power outage

On one of the other RB532 units I had, it showed these same symptoms in both ver 2.9.28 2.9.30. Maybe a BIOS upgrade might help.

Hello all,
since a few days i got the same problem on one rb532 machine.
This machine were running all days long but since a few days it keep on rebooting (without proper shutdown). No other messages available.

Edit: right now version 2.9.38 is running on the machines.


I cannot believe if thats a row of damaged routerboards, anyone got new informations regarding that issue ?

My board was replaced.

Tried it too on a board, that has been working flawless for months. It was fixed with a bios reset and an netinstall

Hey KimC,
did you have the same problem with rebootings every 5-10 minutes ?

If yes, then i could just try that instead of buying a new one...

Do you got any problems writing the configuration back to the router and with license ??

Yes, reboot with short intervals, and I did not have licence problem

Remember to upgrade firmware in the process. I did this before upgrade via the serial interface.

I have another RB532 unit which was working fine for about a week and then recently it started having a problem where it reboots every 1-3 minutes. I upgraded the BIOS to version 2.6 and also upgraded the OS to 2.9.39. Even used two different power supplies.

Any further suggestions would be appreciated. Thanks.
