RB 433AH on 5.19 reboots every day?

Sat Sep 01, 2012 2:01 am

The customer has RB 433 AH AP with two wlan cards on it. Six clients are on RB433. They are working in APbridge-stationBridge mode with bridged wlan and lan ports. After Upgrading all APs on V5.19 , RB433AH is rebooting every day in the morning with the message rebooted without proper shutdown. Any suggestion what should I do. Upgrade to 5.20 or downgrade to 5.10/11 or even on v4.X which was before?
Any help?

Sounds like a power or cabling issue to me.
What are you using for power adapter?
How long is the cabling to the unit.
/system health print
See your current voltage.
Same time every morning?

The customer has UPS and for all RB we provide them high power supplies. For all most two years they had AP and five AP bridge connected on V4.x version without any problems (the config was that I bridged all interfaces in all APs with WDS and pseudobridges because they wanted all in one subnet).
Two weeks ago we added another AP client. We upgraded all ROS to V5.19 and made on AP-all interfaces to bridge and on AP clients to station bridge (bridged interfaces wlan and eth).
On AP we have registration list for MAC addresses of AP clients and hidden SSID.
From that day central AP started rebooting. RB is powerd with PoE with some 45m length. It is coincidence or not with software version?
Any idea? I will remotely access to the system at Monday to change something or to see health. Maybe upgrade or downgrade.
Can I downgrade central AP to V4.x and leave client AP to V5.19?

Like I said for all RB we are using AC/DC High-Power adapter 24V / 100-240V and not the shipped adapter.

Isn't 45 meters with passive poe too far? I though it was around a 100ft (30m)?

Can you shorten your cable run?

45 meters is fine if using 24v PSU

in some cases, work much better with my router boards or even a version 4.17 or 3.30.
in some cases I had to also do a downgrade.
And than worked flawlessly
The router boards use flow from 8 to 30 volts but how many amperes your power supplies.
There are still routerboarden or other devices connected to the same power supply?

Just one RB is connected on 1.6A I think. Maybe is PoE injector a problem. But tomorrow I will try downgrading to V4 and see what will happen.

Power supply is normally good, am curious what the result will be behind the downgrade.
I hope for success and keep us informed

IMHO the ROS is not the problem. I've been wrong before though :shock:

Is it rebooting at exactly the same time of day?

What does system health say the voltage is?

I'm curious to see what resolves this.
Could be moisture in the morning, though I don't know your climate.

The AP has registration list for AP clients and hidden SSIDs. All RB are at the same enviroment, hot summer days, the boxes are outside. Like I said after adding another AP and upgrading it started to rebooting every day approximately in the morning from 7-9 AM.
On the AP clients in the logs I can see lost connection and no beacons in that period. After 9 everything is working ok. Until tomorrow morning I cant access the site and AP to see system health. I don't even know why there is a long period when AP is not accessible by wireless. Tomorrow I will wait to see what happens. Strange.

Reboots early morning? Just started? Summer only? Is your power supply regulated?

Here is an unregulated 12V 1A wall wart powering a RB433AH.
Daily voltage report for test on sep/01/2012

23:00 = 15.3 Line voltage = 130
22:00 = 15.2 Line voltage = 129
21:00 = 14.7 Line voltage = 124
20:00 = 14.5 Line voltage = 123
19:00 = 14.5 Line voltage = 123
18:00 = 14.5 Line voltage = 123
17:00 = 14.0 Line voltage = 119
16:00 = 13.7 Line voltage = 116
15:00 = 14.3 Line voltage = 121
14:00 = 14.1 Line voltage = 119
13:00 = 14.2 Line voltage = 120
12:00 = 14.2 Line voltage = 120
11:00 = 14.3 Line voltage = 121
10:00 = 14.5 Line voltage = 123
09:00 = 14.6 Line voltage = 124
08:00 = 14.6 Line voltage = 124
07:00 = 15.2 Line voltage = 129
06:00 = 15.3 Line voltage = 130
05:00 = 15.0 Line voltage = 127
04:00 = 15.8 Line voltage = 134
03:00 = 15.8 Line voltage = 134
02:00 = 15.6 Line voltage = 132
01:00 = 15.7 Line voltage = 133
00:00 = 15.4 Line voltage = 130

Since voltmonitor started on 09:00:10 aug/30/2012
Maximum = 15.8v at 03:00:10 sep/01/2012
Minimum = 13.7v at 16:00:10 sep/01/2012
If you used a 24v unregulated supply, the d.c. readings would be twice that. At 30 volts, that router power supply will shut down until the voltage drops below 30 volts. Note what happens to my voltage input between 7am and 8am. Twice that would be passing 30 volts going down.

Just a thought...

Had similar temp related problem turned out to be faulty power caps on the board

routing just a little bit of the world

Hi, did you get anywhere with this, see my post!

Just started happening to me on a RB433uah, this week..

Power supply ok, power lead 1m long.. 24V.

UPS replaced yesterday.. Upgraded to ros5.20,, still the same--

Completely unrelated to traffic... Temperature mild.

Aug asked. I asked. Nobody answered. What voltage are you seeing in "/system health"? Over 24 volts?

@Mikrotik/RouterBoard crew: This is exactly why the voltage reading in "/system health" has to be more than "kinda a guess" or "that looks about right" as you have stated before in other posts. If it isn't accurate within a couple tenths of a volt, what good is it? Has the accuracy on this improved? Or is it still accurate within a couple volts?

It would look bad for you if the actual input voltage is 29 volts, and "/system health" shows 27. That would show your device shutting down prematurely. :(
