OK I understand, I'll explain a little better for you to understand me
I really think this may be 1) Defective switch and / or power supply on the switch.

I explain
I used to have these devices working without problems

Ports Devices
1. Airfiber 5X
2. none
3. Litebeam 120 AC
4. none
5. none
6. Rocket Prism
7. Rocket M5 TI
8. Rocket M5 TI
9. Rocket M5
10. Powerbeam 500 AC
11. Rocket Prism
12. Rocket M5

The modifications I have made is to change the airfiber 5x (10 W) by airfiber 5U (50W)
Add 3 nanostation M5 that were not previously

Now the temperature levels are well of the unit as it is in the photo I do not know the ideal temperature of the unit
The unit is well-grounded


I will test with another DC unit with an alternating source to test the power to decay that is problem power problem.

For this consumption how many amps must have the source to feed the netonix DC to power these equipments ?

one should use at least a 500w DC power source for a 250w switch. 500W/50V (round math) = 10A.

OK You say the switch is well grounded but is the AC Earth Ground bonded/connected to the tower Ground Rods with a heavy gauge wire??????

You ALWAYS want your Electrical Service Earth Grounds BONDED / CONNECTED to the tower Earth Ground Rods else the Ethernet cable will carry any ground potential differnce between the 2 Earth Grounds which is BAD and can cause weird issues and or damage to equipment.

However with this said I think your issue is your Inverter is either not supplying enough AC power to the switch or is possibly faulty and is dropping AC power to the switch causing the reboot.

What is the model # of your Inverter? And do you have a link to the spec sheet (in English).

With a WS-12-250-DC you should hook the switch directly to your battery bank preferably 24V or higher as it is not rated at the full 250 watts down to 9V.

Ok I understand just to do the test I can use a DC source 48V 6Amp
The inverter is a trace inverter 3000 watt (24V)

Just for a day to see how it goes

Hello solved the problem really it was lack of amps we changed the entire laying and it has not been restarted more thank you very much for your valuable help :cheers:

Hi Chris, I'm taking up the subject again 5 days ago I'm presenting problems with this model that I mentioned earlier (everything was perfect for months working)
The problem is that suddenly the drive restarts on its own

Today I went to check where the unit is installed and all normal electrical power and very good amperage

In fact highlight a test to be sure it is the next test unit
1- Place a nanostation at the same power as the unit is powered with a source amperage only to ensure that there was no power cut and thus have a safety netonix that was the fault. actually the unit reboot (netonix) and the nanostation does not indicate that there is a problem in netonix

I'll send a status screenshot to see if you see something abnormal
will be failing the power supply of this unit I have many complaints since I am presenting cuts to the network
I have seen peak power consumption of the 175.5 Watt unit

From this food unit a Netonix Mini I'm seeing something that caught my attention the voltage of the board that provides the WS-12-250-AC to the WS-6-MINI I see it at 46.2v just like it happens with the 24v is at 23.8
v I was struck by the fact that the 48V part of WS-12-250-AC is falling and that is why this unit restarts





please if you have any idea that it may be happening tele thank you

To be clear you are saying the WS-12-250-AC is rebooting?

It may be possible you are having a power supply failure?
Do you have a spare WS-12-250-AC to swap out the unit in question?

The WS-6-MINI 48V makes sense as you would have voltage drop on the cable. The WS-12-250-AC puts out 50V+/- but by the time it gets to the WS-6-MINI you will lose some voltage so that is normal.

The WS-6-MINI 24V is 23.9V which is normal as the voltage can vary +/- a volt or so.

Why are you powering the AFX radio on port 2 with 24VH????

AFX radios can use 48VH - READ THIS POST:
viewtopic.php?f=6&t=1215#p9040

Please change port 2 to 48VH after you confirm the MAC address of the AFX radio from the above post is fine with 48V.

It is possible the switch board on board 24V power supply is over taxed if all 24V radios were transmitting at the same time. But this would normally cause a 24V radio to reboot not the entire switch. But none the less you should power AFX radios with 48V unless you have one of the very first ones UBNT released that could not use 48V. READ THE ABOVE POST TO DETERMINE IF YOUR AFX RADIO IS FINE WITH 48V.

We recently changed/improved the 24V power supplies to deliver a lot more watts.

Yes confirmed

I suspect that since I had been working well months before

Do you have a spare WS-12-250-AC to swap out the unit in question?
If I just replaced it today

OK well
Why are you powering the AFX radio on port 2 with 24VH????
Previous always use it as well

Please change port 2 to 48VH after you confirm the MAC address of the AFX radio from the above post is fine with 48V.
If I have already done so, it is 48VH now

We recently changed/improved the 24V power supplies to deliver a lot more watts.
Ok it seems much better since most computers are 24 V
I see that Rocket AC PRIS second generation consumes more energy than previous ones

Glad you changed to 48V or 48VH for AFX radios.

Glad you swapped the WS-12-250-AC with spare.

Let me know what happens, if the reboots stop.
