Hi all

I have got a simple question:
How to inform Routerboard that buffered power supply unit is getting power from DC batteries not from AC?

It would be a quite useful thing to know that there are problems with AC.

How do You solve that kind of problems?

You must use routerboard with measuring Voltage.
Then you can show (graphs) input voltage over SNMP

HTH,

It's too expensive ($25 for only information, Is the AC power ok or not).
I think, there should be other - simpler method.

If you use 2 PSUs, one into the Jack and one into the POE you can feed the RB from 2 different voltages.

If you feed 24V from the mains supply, and 12V from the UPS you can then use the voltage monitor to see which one is being used.

Better solution but...

After a long while of thinking about it...

Is there any option to monitor mains supply status by:
- ethernet status port (port is up, supply is OK, down....NOT OK)
- rs232 (if down there is some other signal on rsr232 and mikrotik shows sth in logs)

I could add ip address to that port or dynamic route and monitor it by ping....or just look for this in logs
Simply? But what connect to eth or rs232?

Does somebody try to do this in that way?

Find old, unused but working device with ethernet port.
Power it from mains supply and connect to RB.
You can use Netwatch to ping this device and run scripts on up/down events.
Or check RB ethernet port status (is running/link OK) with scheduled script.

HTH,

I do this in this way right now.

The ip interface is not needed anymore when I can monitor eth port status.
So I think it could be cheeper, no power consuming and much smaller (like a thumb?)
