Serial console alternative

RouterOS Beginner Basics
1

Once upon a time routers had RS232 ports. When they misbehaved we could connect a serial cable and access the console to see why.

Now I find myself with an RB912-UAG that refuses to boot or netinstall. Is there any method / alternative to connect to a console for troubleshooting?

Yes, you can see the routerboard start-up and you can select how the router must startup.
Example select etherboot for netinstall.

In this example see you the start-up procedure but i must this further ullistrate that.

plisken, his board has no serial.

When you say that it refuses to Netinstall, did you follow this procedure exactly like this?

  1. turn off board
  2. push reset button and hold it
  3. apply power to start the board
  4. keep holding button until Netinstall program sees the board (some 20 seconds)
  5. release button

If reset button can’t help, you must return it to warranty repair

Hé Normis, i mis understand his question.
I have no problems with the netinstall procedure.
But have try with serial and working perfect.

Yes, I’ve followed that procedure exactly, and tried variations including hardware short. Totally unusual response - no beeps at all, all lights are on and none go off even after 2m of holding down either reset button. It won’t boot in any fashion and does look like a warranty job, but I’m in the habit of looking at a console before claiming that.
