RB112 starting up provides the following beeps:
one beep when board is switched on,
two beps when RouterOS is booted up.
You can connect null modem cable to check it out, what happens during bootup process.
sergejs, yes but what does 3 or 4 beeps on startup mean - is it always indicating an error? meaning I should connect a serial port, or can I look at the device’s log?
