hello admin,
the robot boots up with a red LED. somewhen yesterday it was a yellow LED sequence. We had connected the serial USB adapter meanwhile to run the defaults. but now it stays on the red LED shown on the picture

hallo admin,
you're right. thanks for that help. my collegue changed the jumpers yesterday by mistake.
 
when the srv1 boots up, then the 3 LEDs signal booting
on start:  
the sequence runs on the first 3 seconds: (labeld: LED3-LED2-LED1)
1) red (half second)
2) red-yellow-yellow (half second)
3) red-yellow (half second)
then the srv1 is available via telnet and the browser.
 
but the srv1 is still not available on port ip:10001
 

 

Good !!!
 
Next step is to update the firmware.
