RouterBOARD 450

Hardware MikroTik hardware general
1

I have a fairly new Mikrotik that seems to be boot looping. I have had it for a few months and it has been working well. 2 days ago it totally locked up. I couldn’t get DHCP from it or ping it. I didn’t have a serial cable so I couldn’t check that at the time. It was at a customers site and I went ahead and rebooted it. I had to replace it because it continued to be unresponsive but in a strange way. It would not give out DHCP but I could telnet and use the installable management interface on one of the ports. The other ports were unresponsive when I assigned an IP in the subnet that they were in. I just now booted it up with a serial cable attached and I get what you see below. It will continually select options and it just keeps scrolling waaaaay to fast for me to even attempt to read anything it is saying. Any ideas whats going on? I have also attached a large text file with more of what it’s printing to the console.

Thanks in advance.

Try to reinstall the RB450 via Netinstall,
http://www.mikrotik.com/testdocs/ros/2.9/guide/netinstall.php
Set boot from Ethernet to boot devices of the RouterBOARD, follow the guidelines from the documentation link.

I thought about doing that but I can’t set the boot to anything. All of the random options that you see being selected above are not being selected by me. The serial console is completely flooded with those options and it never stops displaying->selecting->redisplaying the options. Is that normal?

No, it is not normal.
Try to get another null modem cable,
try to disable hardware-flow control on the Terminal program and try to operate with RouterBOARD BIOS once again.
