  • Problem with Cisco Router

    Hi!

    I have a problem with Cisco router model 1601R.
    I've attached my laptop to the router using two cables: ethernet and console.
    Using Hyper Terminal, I connected to the Router, configured it and saved the configuration: copy run start.
    After that I restarted the router (I kept Hyper Terminal program running on my laptop). It worked well. I was able to ping the router.
    Then, I've closed Hyper Terminal, disconnected the console cable, so that the
    router was connected to my laptop via ethernet cable only. And it didn't work,
    system ok indicator was flashing. When I've attached the console cable back to the router I found that the router started in Rommon mode. Then I restarted the router again with opened Hyper Terminal and it worked with my configuration.
    What I do not understand is why the router starts properly only when Hyper Terminal is opened on my PC ?
    I've tried to configure the router via Hyper Terminal and copy router config and IOS on tftp server on the laptop - it worked great. the only strange thing - the IOS file was without extension *.bin, not sure if it is important.

    thank you in advance,
    Mihail

          Re: Problem with Cisco Router

          Hello,

          I've tried to fix the problem:

          1) I erased all files from flash and nvram
          2) restarted the router and made sure that flash memory was empty - no files found on flash
          3) I've configured an ip address on the interface e0 and used "copy tftp flash" in order to copy IOS (this is the original IOS from this router which I saved before on laptop) to flash memory and then restarted the router again.

          Result: I can boot the router when Hyperterminal is opened on my laptop and I still can't boot the router when laptop is desconnected from the router (I get rommon prompt).
          regards,

            Hi !

            I've found another cisco router, that one was exactly the same model as the broken router - 1601R.
            I put the flash from another router in the broken router.

            Now I am getting the same results as before: Everything works fine when the router is connected to my laptop and I have Hyperteminal opened on the laptop. I can reboot router - in Hyperterminal I can see the booting process - all looks good.
            I made sure that startup configuration is actually exist in the router by using the following commands: sh start and dir nvram:

            but when I close Hyperterminal on my PC and restart the router, it doesn't boot up. Instead, I get "system OK" flashing and when I open Hyperteminal on my laptop, I see rommon prompt.

            I am not sure what else I can try to do in order to fix this problem...

            any ideas ?

            Thank you!!!
