  1. Hello from Paris,
    I just got 2 Cisco 1841 and after successfully turn it to its default factory settings with :slight_smile:

    rommon 1>confreg 0x2142
    rommon 2> reset
    router#>reload
    

    answering no to “do you want to save configuration”
    After that I rename the router in Router1 with ip on fa0/1 192.168.1.253 255.255.255.0
    As I got a message in loop

    *Jan 1 00:26:44.271: %ENVMON-3-FAN_FAILED: Fan 1 is malfunctioning

    I got rid of it by Router1(config)#no logging console
    And finally saved the config by Router1#write
    and Router1# copy running-config startup-config
    And guess what happens when I turn power off ?
    I get the following message as if nothing was saved

    Cisco 1841 (revision 6.0) with 176128K/20480K bytes of memory.
    Processor board ID FCZ1023249G
    2 FastEthernet interfaces
    DRAM configuration is 64 bits wide with parity disabled.
    191K bytes of NVRAM.
    62720K bytes of ATA CompactFlash (Read/Write)
    
    
         --- System Configuration Dialog ---
    
    Would you like to enter the initial configuration dialog? [yes/no]: no
    
    Press RETURN to get started!
    *Jan  1 00:28:14.283: %ENVMON-3-FAN_FAILED: Fan 1 is malfunctioning
    *Jan  1 00:28:44.287: %ENVMON-3-FAN_FAILED: Fan 1 is malfunctioning
    *Jan  1 00:29:14.291: %ENVMON-3-FAN_FAILED: Fan 1 is malfunctioning
    *Jan  1 00:29:44.295: %ENVMON-3-FAN_FAILED: Fan 1 is malfunctioning
    **Router>**
    

    Question : do you think the malfunctioning fan could be the cause of the impossibility to copy running config into startup-config ?
    Did I miss anything else ?
    Kind regards

  2. Hello Laz,
    1.Connection throught console using Putty
    no logging console is one of the first cli commands that I learned !

    2.Before saving, show running-config and show startup-config display exactly the same
    Normally since Ram is different from Nvram, it should display different results.
    Anyway, afer Router1#copy running-config startup-config and or Router1#write
    Naturally nothing’s changed.

    3.As you said I changed hostname router to Router1 with no logging console and ip address

    Router1#write
    Building configuration...
    [OK]
    Router1#show run
    Building configuration...
    Current configuration : 589 bytes
    version 12.4
    service timestamps debug datetime msec
    service timestamps log datetime msec
    no service password-encryption
    hostname Router1
    boot-start-marker
    boot-end-marker
    no logging console
    no aaa new-model
    resource policy
    ip cef
    interface FastEthernet0/0
    no ip address
    shutdown
    duplex auto
    speed auto
    interface FastEthernet0/1
     ip address 192.168.1.253 255.255.255.0
     duplex auto
     speed auto
    no ip http server
    no ip http secure-server
    control-plane
    line con 0
    line aux 0
    line vty 0 4
     login
    scheduler allocate 20000 1000
    end
    

    Now for control this is the startup-config

    Router1#show startup-config
    Using 589 out of 196600 bytes
    version 12.4
    service timestamps debug datetime msec
    service timestamps log datetime msec
    no service password-encryption
    hostname Router1
    boot-start-marker
    boot-end-marker
    no logging console
    no aaa new-model
    resource policy
    ip cef
    interface FastEthernet0/0
     no ip address
     shutdown
     duplex auto
     speed auto
    interface FastEthernet0/1
     ip address 192.168.1.253 255.255.255.0
     duplex auto
     speed auto
    no ip http server
    no ip http secure-server
    control-plane
    line con 0
    line aux 0
    line vty 0 4
    login
    scheduler allocate 20000 1000
    end
    

    4.Power off and on and it comes back with the message
    Would you like to enter the initial configuration dialog? [yes/no]
    with prompt router>

    What do you suggest ?

  4. Hello Laz,
    For my lab, last 1841 bought has a problem with CF 64MB memory card.
    Would it be possible to format it to make it readable for 1841 IOS and then what file should I copy into it ?
    Or you suggest to buy another CF card ?
    Thank you in advance
    Kind regards from Paris

  5. Hello Austin

    Concerning attempting to install an unsigned version of the console driver, this seems to be more of an OS problem. I haven’t faced it myself, but after a bit of research, there are two ways to get around this.

    The first is to download and use various programs that have been created for this purpose. This is not generally recommended, unless you absolutely trust the publishers. I won’t say any more about this option however.

    The second (and somewhat more recommended) option is to disable Windows’ requirement for installing signed drivers. You can do this by using the Local Group Policy Editor. You can use your favourite search engine to find out more about how you can do that. Just be sure that the driver is indeed from Cisco before disabling this feature and installing it, and make sure you re-enable the feature once installation is complete.

    Beyond that, you can attempt to manually install the most up to date version of the driver rather than having the automatic update attempt to do so.

    I hope this has been helpful!

    Laz
