    Not really, I was not aware of that technic and I do not have a multimeter at this moment...

    I'm thinking of buying a new console cable instead of the multimeter, or would you recommend the multimeter instead

    Buy the cable. Wish you would have stated this in the beginning. We would have told you to buy a cable.

    What does your console cable look like? Can you take a picture of it?

    Yeah, my bad, I guess I had to learn it the hard way

    I'll buy it online in the next days, because I couldn't get it at a local store.

    Not very pretty Sure I can, and I will post it in a couple of hours.

    Ps: Please do not laugh too hard, the poor cable has feelings too what up!

    Default rommon

    Have you tried rommon mode?
    A console cable is just a rollover cable, so one side has pins 1-8 and the other has 8-1.

    So do this, keep your computer and terminal program open and connected console cable to the switch. Unplug the switch (to power off) and wait 10 seconds and plug it in. This starts the boot process. Immediately issue control break to the terminal (try a few times and try it early or late in the process if it doesn't break immediately), this will break out of the booting and into the rommon mode. If this works, then your console is working and everything should work if you fix the configs. In this situation, you should stay in the rommon mode, and do the password recovery procedure (it just skips the config file so you can boot in and do stuff).

    These are the pictures of my cable.







    And this is the manual I used for the db9 connector, the RJ-45 side said it could be used a 568B standard, so I did.

    Not really, but bucause I wasn't aware of that! Sounds terrific, I'll google for it and hope to show some results soon enough.

    Hmmm... from the look of those pics your cable might be suffering from some cross-talk. not sure if the copper needs to be exposed that much. also the twist in the wire pairs needs to be shorter... maby a 1/4 inch. This could be your problem.

    sigh... that is an odd looking console cable.

    Yeah... bottom line... You must get a new cable!

    Speaking of which... hehe just kiddin' guys, I'll get a new cable I promise that, I really thought it was okay, I have one borrowed from a teacher (not home made), and gives me the same result, but of course that's not a guarantee, guess I shot myself in the foot

    Ps: I think that would require international shipping

    What's up guys, after so many days, I just received my new brand cisco console cable, I plugged it in to my switch and... Unfortunately I got the same result

    Seems after all to be a faulty console port?

    Sounds like it. Sorry for your loss, maybe post it back up on eBay as in need of repair. Or use it a door stopper!

    Just never turn up to work / customer site with one of those DIY console cables... ever!

    Yes I do, in fact I'm using that switch for a 'mini lab' and gives me 100Mbps through ethernet which is ok

    Don't know, but I'll definitely check that out, thanks for the advice.

    mm not really, looks kind of flawless, what I do notice is that the whole thing moves a bit, don't know if that's normal, but anyways can't hurt to say it I guess.

    I know this thread is a year old, but i just had the same issue with a 2950 (no keyboard input thru hyperterminal) and what fixed it was... ...taking the cover off and wiggling the console ribbon cable where it connects to the main board. Didn't remove it, just moved the ribbon in the connection a bit. Keyboard works great now.
