Hi all, I have a problem with this switch, but took too much time asking teachers, friends, ... I even posted in various forums before (I did not know your forum ... if not, you were the first   .

This switch had a power problem, I got to repair the power, and now the fans start to connect, power lights, blink console ... if I connect a serial cable with putty see the bootloader but I can't activate the console (shif +6, esc, or others ...) or connect by ip, has none. Just get the following:

What can do with them?   not how to use them, I guess that they are part of the bootloader, I know how to:

continue the normal load of firmware or
reset or
allow me to upload new firmware.

Thanks to all, suggestions are accepted ...

Not same model however same family. I recommend contacting DLink support regarding this issue.

[wondernet]

At the time I thought of contact, but is no longer under warranty and I'm not the ultimate purchaser, the team comes from a donation from a friend (or revenge ), And I always thought he had already taken steps to contact (or maybe not? a long ago I dont see), in fact the team would be sent for recycling. So as part of my studies (CCNA, routers ...) I thought it would be interesting to learn something else. But following your advice I will try to help (hopefully free) D-link support of my country.

However, to complete this question, I'll put the answers below are obtained with some of the commands that allows:

Well, while find a solution to revive it, now I have a utility to switch, I put on two shelf brackets and used to pile my books to study, is original and in keeping with a modern and functional environment Ti

Thanks and greetings to all the folks, who bother to read this incomprehensible post until the end.
