We have lost the password of our 3c16900 switch, we can connect to the switch using the console port or the network, however for reconfiguring the switch we need to reset the username/password of the switch since those were lost. 3com will be charging us $450 for the service, we're wondering if there is any other way or if it is even possible without damaging the switch.

I see no one has tried to answer this. 3Com will charge you the big bucks, because they know that no one else can help you. They have either a back door into your 3Com switch, or a utility to rip or change the current password. They will want you to pay for the use of that utility, or for a tech to come to your site to do the work.

Suggestion, If you know the settings on your switch, all the parameters, etc. why not reset the switch to factory settings? There surely is some method to reset the unit back to factory specs. Then you can go in, make the modifications you want, and at the same time, set up the password as you want.

Best of luck

Allas, we've tried that one.... It didn't work, there is no way to reset the swich configuration, we've even tryed flashing an upgrade we found on the 3com site. We suspect they will clear/replace the complete cmos of the switch. There seams to be some sort of diagnostics connector inside the switch. All in all it's verry lame having a 100mbit switch with all ports running 10Mbit fixed....

Thanx anyway.
