need good info on configuring a Superstack II 457 router

[cm]

I have a frame relay connection between two 457 routers.<br>
site A site B<br>
frame port V1 frame port V4<br>
<br>
I need to set up the router to automatically use a ISDN dial backup recovery connection when the frame is down, and automatically terminate the ISDN when the frame is up again.<br>
I have a 3ComImpact IQ ISDN modem in each site connected to the port 4 of the routers.<br>
<br>
Any source of info, (web, books, CDs) would be of grat help.<br>
The router manual is limited.<br>
Tried 3Com, they gave me some macros to enter; I wonder if there is an easier way. Thanxs

How do you remove a password or default a superstack switch 9300? The backdoor password debug has been changed so that will not work.

Hi !

So I´ve got the same problem with my 3com SuperStack II 9300 (PID 3C93011).
Here is no way for any matrix-modul ! I couldn´t connect the cable. So what can I do now for the reset to factory settings ?
NO given password (above) will work ! And we lost the administrator password !

Please gimme some hint and/or solution !

Thx.

Andrew.
