Hi everybody inm this forum. I work with many nortel devices at work, here's what happened yesterday: we have a Nortel BPS 2000 and we couldn't enter trough telnet(we had to change the paccess password), so i decided to actually go where this switch is located, connected nmy laptop to the BPS, made the password change ( cli password read'write xxxxxx, cli password telnet local, exit) ; everything worked perfectly and i was able to enter with this new password trough telnet. The thing is i tried a couple of times more, and all of the sudden i couldn't enter again, all i have is a blank screen, no nortel menu, nothing. I tried with the Device Manager and the switch is operative, but i can't enter trough telnet. Hope i can get an answer about this.
