Hello All,
I have some strange problem while trying to use the console to configure Catalyst 4507, Im using rollover cable, normal serial setting (9600-8-none-1-none). Switch has 2 supervisor engines ( Supervisor II-Plus).
The problem is that, I can see everything on the console, normal booting sequence, IOS image decompression, all messages that show normal synchronisation with the other supervisor engine. then when it reaches the part when it says Press Enter to start, I cant type anything, i still can see all the messages (like when I pull the other supervisor engine out) it gives me the message that it was pulled out, yet I cant type anything. Same thing with the second sup-engine. Unfortunately, Telnet and Aux port are not set, so they are unusable.
Can anyone help please? All suggestions are welcomed.
Thanks

Hi. You can't get that message from a console. That means you are doing something incorrectly.
You might have an authentication method problem on the AUX line, on the router you are remote logging from. Or maybe you forgot to allow login?
Do this on that router (if it's clean running config):
conf t
ena sec cisco
line vty 0 4
pass cisco
login
linex aux 0
pass cisco
login
transport input all
int lo 0
ip add 1.1.1.1 255.255.255.255
end
telnet 1.1.1.1 2017
(the port number for reverse telnet is 2000 + the number that you see from "sh line | in AUX|aux"
Also,
changing configuration register to 0x2102 on the 4507 would be nice

Hi,
Thanks for your reply.
I followed your steps exactly, I got this output
Router#telnet 1.1.1.1 2001
Trying 1.1.1.1, 2001 ... Open

Password:
Password OK
but I cant type anything, everything freezes there.
As for the conf reg, I cant change it, because I cant type anything at all.......
