Cant console into Catalyst 4507

CSCO10992439
Level 1
Level 1

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

and also I cant type anything into the console....

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 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.......
