Cicso 4000 as a training tool

Unanswered Question
Apr 6th, 2007

I was able to score an old Cisco 4000 router for free that I hope to use as a training tool. It seems to use to require a null modem cable (25 pin to 9 pin) for a terminal connection (as opposed to the rj-45 to 9pin serial that the newer routers use). I've tried a null modem cable and I'm not getting a Hyperterminal connection (using 9600 Baud, no parity, no flow control, 8 data bits, 1 stop bit). Does the 4000 require a special cable for terminal connections or am I just overlooking something? I've double checked that the serial port (COM1) is enabled, etc.

I can't telnet to any of the Ethernet ports, because I have no idea what their IPs are. I also believe that you need to use the console to reset the password, etc. Any help is greatly appreciated.

I'll try that and see. Won't be able to try in until early next wek and will rate the post at that time.

It was in fact a straight through modem cable (not a null modem vcabel). The Cisco 4000 I have has a DB25 connector for the console, not the newer RJ45. All I needed was a straight DB25 to DB9 cable. Thanks to everyone for their help.
