Cisco 1700

Question

Not sure if this is the right place to put this. I have just received a used Cisco 1700 router and need help with a couple of things. 1.) It has no console cable. I/we will be configuring the router with a Thinkpad T42 notebook. Is there an easy way to make a console cable. Can I make one to connect thru my ethernet port on the laptop? If so, would I use hyperterminal with TCP/IP option for connection. 2.) I need to reset the settings currently on the router. This includes all passwords, routings, nat. I suppose just wipe the slate clean. Now when I do this, what will be the host address of this router when I connect thru console? Thanks

Hi
Answer No 1)
IF you don't have console cable you can make console cable using CAT5E or CAT6
Cable configuration is written below
*** Use Straight pair configuration on 1 side which is T568B Standard.... and on other side change it reversely like 12345678 on 1 side and 87654321 on other side
1.. White orange
2.. Orange
3.. White Green
4.. Blue
5.. White Blue
6.. Green
7.. White Brown
8.. Brown
On Other Side
1.. Brown
2.. White Brown
3.. Green
4.. White Blue
5.. Blue
6.. White Green
7.. Orange
8.. White orange
Its just like follow the straight pair on both side but change the direction of Connector on one side
Now your console cable is ready...
Now if you don't have Serial connector on your Lap top you will need Serial to USB Convertor As well as Serial to RJ45 Connector( for connecting console cable to router )
Answer For the Host Of Router
"Router by default don't have any Ip Address so you must create a VLAN or you can Assign IP to your VLAN1 and can telnet to router using VLAN1 Ip Address.."
Now if you have done all these things then you are able to connect to your router
Answer No 2)
Now if your router have password protected then just start your router and press Clt+Pause Keys and router will give you rommon mode which is shown below
rommon>
Now write these commands
rommon>confreg 0x42 or 0x32 etc etc
rommon>reset
Now your router will restart and it ask about do you want to change configuration
then just write no and press enter
Now you are in Router's User Mode and you can go to Privileged mode by writing enable command
then write this command
router#write erase " Press Enter"
Now your router is @ factory default setting.
Please Note That
You can connect your router to your computer's Ethernet port but for that router must have Ethernet interface and you must create a VLAN with ip address of your network for pinging your pc to router and vise versa..
Hope this may helps you
