Erase all data (factory settings) on Cisco 1700 series Firewall

Hi,

I've got the option to take some old Cisco equipment free from a company that's gone under: These are 1700 series firewalls and 1x Cisco 2600 router.

I need to erase all data - do a factory reset on the devices before i can take them off site.  

Does anyone know how to do this and if not too complicated a quick example.

Very much appreciated


Joni

You can do it both from the console and/or a telnet/ssh session.

You are correct on both. Personally I prefer the console connection because u can't loose network connectivity using that :)

Cheers Ernie,
I'm not too bothered about loosing connection as i will just be using my laptop to do the hardware reset. Right i need to dig about and find out the telnet commands to do this.

Thanks for you help so far

I've just been reading up on this and apparently you can't reset enable passwords using Telnet and i need to do a full erase so i guess this will not work.

Curious what you read.
Write erase removes the whole configuration so that includes any passwords.

you can do erase startup-config and delete vlan.dat and then reboot the router...the whole configuration will be deleted including your password...

Thanks for the info guys.

I've got a 8 port switch now so i'm going to attempt to do this. Can you please confirm that the way i've got it setup will work.

8 port switch - straight through patch cable to laptop Nic and other end to the Cisco ethernet port ( not console )

what next???

Thanks

Give your laptop an address in the same range as the router, telnet to it, log on, enable and give in the commands. That should do it.

Got this working.
Got a console cable made up - used hyper terminal ( trial ver 30 day)
Used Ctrl Break to get into the system and followed the procedure from Cisco on how to reset the enable secret Pw - Changed that and logged in and the reset to factory default part is a doddle.  

Thankyou for your assistance
