Cisco PIX 501 - reset to default?

Howdy Experts!

I recently found a Cisco PIX 501 Firewall at a garage sale (for only $1) and brought it home.  It appears to work fine, but I would like to reset it to factory defaults.  Is there some special combination of buttons I can push to accomplish this?  The documentation refers to the config pages....but I don't know the device's IP address or any passwords that might be on it.  

Thanks in advance!

Hey Thorin

Here is the procedure to do a password recovery on a PIX:

http://www.cisco.com/warp/public/110/34.shtml

If you can already logon to it and want to remove the configuaration:

write erase
and then

reload

That will wipe the config and then let you configure from scratch.

nodisco,

How do I connect to it to do this?  I don't know the IP to connect via telnet or HTTP.  Do I need the 'console' cable?  Many devices I have seen have a way to hold down the power and press a reset or something.  This device doesn't have that?

Okay....I got a console cable, connected it, and now I am talking to the device.  One down!

So now I have gone back to the document you first posted...and I am stuck on the TFTP stuff.  I have gotten the connection going, set up my TFTP server, and uploaded the file.  But it stops there.  In the document you reference (under "PIX without a floppy drive") it stops at step #10 - I never get the prompt described in step #11.  HyperTerminal shows "Received 110592 bytes" but nothing happens after that.  Is there some 'execute' command I need?  

I am a little concerned I am using the wrong reset file.  When I boot the device, the terminal session shows "Embedded BIOS version 4.3.200" so I assumed that meant I want "nppix.bin".  Is that the right way to determine the version?  

Thanks for all your help on this.

It does sound like you have the wrong version file..
Let the pix boot up and at the prompt:
pixfirewall>sho ver
This should show you which version you are running. 6.x

Wahoo! That was it....wrong version.  Once I got the right one, resetting the passwords was a snap.  Thank you so much for your help.  Once again experts exchanges makes it look like I know what I am doing!!!

hi Thorin

Glad you got working - I suggest you split the points on this Q as it was a dual effort!
If you are happy to do so - Lrmoore can reopen the Q or you could open a question with Community Support.

cheers

Oh!  You are right!  I did not even notice there were two of you on this.  I apologize!  

I suppose the argument could be made that you provided the answer to the original question in your first link.  However, without lrmoore's information about the console cable and the version, I would never have gotten there.  A point split sounds fair to me....

lrmoore, can you make this point split change?
