Recently purchased a pre-owned PIX 506 running 5.1(2). (I can't upgrade this software since I do not have a service contract).
Although the company I purchased this from reset the password, I want to make sure all their configuration is cleared off and start with a clean slate.
How do I reset a PIX 506 running 5.1(2) to its' factory default? Also, will I need to re enter the activation key if I do this? This was not provided to me.
