Recently I installed 2 computers to a 10 computer Network. I quickly found out that the Office had a Pix 501 Firewall with 10 user Licenses. I then purchased the 50 User Activation key from Cisco for this unit. Unfortunately the unit has software version 6.1 which does not support the activation-key command. I have reviewed the documentation from Cisco on how to use a TFTP server (which I have and installed) to upload the binary file and then it will let me activate the new key. All of the instructions seem easy to follow, but the very first instruction has me confused. the first command is to Copy the binary image file (pixxxx.bin) to the root directory of the TFTP server. My Question is where do I get this Binary image file ? The CD's that came with the unit are only documentation, and I can not find on Cisco's website any image download's. So how do I find or get this file so that I can download it to the Firewall and then enter my new activation key ? Any Help is appreciated.
