Figure 7-13 PIX Firewall 16 MB Flash Circuit Board
You must observe the following when installing a 16 MB Flash circuit board:
• The PIX Firewall must have a minimum of 32 MB of RAM memory.
• You must obtain a new activation key if you use 3DES.
• The PIX Firewall should not be downgraded to a software revision lower than 5.0(3) after the new
software from the 16 MB circuit board is installed.
• If you downgrade from software Version 5.3 to 5.2 or lower, you will lose private data (keys,
certifications, and CRLs) that are stored in Flash memory. You need to use the clear flashfs
command, downgrade 5.0 | 5.1 | 5.2 options if your PIX Firewall has 16 MB Flash memory, private
data stored in the Flash memory, and you used the ca save all command to save these items in Flash
memory.
Complete these steps to install the 16 MB Flash circuit board:
Step 1 Record the present PIX Firewall unit serial number.
Step 2 Record the new serial number from the 16 MB Flash circuit board.
After installation, the serial number of the PIX Firewall is the serial number supplied with the
16 MB Flash circuit board.
Step 3 Create a backup of your present configuration (to use later to reconfigure your system).
Step 4 Obtain a new Activation key (if using 3DES).
