Installing a Circuit Board in the PIX 520
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).
Step 5 Remove any previously installed Flash memory circuit boards from the unit.
Step 6 The jumper on the PIX Firewall 16 MB Flash circuit board must not be removed or repositioned. The
PIX Firewall system will not work if this jumper is moved.
Step 7 Install the 16 MB Flash circuit board into an available ISA slot in the PIX Firewall chassis.
PIX Firewall VPN Accelerator Circuit Board
The VPN Accelerator (PIX-VPN-ACCEL) is an encryption and accelerator circuit board. The VPN
Accelerator uses a PCI interface and therefore can only be installed in PIX Firewall platforms with PCI
slots. The VPN Accelerator begins to function immediately after installation without the need of special
installation configurations.
Note The new VPN Accelerator cannot be used with the former PIX Firewall IPSec accelerator in the same
chassis. The PIX Firewall IPSec accelerator was also known as the Private Link card.
An illustration of the VPN Accelerator is shown in Figure 5-22.
