Installing a Circuit Board in the PIX 520
To install the 16 MB Flash circuit board, perform the following steps:
Step 1 Record the present PIX security appliance unit serial number.
Step 2 Record the new serial number from the 16 MB Flash circuit board.
Note After installation, the serial number of the PIX security appliance changes to 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).
Step 5 Remove any previously installed Flash memory circuit boards from the unit.
Caution Do not remove or reposition the 16 MB Flash circuit board. The PIX security appliance will not work if
this jumper is moved.
Step 6 Install the 16 MB Flash circuit board into an available ISA slot in the PIX security appliance chassis.
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 security appliance 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 security appliance IPSec accelerator in
the same chassis. The PIX security appliance IPSec accelerator was also known as the Private Link card.
