Installing a Circuit Board in the PIX535
Step 5 Remove any previously installed Flash memory circuit boards from the unit.
Step 6 The jumper on the PIX security appliance 16 MB Flash circuit board must not be removed or
repositioned. The PIX security appliance 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 PIXsecurity 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.
An illustration of the VPN Accelerator is shown in Figure7-14.
