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

1000SXfull—Forces full-duplex operation
•
1000BaseSX—Forces half-duplex operation
•

Note
We highly recommend that you use a GE failover link when connecting the PIX 525 with GE interfaces.
