PIX 535 Rear Panel
The PIX 535 also supports a VPN accelerator card (VAC and VAC+). It should be installed
only on the 32-bit/33-MHz bus.
The console connection for the PIX 535 is the same as for the other PIX models.
The three licenses available for the PIX 535 Firewall are similar to those available for the PIX
515E and 525 but support a greater amount of RAM and more available physical interfaces.
Upgrades are available to implement VPN hardware (VAC or VAC+) support. PIX OS
version 6.3 supports logical interfaces and VLANs. Table 3-6 describes the available licenses
and their functions.
