Step 6 Connect the network cables to the expansion interface ports. (The inside, outside, or perimeter network
connections can be made to any available interface port on the PIX 525.) The first expansion port
number, at the top left, is interface 2. Starting from that port and going from left to right and top to
bottom, the next port is interface 3, the next is interface 4, and so on. Refer to “PIX 525 Feature
Licenses” for information on how to configure the ports.
Step 7 If you have a second PIX Firewall to use as a failover unit, install the failover feature and cable as
described in “Installing Failover”.
Note Do not power on the standby failover unit until the primary unit is configured.
Step 8 When you are ready to start the PIX 525, power on the unit from the switch at the rear of the unit.
PIX 525 Feature Licenses
If you have the PIX-525-UR unrestricted feature license, the following options are available:
• If you have a second PIX 525 to use as a failover unit, install the failover feature and cable as
described in “Installing Failover”.
• If needed, install the PIX Firewall Syslog Server as described on the logging command page in the
Cisco PIX Firewall Command Reference.
• If you need to install an optional circuit board, refer to “Installing a Circuit Board in the PIX 525”.
• If you need to install additional memory, refer to “Installing a Memory Upgrade”.
Note If, for any reason, you may choose to downgrade to any software version, note that you must use the
clear flashfs command before doing so. A new section is added to Flash memory that must be cleared
before downgrading.
