Chapter 6 PIX 525
Installing Failover
Note Both PIX Firewall units has to be the same model number, have at least as much
RAM, have the same Flash memory size, and be running the same software
version.
Step 2 Locate the failover cable (shown in Figure 6-6). This cable is shipped separately from the PIX Firewall
unit. The cable is labeled Primary on one end and Secondary on the other.
Install the cable for the PIX 525 as shown in Figure 6-6.
Figure 6-6 PIX 525 Failover Cable Connection
Step 3 Connect the Primary end of the failover cable to the first PIX Firewall unit, that is, the one you have
already configured.
Note We highly recommend that you use a GE failover link when connecting a PIX 525 with
GE interfaces.
Step 4 Connect the Secondary end of the failover cable to the standby unit.
Step 5 Connect a power cord to the power connector on the rear panel of each unit, and the other end of each
power cord to (preferably separate) power outlets.
Step 6 If you are using Stateful Failover, use one of the following types of connections, that is appropriate for
your system, between the dedicated interfaces on the PIX Firewall units:
Category 5 crossover cable directly connecting the primary unit to the secondary unit.
100BaseTX half-duplex hub using straight Cat 5 cables.
100BaseTX full duplex on a dedicated switch or dedicated VLAN of a switch.
Note All enabled interfaces must be connected between the active and standby units. Only
configure the active unit. On a PIX 525, the active unit is indicated by the ACT LED on
the front of the unit.
