Cisco Systems 611 manual Router a

Chapter 1 Introducing the Cisco Wide Area Application Engine

Hardware Features

Two WAEs with inline network adapters can also be installed back-to-back in a serial fashion between two network devices for failover purposes. In this type of serial cluster configuration, if one WAE fails or becomes overloaded, the other WAE can provide optimization. (See Figure 1-18.)

Note When you connect two WAE inline appliances to each other in serial fashion, always use a crossover cable between the two WAEs. (See Figure 1-19.)
