Chapter 5 WAVE Interface Modules
Installation Scenarios and Cabling Examples for Fast Ethernet Connections
Two WAVE appliances with inline network adapters can also be installed back-to-back in a serial fashion
between two network devices for failover purposes. In this serial cluster configuration, if one WAVE
appliance fails, the other WAVE appliance can provide optimization. (See Figure 5-11.)
Note When you connect two WAVE inline appliances to each other serially, always use a crossover cable
between the two WAVE appliances. (See Figure 5-12.)
