Installation Scenarios and Cabling Examples for Fast
Ethernet Connections
WAVE appliances can be installed physically between two network devices (such
as the branch office router and branch office LAN switch) by connecting the
WAVE inline network adapter ports to the network devices using the proper
cables.
If you are connecting a WAVE inline appliance between two devices using Gigabit
Ethernet, you can use either straight-through cables, crossover cables, or any
combination of the two cable types, regardless of the type of device. This section
shows cabling examples for Fast Ethernet connections only, because Fast Ethernet
has specific cabling requirements.
The inline network adapter has four ports that are divided into two inline groups
(see the
“Ports and LED Indicators” section on page 5-3 ). The WAVE appliance
can be physically placed inline between two distinct network paths, creating
redundant WAN links. (See
Figure 5-3 .)
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 5-4 .)
Note
When you connect two WAVE inline appliances to each other serially, always use
a crossover cable between the two WAVE appliances. (See
Figure 5-5 .)
