Cabling

Installation Scenarios and Cabling Examples for Fast Ethernet Connections

WAE appliances can be installed physically between two network devices (such as the branch office router and branch office LAN switch) by connecting the WAE inline network adapter ports to the network devices using the proper cables.

If you are connecting a WAE 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 3). The WAE can be physically placed inline between two distinct network paths, creating redundant WAN links. (See Figure 20.)

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 serial cluster configuration, if one WAE fails or becomes overloaded, the other WAE can provide optimization. (See Figure 21.)

Note When you connect two WAE inline appliances to each other serially, always use a crossover cable between the two WAEs. (See Figure 22.)
