Chapter 1 Introducing the Cisco Wide Area Application Engine

Hardware Features

Step 2 Connect Fast Ethernet ports on both the LAN and the WAN sides of the WAE inline appliance by using the following cable types:

On the LAN side of the connection, use a straight-through cable between the WAE inline appliance and the network device.

On the WAN side of the connection, use the cable that is different from the cable that you would use to connect the two network devices directly (as determined in Step 1).

For example, if you are connecting a router and a switch (two different devices) through the WAE inline appliance, use a straight-through cable on the LAN side of the connection and use a crossover cable on the WAN side of the connection. (If you were connecting the two different devices directly, you would use a straight-through cable, so use the crossover cable instead.)

If you are connecting two switches (or two similar devices), use straight-through cables on both the LAN and the WAN sides of the WAE inline appliance.

Figure 1-13through Figure 1-15show the cables to use for the WAE LAN and WAN connections between Fast Ethernet ports.

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-throughcables, 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 1-16). The WAE can be physically placed inline between two distinct network paths, creating redundant WAN links. (See Figure 1-13.)
