Installing the Cisco WAE Inline Network Adapter

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, 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
.)
