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 1-11 through Figure 1-13 show 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-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 1-18). The WAE can be
physically placed inline between two distinct network paths, creating redundant
WAN links. (See Figure 1-11.)
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 type of
serial cluster configuration, if one WAE fails or becomes overloaded, the other
WAE can provide optimization. (See Figure 1-12.)
Note When you connect two WAE inline appliances to each other in serial fashion,
always use a crossover cable between the two WAEs. (See Figure 1-13.)
