Chapter 4 WAVE Inline Network Adapter
Installation Scenarios and Cabling Examples for Fast Ethernet Connections
For example, if you are connecting a router and a switch (two different
devices) through the WAVE 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 WAVE
inline appliance.
Figure 4-2
and
Figure 4-3
show which cables to use for the WAVE LAN and
WAN connections between Fast Ethernet ports.
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.
Two WAVE appliances with inline network adapters can 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 4-2
.)
Note
When you connect two WAVE inline appliances to each other serially, always use
a crossover cable between the two WAVE appliances. (See
Figure 4-3
.)
