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 4-2and Figure 4-3show 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 or becomes overloaded, 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.)
