Cabling

When you are directly connecting two network devices that are different, such as a switch and router, use a straight-through cable.

Note Because the inline network adapter has an internal crossover connection that becomes active when the InlineGroup interface is placed in mechanical bypass mode, you must decide which cable you would use to connect the two network devices directly, and then you must install the other cable type (on one side, usually the WAN side of the inline appliance) instead.

Table 4 shows the cable requirements for WAE and non-WAE connections when you are using Fast Ethernet end to end.

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 20 through Figure 22 show which cables to use for the WAE LAN and WAN connections between Fast Ethernet ports.
