Hardware Features

To connect the inline network adapter using the correct cables for Fast Ethernet

connections, follow these steps:

Step 1 Determine which type of cable you would use for a direct connection between

your two end devices (without a WAE inline network appliance connected

between them) by using the following standard cabling rules:

• When you are directly connecting two network devices that are similar, such

as two switches, use a crossover cable.

• 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 figure out 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 1-9 shows the cable requirements for WAE and non-WAE connections when

you are using Fast Ethernet end to end.
