Some switches support automatic medium-dependent interface crossover (MDIX). You can configure MDIX by using the mdix auto global configuration switch command. If your switch supports MDIX, you do not need to follow these cabling rules because MDIX automatically adjusts transmit and receive pairs when an incorrect cable type (crossover or straight-through) is installed on a 10/100 Fast Ethernet port. However, when you configure MDIX, you must also configure the port to use autosense (not manual selection of speed/duplex).

Caution If you are connecting to Fast Ethernet ports on both the LAN and the WAN sides of the WAVE inline appliance, you must consider the types of devices that are being connected, and you must use the correct cables. You must follow these cabling instructions for the inline network adapter to work properly. (See Table 4-3. For illustrations and examples, see the “Installation Scenarios and Cabling Examples for Fast Ethernet Connections” section on page 4-7.)

To connect the inline network adapter using the correct cables for Fast Ethernet connections, follow these steps:

Step 1 Determine the type of cable that you would use for a direct connection between your two end devices (without a WAVE 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.
