Use a crossover cable to connect two ports when both ports are designated with an X . The following sections describe the supplied rollover console cable and adapter for the console port. You can identify a rollover cable by comparing the two modular ends of the cable. This section provides cabling guidelines for building networks using the FastHub 400 series and other repeaters. Class II repeaters support longer cable segments in single repeater configurations than Class I repeaters.
Many switches have internal repeaters or plug-in repeater modules.
In this type of device, the switch is actually attached to a port on the internal repeater. If the port is a Class I repeater port, do not connect the FastHub 400 series or any other repeater to the port. G eneral Guidelines for Ethernet Networks Table B-4 describes some guidelines when creating Ethernet networks with multiple repeaters. Exact figures could vary, depending on the manufacturer of the network equipment. The IEEE 802.3u standard specifies network configurations using Class II repeaters.
