16.2 Ports

The 100BASE-TX SwitchModule uses crossover ports with RJ-45 connectors. The X that follows the port number on the SwitchModule indicates a crossover port.

CoreBuilder 5000 100BASE-T modules use crossover ports. This means that if you connect a 100BASE-T SwitchModule port to another CoreBuilder 5000 100BASE-T module port, you must use a crossover cable.
