Installing the HSSI Module
CAUTION: Connections between 3Com equipment and other equipment and peripherals must be made using shielded cables in order to maintain compliance with FCC, and other agency radio frequency emissions limits. All interconnection cables should be equipped with shielded connectors. The backshells of these connectors must completely surround the cable shield.
