B-4 Installation and Operation
Connecting the LAN
Use either a straight cable or a cross cable for the LAN connection.
Use a cross cable when connecting to a port that does not implement the
crossover function internally. Otherwise, use a straight cable.
Hubs usually implement the crossover function internally, while NICs and other
devices do not.
