Installation and Operation A-5
LAN Installation For 10BaseT installation, either a straight cable or a cross-cable may be
required. Use a cross-cable when connecting to a port that does not
implement the crossover function internally. Otherwise, use a straight cable.
Note
Hubs usually implement the crossover function internally while NICs and other
devices do not.
