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. (Hubs usually
implement the crossover function internally while NICs and other devices do not.)
Switch Settings
Set switches according to Table A-2.
