Make sure the unit is installed in a location that is easily accessible to an AC power
outlet or power strip, and where convection cooling is not inhibited.
3.2 Calculating Segment Distances
The media distance considerations are quite different for full-duplex and for
half-duplex (standard Fast Ethernet) installations. Each of these situations are covered
below in a separate section.
3.2.1 Segment Distances, Full-duplex
Full-duplex ports, such as are found in switching hubs and some NICs, can
receive and transmit signals simultaneously and do not experience collisions accordingly.
There may be only two nodes present on a full-duplex segment. Media distance rules are
not the same as for standard (half-duplex) Fast Ethernet because collision distance
