About 90 locations within the School are wired with thin-wire ethernet outlets. Each outlet is on a segment of ethernet--there are about 30 segments in the School all connected through ``multiport transceivers'' to a thick-wire cable, and thence to a fibre optic line with the campus-wide network. A segment is a single line of RG-58A/U 50 ohm coaxial cable up to 185 metres long, and terminated with a 50 ohm resistor at one end, and a ``multiport transceiver'' at the other. Wall plates allow you to connect devices to a segment. There are two types of wall plates: those in the middle of a segment, which have two sockets, and those at the end of a segment, which have one socket.
The important wiring rules for the ethernet are as follows:
