Installing New Wire

If you are installing the repeater where no wiring is present, or if existing wiring does not meet the above specifications, install new wiring. The new wiring should conform to national and local electrical wiring code requirements and meet the above specifications. When installing wire, it is a good idea to install extra pairs of wire for future expansion.

If you are unfamiliar with wiring installation or the applicable local electrical wiring code or the 100Base-TX specification, you should have a professional, licensed (if applicable) installer perform the installation.

Straight-through twisted-pair cable is typically used to connect a repeater to a server or workstation. In a straight-through connection, Pin 1 at the repeater connects to Pin 1 at the server, Pin 2 at the repeater connects to Pin 2 at the server, and so on. Figure 2-1 shows the locations of pins on a standard RJ-45 plug on a twisted-pair cable.
