3-6-1 Ethernet Network Installation
When installing an Ethernet network, be sure to take all appropriate safety mea-
sures and to follow the applicable standards (ISO 8802-3). You must obtain a
copy of these specifications and be sure you understand them before attempting
to install an Ethernet System. Unless you are already experienced in installing
communications systems, we strongly recommend that you employ a profes-
sional to install your system.
For information regarding basic installation precautions, equipment, recom-
mended products, and installation examples, refer to Appendix A Network
Installation.

3-6-3 Connecting the Transceiver Cable
Caution
Turn OFF the PC’s power supply before connecting or disconnecting transceiv-
er cable.
1, 2, 3...
1. Prepare a coaxial cable.
2. Connect the transceivers to the coaxial cable.
•
Mark the coaxial cable at intervals of 2.5 meters. Then connect the trans-
ceivers at those marks.
•
The transceiver connection method depends on the type of transceiver, so
refer to the transceiver operation manual.
3. Prepare the transceiver cable, and then connect it to the transceivers.
For more details regarding these steps, refer to Appendix A Network Installation.
The cable preparation should be performed by an experienced professional.
