9-8-3 Network Installation
Basic Installation Precautions
• Take the greatest care when installing the Ethernet System, being sure to
follow ISO 802-3 specifications. You must obtain a copy of these specifi-
cations and be sure you understand them before attempting to install an
Ethernet System. Unless you are already experienced in installing com-
munications systems, we strongly recommend that you employ a profes-
sional to install your system.
• Do not install Ethernet equipment near sources of noise. If noise-prone
environments are unavoidable, be sure to take adequate measures
against noise interference, such as installing network components in
grounded metal cases, using optical links in the system, etc.
