Laying the Ethernet Network
Basic precautions for the installation of Ethernet networks are provided below.
• When you install an Ethernet network, take sufficient safety precautions and follow the standards and
specifications. (Refer to JIS X5252 or to electrical facility technical references.)
An expert who is well trained in safety measures, standards and specifications should be asked to
perform the installation.
• Do not install Ethernet network equipment near sources of noise.
If the network must be installed in an area subject to noise, take steps to address the noise, such as
placing equipment in metal cases.
• Check the following items on the communications cables that are used in the network.
a) Are there any breaks?
b) Are there any shorts?
c) Are there any connector problems?
• When you connect the cable to the communications connectors on devices, firmly insert the commu-
nications cable connector until it locks into place.
• Do not lay the communications cables together with high-voltage lines.
• Do not lay the communications cable near devices that generate noise.
• Do not lay the communications cables in locations subject to high temperatures or high humidity.
• Do not lay the communications cables in locations subject to excessive dirt and dust or to oil mist or
other contaminants.
• There are limitations on the bending radius of communications cables. Check the specifications of
the communications cable for the bending radius.
