CS1W-ETN11, CJ1W-ETN11 (10Base-T) Precautions
Precautions on Laying Twisted-pair Cable
Basic Precautions
Press the cable connector in firmly until it locks into place at both the hub and the Ethernet Unit.
After laying the twisted-pair cable, check the connection with a 10Base-T cable tester.
Environment Precautions
The twisted-pair cable for 10Base-T is not shielded, and the hub is designed for use in OA environments.
In environments subject to noise, we recommend the use of 10Base-5 Ethernet.
Do not lay the twisted-pair cable together with high-voltage lines.
Do not lay the twisted-pair cable near devices that generate noise.
Do not lay the twisted-pair cable in locations subject to high temperatures or high humidity.
Do not lay the twisted-pair cable in locations subject to excessive dirt and dust or to oil mist or other con-
taminants.
Hub Installation Environment Precautions
Do not install the hub near devices that generate noise.
Do not install the hub in locations subject to high temperatures or high humidity.
Do not install the hub in locations subject to excessive dirt and dust or to oil mist or other contaminants.
