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.
