Ethernet Ports
Ethernet Port Protection
AP\Cumberland recommends the use of another Ethernet protection step when the Ethernet cable has to
go from one barn to another using the Ethernet switches. This recommendation is applicable regardless
of the way it is used to link both barns.
Ensure that the Ethernet protection ports can accept the use of CAT5 Ethernet speed at a minimum.
NOTE: Some Ethernet protection ports can alter the Ethernet signals because it is too capacitive.
WARNING
By not protecting the Ethernet ports when they have to go outside, a thunderstorm
could destroy the Ethernet link of the EDGE System.
NOTICE
AP\Cumberland recommends the use of an underground trench to link two barns.
Ethernet Infrastructure Advice
• Plan for the future.
• Use CAT5 Ethernet cable.
• Use cable management (Adding ladder rack, rack-based cable management).
• Avoid running unshielded twisted Ethernet cable (UTP) in parallel with high voltage cables. The
magnetic field is disruptive and the communication becomes noisy and garbled.
• Avoid running Ethernet cables near electrically noisy devices like a frequency drive, Light Dimmer,
motor load, etc.
• The typical distance limitation for UTP cabling with typical Ethernet is 100 meters (328 ft.).
• Follow all laws and local codes for the Ethernet cabling (GR-1089, International
Telecommunications
• Union standards K.20, K.21, K.44, and K.45).
• Test each Ethernet cable and the telecommunication components when the telecommunication
infrastructure installation is finished
Recommended Ethernet Cable
For a majority of installation inside the barn, a minimum unshielded twisted pair (UTP) Cat5 Ethernet
cable or higher category could be selected on the market by using similar ratings.
