Chapter 2: Pre-Installation Planning
Network Operating Environment
Use access points which are allowed to be installed directly in the pig area. The Ethernet switch and
router are not built for harsh environments. It is strongly advised to install them in a clean room or office. If
this is not possible, consider using a NEMA 4X protection box to install them in. Request a CSA/UL certi-
fied box from your supplier.
Wireless Network Design
A lot of environmental parameters could affect the wireless communication: the barn configuration, the
wall material, the building faraday cage effect, the antenna pattern transmission, or the number of units
using a given network.
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
Lightning can destroy an EDGE System Ethernet port if not protected when routing a
connection from building to building.
NOTICE
AP\Cumberland recommends the use of an underground trench to link two barns.
Ethernet Infrastructure Advice
• Plan for the future expansion.
• Use a 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.
Guidelines for Installation Location
Requirements for the Mounting Structure
Fix the enclosures into the supporting structure behind a drywall. If this is not possible, consider the addi-
tion of a wood frame on which the enclosure could be screwed.
