Ethernet port protectors
The controllers are provided with two Ethernet port protectors that can be used as blanks for the Ethernet ports on the top of the
controller.
INFO
DEIF recommends that the Ethernet port protectors remain installed in the top Ethernet ports (connection 1 and 2) when
these are not in use. The Ethernet port protectors protect the ports from dust and foreign objects.
Cable bend radius
Bends in the Ethernet cables must not be tighter than the minimum bend radius specified by the cable manufacturers.
INFO
DEIF recommends that you always follow the cable manufacturer's bend radius requirements. As a guideline, Ethernet
cables may require a minimum bend radius of 40 mm (1.6 in).
Redundancy and routing
Each controller can be connected so that there is redundant communication (that is, two independent Ethernet connections) to other
controllers. If you need redundant communication, you should route the Ethernet cables for redundancy. A single failure (for
example, damage to a cable rack) should not damage both of the Ethernet connections to the other controllers.
MORE INFORMATION
See Wiring the communication, DEIF Ethernet network communication, Topology examples for more information.
Wiring the Ethernet cable
The controllers and display units use any type of Ethernet cable, provided it meets or exceeds SF/UTP CAT5e specification.
