Ethernet cabling is like U.S. telephone cables, except that it has eight
conductors. Some hubs have one input that can accept either a straight-through
or crossover cable, depending on a switch position. In this case, you must ensure
that the switch position and cable type agree.
Refer to Ethernet Cable Configuration (page 145) for a diagram of how to
configure Ethernet cable.

6.3.3 Ethernet Performance
High Ethernet traffic may impact MCM performance, consider one of these
options:
 Use managed switches to reduce traffic coming to module port
 Use CIPconnect for these applications and disconnect the module Ethernet
port from the network
