Ethernet Switches
The 3000/06 Atom Node Processors and 3200/3201 Node/Chassis Processor require industrial-quality 1-
GB TX Ethernet Switches. The 3000/01 Chassis Processors, the 3000/02-004 Modbus TCP Cards, and
Distributed I/O Cards require industrial-quality 100-Base TX Ethernet Switches. Ethernet switches must
not re-compute the packet CRCs. While the Host Ethernet switches can be managed, I/O Ethernet
switches connected to the RTP3000 TAS shall be unmanaged. RTP recommends STP Category 5 (EIA
568B, Cat 5), shielded Ethernet cables with four twisted-pair wires and RJ-45 tips. These cables are
limited to a maximum length of 328 feet (100 meters).
