3.10 Redundant Twisted-Pair Ethernet + COM2 Port Adapter
The Redundant TP Ethernet + COM2 Port card (GE Part No. 520-0218) provides two local
area network connections with unique MAC addresses through Ethernet RJ-45
connectors. The LAN input routes to a three-port Ethernet switch and the WAN input
routes to the PC/104-Plus Ethernet Module. The Ethernet switch can support a dual-
redundancy network option on the D400. The card also provides an RS-232 DCE
connection through a DB-9 connector. The Redundant TP Ethernet + COM2 Port card can
only be installed in the NET1 slot (slot 11) on the D400.
Note: Use of the Redundant TP Ethernet + COM2 Port card requires the installation of the
Dual Redundant Ethernet D400 CPU option, which includes the PC/104-Plus 10/100BaseT
Ethernet module (GE Part No. 580-2717). The COM2 Port requires an external modem to
provide dial-up functionality.
See sections “4.7 Network Connections” and “4.8 Modem Connections” for typical cable
connections.
