Redundant twisted-pair et COM2 port
adapter
The Redundant TP Et COM2 Port card (GE Item No. 520-0218LF) 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 data rate on the LAN port is
independently detected and set to either 10 Mbps or 100 Mbps. The data rate on the
WAN port is set to 100 Mbps. The LAN port can be configured to use network
parameters provided by a DHCP server when the Dynamic Address option is selected
for the Network Interface (NET1 when this card is installed in slot 11 and NET2 when
installed in slot 12). The WAN port does not support the Dynamic Address option and
should not be selected for the Network Interface (NET2 when this card is installed in
slot 11 and NET3 when installed in slot 12).
• An RS-232 DCE connection through a DB-9 connector. The Redundant TP Et
COM2 Port card is normally installed in the NET1 slot (slot 11) on the D400. The
Redundant TP Et COM2 Port card can also be installed in the NET2 slot (slot
12), but this configuration is only supported with v5.01 (and later) firmware. Refer to
section: “Parallel Redundancy Protocol (PRP)” on page 131.
NOTE
Use of the Redundant TP Et COM2 Port card requires the installation of the dual
redundant Ethernet D400 CPU option, which includes the PC/104-Plus Ethernet Module
and cables (GE part number 580-3410, 977-0544, and 977-0549). The COM2 Port requires
an external modem to provide dial-up functionality.
See “Network connections” on page 65 and “Modem connections” on page 67 for typical
cable connections.
