4-Port twisted-pair ethernet switch
The 4-Port Twisted-Pair Ethernet Switch (GE Item No. 520-0213LF) is a 10/100BaseT
network switch that plugs into the NET1 slot (slot 11) on the D400. It provides local area
network connections for up to five Ethernet connections: four RJ-45 connectors on the
rear panel and one RJ-45 connector on the front panel. The connector used is four RJ-45
connectors ganged together. The data rate is automatically detected and set to either 10
Mbps or 100 Mbps.
A second Ethernet switch can be installed in the NET2 slot (slot 12). If two Ethernet switches
are installed in the NET slots, the D400 may be used in a dual-IP redundancy mode. That is,
each switch can be configured with a different IP address to provide a backup network
connection if the primary channel fails. Use of this card in slot 12 requires installation of the
dual redundant Ethernet CPU option which includes the PC/104-Plus 10/100BasetT
Ethernet Module and cable (GE item 580-3410 and 977-0544).
See “Network connections” on page 61 for typical cable connections.
TIP
If additional ports are required, two Ethernet switches can be connected to each other with
an Ethernet cable. This will increase the number of available 10/100BaseT ports to 6.
Configuration options
There are no selectable options on the 4-Port TP Ethernet card.
