907-EIBS (10 Mbps Ethernet Switch Card)

Card P/N
Config. Dwg.
Diagnostics:
The three-port, 10 Mbps Ethernet expansion card is shown below in Figure 5-1. All three RJ-45 jacks support
10/100 Mbps Ethernet linking and are connected to a switching hub chip. A fourth Ethernet port from the hub
chip is used to transmit and receive data through one of the six backplane data ports on the Model 907
motherboard. Local traffic between on-board RJ-45 ports is supported and is not transmitted through the
optical link.
The remote to console throughput is limited to 10 Mbps, so any aggregate traffic beyond this will cause the
Ethernet switch to generate flow control packets. If multiple, separate Ethernet links are required, for example
as dedicated links for two different sensors, multiple 907-EIBS expansion cards may be stacked together.
Each RJ-45 jack has built-in magnetics for galvanic isolation.
Configure switch SW1 to set the backplane data port used by the 907-EIBS card. All ports (1-6) are available.
The default setting is data port #1.
