ST Port
The ST port on the 3C900B-FL NIC provides a 10 Mbps 
fiber-based connection only.
The following table shows the cable requirements and 
maximum network cable lengths for the ST port.
To connect the ST port:
1 Remove the protective covers from the NIC’s 
ST connector.
2 Connect the network cable to the ST connector on 
the NIC.
The cable that you use for the 3C900B-FL NIC consists of 
two individual cables. You can insert either cable into the 
transmit (10) and receive (RX) connectors on the NIC.
