❑
SC ports consist of two separate connectors, as shown in Figure 10.
Each connects to a separate fiber strand. One is for receiving data and
the other is for transmitting data. When connecting a fiber optic cable
to a SC port, be sure that the receiver fiber connector is connected to
the transmitter connector on the remote end-node, and the
transmitter fiber connector is connected to the receiver connector on
the remote node.

Connect the twisted pair cable to the 10Base-T/100Base-TX port.
When connecting a twisted pair cable to a port, observe the following
guidelines:
❑
An RJ-45 connector should fit snugly into the port on the converter.
The tab on the connector should lock the connector into place.
❑
You should check to be sure that you are using the appropriate type of
twisted pair cabling. Refer to Table 3 on page 16for twisted pair cable
specifications.
❑
Since the twisted pair port, when operating in Auto-Negotiation, is
Auto MDI/MDI-X, you can use either a straight-through or crossover
twisted pair cable to connect any type of network device to a port on
the converter. If you disable Auto-Negotiation on the port, the port
default to MDI-X.
9.
Power ON the end-nodes.
10. Verify that the LNK LEDs for both the fiber optic port and the twisted
pair port are green. If either LED is OFF, refer to “Troubleshooting” on
page 31 for instructions.
