Installation

3. Attach the fiber optic data cables to the fiber optic ports, as shown

in Figure 20.

Figure 20 Attaching a Fiber Optic Cable

When you attach a fiber optic cable, be sure to observe the

following guidelines:

❑ Be sure that the cable connector is firmly locked into place in

the port.

❑ A dual SC port consists of two separate connectors, as shown

in Figure 21. Each connects to a separate fiber strand. One is

for receiving packets and the other is for transmitting packets.

When you connect a fiber optic cable to a dual 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.
