Note Connectors on the fiber-optic cables must be free of dust, oil, or other contaminants. Before
connecting the cable to the line card, carefully clean the fiber-optic connectors using an
alcohol wipe or other suitable cleanser. Refer to the “Cleaning Fiber-Optic Connectors”
section on page 55 for more information.
To install a cable, follow these steps:
Step 1 Remove the connector dust cover if one is present.
Step 2 Align the connector end of the cable to the appropriate port. Observe the receive (RX) and transmit (TX)
cable relationship on the cables, as shown in Figure 41 and Figure 42.
Step 3 Attach fiber cable between the port in the line card and the device to which the line card is connected.
Step 4 Insert the fiber cable connector until it clicks and locks into place.
Step 5 Repeat these steps until all cabling is complete.
