Connecting Cables to Equipment
• Ensure that the fiber optic cable has proper cable strain relief so that the cable is not
stressed. While this may not cause a failure during installation, it may lead to potential
reliability problems later.
• Also verify that the cable is not bent over the minimum bend radius.
• Remove the dust caps from the cable connector and the equipment and clean the
connectors using pure alcohol and a lint free towel as described in the cleaning section
above. Dry with dry compressed air.
• The ERAU and the CDU have LED indicators to show if the optical link is correctly
operating. See the Table 6-1 below for the LED indicators for the CDU and ERAU.

• To avoid confusion and help in system debugging, it is often necessary to provide cable
markers on the cable ends to ensure that the correct cable is plugged into the correct
equipment plug. Cable marker kits for field marking are available from Panduit, part
number PLD-1 and Anixter, part number A0000783865.
