7. Remove the rubber safety cap from the transceiver and the end of the cable, and insert the cable into
the transceiver.
LASER WARNING: Do not look directly into a ber-opc transceiver or into the ends
of ber-opc cables. Fiber-opc transceivers and ber-opc cable connected to a
transceiver emit laser light that can damage your eyes.
CAUTION: Do not leave a ber-opc transceiver uncovered except when inserng or
removing cable. The safety cap keeps the port clean and protects your eyes from
accidental exposure to laser light.
8. If there is a cable management system, arrange the cable in the cable management system to prevent
the cable from dislodging or developing stress points. Secure the cable so that it does not support its
own weight as it hangs toward the oor. Place excess cable out of the way in a neatly coiled loop in
the cable management system. Placing fasteners on the loop helps to maintain its shape.
CAUTION: Do not let ber-opc cable hang free from the connector. Do not allow
fastened loops of cable to dangle, which stresses the cable at the fastening point.
CAUTION: Avoid bending ber-opc cable beyond its minimum bend radius. An arc
smaller than a few inches in diameter can damage the cable and cause problems that
are dicult to diagnose.
NOTE: When you install SFP-DD transceivers, push it hard unl you hear a click sound. Use a
long nose plier to pull the SFP-DD transceiver connected on the top and boom rows of the
chassis where the pull tabs face each other.
NOTE: Make sure to use a dust cap to cover ports that are unused.
