Juniper EX2300 Series Hardware Guide

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 prevents 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 to 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.
