4. If the port in which you want to install the transceiver is covered with a dust cover, remove the dust
cover and save it in case you need to cover the port later. If you are hot-swapping a transceiver, wait
for at least 10 seconds aer removing the transceiver from the port before installing a new
transceiver.
5. Using both hands, carefully place the transceiver in the empty port. The connectors must face the
chassis.
CAUTION: Before you slide the transceiver into the port, ensure that the transceiver is
aligned correctly. Misalignment might cause the pins to bend, making the transceiver
unusable.
6. Slide the transceiver in gently unl it is fully seated. If you are installing a CFP transceiver, hand
ghten the capve screws on the transceiver.
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.
