3. Orient the transceiver in front of the port so that the QSFP28 connector faces the appropriate
direction.

4. Slide the transceiver into the slot until the locking pins lock in place. If there is resistance, remove the
transceiver and flip it so that the connector faces the other direction.
5. 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 fiber-optic transceiver or into the ends of
fiber-optic cables. Fiber-optic transceivers and fiber-optic cable connected to a transceiver
emit laser light that can damage your eyes.
CAUTION: Do not leave a fiber-optic transceiver uncovered except when inserting or
removing cable. The safety cap keeps the port clean and prevents accidental exposure
to laser light.
6. 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 floor. 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 fiber-optic cable hang free from the connector. Do not allow
fastened loops of cable to dangle, which stresses the cable at the fastening point.
