Orient the transceiver over the port in the MIC, MPC, or router so that the QSFP28
3.
connector faces the appropriate direction.
Slide the transceiver into the slot until the locking pins lock in place. If there is
4.
resistance, remove the transciever and flip it so that the connector faces the other
direction.
Remove the rubber safety cap from the transceiver and the end of the cable, and
5.
insert the cable into the transceiver.
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.
Arrange the cable in the cable management system to prevent the cable from
6.
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.
CAUTION: Avoid bending fiber-optic cable beyond its minimum bend
radius. An arc smaller than a few inches in diameter can damage the cable
and cause problems that are difficult to diagnose.
Verify that the status LEDs on the MPC, MIC, or router faceplate indicate that the
7.
QSFP28 transciever is functioning correctly. For more information about the MPC,
MIC, or router LEDs, see the
