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.
5. Arrange the cable in the cable management system to prevent it from dislodging or developing stress
points. Secure the cable so that it is not supporting 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: 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.
6. Pull the transceiver's rubber handle straight back. The locking pins on the transceiver automatically
release. Place the transceiver on the antistatic mat or in the electrostatic bag.
Install a QSFP28 or QSFP56-DD Transceiver
To install a replacement QSFP28 or QSFP56-DD transceiver:
1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to
one of the ESD points on the chassis.
2. Verify that a rubber safety cap covers the transceiver, installing one if necessary.
3. Orient the transceiver over the port so that the transceiver 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.
