Installing a QSFP28 Transceiver

108
Disconnect the cable from the transceiver. Immediately cover the transceiver and the
4.
end of the cable with a rubber safety cap.
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 it from dislodging or
5.
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: 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.
Pull the transceiver's rubber handle straight back. The locking pins on the transceiver
6.
automatically releases the transceiver. Place the transceiver on the antistatic mat or
in the electrostatic bag.

Verify that a rubber safety cap covers the QSFP28 transceiver.
