The 28-Gbps quad small form-factor pluggable (QSFP28) transceivers for Juniper Network devices are
hot-insertable and hot-removable components. Removing a QSFP28 transceiver does not interrupt the
device functioning, but the removed QSFP28 transceiver no longer receives or transmits data.

To remove a QSFP28 transceiver (see
1. Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the transceiver. Have
ready a rubber safety cap for the QSFP28 transceiver and the cable.
2. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other
end of the strap to the ESD point on the chassis.
3. Label the cable connected to the QSFP28 transceiver so that you can later reconnect the cable to
the correct transceiver.
4. Disconnect the cable from the transceiver. Immediately cover the transceiver and the end of the
cable connector with a rubber safety cap.
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.
5. Arrange the cable in the cable management system to prevent it 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.
