Installing A Qsfp28 Transceiver - Juniper PTX5000 Hardware Manual

To remove a QSFP28 transceiver (see
1. Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the QSFP28
transceiver. Have ready a rubber safety cap for the QSFP28 transceiver and the cable.
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to
one of the ESD points on the chassis.
3. Label the cable connected to the QSFP28 transceiver so that you can later reconnect it to the correct
QSFP28 transceiver.
4. Disconnect the cable from the QSFP28 transceiver. Immediately cover the transceiver and the end of
the cable 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 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.

Installing a QSFP28 Transceiver

To install a replacement QSFP28:
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 QSFP28 transceiver, installing one if necessary.
