Remove a Transceiver

Before you remove a transceiver from a device, ensure that you have taken the necessary precautions
for the safe handling of lasers (see
Ensure that you have the following parts and tools available:
• An antistatic bag or an antistatic mat
• Rubber safety caps to cover the transceiver and fiber-optic cable connector
• A dust cover to cover the port or a replacement transceiver
The transceivers for Juniper Networks devices are hot-removable and hot-insertable field-replaceable
units (FRUs): You can remove and replace them without powering off the device or disrupting device
functions.
NOTE: After you remove a transceiver or when you change the media-type configuration, wait
for 6 seconds for the interface to display the operational commands.
Figure 57 on page 148 shows how to remove a QSFP+ transceiver. The procedure is the same for all
types of transceivers except the QSFP28 and CFP transceivers.
To remove a transceiver from a device:
1. Place the antistatic bag or antistatic mat on a flat, stable surface.
2. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end
of the strap to the ESD point on the switch.
3. Label the cable connected to the transceiver so that you can reconnect it correctly.
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 cables connected to transceivers
emit laser light that can damage your eyes.
