7. Place the transceiver in the antistatic bag or on the antistatic mat placed on a flat, stable surface.

Installing a 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 the device
functions.
NOTE: After you insert a transceiver or after you change the media-type configuration, wait for
6 seconds for the interface to display operational commands.
NOTE: We recommend that you use only optical transceivers and optical connectors purchased
from Juniper Networks with your Juniper Networks device.
CAUTION: If you face a problem running a Juniper Networks device that uses a third-party
optic or cable, the Juniper Networks Technical Assistance Center (JTAC) can help you
diagnose the source of the problem. Your JTAC engineer might recommend that you
check the third-party optic or cable and potentially replace it with an equivalent Juniper
Networks optic or cable that is qualified for the device.
Before you begin to install a transceiver in a device, ensure that you have taken the necessary precautions
for safe handling of lasers (see “Laser and LED Safety Guidelines and Warnings” on page 220 ).
Ensure that you have a rubber safety cap available to cover the transceiver.
Figure 71 on page 168 shows how to install a QSFP+ transceiver. The procedure is the same for all types
of transceivers except the QSFP28 and CFP transceivers.
