Juniper ACX7100-32C Hardware Manual page 106

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.
Figure 44 on page 100 shows how to install a QSFP+ transceiver. The procedure is the same for all types
of transceivers except the QSFP28 and CFP transceivers.
To install a transceiver:
CAUTION: To prevent electrostatic discharge (ESD) damage to the transceiver, do not
touch the connector pins at the end of the transceiver.
1. 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.
2. Remove the transceiver from its bag.
3. Check to see whether the transceiver is covered with a rubber safety cap. If it is not, cover the
transceiver with a rubber safety cap.
LASER WARNING: Do not leave a fiber-optic transceiver uncovered except when
inserting or removing a cable. The rubber safety cap keeps the port clean and prevents
accidental exposure to laser light.
4. If the port in which you want to install the transceiver is covered with a dust cover, remove the dust
cover and save it in case you need to cover the port later. If you are hot-swapping a transceiver, wait
