Juniper EX2300 Series Hardware Manual page 161

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 86 on page 154 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
for at least 10 seconds after removing the transceiver from the port before installing a new
transceiver.
5. Using both hands, carefully place the transceiver in the empty port. The connectors must face the
chassis.
