CAUTION: The Juniper Networks Technical Assistance Center (JTAC) provides
complete support for Juniper-supplied optical modules and cables. However, JTAC does
not provide support for third-party optical modules and cables that are not qualified or
supplied by Juniper Networks. If you face a problem running a Juniper device that uses
third-party optical modules or cables, JTAC may help you diagnose host-related issues if
the observed issue is not, in the opinion of JTAC, related to the use of the third-party
optical modules or cables. Your JTAC engineer will likely request that you check the
third-party optical module or cable and, if required, replace it with an equivalent
Juniper-qualified component.
Use of third-party optical modules with high-power consumption (for example,
coherent ZR or ZR+) can potentially cause thermal damage to or reduce the lifespan of
the host equipment. Any damage to the host equipment due to the use of third-party
optical modules or cables is the users' responsibility. Juniper Networks will accept no
liability for any damage caused due to such use.
Before you begin to install a transceiver in a device, ensure that you have taken the necessary
precautions for safe handling of lasers (see
116).
Ensure that you have a rubber safety cap available to cover the transceiver.
To install a replacement QSFP28 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 device.
2. Verify that a rubber safety cap covers the QSFP28 transceiver, installing one if necessary.
3. Orient the transceiver over the port so that the transceiver connector faces the appropriate
direction.
4. Slide the QSFP28 transceiver into the port until the locking pins lock in place. If there is resistance,
remove the transceiver and flip it so that the connector faces the other direction and slide it into the
slot. Ensure that the transceiver is seated snugly in the port.
5. Remove the rubber safety cap from the transceiver and the end of the cable connector, and insert
the cable into the transceiver.
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.
