Removing a QSFP28 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.
After you insert a transceiver or after you change the media-type configuration, wait for 6 seconds for the interface to display operational commands.
We recommend that you use only optical transceivers and optical connectors purchased from Juniper Networks with your Juniper Networks device.
Before you begin to remove a transceiver from a device, ensure that you have taken the necessary precautions for safe handling of lasers (see Laser and LED Safety Guidelines and Warnings).
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
To remove a QSFP28 transceiver (see Figure 1):
- Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the QSFP28 transceiver. Have ready a rubber safety cap for the QSFP28 transceiver and the cable.
- Wrap and fasten one end of an ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the switch.
- Label the cable connected to the QSFP28 transceiver so that you can later reconnect it to the correct QSFP28 transceiver.
- Disconnect the cable from the transceiver. Immediately
cover the transceiver and the end of the cable with a rubber safety
Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.
- If there is a cable management system, arrange the cable
in the cable management system to prevent it from dislodging or developing
stress points. Secure the cable so that it does not support its own
weight as it hangs to the floor. Place excess cable out of the way
in a neatly coiled loop in the cable management system. Placing fasteners
on the loop helps to maintain its shape.
Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.
- Pull the transceiver’s rubber handle straight back. The locking pins on the transceiver automatically release the transceiver.
- Place the transceiver on the antistatic mat or in the electrostatic bag.
- Place the dust cover over the empty port or install the replacement transceiver.
