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.

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.

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):

  1. Place an antistatic bag or antistatic mat on a flat, stable surface to receive the QSFP28 transceiver. Have a rubber safety cap ready for the QSFP28 transceiver and the cable.
  2. 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.
  3. Label the cable connected to the QSFP28 transceiver so that you can later reconnect it to the correct QSFP28 transceiver.
  4. Disconnect the cable from the transceiver. Immediately cover the transceiver and the end of the cable with a rubber safety cap.Caution

    Do not leave a fiber-optic transceiver uncovered except when inserting or removing a cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.

  5. 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.Caution

    Do not bend the 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.

  6. Pull the ejector tab straight back. The locking pins on the transceiver automatically release the transceiver.
  7. Place the transceiver on the antistatic mat or in the antistatic bag.
  8. Place the dust cover over the empty port or install the replacement transceiver.
