Replacing a transceiver module

WARNING!

Do not stare into any open apertures of operating transceiver modules or optical fiber connectors. The laser light emitted from these apertures might hurt your eyes.

CAUTION:

· During the installation or removal process, be careful not to touch the golden plating on the transceiver module.

· In case of limited space, you can use the provided tweezers and other tools to remove a transceiver module or optical fiber.

Make sure the transceiver modules at the two ends of an optical fiber are the same model.

Replacing an XFP/QSFP+/SFP+/SFP/QSFP28 transceiver module

The replacement procedure is similar for XFP, QSFP+, QSFP28, SFP+, and SFP transceiver modules. The following uses an SFP+ transceiver module for illustration.

To replace an SFP+ transceiver module:

1. Wear an ESD wrist strap and make sure it makes good skin contact and is correctly grounded.

For more information, see "Attaching an ESD wrist strap."

2. Remove the optical fibers on the module.

There is a latching mechanism between a fiber connector and transceiver module port to prevent connector disengagement. Release the latching mechanism before removing the optical fiber. To avoid damages, do not use excessive force.

3. Pivot the clasp down to the horizontal position.

4. Grasp the clasp on the module and carefully pull the module out of the slot.

If you use force at an angle, you can hardly pull the transceiver module out and the transceiver module or fiber port might be damaged. If you forcibly pull out of the transceiver module without pivoting the bail latch down, the triangular pin of the transceiver module and the fiber port might be damaged.

To avoid damaging the bail latch, use event force to pull the transceiver module out.
