Replacing a transceiver module
WARNING!
Disconnected optical fibers or transceiver modules might emit invisible laser light. Do not stare into
beams or view directly with optical instruments when the switch is operating.
CAUTION:
•
Do not touch the golden plating on a transceiver module during the replacement process.
•
Make sure the new transceiver module is the same model as the peer transceiver module at the
other end of the optical fiber.
•
In case of limited space, you can use the provided tweezers and other tools to remove a
transceiver module or optical fiber.
Replacing an XFP/QSFP+/QSFP28/SFP28/SFP+/SFP
transceiver module
The replacement procedure is similar for XFP, QSFP+, QSFP28, SFP28, 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 from the module.
There is a latching mechanism between a fiber connector and transceiver module bore to
prevent connector disengagement. Release the latching mechanism before removing the
optical fiber. To avoid damages, do not use excessive force.
3. Pivot the bail latch down to the horizontal position.
4. Hold the bail latch to pull the module out of the slot. Make sure you apply force in the direction
parallel to the ground. To avoid damaging the bail latch, do not use excessive force.
If you apply force at an angle when pulling the module out, you can hardly pull the module out
and the module or fiber port might be damaged.
5. Insert dust plugs into the removed module, and put the module into its packaging bag.
6. Install a new module. For the installation procedure, see "Installing an
XFP/QSFP+/QSFP28/SFP28/SFP+/SFP module."
