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.
• If you are not to insert a transceiver module into a fiber port, insert the dust plug provided with the
module into the port to prevent foreign object intrusion.
NOTE:
In case of limited space, you can use tweezers or other tools to remove a transceiver module or
optical fiber.
Replacing a 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.
To remove optical fibers with an LC connector, press the clip on the connector to pull the LC

connector out of the port, as shown in Figure8-9.
To remove an optical fiber with an MPO connector, hold the front end of the MPO connector

and then pull it out of the port, as shown in Figure8-10.
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 the dust plug into the removed module, and put the module into its packaging bag.
6. Install a new module. For the installation procedure, see "Installing a transceiver module and
connecting optical fibers."
