Replacing transceiver modules
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 router is operating.
CAUTION:
•
Do not touch the golden plating on a transceiver module.
•
Make sure the transceiver modules at the two ends of an optical fiber are the same model.
To replace a transceiver module and optical fiber:
1. Wear an ESD wrist strap. Make sure the wrist strap makes good skin contact and is reliably
grounded.
2. Remove the optical fibers from the transceiver module.
