11.2 Replacing an Optical Module

Context
Never look directly into an optical module or the ends of optical fibers. Optical modules and
connected fibers emit laser radiation that will cause eye damage.
Use optical modules certified for Huawei switches. Using other optical modules may affect
service stability and Huawei can accept no liability for the outcome.
Ensure that the new optical module has the same center wavelength and complies with the
same standards as the old one.
Optical modules are electrostatic-sensitive components. Take ESD protection measures when
replacing optical modules.
