6.2 Installing Optical Modules
NOTICE
Huawei-certified optical modules need to be used. This is because the
reliability of non-Huawei-certified optical modules cannot be ensured,
and using such modules may affect service stability.
Wear ESD wrist straps or ESD gloves before installing optical modules.
Install dust-proof caps on optical ports without optical modules.
Ensure that optical modules are not reversely installed. If an optical
module cannot be completely inserted into an optical port, do not force
it into the port. Turn the optical module over and try again.
Insert the optical module fully into the optical port.

properly.
