Huawei S2700 - Replacing a Card

Step 5 Take out the new optical module from the package. Ensure that the optical module is correctly
oriented and gently push it into the optical port until you hear a click.
NOTE
The new optical module must have the same optical parameters as the remote optical module connected
to it.
Step 6 Identify the optical fibers to be connected to the optical module. Remove the dust caps from
the optical fibers and insert the optical fibers to the bores of the optical module.

Follow-up Procedure
If the new optical module does not work, unplug the optical fibers and clean their connectors
in one direction with an alcohol swab. Then, re-connect them. If this fails to resolve the issue,
contact the equipment supplier or local maintenance personnel for technical support.
