Precautions for receptacle contamination

Only optical modules matching Huawei products can be used. These optical modules are strictly tested
by Huawei. If non-matching optical modules are used, device requirements may fail to be met, and
services may fail to run properly. To replace optical modules, see Parts Replacement-Replacing an
Optical Module.
When installing an optical module, force it into position. If a click is heard or a slight
tremor is felt, it indicates that the latch is secured. When the latch is not secured, the
connecting finger is not properly connected to the board, and the link may become Up.
In the rare event where the optical modulecollides with another object or is made to
tremor, the optical module will be loosened or the optical signals will be temporarily cut
off.
When inserting the optical module, make sure that the tab is closed. (At this time, the
latch locks the optical module.) After the optical module is inserted, try pulling it out to
see whether it is installed properly. If the optical module cannot be pulled out, it is
secured.
Clean tissues must be prepared for deployment on site. You need to clean the optical
connector before inserting it in the receptacle. This protects the receptacle against the
contamination.
Use at least three cleaning tissues. Wipe the end of an optical connector horizontally in one direction,
and then move the connector end to the unused part of the cleaning tissue to continue. Generally, one
cleaning tissue is used for cleaning an optical connector.
To prevent contamination, the optical module should be covered with either a dust cap or
an optical connector.
