When installing an optical module, insert it into position. If you hear a click or feel a slight
shake, it indicates that the latch boss is secured.
If the latch boss is not secured, the gold finger of the optical module is not in good contact
with the connector on the board. In this case, the link may be connected but optical signals
will be cut off or the optical module will be loosened when the optical module is shook or
crashed.
Figure 5-95 shows the release handle on an optical module when it is open and closed.
When inserting the optical module, make sure that the release handle is closed. At this time,
the latch boss locks the optical module. After the optical module is inserted, try pulling it
out to see if it is installed in position. If the optical module cannot be pulled out, it is secured.
Close the release handle
Cleaning tissues must be prepared on site. You need to clean the optical connector before
inserting it in the receptacle. This protects the receptacle against the contamination on the
surface of the optical connector.

Place at least three cleaning tissues on the work bench. As shown in
optical connector from left to right or from right to left on a cleaning tissue, and then move the
connector end to the unused part of the cleaning tissue to continue.
Cover an unused optical module with a protective cap to prevent dust, as shown in
