When installing an optical module, force it into position. If a crack sound is heard or a slight
tremor is felt, it indicates that the latch boss is secured. When the latch boss is not secured,
the connecting finger is unstably connected to the connector on the board, and the link may
become Up. On the condition that the optical module tremors or collides with another
object, however, 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
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.
Clean tissues must be prepared for the deployment on site. You need to clean the optical
connector before inserting it in the receptacle. This protects the receptacle against the
contamination on the end surface of the optical connector.
NOTE
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 can be used once for cleaning an optical connector.
To prevent contamination, the optical module should be covered with either a dust cap or
an optical connector.
