CA UTION
The QSFP28 and QSFP-DD modules will get very hot during operation. To
prevent injuries, do not touch the module shells when removing the modules.
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.
If you cannot push the optical module into an optical module cage any
longer, the optical module is in good contact with the board connector.
When installing a CFP optical module, push the module panel horizontally
into the connector using even force with both thumbs. After the module is
inserted, push the module slightly to ensure that it has reached the stop
position.
After the CFP optical module is securely inserted, tighten the two screw rods
of the module alternately. To prevent the module from getting loosened due
to vibration or collision, you are advised to use a screwdriver to tighten the
screw rods.
