4.1.2 Connector Types
There are two kinds of connectors on the main board:
•
Connectors with no locks
Unplug the cable by simply pulling out the cable from the connector.
•
Connectors with locks
You can use a plastic stick to lock and unlock connectors with locks.
The cables used here are special FPC (flexible printed-circuit) cables, which are
more delicate than normal plastic-enclosed cables. Therefore, to prevent
damage, make sure that you unlock the connectors before pulling out the cables.
Do not force cables out of the connectors.
CONNECTORS WITH LOCKS
•
Unplugging the Cable
To unplug the cable, first unlock the connector by pulling up the two clasps on both sides of
the connector with a plastic stick. Then carefully pull out the cable from the connector.
•
Plugging the Cable
To plug the cable back, first make sure that the connector is unlocked, then plug the cable into
the connector. With a plastic stick, press the two clasps on both sides of the connector to
secure the cables in place.
