Lexmark MS521 Service Manual

Low Insertion Force (LIF) connector
This FRU contains a Low Insertion Force (LIF) connector. Read the instructions before proceeding.
Warning—Potential Damage: When installing a cable into an LIF connector, care must be taken to avoid
bending the edges of the cables and damaging the contacts on the cables.
Inserting a cable into the LIF connector
1 Looking at the connector, take note on which side the contacts are located. Many boards will have the word
“contacts” stamped on them to indicate which side of the LIF has the contacts. When looking at the board,
take note that the contacts from the board to the connector are located on the side of the connector with
the contacts.
2 Insert the cable squarely into the connector.
Note: Verify that the cable is installed straight into the connector. If the cable is not installed properly,
then intermittent failures could occur.
