Simple repair methods

Precautions
Proper ESD precautions must be followed.
Make sure that you have adequate space to access the backplane area and that you have
good light sources so that you can see what you are doing.
Visual examination
Visually examine the connector pins to determine which pins may have been damaged and
the degree of the damage. Pins that have been slightly bent may be carefully restored to
their initial straight position. Examine both sides of the backplane to determine if the
press-fit termination has been disturbed. These pins depend on an undisturbed interference
fit between the terminal body and the plated-through hole in the backplane to create a
reliable connection.
If the visual examination suggests that the connector pins are loose or are damaged beyond
repair, replace the connector pin.
METRAL backplane pins
Follow the instructions and use the tools provided in the MT370-01 Shelf Level Press-Fit
Repair Kit to straighten METRAL pins which may have been bent out of position.
Guide pins and keying pins
If a stainless steel guide pin or keying pin has been bent out of alignment, attempts to
straighten it may damage the backplane. The recommended alternative is to replace the
bent pin.

down to ensure no further damage to the equipment or to the person doing the
repair. If service cannot be removed or rerouted, contact your next level of
support before proceeding.
