Introduction to the PXIe Chassis Installing PXI Modules in the Chassis
Although rare, it is possible to spread damage with the use of a single
defective module. If you have a module with an undetected damaged
connector and move it from slot to slot or from chassis to chassis, you might
be damaging every slot you slide the module into. Once a chassis' pins are
damaged in that slot, it is possible to damage a good module by sliding it into
one of the damaged slots.
Periodic chassis inspection
Depending on your use, you might never need to examine a chassis
backplane for bent pins. Perhaps you assemble a system once and then it is
never subsequently modified. This type of use does not require inspection.
However, if your chassis use pattern is to have modules inserted and removed
on a regular basis, and if it is done by many different people, you might find it
beneficial to periodically inspect all of your chassis backplanes.
How to inspect your chassis backplane for bent pins or debris
Remove all the modules from the chassis. Remove power. Move the chassis to
a well-lit bench and stand the chassis on end so that light shines down onto
the backplane. Visually inspect all the pins on the backplane. Verify the pins
are in straight rows. Look for discoloration resulting from an electrical short.
Look for and remove debris laying in the backplane connectors.
What to do if you find a bent pin
Send the chassis in for repair.
