WARNING: When you insert or remove the module while
backplane power is on, an electrical arc can occur. This could
cause an explosion in hazardous location installations. Be sure that
power is removed or the area is nonhazardous before proceeding.
Repeated electrical arcing causes excessive wear to contacts on
both the module and its mating connector. Worn contacts may
create electrical resistance that can affect module operation.
