WARNING
When you insert or remove the module while backplane power
is on, an electrical arc can occur. This could cause an explosion

removed or the area is nonhazardous before proceeding.
Repeated electrical arcing causes excessive wear to contacts
on both module and its mating connector. Worn contacts may
create electrical resistance that can affect module operation.
